  • Contemporary Views

Nature refers to how genetics influence an individual's personality, whereas nurture refers to how their environment (including relationships and experiences) impacts their development. Whether nature or nurture plays a bigger role in personality and development is one of the oldest philosophical debates within the field of psychology .

Learn how each is defined, along with why the issue of nature vs. nurture continues to arise. We also share a few examples of when arguments on this topic typically occur, how the two factors interact with each other, and contemporary views that exist in the debate of nature vs. nurture as it stands today.

Nature and Nurture Defined

To better understand the nature vs. nurture argument, it helps to know what each of these terms means.

  • Nature refers largely to our genetics . It includes the genes we are born with and other hereditary factors that can impact how our personality is formed and influence the way that we develop from childhood through adulthood.
  • Nurture encompasses the environmental factors that impact who we are. This includes our early childhood experiences, the way we were raised , our social relationships, and the surrounding culture.

A few biologically determined characteristics include genetic diseases, eye color, hair color, and skin color. Other characteristics are tied to environmental influences, such as how a person behaves, which can be influenced by parenting styles and learned experiences.

For example, one child might learn through observation and reinforcement to say please and thank you. Another child might learn to behave aggressively by observing older children engage in violent behavior on the playground.

The Debate of Nature vs. Nurture

The nature vs. nurture debate centers on the contributions of genetics and environmental factors to human development. Some philosophers, such as Plato and Descartes, suggested that certain factors are inborn or occur naturally regardless of environmental influences.

Advocates of this point of view believe that all of our characteristics and behaviors are the result of evolution. They contend that genetic traits are handed down from parents to their children and influence the individual differences that make each person unique.

Other well-known thinkers, such as John Locke, believed in what is known as tabula rasa which suggests that the mind begins as a blank slate . According to this notion, everything that we are is determined by our experiences.

Behaviorism is a good example of a theory rooted in this belief as behaviorists feel that all actions and behaviors are the results of conditioning. Theorists such as John B. Watson believed that people could be trained to do and become anything, regardless of their genetic background.

People with extreme views are called nativists and empiricists. Nativists take the position that all or most behaviors and characteristics are the result of inheritance. Empiricists take the position that all or most behaviors and characteristics result from learning.

Examples of Nature vs. Nurture

One example of when the argument of nature vs. nurture arises is when a person achieves a high level of academic success . Did they do so because they are genetically predisposed to elevated levels of intelligence, or is their success a result of an enriched environment?

The argument of nature vs. nurture can also be made when it comes to why a person behaves in a certain way. If a man abuses his wife and kids, for instance, is it because he was born with violent tendencies, or is violence something he learned by observing others in his life when growing up?

Nature vs. Nurture in Psychology

Throughout the history of psychology , the debate of nature vs. nurture has continued to stir up controversy. Eugenics, for example, was a movement heavily influenced by the nativist approach.

Psychologist Francis Galton coined the terms 'nature versus nurture' and 'eugenics' and believed that intelligence resulted from genetics. Galton also felt that intelligent individuals should be encouraged to marry and have many children, while less intelligent individuals should be discouraged from reproducing.

The value placed on nature vs. nurture can even vary between the different branches of psychology , with some branches taking a more one-sided approach. In biopsychology , for example, researchers conduct studies exploring how neurotransmitters influence behavior, emphasizing the role of nature.

In social psychology , on the other hand, researchers might conduct studies looking at how external factors such as peer pressure and social media influence behaviors, stressing the importance of nurture. Behaviorism is another branch that focuses on the impact of the environment on behavior.

Nature vs. Nurture in Child Development

Some psychological theories of child development place more emphasis on nature and others focus more on nurture. An example of a nativist theory involving child development is Chomsky's concept of a language acquisition device (LAD). According to this theory, all children are born with an instinctive mental capacity that allows them to both learn and produce language.

An example of an empiricist child development theory is Albert Bandura's social learning theory . This theory says that people learn by observing the behavior of others. In his famous Bobo doll experiment , Bandura demonstrated that children could learn aggressive behaviors simply by observing another person acting aggressively.

Nature vs. Nurture in Personality Development

There is also some argument as to whether nature or nurture plays a bigger role in the development of one's personality. The answer to this question varies depending on which personality development theory you use.

According to behavioral theories, our personality is a result of the interactions we have with our environment, while biological theories suggest that personality is largely inherited. Then there are psychodynamic theories of personality that emphasize the impact of both.

Nature vs. Nurture in Mental Illness Development

One could argue that either nature or nurture contributes to mental health development. Some causes of mental illness fall on the nature side of the debate, including changes to or imbalances with chemicals in the brain. Genetics can also contribute to mental illness development, increasing one's risk of a certain disorder or disease.

Mental disorders with some type of genetic component include autism , attention-deficit hyperactivity disorder (ADHD), bipolar disorder , major depression , and schizophrenia .

Other explanations for mental illness are environmental. This includes being exposed to environmental toxins, such as drugs or alcohol, while still in utero. Certain life experiences can also influence mental illness development, such as witnessing a traumatic event, leading to the development of post-traumatic stress disorder (PTSD).

Nature vs. Nurture in Mental Health Therapy

Different types of mental health treatment can also rely more heavily on either nature or nurture in their treatment approach. One of the goals of many types of therapy is to uncover any life experiences that may have contributed to mental illness development (nurture).

However, genetics (nature) can play a role in treatment as well. For instance, research indicates that a person's genetic makeup can impact how their body responds to antidepressants. Taking this into consideration is important for getting that person the help they need.

Interaction Between Nature and Nurture

Which is stronger: nature or nurture? Many researchers consider the interaction between heredity and environment—nature with nurture as opposed to nature versus nurture—to be the most important influencing factor of all.

For example, perfect pitch is the ability to detect the pitch of a musical tone without any reference. Researchers have found that this ability tends to run in families and might be tied to a single gene. However, they've also discovered that possessing the gene is not enough as musical training during early childhood is needed for this inherited ability to manifest itself.

Height is another example of a trait influenced by an interaction between nature and nurture. A child might inherit the genes for height. However, if they grow up in a deprived environment where proper nourishment isn't received, they might never attain the height they could have had if they'd grown up in a healthier environment.

A newer field of study that aims to learn more about the interaction between genes and environment is epigenetics . Epigenetics seeks to explain how environment can impact the way in which genes are expressed.

Some characteristics are biologically determined, such as eye color, hair color, and skin color. Other things, like life expectancy and height, have a strong biological component but are also influenced by environmental factors and lifestyle.

Contemporary Views of Nature vs. Nurture

Most experts recognize that neither nature nor nurture is stronger than the other. Instead, both factors play a critical role in who we are and who we become. Not only that but nature and nurture interact with each other in important ways all throughout our lifespan.

As a result, many in this field are interested in seeing how genes modulate environmental influences and vice versa. At the same time, this debate of nature vs. nurture still rages on in some areas, such as in the origins of homosexuality and influences on intelligence .

While a few people take the extreme nativist or radical empiricist approach, the reality is that there is not a simple way to disentangle the multitude of forces that exist in personality and human development. Instead, these influences include genetic factors, environmental factors, and how each intermingles with the other.

The nature vs. nurture debate in psychology concerns the relative importance of an individual’s innate qualities (nature) versus personal experiences (nurture) in determining or causing individual differences in physical and behavioral traits. While early theories favored one factor over the other, contemporary views recognize a complex interplay between genes and environment in shaping behavior and development.

Key Takeaways

  • Nature is what we think of as pre-wiring and is influenced by genetic inheritance and other biological factors.
  • Nurture is generally taken as the influence of external factors after conception, e.g., the product of exposure, life experiences, and learning on an individual.
  • Behavioral genetics has enabled psychology to quantify the relative contribution of nature and nurture concerning specific psychological traits.
  • Instead of defending extreme nativist or nurturist views, most psychological researchers are now interested in investigating how nature and nurture interact in a host of qualitatively different ways.
  • For example, epigenetics is an emerging area of research that shows how environmental influences affect the expression of genes.
The nature-nurture debate is concerned with the relative contribution that both influences make to human behavior, such as personality, cognitive traits, temperament and psychopathology.

Examples of Nature vs. Nurture

Nature vs. nurture in child development.

In child development, the nature vs. nurture debate is evident in the study of language acquisition . Researchers like Chomsky (1957) argue that humans are born with an innate capacity for language (nature), known as universal grammar, suggesting that genetics play a significant role in language development.

Conversely, the behaviorist perspective, exemplified by Skinner (1957), emphasizes the role of environmental reinforcement and learning (nurture) in language acquisition.

Twin studies have provided valuable insights into this debate, demonstrating that identical twins raised apart may share linguistic similarities despite different environments, suggesting a strong genetic influence (Bouchard, 1979)

However, environmental factors, such as exposure to language-rich environments, also play a crucial role in language development, highlighting the intricate interplay between nature and nurture in child development.

Nature vs. Nurture in Personality Development

The nature vs. nurture debate in personality psychology centers on the origins of personality traits. Twin studies have shown that identical twins reared apart tend to have more similar personalities than fraternal twins, indicating a genetic component to personality (Bouchard, 1994).

However, environmental factors, such as parenting styles, cultural influences, and life experiences, also shape personality.

For example, research by Caspi et al. (2003) demonstrated that a particular gene (MAOA) can interact with childhood maltreatment to increase the risk of aggressive behavior in adulthood.

This highlights that genetic predispositions and environmental factors contribute to personality development, and their interaction is complex and multifaceted.

Nature vs. Nurture in Mental Illness Development

The nature vs. nurture debate in mental health explores the etiology of depression. Genetic studies have identified specific genes associated with an increased vulnerability to depression, indicating a genetic component (Sullivan et al., 2000).

However, environmental factors, such as adverse life events and chronic stress during childhood, also play a significant role in the development of depressive disorders (Dube et al.., 2002; Keller et al., 2007)

The diathesis-stress model posits that individuals inherit a genetic predisposition (diathesis) to a disorder, which is then activated or exacerbated by environmental stressors (Monroe & Simons, 1991).

This model illustrates how nature and nurture interact to influence mental health outcomes.

Nature vs. Nurture of Intelligence

The nature vs. nurture debate in intelligence examines the relative contributions of genetic and environmental factors to cognitive abilities.

Intelligence is highly heritable, with about 50% of variance in IQ attributed to genetic factors, based on studies of twins, adoptees, and families (Plomin & Spinath, 2004).

Heritability of intelligence increases with age, from about 20% in infancy to as high as 80% in adulthood, suggesting amplifying effects of genes over time.

However, environmental influences, such as access to quality education and stimulating environments, also significantly impact intelligence.

Shared environmental influences like family background are more influential in childhood, whereas non-shared experiences are more important later in life.

Research by Flynn (1987) showed that average IQ scores have increased over generations, suggesting that environmental improvements, known as the Flynn effect , can lead to substantial gains in cognitive abilities.

Molecular genetics provides tools to identify specific genes and understand their pathways and interactions. However, progress has been slow for complex traits like intelligence. Identified genes have small effect sizes (Plomin & Spinath, 2004).

Overall, intelligence results from complex interplay between genes and environment over development. Molecular genetics offers promise to clarify these mechanisms. The nature vs nurture debate is outdated – both play key roles.

Nativism (Extreme Nature Position)

It has long been known that certain physical characteristics are biologically determined by genetic inheritance.

Color of eyes, straight or curly hair, pigmentation of the skin, and certain diseases (such as Huntingdon’s chorea) are all a function of the genes we inherit.

eye color genetics

These facts have led many to speculate as to whether psychological characteristics such as behavioral tendencies, personality attributes, and mental abilities are also “wired in” before we are even born.

Those who adopt an extreme hereditary position are known as nativists.  Their basic assumption is that the characteristics of the human species as a whole are a product of evolution and that individual differences are due to each person’s unique genetic code.

In general, the earlier a particular ability appears, the more likely it is to be under the influence of genetic factors. Estimates of genetic influence are called heritability.

Examples of extreme nature positions in psychology include Chomsky (1965), who proposed language is gained through the use of an innate language acquisition device. Another example of nature is Freud’s theory of aggression as being an innate drive (called Thanatos).

Characteristics and differences that are not observable at birth, but which emerge later in life, are regarded as the product of maturation. That is to say, we all have an inner “biological clock” which switches on (or off) types of behavior in a pre-programmed way.

The classic example of the way this affects our physical development are the bodily changes that occur in early adolescence at puberty.

However, nativists also argue that maturation governs the emergence of attachment in infancy , language acquisition , and even cognitive development .

Empiricism (Extreme Nurture Position)

At the other end of the spectrum are the environmentalists – also known as empiricists (not to be confused with the other empirical/scientific  approach ).

Their basic assumption is that at birth, the human mind is a tabula rasa (a blank slate) and that this is gradually “filled” as a result of experience (e.g., behaviorism ).

From this point of view, psychological characteristics and behavioral differences that emerge through infancy and childhood are the results of learning.  It is how you are brought up (nurture) that governs the psychologically significant aspects of child development and the concept of maturation applies only to the biological.

For example, Bandura’s (1977) social learning theory states that aggression is learned from the environment through observation and imitation. This is seen in his famous bobo doll experiment (Bandura, 1961).

bobo doll experiment

Also, Skinner (1957) believed that language is learned from other people via behavior-shaping techniques.

Evidence for Nature

  • Biological Approach
  • Biology of Gender
  • Medical Model

Freud (1905) stated that events in our childhood have a great influence on our adult lives, shaping our personality.

He thought that parenting is of primary importance to a child’s development , and the family as the most important feature of nurture was a common theme throughout twentieth-century psychology (which was dominated by environmentalists’ theories).

Behavioral Genetics

Researchers in the field of behavioral genetics study variation in behavior as it is affected by genes, which are the units of heredity passed down from parents to offspring.

“We now know that DNA differences are the major systematic source of psychological differences between us. Environmental effects are important but what we have learned in recent years is that they are mostly random – unsystematic and unstable – which means that we cannot do much about them.” Plomin (2018, xii)

Behavioral genetics has enabled psychology to quantify the relative contribution of nature and nurture with regard to specific psychological traits. One way to do this is to study relatives who share the same genes (nature) but a different environment (nurture). Adoption acts as a natural experiment which allows researchers to do this.

Empirical studies have consistently shown that adoptive children show greater resemblance to their biological parents, rather than their adoptive, or environmental parents (Plomin & DeFries, 1983; 1985).

Another way of studying heredity is by comparing the behavior of twins, who can either be identical (sharing the same genes) or non-identical (sharing 50% of genes). Like adoption studies, twin studies support the first rule of behavior genetics; that psychological traits are extremely heritable, about 50% on average.

The Twins in Early Development Study (TEDS) revealed correlations between twins on a range of behavioral traits, such as personality (empathy and hyperactivity) and components of reading such as phonetics (Haworth, Davis, Plomin, 2013; Oliver & Plomin, 2007; Trouton, Spinath, & Plomin, 2002).

Implications

Jenson (1969) found that the average I.Q. scores of black Americans were significantly lower than whites he went on to argue that genetic factors were mainly responsible – even going so far as to suggest that intelligence is 80% inherited.

The storm of controversy that developed around Jenson’s claims was not mainly due to logical and empirical weaknesses in his argument. It was more to do with the social and political implications that are often drawn from research that claims to demonstrate natural inequalities between social groups.

For many environmentalists, there is a barely disguised right-wing agenda behind the work of the behavioral geneticists.  In their view, part of the difference in the I.Q. scores of different ethnic groups are due to inbuilt biases in the methods of testing.

More fundamentally, they believe that differences in intellectual ability are a product of social inequalities in access to material resources and opportunities.  To put it simply children brought up in the ghetto tend to score lower on tests because they are denied the same life chances as more privileged members of society.

Now we can see why the nature-nurture debate has become such a hotly contested issue.  What begins as an attempt to understand the causes of behavioral differences often develops into a politically motivated dispute about distributive justice and power in society.

What’s more, this doesn’t only apply to the debate over I.Q.  It is equally relevant to the psychology of sex and gender , where the question of how much of the (alleged) differences in male and female behavior is due to biology and how much to culture is just as controversial.

Polygenic Inheritance

Rather than the presence or absence of single genes being the determining factor that accounts for psychological traits, behavioral genetics has demonstrated that multiple genes – often thousands, collectively contribute to specific behaviors.

Thus, psychological traits follow a polygenic mode of inheritance (as opposed to being determined by a single gene). Depression is a good example of a polygenic trait, which is thought to be influenced by around 1000 genes (Plomin, 2018).

This means a person with a lower number of these genes (under 500) would have a lower risk of experiencing depression than someone with a higher number.

The Nature of Nurture

Nurture assumes that correlations between environmental factors and psychological outcomes are caused environmentally. For example, how much parents read with their children and how well children learn to read appear to be related. Other examples include environmental stress and its effect on depression.

However, behavioral genetics argues that what look like environmental effects are to a large extent really a reflection of genetic differences (Plomin & Bergeman, 1991).

People select, modify and create environments correlated with their genetic disposition. This means that what sometimes appears to be an environmental influence (nurture) is a genetic influence (nature).

So, children that are genetically predisposed to be competent readers, will be happy to listen to their parents read them stories, and be more likely to encourage this interaction.

Interaction Effects

However, in recent years there has been a growing realization that the question of “how much” behavior is due to heredity and “how much” to the environment may itself be the wrong question.

Take intelligence as an example. Like almost all types of human behavior, it is a complex, many-sided phenomenon which reveals itself (or not!) in a great variety of ways.

The “how much” question assumes that psychological traits can all be expressed numerically and that the issue can be resolved in a quantitative manner.

Heritability statistics revealed by behavioral genetic studies have been criticized as meaningless, mainly because biologists have established that genes cannot influence development independently of environmental factors; genetic and nongenetic factors always cooperate to build traits. The reality is that nature and culture interact in a host of qualitatively different ways (Gottlieb, 2007; Johnston & Edwards, 2002).

Instead of defending extreme nativist or nurturist views, most psychological researchers are now interested in investigating how nature and nurture interact.

For example, in psychopathology , this means that both a genetic predisposition and an appropriate environmental trigger are required for a mental disorder to develop. For example, epigenetics state that environmental influences affect the expression of genes.

epigenetics

What is Epigenetics?

Epigenetics is the term used to describe inheritance by mechanisms other than through the DNA sequence of genes. For example, features of a person’s physical and social environment can effect which genes are switched-on, or “expressed”, rather than the DNA sequence of the genes themselves.

Stressors and memories can be passed through small RNA molecules to multiple generations of offspring in ways that meaningfully affect their behavior.

One such example is what is known as the Dutch Hunger Winter, during last year of the Second World War. What they found was that children who were in the womb during the famine experienced a life-long increase in their chances of developing various health problems compared to children conceived after the famine.

Epigenetic effects can sometimes be passed from one generation to the next, although the effects only seem to last for a few generations. There is some evidence that the effects of the Dutch Hunger Winter affected grandchildren of women who were pregnant during the famine.

Therefore, it makes more sense to say that the difference between two people’s behavior is mostly due to hereditary factors or mostly due to environmental factors.

This realization is especially important given the recent advances in genetics, such as polygenic testing.  The Human Genome Project, for example, has stimulated enormous interest in tracing types of behavior to particular strands of DNA located on specific chromosomes.

If these advances are not to be abused, then there will need to be a more general understanding of the fact that biology interacts with both the cultural context and the personal choices that people make about how they want to live their lives.

There is no neat and simple way of unraveling these qualitatively different and reciprocal influences on human behavior.

Epigenetics: Licking Rat Pups

Michael Meaney and his colleagues at McGill University in Montreal, Canada conducted the landmark epigenetic study on mother rats licking and grooming their pups.

This research found that the amount of licking and grooming received by rat pups during their early life could alter their epigenetic marks and influence their stress responses in adulthood.

Pups that received high levels of maternal care (i.e., more licking and grooming) had a reduced stress response compared to those that received low levels of maternal care.

Meaney’s work with rat maternal behavior and its epigenetic effects has provided significant insights into the understanding of early-life experiences, gene expression, and adult behavior.

It underscores the importance of the early-life environment and its long-term impacts on an individual’s mental health and stress resilience.

Epigenetics: The Agouti Mouse Study

Waterland and Jirtle’s 2003 study on the Agouti mouse is another foundational work in the field of epigenetics that demonstrated how nutritional factors during early development can result in epigenetic changes that have long-lasting effects on phenotype.

In this study, they focused on a specific gene in mice called the Agouti viable yellow (A^vy) gene. Mice with this gene can express a range of coat colors, from yellow to mottled to brown.

This variation in coat color is related to the methylation status of the A^vy gene: higher methylation is associated with the brown coat, and lower methylation with the yellow coat.

Importantly, the coat color is also associated with health outcomes, with yellow mice being more prone to obesity, diabetes, and tumorigenesis compared to brown mice.

Waterland and Jirtle set out to investigate whether maternal diet, specifically supplementation with methyl donors like folic acid, choline, betaine, and vitamin B12, during pregnancy could influence the methylation status of the A^vy gene in offspring.

Key findings from the study include:

Dietary Influence : When pregnant mice were fed a diet supplemented with methyl donors, their offspring had an increased likelihood of having the brown coat color. This indicated that the supplemented diet led to an increased methylation of the A^vy gene.

Health Outcomes : Along with the coat color change, these mice also had reduced risks of obesity and other health issues associated with the yellow phenotype.

Transgenerational Effects : The study showed that nutritional interventions could have effects that extend beyond the individual, affecting the phenotype of the offspring.

The implications of this research are profound. It highlights how maternal nutrition during critical developmental periods can have lasting effects on offspring through epigenetic modifications, potentially affecting health outcomes much later in life.

The study also offers insights into how dietary and environmental factors might contribute to disease susceptibility in humans.

In the nature vs. nurture debate, “nature” refers to the influence of genetics, innate qualities, and biological factors on human development, behavior, and traits. It emphasizes the role of hereditary factors in shaping who we are.

What does nurture refer to in the nature vs. nurture debate?

In the nature vs. nurture debate, “nurture” refers to the influence of the environment, upbringing, experiences, and social factors on human development, behavior, and traits. It emphasizes the role of external factors in shaping who we are.

Why is it important to determine the contribution of heredity (nature) and environment (nurture) in human development?

Determining the contribution of heredity and environment in human development is crucial for understanding the complex interplay between genetic factors and environmental influences. It helps identify the relative significance of each factor, informing interventions, policies, and strategies to optimize human potential and address developmental challenges.

Epigenetics and Child Development: How Children’s Experiences Affect Their Genes

For more information about epigenetics, please scroll down below the infographic .

What is epigenetics? infographic

New scientific research shows that environmental influences can actually affect whether and how genes are expressed. In fact, scientists have discovered that early experiences can determine how genes are turned on and off and even whether some are expressed at all. Thus, the old ideas that genes are “set in stone” or that they alone determine development have been disproven. Nature vs. Nurture is no longer a debate—it’s nearly always both!

More Information on Epigenetics Deep Dive: Gene-Environment Interaction Learn more about the physical and chemical processes that take place as part of the creation of the epigenome. Working Paper 10: Early Experiences Can Alter Gene Expression and Affect Long-Term Development This in-depth working paper explains how genes and the environment interact, and gives recommendations for ways that caregivers and policymakers can effectively respond to the science.

During development, the DNA that makes up our genes accumulates chemical marks that determine how much or little of the genes is expressed. This collection of chemical marks is known as the “ epigenome .” The different experiences children have rearrange those chemical marks. This explains why genetically identical twins can exhibit different behaviors, skills, health, and achievement.

Correcting Popular Misrepresentations of Science

Until recently, the influences of genes were thought to be set, and the effects of children’s experiences and environments on brain architecture and long-term physical and mental health outcomes remained a mystery. That lack of understanding led to several misleading conclusions about the degree to which negative and positive environmental factors and experiences can affect the developing fetus and young child. The following misconceptions are particularly important to set straight.

  • Contrary to popular belief, the genes inherited from one’s parents do not set a child’s future development in stone. Variations in DNA sequences between individuals certainly influence the way in which genes are expressed and how the proteins encoded by those genes will function. But that is only part of the story—the environment in which one develops , before and soon after birth, provides powerful experiences that chemically modify certain genes which, in turn, define how much and when they are expressed. Thus, while genetic factors exert potent influences, environmental factors have the ability to alter the genes that were inherited.
  • Although frequently misunderstood, adverse fetal and early childhood experiences can—and do—lead to physical and chemical changes in the brain that can last a lifetime. Injurious experiences , such as malnutrition, exposure to chemical toxins or drugs, and toxic stress before birth or in early childhood are not “forgotten,” but rather are built into the architecture of the developing brain through the epigenome. The “biological memories” associated with these epigenetic changes can affect multiple organ systems and increase the risk not only for poor physical and mental health outcomes but also for impairments in future learning capacity and behavior.
  • Despite some marketing claims to the contrary, the ability of so-called enrichment programs to enhance otherwise healthy brain development is not known. While parents and policymakers might hope that playing Mozart recordings to newborns will produce epigenetic changes that enhance cognitive development, there is absolutely no scientific evidence that such exposure will shape the epigenome or enhance brain function. What research has shown is that specific epigenetic modifications do occur in brain cells as cognitive skills like learning and memory develop, and that repeated activation of brain circuits dedicated to learning and memory through interaction with the environment, such as reciprocal “ serve and return ” interaction with adults, facilitates these positive epigenetic modifications. We also know that sound maternal and fetal nutrition , combined with positive social-emotional support of children through their family and community environments, will reduce the likelihood of negative epigenetic modifications that increase the risk of later physical and mental health impairments.

The epigenome can be affected by positive experiences, such as supportive relationships and opportunities for learning, or negative influences, such as environmental toxins or stressful life circumstances, which leave a unique epigenetic “signature” on the genes. These signatures can be temporary or permanent and both types affect how easily the genes are switched on or off. Recent research demonstrates that there may be ways to reverse certain negative changes and restore healthy functioning, but that takes a lot more effort, may not be successful at changing all aspects of the signatures, and is costly. Thus, the very best strategy is to support responsive relationships and reduce stress to build strong brains from the beginning, helping children grow up to be healthy, productive members of society.

“Epigenetics” is an emerging area of scientific research that shows how environmental influences—children’s experiences—actually affect the expression of their genes.

This means the old idea that genes are “set in stone” has been disproven. Nature vs. Nurture is no longer a debate. It’s nearly always both!

During development, the DNA that makes up our genes accumulates chemical marks that determine how much or little of the genes is expressed. This collection of chemical marks is known as the “epigenome.” The different experiences children have rearrange those chemical marks. This explains why genetically identical twins can exhibit different behaviors, skills, health, and achievement.

Epigenetics explains how early experiences can have lifelong impacts.

The genes children inherit from their biological parents provide information that guides their development. For example, how tall they could eventually become or the kind of temperament they could have.

When experiences during development rearrange the epigenetic marks that govern gene expression, they can change whether and how genes release the information they carry.

Thus, the epigenome can be affected by positive experiences, such as supportive relationships and opportunities for learning, or negative influences, such as environmental toxins or stressful life circumstances, which leave a unique epigenetic “signature” on the genes. These signatures can be temporary or permanent and both types affect how easily the genes are switched on or off. Recent research demonstrates that there may be ways to reverse certain negative changes and restore healthy functioning. But the very best strategy is to support responsive relationships and reduce stress to build strong brains from the beginning.

Young brains are particularly sensitive to epigenetic changes.

Experiences very early in life, when the brain is developing most rapidly, cause epigenetic adaptations that influence whether, when, and how genes release their instructions for building future capacity for health, skills, and resilience. That’s why it’s crucial to provide supportive and nurturing experiences for young children in the earliest years.

Services such as high-quality health care for all pregnant women, infants, and toddlers, as well as support for new parents and caregivers can—quite literally— affect the chemistry around children’s genes. Supportive relationships and rich learning experiences generate positive epigenetic signatures that activate genetic potential.

Nature vs. Nurture Child Development: Exploring Key Differences

October 8, 2020 

nature and nurture child development essay

Whether a child’s personality traits and behavioral tendencies are the sole result of heredity or a consequence of their upbringing is an age-old debate. Much of the controversy in nature vs. nurture child development is the result of a misunderstanding about genetics: the mistaken belief that fate and genetics are synonymous.

In fact, children’s genetic makeup is determined in many ways by their own experiences in their environment. The burgeoning field of epigenetics studies the effect of children’s early experiences on the chemical marks that accumulate in DNA and determine how much of a specific gene will be expressed, as the child development site First Five Years explains. All of these marks combined make up the epigenome; epigenetics is the study of these marks and their impact on children and adults.

A group of children playing tug of war in the park

Epigenetics and related fields in child development promise to give parents and educators new insights into how and why certain genes are expressed and others aren’t. Degree programs such as  Maryville University’s online Bachelor of Arts in Human Development and Family Studies  explore these areas to prepare students for careers that help families overcome challenges in their lives.

Learn how people develop physically, emotionally and socially within the context of family and society

The online BA in human development and family studies from Maryville University prepares you with the knowledge and skills related to child development, family dynamics and interpersonal relationships. No SAT or ACT scores required.

  • Benefit from a curriculum that follows the 10 content areas of the National Council on Family Relations (NCFR).
  • Engage in a range of relevant course topics, from interpersonal relationships to medical terminology.

Definitions: Nature vs. Nurture Child Development

In the nature vs. nurture debate, “nature” is defined as all genes and hereditary factors that contribute to a person’s unique physical appearance, personality, and physiology. “Nurture” is defined as the many environmental variables that affect a person, including their experiences in early childhood, family and social relationships, culture, and community.

Both nature and nurture are linked to the philosophical concepts of empiricism and rationalism.

  • Empiricists  believe that the ultimate source of all concepts and knowledge is our sense experience.
  • Rationalists  hold that the content of concepts and knowledge may at times surpass the information that sense experience alone provides. They also believe that some form of reasoning is the source of this added information about the world.

Most researchers in child development are more interested in how nature and nurture interact than in determining which of the two may predominate. For example, Simply Psychology places various approaches to psychology on a continuum:

  • At one end is the extreme nature position of  nativists , who believe that behavioral tendencies, personality, and mental abilities are determined solely by heredity.
  • At the opposite end is the extreme nurture position of  empiricists , who consider a person’s psychological and physiological makeup to be entirely the result of their sense experiences.

Between these two extremes are a number of fields that focus on the interplay of nature and nurture in child development. Among these are  behavioral genetics , which studies the genetic impact on variations in behavior, and  polygenic inheritance , which looks at the effect that large groups of genes collectively have on a person’s behavior.

Similarities Between Nature and Nurture Child Development

As researchers delve deeper into nature vs. nurture child development, they find that many aspects of development that were once thought to be determined by a child’s environment also have a genetic component, whereas others that were believed to be controlled solely by heredity are greatly influenced by external factors.

Today’s Parent  explains that many past studies on the effect of a child’s experiences and environment are flawed because it’s impossible for researchers to effectively control for genetics. Conversely, studies that claim parenting has no impact on a child’s development ignore the vital role that parents play in encouraging the best attributes and behaviors in their children — and discouraging harmful or negative behaviors.

Nature vs. Nurture: Influences Impacting Child Development

Genes determine certain human characteristics, such as eye and hair color and the incidence of genetic diseases. However, most human traits, including life expectancy, height, and weight, have both an environmental and genetic component. For example,  social learning theory  states that children learn by observing the behavior of others, so parenting styles and the child’s learned experiences determine whether they behave politely or aggressively in specific situations.

By contrast, learning’s genetic component encompasses the biological foundation of cognitive processes, as explained in  Frontiers in Psychology . Genetic and epigenetic contributions to the learning process are inheritable and interact with behavioral learning such as study habits and the availability of educational resources.

Nature vs. Nurture: Children’s Physical and Personality Traits

Two recent studies illustrate the important role of epigenetics in a child’s development. Researchers at the University of British Columbia, UCLA, and British Columbia Children’s Hospital discovered a genetic marker in a child’s DNA that serves as a chemical “clock” to indicate the child’s biological age, as reported in Science Daily.

In a separate study reported in  Psychology Today , researchers determined that toxin-related epigenetic changes, such as those caused by inhaling cigarette smoke, can be passed from parent to child genetically. The smoke triggers the expression of cancer-causing genes or suppresses the expression of those that protect against cancer. Children can inherit an epigenetic alteration from a parent.

Nature vs. Nurture: How Both Contribute to Child Development

The field of  behavioral genetics  studies how nature and nurture combine to affect a child’s development. It states that while genetics have a greater overall impact on a person’s makeup than their family environment does, most of an individual’s behavioral traits cannot be traced to specific genes or family characteristics. Instead, each human behavioral trait is associated with a great number of genetic variants, each of which contributes a very small amount to the expression of the trait.

Differences Between Nature and Nurture Child Development

Within the complex relationship between a child’s genetic makeup and learned experiences, distinctions can be drawn between the human traits that children are born with and those that result from their environment. The differences are evident in activities such as sleeping, crying, eating, socializing, and moving, all of which have clear nature and nurture components, as Firstcry Parenting explains.

Nature: Genetic and Hereditary Influences

A study of fraternal and identical twins found that babies’ sleeping patterns are determined primarily by genetics. Similarly, 60% of a baby’s temperament is set by their genetic makeup; whether they are sociable or shy is also primarily driven by genes. Also controlled primarily by heredity are the foods a baby prefers and whether the baby is active or sedentary.

Nurture: Environmental Influences

While genetics are key drivers of these and other aspects of a child’s development, that development is also influenced by what babies experience. For example, babies with poor sleep patterns can benefit from being exposed to sunlight during the day and by parents establishing a bedtime routine that induces better sleep. Whether a baby is easy to calm and soothe when crying is determined by genes, but swaddling, rocking, swaying, and other activities help overcome this genetic predisposition.

Nature’s Biological Psychology, Nurture’s Behaviorism

Biological psychology  examines thoughts, feelings, and behaviors from a physiological perspective, as Verywell Mind describes. The field studies how a person’s brain, nervous system, hormones, and other physical features affect behavior. It also studies the mechanisms of inheritance via genes on the behavioral likeness of identical twins, for example.

Conversely,  behaviorism  (also called  behavioral psychology ) considers how interaction with the environment can condition behavior. This field considers only observable behavior, believing that moods, cognition, and emotions are too subjective to be measurable. Types of conditioning include classical conditioning, which pairs a neutral stimulus with a naturally occurring stimulus until each evokes the same response, and operant or instrumental conditioning, which uses reinforcements and punishments to evoke the desired behavior.

Nature’s Scientific Influences, Nurture’s Social Constructs

While approaches to child development that emphasize nature over nurture may appear to be more grounded in science than in behavior modification, both nature and nurture have scientific foundations that are paired with environmental controls. In general, nature looks at the impact of such physical approaches as neurotransmitters and genome sequencing on child development, while nurture focuses on aspects such as peer pressure and social influences.

Studying the Relationships and Experiences That Shape Children and Families

New discoveries in epigenetics, behavioral psychology, and related areas make child development one of the most exciting fields of scientific research. Programs such as Maryville University’s  online Bachelor of Arts in Human Development and Family Studies  prepare students to help individuals, families, and communities promote healthy child development.

How do nature and nurture affect my child’s development?

Read time 5 minutes

Nurture - Nature

Are we fully responsible for our child’s personality and does what we do have much effect on it? Here Professor Angelica Ronald discusses evidence on nature versus nurture...

Blank slate or all in the genes?

In the past, children were viewed as ‘blank slates’ (Pinker, 2016) . The common view was that parents could 'mould' their child’s development through their actions. And this idea actually put a lot of pressure on parents. It suggested that any decision, whether good or bad, small or large, would shape their child.

We now know that children are not blank slates to be moulded by us. Their genetic makeup influences all aspects of their behaviour and personality (Knopik et al, 2017) . Starting from when they were first conceived, how a child develops and behaves is partly influenced by the genes they inherit.

On the other hand, genes are not completely in control of a child’s destiny – no behavioural or personality traits are 100% heritable (Polderman et al, 2015) . Genes give children a tendency towards certain ways of being, such as their sleeping behaviour or personality. But they also need an environment in which these genetic influences can play a role.

Both nature and nurture

Parenting does play an important role, just not in the way we originally believed. Nature and nurture both play a role.  How we act as parents as well as our child’s genes are strongly intertwined (Duncan, 2014) .

Each child responds to parenting in different ways . We know that children bring out different responses from their caregivers, partly as a result of their genetic makeup. This is called evocative gene-environment correlation (Plomin and Bergeman, 1991) .

Children will also seek out environments that suit their genetic background. This process is known as active gene–environment correlation (Plomin and Bergeman, 1991) .  

Why does it matter?

Information on how nature and nurture intertwine to influence children’s development can support families in several ways. As parents, it’s easy to take credit or to blame ourselves for every aspect of our children’s behaviour. Yet we cannot completely control a child’s development because part of it is influenced by the genes in their cells (Feero et al, 2010) . Realising this can help put our role as parents into perspective and respect our child as an individual.

The difference between siblings

Understanding the joint roles of nature and nurture also helps us to understand why siblings are sometimes very different from one another (Plomin and Daniels, 2011) . Siblings with the same mum and dad only share half of the genetic influences affecting their development. As such, siblings have a partly different genetic makeup, and this is one reason for sibling differences.

Siblings sometimes evoke different reactions from their parents. A parenting style might work for one child but not for another. Siblings might choose different environments to one another and show different tastes in toys, people, eating and napping habits, despite being raised by the same people.

Nature and nurture also help us understand why things run in families. This could be a behaviour like being very active, or a sleep pattern like needing less or more sleep than others. Research on genetic influences in infancy is still at an earlier stage than similar research on older age groups though (Papageorgiou and Ronald, 2017) .

If genes play a role, can I still help my child?

Yes, you can. Many things are partly down to our genes but this doesn't mean they can’t be supported or addressed through our environment. For example, sleep problems that persist into childhood are partly inherited (Barclay and Gregory, 2013) . Yet we know that changing something in our child’s environment, such as routine and using black-out blinds at night, can help to resolve these problems (Semple, 2008) .

It’s hard to pin down exactly how much of your child’s personality is down to nature and how much is nurture. We do know it’s a bit of both. The good news is you still play an important part in your child's development but take some pressure off yourself too. Not everything you do (or don't) will necessarily influence them or change who they are.

Nature and nurture as an enduring tension in the history of psychology.

Nature–nurture is a dichotomous way of thinking about the origins of human (and animal) behavior and development, where “nature” refers to native, inborn, causal factors that function independently of, or prior to, the experiences (“nurture”) of the organism. In psychology during the 19th century, nature-nurture debates were voiced in the language of instinct versus learning. In the first decades of the 20th century, it was widely assumed that that humans and animals entered the world with a fixed set of inborn instincts. But in the 1920s and again in the 1950s, the validity of instinct as a scientific construct was challenged on conceptual and empirical grounds. As a result, most psychologists abandoned using the term instinct but they did not abandon the validity of distinguishing between nature versus nurture. In place of instinct, many psychologists made a semantic shift to using terms like innate knowledge, biological maturation, and/or hereditary/genetic effects on development, all of which extend well into the 21st century. Still, for some psychologists, the earlier critiques of the instinct concept remain just as relevant to these more modern usages.

The tension in nature-nurture debates is commonly eased by claiming that explanations of behavior must involve reference to both nature-based and nurture-based causes. However, for some psychologists there is a growing pressure to see the nature–nurture dichotomy as oversimplifying the development of behavior patterns. The division is seen as both arbitrary and counterproductive. Rather than treat nature and nurture as separable causal factors operating on development, they treat nature-nurture as a distinction between product (nature) versus process (nurture). Thus there has been a longstanding tension about how to define, separate, and balance the effects of nature and nurture.

Nature and Nurture in Development

The oldest and most persistent ways to frame explanations about the behavioral and mental development of individuals is to distinguish between two separate sources of developmental causation: (a) intrinsic, preformed, or predetermined causes (“nature”) versus (b) extrinsic, experiential, or environmental causes (“nurture”). Inputs from these two sources are thought to add their own contribution to development (see Figure 1 ).

Figure 1. The traditional view of nature and nurture as separate causes of development. In the traditional view, nature and nurture are treated as independent causal influences that combine during development to generate outcomes. Note that, during development, the effects of nature and nurture (shown in horizontal crossing lines) remain independent so that their effects on outcomes are theoretically separable.

Because some traits seem to derive more from one source than the other, much of the tension associated with the nature–nurture division deals with disagreements about how to balance the roles of nature and nurture in the development of a trait.

Evidence of Nature in Development

Evidence to support the nature–nurture division usually derives from patterns of behavior that suggest a limited role of environmental causation, thus implying some effect of nature by default. Table 1 depicts some common descriptors and conditions used to infer that some preference, knowledge, or skill is nature based.

Table 1. Common Descriptors and Associated Conditions for Inferring the Effects of Nature on Development

It is important to reiterate that nature-based causation (e.g., genetic determination) is inferred from these observations. Such inferences can generate tension because each of the observations listed here can be explained by nurture-based (environmental) factors. Confusion can also arise when evidence of one descriptor (e.g., being hereditary) is erroneously used to justify a different usage (e.g., that the trait is unlearned).

The Origins of Nature Versus Nurture

For much of recorded history, the distinction between nature and nurture was a temporal divide between what a person is innately endowed with at birth, prior to experience (nature), and what happens thereafter (nurture). It was not until the 19th century that the temporal division was transformed into a material division of causal influences (Keller, 2010 ). New views about heredity and Darwinian evolution justified distinguishing between native traits and genetic causes from acquired traits and environmental causes. More so than before, the terms nature and nurture were often juxtaposed in an opposition famously described by Sir Francis Galton ( 1869 ) as that between “nature versus nurture.”

Galton began writing about heredity in the mid-1860s. He believed we would discover laws governing the transmission of mental as well as physical qualities. Galton’s take on mental heredity, however, was forged by his desire to improve the human race in a science he would later call “eugenics.” In the mid- 19th century , British liberals assumed humans were equivalent at birth. Their social reform efforts were geared to enhancing educational opportunities and improving living conditions. Galton, a political conservative, opposed the notion of natural equality, arguing instead that people were inherently different at birth (Cowan, 2016 ), and that these inherited mental and behavioral inequalities were transmitted through lineages like physical qualities. Because Galton opposed the widely held Lamarckian idea that the qualities acquired in one’s lifetime could modify the inherited potential of subsequent generations, he believed long-lasting improvement of the human stock would only come by controlling breeding practices.

To explain the biological mechanisms of inheritance, Galton joined a growing trend in the 1870s to understand inheritance as involving the transmission of (hypothetical) determinative, germinal substances across generations. Foreshadowing a view that would later become scientific orthodoxy, Galton believed these germinal substances to be uninfluenced by the experiences of the organism. His theory of inheritance, however, was speculative. Realizing he was not equipped to fully explicate his theory of biological inheritance, Galton abandoned this line of inquiry by the end of that decade and refocused his efforts on identifying statistical laws of heredity of individual differences (Renwick, 2011 ).

Historians generally agree that Galton was the first to treat nature (as heredity) and nurture (everything else) as separate causal forces (Keller, 2010 ), but the schism gained biological legitimacy through the work of the German cytologist Auguste Weismann in the 1880s. Whereas Galton’s theory was motivated by his political agenda, Weismann was motivated by a scientific, theoretical agenda. Namely, Weismann opposed Lamarckian inheritance and promoted a view of evolution driven almost entirely by natural selection.

Drawing upon contemporary cytological and embryological research, Weismann made the case that the determinative substances found in the germ cells of plants and animals (called the “germ-plasm”) that are transmitted across generations were physically sequestered very early in embryogenesis and remained buffered from the other cells of the body (“somato-plasm”). This so-called, Weismann’s barrier meant that alterations in the soma that develop in the lifetime of the organism through the use or disuse of body parts would not affect the germinal substances transmitted during reproduction (see Winther, 2001 , for review). On this view, Lamarckian-style inheritance of acquired characteristics was not biologically possible.

Galton and Weismann’s influence on the life sciences cannot be overstated. Their work convinced many to draw unusually sharp distinctions between the inherited (nature) and the acquired (nurture). Although their theories were met with much resistance and generated significant tension in the life sciences from cytology to psychology, their efforts helped stage a new epistemic space through which to appreciate Mendel’s soon to be rediscovered breeding studies and usher in genetics (Muller-Wille & Rheinberger, 2012 ).

Ever since, psychology has teetered between nature-biased and nurture-biased positions. With the rise of genetics, the wedge between nature–nurture was deepened in the early to mid- 20th century , creating fields of study that focused exclusively on the effects of either nature or nurture.

The “Middle Ground” Perspective on Nature–Nurture

Twenty-first-century psychology textbooks often state that the nature–nurture debates have been resolved, and the tension relaxed, because we have moved on from emphasizing nature or nurture to appreciating that development necessarily involves both nature and nurture. In this middle-ground position, one asks how nature and nurture interact. For example, how do biological (or genetic) predispositions for behaviors or innate knowledge bias early learning experiences? Or how might environmental factors influence the biologically determined (maturational) unfolding of bodily form and behaviors?

Rejection of the Nature–Nurture Divide

For some, the “middle-ground” resolution is as problematic as “either/or” views and does not resolve a deeper source of tension inherent in the dichotomy. On this view, the nature–nurture divide is neither a legitimate nor a constructive way of thinking about development. Instead, developmental analysis reveals that the terms commonly associated with nature (e.g., innate, genetic, hereditary, or instinctual) and nurture (environmental or learned) are so entwined and confounded (and often arbitrary) that their independent effects cannot be meaningfully discussed. The nature–nurture division oversimplifies developmental processes, takes too much for granted, and ultimately hinders scientific progress. Thus not only is there a lingering tension about how to balance the effects of nature and nurture in the middle-ground view, but there is also a growing tension to move beyond the dichotomous nature–nurture framework.

Nativism in Behavior: Instincts

Definitions of instinct can vary tremendously, but many contrast (a) instinct with reason (or intellect, thought, will), which is related to but separable from contrasting (b) instinct with learning (or experience or habit).

Instinct in the Age of Enlightenment

Early usages of the instinct concept, following Aristotle, treated instinct as a mental, estimative faculty ( vis aestimativa or aestimativa naturalis ) in humans and animals that allowed for the judgments of objects in the world (e.g., seeing a predator) to be deemed beneficial or harmful in a way that transcends immediate sensory experience but does not involve the use of reason (Diamond, 1971 ). In many of the early usages, the “natural instinct” of animals even included subrational forms of learning.

The modern usage of instincts as unlearned behaviors took shape in the 17th century . By that point it was widely believed that nature or God had implanted in animals and humans innate behaviors and predispositions (“instincts”) to promote the survival of the individual and the propagation of the species. Disagreements arose as to whether instincts derived from innate mental images or were mindlessly and mechanically (physiologically) generated from innately specified bodily organization (Richards, 1987 ).

Anti-Instinct Movement in the Age of Enlightenment

Challenges to the instinct concept can be found in the 16th century (see Diamond, 1971 ), but they were most fully developed by empiricist philosophers of the French Sensationalist tradition in the 18th century (Richards, 1987 ). Sensationalists asserted that animals behaved rationally and all of the so-called instincts displayed by animals could be seen as intelligently acquired habits.

For Sensationalists, instincts, as traditionally understood, did not exist. Species-specificity in behavior patterns could be explained by commonalities in physiological organization, needs, and environmental conditions. Even those instinctual behaviors seen at birth (e.g., that newly hatched chicks peck and eat grain) might eventually be explained by the animal’s prenatal experiences. Erasmus Darwin ( 1731–1802 ), for example, speculated that the movements and swallowing experiences in ovo could account for the pecking and eating of grain by young chicks. The anti-instinct sentiment was clearly expressed by the Sensationalist Jean Antoine Guer ( 1713–1764 ), who warned that instinct was an “infantile idea” that could only be held by those who are ignorant of philosophy, that traditional appeals to instincts in animals not only explained nothing but served to hinder scientific explanations, and that nothing could be more superficial than to explain behavior than appealing to so-called instincts (Richards, 1987 ).

The traditional instinct concept survived. For most people, the complex, adaptive, species-specific behaviors displayed by naïve animals (e.g., caterpillars building cocoons; infant suckling behaviors) appeared to be predetermined and unlearned. Arguably as important, however, was the resistance to the theological implications of Sensationalist philosophy.

One of the strongest reactions to Sensationalism was put forward in Germany by Herman Samuel Reimarus ( 1694–1768 ). As a natural theologian, Reimarus, sought evidence of a God in the natural world, and the species-specific, complex, and adaptive instincts of animals seemed to stand as the best evidence of God’s work. More so than any other, Reimarus extensively catalogued instincts in humans and animals. Rather than treat instincts as behaviors, he defined instincts as natural impulses (inner drives) to act that were expressed perfectly, without reflection or practice, and served adaptive goals (Richards, 1987 ). He even proposed instincts for learning, a proposal that would resurface in the mid- 20th century , as would his drive theory of instinct (Jaynes & Woodward, 1974 ).

Partly as a result of Reimarus’ efforts, the instinct concept survived going into the 19th century . But many issues surrounding the instinct concept were left unsettled. How do instincts differ from reflexive behaviors? What role does learning play in the expression of instincts, if any? Do humans have more or fewer instincts than animals? These questions would persist well into the first decades of the 20th century and ultimately fuel another anti-instinct movement.

Instinct in the 19th Century

In the 19th century , the tension about the nature and nurture of instincts in the lifetime of animals led to debates about the nature and nurture of instincts across generations . These debates dealt with whether instincts should be viewed as “inherited habits” from previous generations or whether they result from the natural selection. Debating the relative roles of neo-Lamarckian use-inheritance versus neo-Darwinian natural selection in the transmutation of species became a significant source of tension in the latter half of the 19th century . Although the neo-Lamarckian notion of instincts as being inherited habits was rejected in the 20th century , it has resurged in recent years (e.g., see Robinson & Barron, 2017 ).

Darwinian evolutionary theory required drawing distinctions between native and acquired behaviors, and, perhaps more so than before, behaviors were categorized along a continuum from the purely instinctive (unlearned), to the partially instinctive (requiring some learning), to the purely learned. Still, it was widely assumed that a purely instinctive response would be modified by experience after its first occurrence. As a result, instinct and habit were very much entangled in the lifetime of the organism. The notion of instincts as fixed and unmodifiable would not be widely advanced until after the rise of Weismann’s germ-plasm theory in the late 19thcentury .

Given their importance in evolutionary theory, there was greater interest in more objectively identifying pure instincts beyond anecdotal reports. Some of the most compelling evidence was reported by Douglas Spalding ( 1844–1877 ) in the early 1870s (see Gray, 1967 ). Spalding documented numerous instances of how naïve animals showed coordinated, seemingly adaptive responses (e.g., hiding) to objects (e.g., sight of predators) upon their first encounter, and he helped pioneer the use of the deprivation experiment to identify instinctive behaviors. This technique involved selectively depriving young animals of seemingly critical learning experiences or sensory stimulation. Should animals display some species-typical action following deprivation, then, presumably, the behavior could be labeled as unlearned or innate. In all, these studies seemed to show that animals displayed numerous adaptive responses at the very start, prior to any relevant experience. In a variety of ways, Spalding’s work anticipated 20th-century studies of innate behavior. Not only would the deprivation experiment be used as the primary means of detecting native tendencies by European zoologists and ethologists, but Spalding also showed evidence of what would later be called imprinting, critical period effects and evidence of behavioral maturation.

Reports of pure instinct did not go unchallenged. Lloyd Morgan ( 1896 ) questioned the accuracy of these reports in his own experimental work with young animals. In some cases, he failed to replicate the results and in other cases he found that instinctive behaviors were not as finely tuned to objects in the environment as had been claimed. Morgan’s research pointed to taking greater precision in identifying learned and instinctive components of behavior, but, like most at the turn of the 20th century , he did not question that animal behavior involved both learned and instinctive elements.

A focus on instinctive behaviors intensified in the 1890s as Weismann’s germ-plasm theory grew in popularity. More so than before, a sharp distinction was drawn between native and acquired characteristics, including behavior (Johnston, 1995 ). Although some psychologists continued to maintain neo-Lamarckian notions, most German (Burnham, 1972 ) and American (Cravens & Burnham, 1971 ) psychologists were quick to adopt Weismann’s theory. They envisioned a new natural science of psychology that would experimentally identify the germinally determined, invariable set of native psychological traits in species and their underlying physiological (neural) basis. However, whereas English-speaking psychologists tended to focus on how this view impacted our understanding of social institutions and its social implications, German psychologists were more interested in the longstanding philosophical implications of Weismann’s doctrine as it related to the differences (if any) between man and beast (Burnham, 1972 ).

Some anthropologists and sociologists, however, interpreted Weismann’s theory quite differently and used it elevate sociology as its own scientific discipline. In the 1890s, the French sociologist Emil Durkheim, for example, interpreted Weismann’s germinal determinants as a generic force on human behavior that influenced the development of general predispositions that are molded by the circumstances of life (Meloni, 2016 ). American anthropologists reached similar conclusions in the early 20th century (Cravens & Burnham, 1971 ). Because Weismann’s theory divorced biological inheritance from social inheritance, and because heredity was treated as a generic force, sociologists felt free to study social (eventually, “cultural”) phenomena without reference to biological or psychological concerns.

Anti-Instinct Movement in the 1920s

Despite their differences, in the first two decades of the 20th century both psychologists and sociologists generally assumed that humans and animals had some native tendencies or instincts. Concerns were even voiced that instinct had not received enough attention in psychology. Disagreements about instincts continued to focus on (the now centuries old debates of) how to conceptualize them. Were they complex reflexes, impulses, or motives to act, or should instinct be a mental faculty (like intuition), separate from reasoning and reflex (Herrnstein, 1972 )?

In America, the instinct concept came under fire following a brief paper in 1919 by Knight Dunlap titled “Are There Any Instincts?” His primary concern dealt with teleological definitions of instincts in which an instinct referred to all the activities involved in obtaining some end-state (e.g., instincts of crying, playing, feeding, reproduction, war, curiosity, or pugnacity). Defined in this way, human instincts were simply labels for human activities, but how these activities were defined was arbitrarily imposed by the researchers. Is feeding, for instance, an instinct, or is it composed of more basic instincts (like chewing and swallowing)? The arbitrariness of classifying human behavior had led to tremendous inconsistencies and confusion among psychologists.

Not all of the challenges to instinct dealt with its teleological usage. Some of the strongest criticisms were voiced by Zing-Yang Kuo throughout the 1920s. Kuo was a Chinese animal psychologist who studied under Charles Tolman at the University of California, Berkeley. Although Kuo’s attacks on instinct changed throughout the 1920s (see Honeycutt, 2011 ), he ultimately argued that all behaviors develop in experience-dependent ways and that appeals to instinct were statements of ignorance about how behaviors develop. Like Dunlap, he warned that instincts were labels with no explanatory value. To illustrate, after returning to China, he showed how the so-called rodent-killing instinct in cats often cited by instinct theorists is not found in kittens that are reared with rodents (Kuo, 1930 ). These kittens, instead, became attached to the rodents, and they resisted attempts to train rodent-killing. Echoing the point made by Guer, Kuo claimed that appeals to instinct served to stunt scientific inquiry into the developmental origins of behavior.

But Kuo did not just challenge the instinct concept. He also argued against labeling behaviors as “learned.” After all, whether an animal “learns” depends on the surrounding environmental conditions, the physiological and developmental status of the animal, and, especially, the developmental (or experiential) history of that animal. Understanding learning also required developmental analysis. Thus Kuo targeted the basic distinction between nature and nurture, and he was not alone in doing so (e.g., see Carmichael, 1925 ), but his call to reject it did not spread to mainstream American psychologists.

By the 1930s, the term instinct had fallen into disrepute in psychology, but experimental psychologists (including behaviorists) remained committed to a separation of native from acquired traits. If anything, the dividing line between native and acquired behaviors became more sharply drawn than before (Logan & Johnston, 2007 ). For some psychologists, instinct was simply rebranded in the less contentious (but still problematic) language of biological drives or motives (Herrnstein, 1972 ). Many other psychologists simply turned to describing native traits as due to “maturation” and/or “heredity” rather than “instinct.”

Fixed Action Patterns

The hereditarian instinct concept received a reboot in Europe in the 1930s with the rise of ethology led by Konrad Lorenz, Niko Tinbergen, and others. Just as animals inherit organs that perform specific functions, ethologists believed animals inherit behaviors that evolved to serve adaptive functions as well. Instincts were described as unlearned (inherited), blind, stereotyped, adaptive, fixed action patterns, impervious to change that are initiated (released) by specific stimuli in the environment.

Ethologists in 1930s and 1940s were united under the banner of innateness. They were increasingly critical of the trend by American psychologists (i.e., behaviorists) to focus on studying on how a limited number of domesticated species (e.g., white rat) responded to training in artificial settings (Burkhardt, 2005 ). Ethologists instead began with rich descriptions of animal behavior in more natural environments along with detailed analyses of the stimulus conditions that released the fixed action patterns. To test whether behavioral components were innate, ethologists relied primarily on the deprivation experiment popularized by Spalding in the 19th century . Using these methods (and others), ethologists identified numerous fascinating examples of instinctive behaviors, which captured mainstream attention.

In the early 1950s, shortly after ethology had gained professional status (Burkhardt, 2005 ), a series of challenges regarding instinct and innateness were put forth by a small cadre of North American behavioral scientists (e.g., T. C. Schneirla, Donald Hebb, Frank Beach). Arguably the most influential critique was voiced by comparative psychologist Daniel Lehrman ( 1953 ), who presented a detailed and damning critique of deprivation experiments on empirical and logical grounds. Lehrman explained that deprivation experiments isolate the animal from some but not all experiences. Thus deprivation experiments simply change what an animal experiences rather than eliminating experience altogether, and so they cannot possibly determine whether a behavior is innate (independent of experience). Instead, these experiments show what environmental conditions do not matter in the development of a behavior but do not speak to what conditions do matter .

Lehrman went on to argue that the whole endeavor to identify instinctive or innate behavior was misguided from the start. All behavior, according to Lehrman, develops from a history of interactions between an organism and its environment. If a behavior is found to develop in the absence of certain experiences, the researcher should not stop and label it as innate. Rather, research should continue to identify the conditions under which the behavior comes about. In line with Kuo, Lehrman repeated the warning that to label something as instinctive (or inherited or maturational) is a statement of ignorance about how that behavior develops and does more to stunt than promote research.

Lehrman’s critique created significant turmoil among ethologists. As a result, ethologists took greater care in using the term innate , and it led to new attempts to synthesize or re-envision learning and instinct .

Some of these attempts focused on an increased role for learning and experience in the ontogeny of species-typical behaviors. These efforts spawned significant cross-talk between ethologists and comparative psychologists to more thoroughly investigate behavioral development under natural conditions. Traditional appeals to instinct and learning (as classical and operant conditioning) were both found to be inadequate for explaining animal behavior. In their stead, these researchers focused more closely on how anatomical, physiological, experiential, and environmental conditions influenced the development of species-typical behaviors.

Tinbergen ( 1963 ) was among those ethologists who urged for greater developmental analysis of species-typical behaviors, and he included it as one of his four problems in the biological study of organisms, along with causation (mechanism), survival value (function), and evolution. Of these four problems, Tinbergen believed ethologists were especially well suited to study survival value, which he felt had been seriously neglected (Burkhardt, 2005 ).

The questions of survival value coupled with models of population genetics would gain significant momentum in the 1960s and 1970s in England and the United States with the rise of behavioral ecology and sociobiology (Griffiths, 2008 ). But because these new fields seemed to promote some kind of genetic determinism in behavioral development, they were met with much resistance and reignited a new round of nature–nurture debates in the 1970s (see Segerstrale, 2000 ).

However, not all ethologists abandoned the instinct concept. Lorenz, in particular, continued to defend the division between nature and nurture. Rather than speaking of native and acquired behaviors, Lorenz later spoke of two different sources of information for behavior (innate/genetic vs. acquired/environmental), which was more a subtle shift in language than it was an actual change in theory, as Lehrman later pointed out.

Some ethologists followed Lorenz’s lead and continued to maintain more of a traditional delineation between instinct and learning. Their alternative synthesis viewed learning as instinctive (Gould & Marler, 1987 ). They proposed that animals have evolved domain-specific “instincts to learn” that result from the its genetic predispositions and innate knowledge. To support the idea of instincts for learning, ethologists pointed to traditional ethological findings (on imprinting and birdsong learning), but they also drew from the growing body of work in experimental psychology that seemed to indicate certain types of biological effects on learning.

Biological Constraints and Preparedness

While ethology was spreading in Europe in the 1930s–1950s, behaviorism reigned in the United States. Just as ethologists were confronted with including a greater role of nurture in their studies, behaviorists were challenged to consider a greater role of nature.

Behaviorists assumed there to be some behavioral innateness (e.g., fixed action patterns, unconditioned reflexes, primary reinforcers and drives). But because behaviorists focused on learning, they tended to study animals in laboratory settings using biologically (or ecologically) irrelevant stimuli and responses to minimize any role of instinct (Johnston, 1981 ). It was widely assumed that these studies would identify general laws of learning that applied to all species regardless of the specific cues, reinforcers, and responses involved.

Challenges to the generality assumption began to accumulate in the 1960s. Some studies pointed to failures that occurred during conditioning procedures. Breland and Breland ( 1961 ), for example, reported that some complex behaviors formed through operant conditioning would eventually become “displaced” by conditioned fixed action patterns in a phenomenon they called “instinctive drift.” Studies of taste-aversion learning (e.g., Garcia & Koelling, 1966 ) also reported the failure of rats to associate certain events (e.g., flavors with shock or audiovisual stimuli with toxicosis).

Other studies were pointing to enhanced learning. In particular, it was found that rats could form strong conditioned taste aversions after only a single pairing between a novel flavor and illness. (This rapid “one trial learning” was a major focus in the research from Niko Tinbergen’s ethological laboratory.) Animals, it seemed, had evolved innate predispositions to form (or not form) certain associations.

In humans, studies of biological constraints on learning were mostly limited to fear conditioning. Evidence indicated that humans conditioned differently to (biologically or evolutionarily) fear-relevant stimuli like pictures of spiders or snakes than to fear-irrelevant stimuli like pictures of mushrooms or flowers (Ohman, Fredrikson, Hugdahl, & Rimmö, 1976 ).

These findings and others were treated as a major problem in learning theory and led to calls for a new framework to study learning from a more biologically oriented perspective that integrated the evolutionary history and innate predispositions of the species. These predispositions were described as biological “constraints” on, “preparedness,” or “adaptive specializations” for learning, all of which were consistent with the “instincts to learn” framework proposed by ethologists.

By the 1980s it was becoming clear that the biological preparedness/constraint view of learning suffered some limitations. For example, what constraints count as “biological” was questioned. It was well established that there were general constraints on learning associated with the intensity, novelty, and timing of stimuli. But, arbitrarily it seemed, these constraints were not classified as “biological” (Domjan & Galef, 1983 ). Other studies of “biological constraints” found that 5- and 10-day old rats readily learned to associated a flavor with shock (unlike in adults), but (like in adults) such conditioning was not found in 15-day-old rats (Hoffman & Spear, 1988 ). In other words, the constraint on learning was not present in young rats but developed later in life, suggesting a possible role of experience in bringing about the adult-like pattern.

Attempts to synthesize these alternatives led to numerous calls for more ecologically oriented approaches to learning not unlike the synthesis between ethology and comparative psychology in the 1960s. All ecological approaches to learning proposed that learning should be studied in the context of “natural” (recurrent and species-typical) problems that animals encounter (and have evolved to encounter) using ecologically meaningful stimuli and responses. Some argued (e.g., Johnston, 1981 ) that studies of learning should take place within the larger context of studying how animals develop and adapt to their surround. Others (Domjan & Galef, 1983 ) pointed to more of a comparative approach in studying animal learning in line with behavioral ecology that takes into account how learning can be influenced by the possible selective pressures faced by each species. Still, how to synthesize biological constraints (and evolutionary explanations) on learning with a general process approach remains a source of tension in experimental psychology.

Nativism in Mind: Innate Ideas

Nativism and empiricism in philosophy.

In the philosophy of mind, nature–nurture debates are voiced as debates between nativists and empiricists. Nativism is a philosophical position that holds that our minds have some innate (a priori to experience) knowledge, concepts, or structure at the very start of life. Empiricism, in contrast, holds that all knowledge derives from our experiences in the world.

However, rarely (if ever) were there pure nativist or empiricist positions, but the positions bespeak a persistent tension. Empiricists tended to eschew innateness and promote a view of the mental content that is built by general mechanisms (e.g., association) operating on sensory experiences, whereas nativists tend to promote a view of mind that contains domain-specific, innate processes and/or content (Simpson, Carruthers, Laurence, & Stich, 2005 ). Although the tension about mental innateness would loosen as empiricism gained prominence in philosophy and science, the strain never went away and would intensify again in the 20th century .

Nativism in 20th Century Psychology: The Case of Language Development

In the first half of the 20th century , psychologists generally assumed that knowledge was gained or constructed through experience with the world. This is not to say that psychologists did not assume some innate knowledge. The Swiss psychologist Jean Piaget, for example, believed infants enter the world with some innate knowledge structures, particularly as they relate to early sensory and motor functioning (see Piaget, 1971 ). But the bulk of his work dealt with the construction of conceptual knowledge as children adapt to their worlds. By and large, there were no research programs in psychology that sought to identify innate factors in human knowledge and cognition until the 1950s (Samet & Zaitchick, 2017 )

An interest in psychological nativism was instigated in large part by Noam Chomsky’s ( 1959 ) critique of B. F. Skinner’s book on language. To explain the complexity of language, he argued, we must view language as the knowledge and application of grammatical rules. He went on to claim that the acquisition of these rules could not be attributed to any general-purpose, learning process (e.g., reinforcement). Indeed, language acquisition occurs despite very little explicit instruction. Moreover, language is special in terms of its complexity, ease, and speed of acquisition by children and in its uniqueness to humans. Instead, he claimed that our minds innately contain some language-specific knowledge that kick-starts and promotes language acquisition. He later claimed this knowledge can be considered some sort of specialized mental faculty or module he called the “language acquisition device” (Chomsky, 1965 ) or what Pinker ( 1995 ) later called the “language instinct.”

To support the idea of linguistic nativism, Chomsky and others appealed to the poverty of the stimulus argument. In short, this argument holds that our experiences in life are insufficient to explain our knowledge and abilities. When applied to language acquisition, this argument holds children’s knowledge of language (grammar) goes far beyond the limited, and sometimes broken, linguistic events that children directly encounter. Additional evidence for nativism drew upon the apparent maturational quality of language development. Despite wide variations in languages and child-rearing practices across the world, the major milestones in language development appear to unfold in children in a universal sequence and timeline, and some evidence suggested a critical period for language acquisition.

Nativist claims about language sparked intense rebuttals by empiricist-minded psychologists and philosophers. Some of these retorts tackled the logical limitations of the poverty of stimulus argument. Others pointed to the importance of learning and social interaction in driving language development, and still others showed that language (grammatical knowledge) may not be uniquely human (see Tomasello, 1995 , for review). Nativists, in due course, provided their own rebuttals to these challenges, creating a persistent tension in psychology.

Extending Nativism Beyond Language Development

In the decades that followed, nativist arguments expanded beyond language to include cognitive domains that dealt with understanding the physical, psychological, and social worlds. Developmental psychologists were finding that infants appeared to be much more knowledgeable in cognitive tasks (e.g., on understanding object permanence) and skillful (e.g., in imitating others) than had previously been thought, and at much younger ages. Infants also showed a variety of perceptual biases (e.g., preference for face-like stimuli over equally complex non-face-like stimuli) from very early on. Following the standard poverty of the stimulus argument, these findings were taken as evidence that infants enter the world with some sort of primitive, innate, representational knowledge (or domain-specific neural mechanisms) that constrains and promotes subsequent cognitive development. The nature of this knowledge (e.g., as theories or as core knowledge), however, continues to be debated (Spelke & Kinzler, 2007 ).

Empiricist-minded developmental psychologists responded by demonstrating shortcomings in the research used to support nativist claims. For example, in studies of infants’ object knowledge, the behavior of infants (looking time) in nativist studies could be attributed to relatively simple perceptual processes rather than to the infants’ conceptual knowledge (Heyes, 2014 ). Likewise, reports of human neonatal imitation not only suffered from failures to replicate but could be explained by simpler mechanisms (e.g., arousal) than true imitation (Jones, 2017 ). Finally, studies of perceptual preferences found in young infants, like newborn preferences for face-like stimuli, may not be specific preferences for faces per se but instead may reflect simpler, nonspecific perceptual biases (e.g., preferences for top-heavy visual configurations and congruency; Simion & Di Giorgio, 2015 ).

Other arguments from empiricist-minded developmental psychologists focused on the larger rationale for inferring innateness. Even if it is conceded that young infants, like two-month-olds, or even two-day-olds, display signs of conceptual knowledge, there is no good evidence to presume the knowledge is innate. Their knowledgeable behaviors could still be seen as resulting from their experiences (many of which may be nonobvious to researchers) leading up to the age of testing (Spencer et al., 2009 ).

In the 21st century , there is still no consensus about the reality, extensiveness, or quality of mental innateness. If there is innate knowledge, can experience add new knowledge or only expand the initial knowledge? Can the doctrine of innate knowledge be falsified? There are no agreed-upon answers to these questions. The recurring arguments for and against mental nativism continue to confound developmental psychologists.

Maturation Theory

The emergence of bodily changes and basic behavioral skills sometimes occurs in an invariant, predictable, and orderly sequence in a species despite wide variations in rearing conditions. These observations are often attributed to the operation of an inferred, internally driven, maturational process. Indeed, 21st-century textbooks in psychology commonly associate “nature” with “maturation,” where maturation is defined as the predetermined unfolding of the individual from a biological or genetic blueprint. Environmental factors play a necessary, but fundamentally supportive, role in the unfolding of form.

Preformationism Versus Epigenesis in the Generation of Form

The embryological generation of bodily form was debated in antiquity but received renewed interest in the 17th century . Following Aristotle, some claimed that embryological development involved “epigenesis,” defined as the successive emergence of form from a formless state. Epigenesists, however, struggled to explain what orchestrated development without appealing to Aristotelean souls. Attempts were made to invoke to natural causes like physical and chemical forces, but, despite their best efforts, the epigenesists were forced to appeal to the power of presumed, quasi-mystical, vitalistic forces (entelechies) that directed development.

The primary alternative to epigenesis was “preformationism,” which held that development involved the growth of pre-existing form from a tiny miniature (homunculus) that formed immediately after conception or was preformed in the egg or sperm. Although it seems reasonable to guess that the invention and widespread use of the microscope would immediately lay to rest any claim of homuncular preformationism, this was not the case. To the contrary, some early microscopists claimed to see signs of miniature organisms in sperm or eggs, and failures to find these miniatures were explained away (e.g., the homunculus was transparent or deflated to the point of being unrecognizable). But as microscopes improved and more detailed observations of embryological development were reported in the late 18th and 19th centuries , homuncular preformationism was finally refuted.

From Preformationism to Predeterminism

Despite the rejection of homuncular preformationism, preformationist appeals can be found throughout the 19th century . One of the most popular preformationist theories of embryological development was put forth by Ernst Haeckel in the 1860s (Gottlieb, 1992 ). He promoted a recapitulation theory (not original to Haeckel) that maintained that the development of the individual embryo passes through all the ancestral forms of its species. Ontogeny was thought to be a rapid, condensed replay of phylogeny. Indeed, for Haeckel, phylogenesis was the mechanical cause of ontogenesis. The phylogenetic evolution of the species created the maturational unfolding of embryonic form. Exactly how this unfolding takes place was less important than its phylogenetic basis.

Most embryologists were not impressed with recapitulation theory. After all, the great embryologist Karl Ernst von Baer ( 1792–1876 ) had refuted strict recapitulation decades earlier. Instead, there was greater interest in how best to explain the mechanical causes of development ushering in a new “experimental embryology.” Many experimental embryologists followed the earlier epigenesists by discussing vitalistic forces operating on the unorganized zygote. But it soon became clear that the zygote was structured, and many people believed the zygote contained special (unknown) substances that specified development. Epigenesis-minded experimental embryologists soon warned that the old homuncular preformationism was being transformed into a new predetermined preformationism.

As a result, the debates between preformationism and epigenesis were reignited in experimental embryology, but the focus of these debates shifted to the various roles of nature and nurture during development. More specifically, research focused on the extent to which early cellular differentiation was predetermined by factors internal to cells like chromosomes or cytoplasm (preformationism, nature) or involved factors (e.g., location) outside of the cell (epigenesis, nurture). The former emphasized reductionism and developmental programming, whereas the latter emphasized some sort of holistic, regulatory system responsive to internal and external conditions. The tension between viewing development as predetermined or “epigenetic” persists into the 21st century .

Preformationism gained momentum in the 20th century following the rediscovery of Mendel’s studies of heredity and the rapid rise of genetics, but not because of embryological research on the causes of early differentiation. Instead, preformationism prevailed because it seemed embryological research on the mechanisms of development could be ignored in studies of hereditary patterns.

The initial split between heredity and development can be found in Galton’s speculations but is usually attributed to Weismann’s germ-plasm theory. Weismann’s barrier seemed to posit that the germinal determinants present at conception would be the same, unaltered determinants transmitted during reproduction. This position, later dubbed as “Weismannism,” was ironically not one promoted by Weismann. Like nearly all theorists in the 19th century , he viewed the origins of variation and heredity as developmental phenomena (Amundson, 2005 ), and he claimed that the germ-plasm could be directly modified in the lifetime of the organism by environmental (e.g., climactic and dietary) conditions (Winther, 2001 ). Still, Weismann’s theory treated development as a largely predetermined affair driven by inherited, germinal determinants buffered from most developmental events. As such, it helped set the stage for a more formal divorce between heredity and development with the rise of Mendelism in the early 20th century .

Mendel’s theory of heredity was exceptional in how it split development from heredity (Amundson, 2005 ). More so than in Weismann’s theory, Mendel’s theory assumed that the internal factors that determine form and are transmitted across generations remain unaltered in the lifetime of the organism. To predict offspring outcomes, one need only know the combination of internal factors present at conception and their dominance relations. Exactly how these internal factors determined form could be disregarded. The laws of hereditary transmission of the internal factors (e.g., segregation) did not depend on the development or experiences of the organism or the experiences the organism’s ancestors. Thus the experimental study of heredity (i.e., breeding) could proceed without reference to ancestral records or embryological concerns (Amundson, 2000 ). By the mid-1920s, the Mendelian factors (now commonly called “genes”) were found to be structurally arranged on chromosomes, and the empirical study of heredity (transmission genetics) was officially divorced from studies of development.

The splitting of heredity and development found in Mendel’s and Weismann’s work met with much resistance. Neo-Lamarckian scientists, especially in the United States (Cook, 1999 ) and France (Loison, 2011 ), sought unsuccessfully to experimentally demonstrate the inheritance of acquired characteristics into the 1930s.

In Germany during the 1920s and 1930s, resistance to Mendelism dealt with the chromosomal view of Mendelian heredity championed by American geneticists who were narrowly focused on studying transmission genetics at the expense of developmental genetics. German biologists, in contrast, were much more interested in the broader roles of genes in development (and evolution). In trying to understand how genes influence development, particularly of traits of interest to embryologists, they found the Mendelian theory to be lacking. In the decades between the world wars, German biologists proposed various expanded views of heredity that included some form of cytoplasmic inheritance (Harwood, 1985 ).

Embryologists resisted the preformationist view of development throughout the early to mid- 20th century , often maintaining no divide between heredity and development, but their objections were overshadowed by genetics and its eventual synthesis with evolutionary theory. Consequently, embryological development was treated by geneticists and evolutionary biologists as a predetermined, maturational process driven by internal, “genetic” factors buffered from environmental influence.

Maturation Theory in Psychology

Maturation theory was applied to behavioral development in the 19th century in the application of Haeckel’s recapitulation theory. Some psychologists believed that the mental growth of children recapitulated the history of the human race (from savage brute to civilized human). With this in mind, many people began to more carefully document child development. Recapitulationist notions were found in the ideas of many notable psychologists in the 19th and early 20th centuries (e.g., G. S. Hall), and, as such, the concept played an important role in the origins of developmental psychology (Koops, 2015 ). But for present purposes what is most important is that children’s mental and behavioral development was thought to unfold via a predetermined, maturational process.

With the growth of genetics, maturational explanations were increasingly invoked to explain nearly all native and hereditary traits. As the instinct concept lost value in the 1920s, maturation theory gained currency, although the shift was largely a matter of semantics. For many psychologists, the language simply shifted from “instinct versus learning” to “maturation versus practice/experience” (Witty & Lehman, 1933 ).

Initial lines of evidence for maturational explanations of behavior were often the same as those that justified instinct and native traits, but new embryological research presented in the mid-1920s converged to show support for strict maturational explanations of behavioral development. In these experiments (see Wyman, 2005 , for review), spanning multiple laboratories, amphibians (salamanders and frogs) were exposed to drugs that acted as anesthetics and/or paralytics throughout the early stages of development, thus reducing sensory experience and/or motor practice. Despite the reduced sensory experiences and being unable to move, these animals showed no delays in the onset of motor development once the drugs wore off.

This maturational account of motor development in amphibians fit well with contemporaneous studies of motor development in humans. The orderly, invariant, and predictable (age-related) sequential appearance of motor skills documented in infants reared under different circumstances (in different countries and across different decades) was seen as strong evidence for a maturational account. Additional evidence was reported by Arnold Gessell and Myrtle McGraw, who independently presented evidence in the 1920s to show that the pace and sequence of motor development in infancy were not altered by special training experiences. Although the theories of these maturation theorists were more sophisticated when applied to cognitive development, their work promoted a view in which development was primarily driven by neural maturation rather than experience (Thelen, 2000 ).

Critical and Sensitive Periods

As the maturation account of behavioral development gained ground, it became clear that environmental input played a more informative role than had previously been thought. Environmental factors were found to either disrupt or induce maturational changes at specific times during development. Embryological research suggested that there were well-delineated time periods of heightened sensitivity in which specific experimental manipulations (e.g., tissue transplantations) could induce irreversible developmental changes, but the same manipulation would have no effect outside of that critical period.

In the 1950s–1960s a flurry of critical period effects were reported in birds and mammals across a range of behaviors including imprinting, attachment, socialization, sensory development, bird song learning, and language development (Michel & Tyler, 2005 ). Even though these findings highlighted an important role of experience in behavioral development, evidence of critical periods was usually taken to imply some rigid form of biological determinism (Oyama, 1979 ).

As additional studies were conducted on critical period effects, it became clear that many of the reported effects were more gradual, variable, experience-dependent, and not necessarily as reversible as was previously assumed. In light of these reports, there was a push in the 1970s (e.g., Connolly, 1972 ) to substitute “sensitive period” for “critical period” to avoid the predeterminist connotations associated with the latter and to better appreciate that these periods simply describe (not explain) certain temporal aspects of behavioral development. As a result, a consensus emerged that behaviors should not be attributed to “time” or “age” but to the developmental history and status of the animal under investigation (Michel & Tyler, 2005 ).

Heredity and Genetics

In the decades leading up to and following the start of the 20th century , it was widely assumed that many psychological traits (not just instincts) were inherited or “due to heredity,” although the underlying mechanisms were unknown. Differences in intelligence, personality, and criminality within and between races and sexes were largely assumed to be hereditary and unalterable by environmental intervention (Gould, 1996 ). The evidence to support these views in humans was often derived from statistical analyses of how various traits tended to run in families. But all too frequently, explanations of data were clouded by pre-existing, hereditarian assumptions.

Human Behavioral Genetics

The statistical study of inherited human (physical, mental, and behavioral) differences was pioneered by Galton ( 1869 ). Although at times Galton wrote that nature and nurture were so intertwined as to be inseparable, he nevertheless devised statistical methods to separate their effects. In the 1860s and 1870s, Galton published reports purporting to show how similarities in intellect (genius, talent, character, and eminence) in European lineages appeared to be a function of degree of relatedness. Galton considered, but dismissed, environmental explanations of his data, leading him to confirm his belief that nature was stronger than nurture.

Galton also introduced the use of twin studies to tease apart the relative impact of nature versus nurture, but the twin method he used was markedly different from later twin studies used by behavioral geneticists. Galton tracked the life history of twins who were judged to be very similar or very dissimilar near birth (i.e., by nature) to test the power of various postnatal environments (nurture) that might make them more or less similar over time. Here again, Galton concluded that nature overpowers nurture.

Similar pedigree (e.g., the Kallikak study; see Zenderland, 2001 ) and twin studies appeared in the early 1900s, but the first adoption study and the modern twin method (which compares monozygotic to dizygotic twin pairs) did not appear until the 1920s (Rende, Plomin, & Vandenberg, 1990 ). These reports led to a flurry of additional work on the inheritance of mental and behavioral traits over the next decade.

Behavioral genetic research peaked in the 1930s but rapidly lost prominence due in large part to its association with the eugenics movement (spearheaded by Galton) but also because of the rise and eventual hegemony of behaviorism and the social sciences in the United States. Behavioral genetics resurged in the 1960s with the rising tide of nativism in psychology, and returned to its 1930s-level prominence in the 1970s (McGue & Gottesman, 2015 ).

The resurgence brought with a new statistical tool: the heritability statistic. The origins of heritability trace back to early attempts to synthesize Mendelian genetics with biometrics by Ronald Fisher and others. This synthesis ushered in a new field of quantitative genetics and it marked a new way of thinking about nature and nurture. The shift was to no longer think about nature and nurture as causes of traits in individuals but as causes of variation in traits between populations of individuals. Eventually, heritability came to refer to the amount of variance in a population sample that could be statistically attributed to genetic variation in that sample. Kinship (especially twin) studies provided seemingly straightforward ways of partitioning variation in population trait attributes into genetic versus environmental sources.

Into the early 21st century , hundreds of behavioral genetic studies of personality, intelligence, and psychopathology were reported. With rare exceptions, these studies converge to argue for a pervasive influence of genetics on human psychological variation.

These studies have also fueled much controversy. Citing in part behavioral genetic research, the educational psychologist Arthur Jensen ( 1969 ) claimed that the differences in intelligence and educational achievement in the United States between black and white students appeared to have a strong genetic basis. He went on to assume that because these racial differences appeared hereditary, they were likely impervious to environmental (educational) intervention. His article fanned the embers of past eugenics practices and ignited fiery responses (e.g., Hirsch, 1975 ). The ensuing debates not only spawned a rethinking of intelligence and how to measure it, but they ushered in a more critical look at the methods and assumptions of behavioral genetics.

Challenges to Behavioral Genetics

Many of the early critiques of behavioral genetics centered on interpreting the heritability statistic commonly calculated in kinship (family, twin, and adoption) studies. Perhaps more so than any other statistic, heritability has been persistently misinterpreted by academics and laypersons alike (Lerner, 2002 ). Contrary to popular belief, heritability tells us nothing about the relative impact of genetic and environmental factors on the development of traits in individuals. It deals with accounting for trait variation between people, not the causes of traits within people. As a result, a high heritability does not indicate anything about the fixity of traits or their imperviousness to environmental influence (contra Jensen), and a low heritability does not indicate an absence of genetic influence on trait development. Worse still, heritability does not even indicate anything about the role of genetics in generating the differences between people.

Other challenges to heritability focused not on its interpretation but on its underlying computational assumptions. Most notably, heritability analyses assume that genetic and environmental contributions to trait differences are independent and additive. The interaction between genetic and environmental factors were dismissed a priori in these analyses. Studies of development, however, show that no factor (genes, hormones, parenting, schooling) operates independently, making it impossible to quantify how much of a given trait in a person is due to any causal factor. Thus heritability analyses are bound to be misleading because they are based on biologically implausible and logically indefensible assumptions about development (Gottlieb, 2003 ).

Aside from heritability, kinship studies have been criticized for not being able to disentangle genetic and environmental effects on variation. It had long been known that that in family (pedigree) studies, environmental and genetic factors are confounded. Twin and adoption studies seemed to provide unique opportunities to statistically disentangle these effects, but these studies are also deeply problematic in assumptions and methodology. There are numerous plausible environmental reasons for why monozygotic twin pairs could resemble each other more than dizygotic twin pairs or why adoptive children might more closely resemble their biological than their adoptive parents (Joseph & Ratner, 2013 ).

A more recent challenge to behavioral genetics came from an unlikely source. Advances in genomic scanning in the 21st century made it possible in a single study to correlate thousands of genetic polymorphisms with variation in the psychological profiles (e.g., intelligence, memory, temperament, psychopathology) of thousands of people. These “genome-wide association” studies seemed to have the power and precision to finally identify genetic contributions to heritability at the level of single nucleotides. Yet, these studies consistently found only very small effects.

The failure to find large effects came to be known as the “missing heritability” problem (Maher, 2008 ). To account for the missing heritability, some behavioral geneticists and molecular biologists asserted that important genetic polymorphisms remain unknown, they may be too rare to detect, and/or that current studies are just not well equipped to handle gene–gene interactions. These studies were also insensitive to epigenetic profiles (see the section on Behavioral Epigenetics), which deal with differences in gene expression. Even when people share genes, they may differ in whether those genes get expressed in their lifetimes.

But genome-wide association studies faced an even more problematic issue: Many of these studies failed to replicate (Lickliter & Honeycutt, 2015 ). For those who viewed heritability analyses as biologically implausible, the small effect sizes and failures to replicate in genome-wide association studies were not that surprising. The search for independent genetic effects was bound to fail, because genes simply do not operate independently during development.

Behavioral Epigenetics

Epigenetics was a term coined in the 1940s by the developmental biologist Conrad Waddington to refer to a new field of study that would examine how genetic factors interact with local environmental conditions to bring about the embryological development of traits. By the end of the 20th century , epigenetics came to refer to the study of how nongenetic, molecular mechanisms physically regulate gene expression patterns in cells and across cell lineages. The most-studied mechanisms involve organic compounds (e.g., methyl-groups) that physically bind to DNA or the surrounding proteins that package DNA. The addition or removal of these compounds can activate or silence gene transcription. Different cell types have different, stable epigenetic markings, and these markings are recreated during cell division so that cells so marked give rise to similar types of cells. Epigenetic changes were known to occur during developmental periods of cellular differentiation (e.g., during embryogenesis), but not until 2004 was it discovered that these changes can occur at other periods in the life, including after birth (Roth, 2013 )

Of interest to psychologists were reports that different behavioral and physiological profiles (e.g., stress reactivity) of animals were associated with different epigenetic patterns in the nervous system (Moore, 2015 ). Furthermore, these different epigenetic patterns could be established or modified by environmental factors (e.g., caregiving practices, training regimes, or environmental enrichment), and, under certain conditions, they remain stable over long periods of time (from infancy to adulthood).

Because epigenetic research investigates the physical interface between genes and environment, it represents an exciting advance in understanding the interaction of nature and nurture. Despite some warnings that the excitement over behavioral epigenetic research may be premature (e.g., Miller, 2010 ), for many psychologists, epigenetics underscores how development involves both nature and nurture.

For others, what is equally exciting is the additional evidence epigenetics provides to show that the genome is an interactive and regulated system. Once viewed as the static director of development buffered from environment influence, the genome is better described as a developing resource of the cell (Moore, 2015 ). More broadly, epigenetics also points to how development is not a genetically (or biologically) predetermined affair. Instead, epigenetics provides additional evidence that development is a probabilistic process, contingent upon factors internal and external to the organism. In this sense, epigenetics is well positioned to help dissolve the nature–nurture dichotomy.

Beyond Nature–Nurture

In the final decades of the 20th century , a position was articulated to move beyond the dichotomous nature–nurture framework. The middle-ground position on nature–nurture did not seem up to the task of explaining the origins of form, and it brought about more confusion than clarity. The back-and-forth (or balanced) pendulum between nature- and nurture-based positions throughout history had only gone in circles. Moving forward would require moving beyond such dichotomous thinking (Johnston, 1987 ).

The anti-dichotomy position, referred to as the Developmentalist tradition, was expressed in a variety of systems-based, metatheoretical approaches to studying development, all of which extended the arguments against nature–nurture expressed earlier by Kuo and Lehrman. The central problem with all nativist claims according to Developmentalists is a reliance on preformationism (or predeterminism).

The problem with preformationism, they argue, besides issues of evidence, is that it is an anti-developmental mindset. It presumes the existence of the very thing(s) one wishes to explain and, consequently, discourages developmental analyses. To claim that some knowledge is innate effectively shuts down research on the developmental origins of that knowledge. After all, why look for the origins of conceptual knowledge if that knowledge is there all along? Or why search for any experiential contributions to innate behaviors if those behaviors by definition develop independently of experience? In the words of Developmentalists Thelen and Adolph ( 1992 ), nativism “leads to a static science, with no principles for understanding change or for confronting the ultimate challenge of development, the source of new forms in structure and function” (p. 378).

A commitment to maturational theory is likely one of the reasons why studies of motor development remained relatively dormant for decades following its heyday in the 1930–1940s (Thelen, 2000 ). Likewise, a commitment to maturational theory also helps explain the delay in neuroscience to examine how the brain physically changes in response to environmental conditions, a line of inquiry that only began in the 1960s.

In addition to the theoretical pitfalls of nativism, Developmentalists point to numerous studies that show how some seemingly native behaviors and innate constraints on learning are driven by the experiences of animals. For example, the comparative psychologist Gilbert Gottlieb ( 1971 ) showed that newly hatched ducklings display a naïve preference for a duck maternal call over a (similarly novel) chicken maternal call (Gottlieb, 1971 ), even when duck embryos were repeatedly exposed to the chicken call prior to hatching (Gottlieb, 1991 ). It would be easy to conclude that ducklings have an innate preference to approach their own species call and that they are biologically constrained (contraprepared) in learning a chicken call. However, Gottlieb found that the naïve preference for the duck call stemmed from exposure to the duck embryos’ own (or other) vocalizations in the days before hatching (Gottlieb, 1971 ). Exposure to these vocalizations not only made duck maternal calls more attractive, but it hindered the establishment of a preference for heterospecific calls. When duck embryos were reared in the absence of the embryonic vocalizations (by devocalizing embryos in ovo ) and exposed instead to chicken maternal calls, the newly hatched ducklings preferred chicken over duck calls (Gottlieb, 1991 ). These studies clearly showed how seemingly innate, biologically based preferences and constraints on learning derived from prenatal sensory experiences.

For Developmentalists, findings like these suggest that nativist explanations of any given behavior are statements of ignorance about how that behavior actually develops. As Kuo and Lehrman made clear, nativist terms are labels, not explanations. Although such appeals are couched in respectable, scientific language (e.g., “X is due to maturation, genes, or heredity”), they argue it would be more accurate simply to say that “We don’t know what causes X” or that “X is not due to A, B, or C.” Indeed, for Developmentalists, the more we unpack the complex dynamics about how traits develop, the less likely we are to use labels like nature or nurture (Blumberg, 2005 ).

On the other hand, Developmentalists recognize that labeling a behavior as “learned” also falls short as an explanatory construct. The empiricist position that knowledge or behavior is learned does not adequately take into account that what is learned and how easily something is learned depends on (a) the physiological and developmental status of the person, (b) the nature of the surrounding physical and social context in which learning takes place, and the (c) experiential history of the person. The empiricist tendency to say “X is learned or acquired through experience” can also short-circuit developmental analyses in the same way as nativist claims.

Still, Developmentalists appreciate that classifying behaviors can be useful. For example, the development of some behaviors may be more robust, reliably emerging across a range of environments and/or remaining relatively resistant to change, whereas others are more context-specific and malleable. Some preferences for stimuli require direct experience with those stimuli. Other preferences require less obvious (indirect) types of experiences. Likewise, it can still be useful to describe some behaviors in the ways shown in Table 1 . Developmentalists simply urge psychologists to resist the temptation to treat these behavioral classifications as implying different kinds of explanations (Johnston, 1987 ).

Rather than treat nature and nurture as separate developmental sources of causation (see Figure 1 ), Developmentalists argue that a more productive way of thinking about nature–nurture is to reframe the division as that between product and process (Lickliter & Honeycutt, 2015 ). The phenotype or structure (one’s genetic, epigenetic, anatomical, physiological, behavioral, and mental profile) of an individual at any given time can be considered one’s “nature.” “Nurture” then refers to the set of processes that generate, maintain, and transform one’s nature (Figure 2 ). These processes involve the dynamic interplay between phenotypes and environments.

Figure 2. The developmentalist alternative view of nature–nurture as product–process. Developmentalists view nature and nurture not as separate sources of causation in development (see Figure 1 ) but as a distinction between process (nurture) and product (nature).

It is hard to imagine any set of findings that will end debates about the roles of nature and nurture in human development. Why? First, more so than other assumptions about human development, the nature–nurture dichotomy is deeply entrenched in popular culture and the life sciences. Second, throughout history, the differing positions on nature and nurture were often driven by other ideological, philosophical, and sociopolitical commitments. Thus the essential source of tension in debates about nature–nurture is not as much about research agendas or evidence as about basic differences in metatheoretical positions (epistemological and ontological assumptions) about human behavior and development (Overton, 2006 ).

Nature Versus Nurture and Learning Among Children Essay

The debate on the impact of heredity and environment on the growth and development of human beings has been going on for a long period of time now. Researchers have traced this ageless debate to as long a time ago as the 13 th century. This implies that human beings, particularly researchers are yet to reach a consensus on the significance of nature and nurture on human development.

Those who support the role of nature in human development argue that all behaviour is dictated by genetic or hereditary predispositions that are encoded from the time of conception (Plomin, Corley & Defries, 2007 443). The proponents of the role of nurture in the development of human behaviour emphasise the role of environment in which they are brought up in (Gopnik, 2004 1).

The essay seeks to explore the nature versus nurture debate in relation to the provision of appropriate learning experiences for children. It will then conclude that much of a child’s learning is influenced by both environmental as well as heredity factors.

Psychological researchers have been engaged in an unending debate on whether a child’s development is directly influenced by heredity and other biological factors or it is by the environment in which the child is born and raised. Both sides have advanced undisputable evidence to support their respective sides.

Of much concern among modern researchers is the determination of the degree of influence of nature and nurture on the development of a child and the provision of learning experiences (Gopnik, 2004 3). We shall focus on the impact of both sides of the debate on the child’s learning.

The advocates of the nature theory of human behaviour argue that a child is born with inherent genetic traits that play a central role when it comes to the general development of the child.

They propose that nature provides the child with the necessary capabilities and capacities required for meaningful learning (Plomin et al., 2007 444). According to Gopnik, a renowned professor of psychology, it is by nature that a child is able to learn and influence the environment and interact with it as well (2004).

She argues strongly against the proposal by John Locke who said that a child is born with a blank mind known as “tabula rasa” on which experiences write on it (Plomin et al., 2007 449). Some of the qualities that have been identified as hereditary include; a persons height, behaviour, and intelligence quotient (IQ), among others.

Investigations conducted by nature theorists on twins who were raised in different environments revealed that they could still exhibit notable similarities. The findings further indicated that measures of personality as well as that of temperament, leisure-time and occupational preferences, and attitudes towards social life were much similar among the twins (Plomin et al., 2007 451).This study, therefore, supports the argument that nature plays a great role in child development.

To contrast, another study was conducted on adopted children who shared the same family environment but no genetic relationship. The findings revealed very minimal similarities among the children, but significant similarities with their actual parents (Gopnik, 2004 23). This emphasises the role of genetic factors in the growth and development of human persons.

With the revelation of the key role that nature plays in child development, educators are enlightened on the appropriate learning experiences that they should provide to individual children (Plomin et al., 2007 453). Understanding the child’s background is therefore crucial in ensuring that the child is exposed to the proper experiences as well as detecting any disabilities that may hinder learning. This knowledge helps teachers and parents in designing appropriate learning experiences for each child early enough (Gopnik, 2004 437).

On the other hand, the role of the environment in shaping human behaviour has received as much support as that of heredity. Scientists have established that the way a child is nurtured can help in determining the child’s general personality/capabilities and behaviour (Plomin et al., 2007 454). They have concluded that most behaviours and habits can be learned from the surrounding in which one is brought up.

The diet that a child is given, for instance, has been demonstrated as influencing the development of some capabilities. A study conducted by psychological researchers where some children were given food enriched with vitamins and minerals revealed significant impact of nutrition on intellectual development (Gopnik, 2004 56). The children scored higher on the same nature of intelligence tests that had been given before.

A group of children who had been put on diet which had not been enriched recorded no meaningful improvements on the same intelligence tests (Plomin et al., 2007 455). Apart from enhancing intellectual capabilities, the researchers noted that it was logically correct to conclude that nutrition impacts on the physical capabilities as well.

Nurture theorists further illustrate that if a child is brought up among wild animals, the child would never develop normally when eventually brought back to live among human beings (Plomin et al., 2007 457).

This argument points to the fact that social behaviour is learned from interaction with other people. For educators, the knowledge of the role of environment in shaping behaviour helps them in developing an environment that is conducive for learning in order to facilitate meaningful development (Plomin et al., 2007 458). John Locke, a renowned advocate of the nurture theory regarded a child’s brain as a blank slate where experiences were to be written upon.

This theory also notes that skills like listening, attentiveness, and following instructions are learned from the environment and determines success in school. Hence, educators have realise that a child must be provided with proper experiences that will facilitate the acquisition of crucial qualities that will in turn enhance learning (Gopnik, 2004 87).

The essay has focused on the two sides of the nature/nurture debate and how each plays a role in the development of human behaviour. It is clear that some qualities are inherent in an individual and are independent of environmental influence. On the other hand, some qualities can be enhanced by the exposure of a child to an appropriate environment.

With these considerations in mind, educators must appreciate the role of both genetic as well as environmental factors in child development. Appropriate learning experiences that enhance both of these need to be provided right from childhood.

Nature vs. Nurture

Reviewed by Psychology Today Staff

The expression “nature vs. nurture” describes the question of how much a person's characteristics are formed by either “nature” or “nurture.” “Nature” means innate biological factors (namely genetics ), while “nurture” can refer to upbringing or life experience more generally.

Traditionally, “nature vs. nurture” has been framed as a debate between those who argue for the dominance of one source of influence or the other, but contemporary experts acknowledge that both “nature” and “nurture” play a role in psychological development and interact in complex ways.

The wording of the phrase “nature vs. nurture” makes it seem as though human individuality— personality traits, intelligence , preferences, and other characteristics—must be based on either the genes people are born with or the environment in which they grew up. The reality, as scientists have shown, is more complicated, and both these and other factors can help account for the many ways in which individuals differ from each other.

The words “nature” and “nurture” themselves can be misleading. Today, “ genetics ” and “environment” are frequently used in their place—with one’s environment including a broader range of experiences than just the nurturing received from parents or caregivers. Further, nature and nurture (or genetics and environment) do not simply compete to influence a person, but often interact with each other; “nature and nurture” work together. Finally, individual differences do not entirely come down to a person’s genetic code or developmental environment—to some extent, they emerge due to messiness in the process of development as well.

A person’s biological nature can affect a person’s experience of the environment. For example, a person with a genetic disposition toward a particular trait, such as aggressiveness, may be more likely to have particular life experiences (including, perhaps, receiving negative reactions from parents or others). Or, a person who grows up with an inclination toward warmth and sociability may seek out and elicit more positive social responses from peers. These life experiences could, in turn, reinforce an individual’s initial tendencies. Nurture or life experience more generally may also modify the effects of nature—for example, by expanding or limiting the extent to which a naturally bright child receives encouragement, access to quality education , and opportunities for achievement.

Epigenetics—the science of modifications in how genes are expressed— illustrates the complex interplay between “nature” and “nurture.” An individual’s environment, including factors such as early-life adversity, may result in changes in the way that parts of a person’s genetic code are “read.” While these epigenetic changes do not override the important influence of genes in general, they do constitute additional ways in which that influence is filtered through “nurture” or the environment.

Theorists and researchers have long battled over whether individual traits and abilities are inborn or are instead forged by experiences after birth. The debate has had broad implications: The real or perceived sources of a person’s strengths and vulnerabilities matter for fields such as education, philosophy , psychiatry , and clinical psychology. Today’s consensus—that individual differences result from a combination of inherited and non-genetic factors—strikes a more nuanced middle path between nature- or nurture-focused extremes.

The debate about nature and nurture has roots that stretch back at least thousands of years, to Ancient Greek theorizing about the causes of personality. During the modern era, theories emphasizing the role of either learning and experience or biological nature have risen and fallen in prominence—with genetics gaining increasing acknowledgment as an important (though not exclusive) influence on individual differences in the later 20th century and beyond.

“Nature versus nurture” was used by English scientist Francis Galton. In 1874, he published the book English Men of Science: Their Nature and Nurture , arguing that inherited factors were responsible for intelligence and other characteristics.

Genetic determinism emphasizes the importance of an individual’s nature in development. It is the view that genetics is largely or totally responsible for an individual’s psychological characteristics and behavior. The term “biological determinism” is often used synonymously.

The blank slate (or “tabula rasa”) view of the mind emphasizes the importance of nurture and the environment. Notably described by English philosopher John Locke in the 1600s, it proposed that individuals are born with a mind like an unmarked chalkboard and that its contents are based on experience and learning. In the 20th century, major branches of psychology proposed a primary role for nurture and experience , rather than nature, in development, including Freudian psychoanalysis and behaviorism.

Modern scientific methods have allowed researchers to advance further in understanding the complex relationships between genetics, life experience, and psychological characteristics, including mental health conditions and personality traits. Overall, the findings of contemporary studies underscore that with some exceptions—such as rare diseases caused by mutations in a single gene—no one factor, genetic or environmental, solely determines how a characteristic develops.

Scientists use multiple approaches to estimate how important genetics are for any given trait, but one of the most influential is the twin study. While identical (or monozygotic) twins share the same genetic code, fraternal (or dizygotic) twins share about 50 percent of the same genes, like typical siblings. Scientists are able to estimate the degree to which the variation in a particular trait, like extraversion , is explained by genetics in part by analyzing how similar identical twins are on that trait, compared to fraternal twins. ( These studies do have limitations, and estimates based on one population may not closely reflect all other populations.) 

It’s hard to call either “nature” or “nurture,” genes or the environment, more important to human psychology. The impact of one set of factors or the other depends on the characteristic, with some being more strongly related to one’s genes —for instance, autism appears to be more heritable than depression . But in general, psychological traits are shaped by a balance of interacting genetic and non-genetic influences.

Both genes and environmental factors can contribute to a person developing mental illness. Research finds that a major part of the variation in the risk for psychiatric conditions such as autism spectrum disorder, anxiety disorders, depression, and schizophrenia can be attributed to genetic differences. But not all of that risk is genetic, and life experiences, such as early-life abuse or neglect, may also affect risk of mental illness (and some individuals, based on their genetics, are likely more susceptible to environmental effects than others).

Like other psychological characteristics, personality is partly heritable. Research suggests less than half of the difference between people on measures of personality traits can be attributed to genes (one recent overall estimate is 40 percent). Non-genetic factors appear to be responsible for an equal or greater portion of personality differences between individuals. Some theorize that the social roles people adopt and invest in as they mature are among the more important non-genetic factors in personality development.

ROLES OF NATURE AND NURTURE IN CHILDREN DEVELOPMENT

Daniel Keating

For developmental scientists, the nature versus nurture debate has been settled for some time. Neither nature nor nurture alone provides the answer. It is nature and nurture in concert that shape developmental pathways and outcomes, from health to behavior to competence. This insight has moved far beyond the assertion that both nature and nurture matter, progressing into the fascinating terrain of how they interact over the course of development. In this book, students, practitioners, policy analysts, and others with a serious interest in human development will learn what is transpiring in this new paradigm from the developmental scientists working at the cutting edge, from neural mechanisms to population studies, and from basic laboratory science to clinical and community interventions. Early childhood development is the critical focus of this book, because many of the important nature-nurture interactions occur then, with significant influences on lifelong developmental trajectories.

The concepts of nature and nurture shape the development of human beings. This write up sets out to assess the nature nurture debate, pinpointing the effects each has on the development of children. Terms that will be defined are nature nurture debate, nature and nurture. Feldman (2009) defines the nature nurture debate as the issue of the degree to which environment and hereditary factors influence the behaviour. According to Flanagan (2002) nature refers to behavioural or physical traits found in a developing child that are due to genetic factors. Feldman (2009:39) says “nature refers to hereditary factors, characteristics and tendencies that influence development.” Thus nature can be defined as inborn characteristics such as generic diseases evident in a developing child. Santrock (2004) defines nurture as environmental factors that have an influence on the development of a human being. According to Bernstein (2011) nurture refers to all environmental influence, after the birth of a child that affects development. Hence nurture can be called post natal factors that influence development of people. Lahey

The purpose of this paper is to expose the differences and similarities between nature and nurture. How they correlate to each other, and shape human development. Without nature and nurture, we would all be the same, and have the same experiences. This controversial topic is one of the oldest arguments in psychology. Nature vs. Nurture states that feelings, ideas, and human behavior are innate or learned. I will be writing about when this debate first rooted, and why. I will be arguing that we are born with certain characteristics in our thinking, that are then shaped by our experiences. I will then examine about how genes do affect our behavior, and how the environment shapes behavior. To fully uncover the nature and nurture, I will conduct thorough research on the topic in autism and twins. These two case studies will help to dissect the critical issue of nurture and nature. In the thesis, I will look into different scholars’ view on the nature and nurture topic.

Nature versus Nurture Debate in Psychology by Hunter Honeycutt LAST REVIEWED: 12 January 2023 LAST MODIFIED: 12 January 2023 DOI: 10.1093/obo/9780199828340-0305

The nature-nurture dichotomy is a long-standing and pervasive framework for thinking about the causal influences believed to be operating during individual development. In this dichotomy, nature refers to factors (e.g., genes, genetic programs, and/or biological blueprints) or forces (e.g., heredity and/or maturation) inherent to the individual that predetermine the development of form and function. Nurture generally refers to all the remaining, typically “external,” causal factors (e.g., physical and social conditions) and processes (e.g., learning and experience) that influence development. The nature versus nurture debate in psychology deals with disagreements about the extent to which the development of traits in humans and animals reflects the relative influence of nature and nurture. It is commonly stated that psychologists have moved on from asking whether traits (or variation in traits) develop from nature or nurture, to recognize instead that both nature and nurture work together or “interact” to produce outcomes, although exactly how to view the interaction is a matter of much debate. While acknowledging the interaction of nature and nurture, one’s theoretical models and research focus might emphasize the prominence of one over the other. Thus, nativists focus more on the importance of innate factors or forces operating on development, whereas empiricists focus more on experiential or environmental factors. However, not everyone finds value in thinking about development in terms of nature and nurture. By the middle of the twentieth century, some psychologists, biologists, and philosophers began to view nature-nurture as a conceptually deficient and biologically implausible dichotomy that oversimplifies the dynamics of behavior and development. Such people espouse some variant of “developmental systems theory” and seek to eliminate or otherwise fuse the nature-nurture division.

The works in this section are mostly trade books that provide general introductions to the nature-nurture debate across a variety of topical areas in psychology, all of which would be suitable for use in classes with undergraduate students at all levels. Goldhaber 2012 contrasts four popular perspectives on the nature-nurture issue and would be a good place to start for anyone unfamiliar with the nature-nurture debate in psychology. Nativist perspectives are represented by Pinker 2002 , Plomin 2018 , and Vallortigara 2021 . An empiricist-leaning position on behavior development is put forth in Schneider 2012 . Developmental systems theory is promoted in Blumberg 2005 and Moore 2002 . Two edited books are included and both are better suited for advanced undergraduate- or graduate-level students. The first edited book, Coll, et al. 2013 , focuses on the nature-nurture issue across a range of topics and perspectives in psychology. The other, Mayes and Lewis 2012 , presents empiricist (or environmentalist) perspectives on child development.

Bateson, P. 2017. Behaviour, development and evolution . Cambridge, UK: OpenBook Publishers.

DOI: 10.11647/OBP.0097

Written by a distinguished ethologist who draws extensively from his work on animal behavior, this book argues that the nature-nurture division is neither valid nor helpful in capturing the complex system of factors that influence behavioral development. Topics include imprinting and attachment, parent-offspring relations, the influence of early-life experiences on later-life outcomes, problems with genetic determinism, and the role of behavior in evolutionary change.

Blumberg, M. S. 2005. Basic instinct: The genesis of novel behavior . New York: Thunder’s Mouth Press.

Consistent with developmental systems theory, Blumberg presents an overview of the conceptual and empirical limitations of nativism in explanations of behavioral and neural development in animals and cognitive development in humans.

Coll, C. G., E. L. Bearer, and R. M. Lerner, eds. 2013. Nature-nurture: The complex interplay of genetic and environmental influences on human behavior and development . New York: Psychology Press.

The contents of this edited volume are almost entirely original works with commentary that span multiple disciplines (psychology, biology, economics, philosophy) and multiple perspectives (behavioral genetics and developmental systems theory) on the nature-nurture issue.

Goldhaber, D. 2012. The nature-nurture debates: Bridging the gap . Cambridge, UK: Cambridge Univ. Press.

DOI: 10.1017/CBO9781139022583

Goldhaber reviews four major perspectives (behavior genetics, environmentalism, evolutionary psychology, and developmental systems theory) on the nature-nurture issue. He argues we should reject reductionist views based on either genetic determinism or environmental determinism in favor of more holistic, interactionist approaches.

Mayes, L. C., and M. Lewis, eds. 2012. The Cambridge handbook of environment in human development . Cambridge, UK: Cambridge Univ. Press.

This handbook explores a wide variety of ways in which the environment influences child development. Chapters cover conceptual frameworks and methodological issues in thinking about and studying environmental influences as well reviewing ways in which environmental contexts and systems influence specific aspects of child development.

Moore, D. S. 2002. The dependent gene: The fallacy of nature vs. nurture . New York: Henry Holt.

This book provides an introduction to the developmental systems theory take on the nature-nurture issue particularly as it relates to genetic determinism, heritability and heredity.

Pinker, S. 2002. The blank slate: The modern denial of human nature . New York: Viking.

In this best-selling book, Pinker draws on evidence from behavioral genetics, evolutionary psychology, and cognitive psychology to argue for a nativist position concerning human nature.

Plomin, R. 2018. Blueprint: How DNA makes us who we are . Cambridge, MA: MIT Press.

Plomin reviews traditional and more modern evidence from behavioral genetics to argue that genes are the primary factor in bringing about psychological differences between people. Moreover, he argues that many “environmental” factors operating on development are themselves strongly influenced by genetic differences.

Schneider, S. M. 2012. The science of consequences: How they affect genes, change the brain, and impact our world . Amherst, NY: Prometheus Books.

Schneider presents a view grounded in behavior analysis to argue for the critical role that the consequences of genetic activity, neural activity, and behavioral activity play in individual development. While emphasizing environmental (or experiential) factors influencing development, this book also highlights the systemic and interactive nature of developmental systems across multiple levels of analysis.

Vallortigara, G. 2021. Born knowing: Imprinting and the origins of knowledge . Cambridge, MA: MIT Press.

DOI: 10.7551/mitpress/14091.001.0001

Drawing upon research in comparative cognition and comparative neuroscience, much of it his own, Vallortigara argues that animals, including humans, enter the world with a set of unlearned, innate or instinctive behaviors and neural circuits that bias or predispose subsequent learning and development.

What Are Nature vs. Nurture Examples?

How is nature defined, how is nurture defined, the nature vs. nurture debate, nature vs. nurture examples, what is empiricism (extreme nurture position), contemporary views of nature vs. nurture.

Nature vs. nurture is an age-old debate about whether genetics (nature) plays a bigger role in determining a person's characteristics than lived experience and environmental factors (nurture). The term "nature vs. nature" was coined by English naturalist Charles Darwin's younger half-cousin, anthropologist Francis Galton, around 1875.

In psychology, the extreme nature position (nativism) proposes that intelligence and personality traits are inherited and determined only by genetics.

On the opposite end of the spectrum, the extreme nurture position (empiricism) asserts that the mind is a blank slate at birth; external factors like education and upbringing determine who someone becomes in adulthood and how their mind works. Both of these extreme positions have shortcomings and are antiquated.

This article explores the difference between nature and nurture. It gives nature vs. nurture examples and explains why outdated views of nativism and empiricism don't jibe with contemporary views.

In the context of nature vs. nurture, "nature" refers to genetics and heritable factors that are passed down to children from their biological parents.

Genes and hereditary factors determine many aspects of someone’s physical appearance and other individual characteristics, such as a genetically inherited predisposition for certain personality traits.

Scientists estimate that 20% to 60% percent of temperament is determined by genetics and that many (possibly thousands) of common gene variations combine to influence individual characteristics of temperament.

However, the impact of gene-environment (or nature-nurture) interactions on someone's traits is interwoven. Environmental factors also play a role in temperament by influencing gene activity. For example, in children raised in an adverse environment (such as child abuse or violence), genes that increase the risk of impulsive temperamental characteristics may be activated (turned on).

Trying to measure "nature vs. nurture" scientifically is challenging. It's impossible to know precisely where the influence of genes and environment begin or end.

How Are Inherited Traits Measured?

“Heritability”   describes the influence that genes have on human characteristics and traits. It's measured on a scale of 0.0 to 1.0. Very strong heritable traits like someone's eye color are ranked a 1.0.

Traits that have nothing to do with genetics, like speaking with a regional accent ranks a zero. Most human characteristics score between a 0.30 and 0.60 on the heritability scale, which reflects a blend of genetics (nature) and environmental (nurture) factors.

Thousands of years ago, ancient Greek philosophers like Plato believed that "innate knowledge" is present in our minds at birth. Every parent knows that babies are born with innate characteristics. Anecdotally, it may seem like a kid's "Big 5" personality traits (agreeableness, conscientiousness, extraversion, neuroticism, and openness) were predetermined before birth.

What is the "Big 5" personality traits

The Big 5 personality traits is a theory that describes the five basic dimensions of personality. It was developed in 1949 by D. W. Fiske and later expanded upon by other researchers and is used as a framework to study people's behavior.

From a "nature" perspective, the fact that every child has innate traits at birth supports Plato's philosophical ideas about innatism. However, personality isn't set in stone. Environmental "nurture" factors can change someone's predominant personality traits over time. For example, exposure to the chemical lead during childhood may alter personality.

In 2014, a meta-analysis of genetic and environmental influences on personality development across the human lifespan found that people change with age. Personality traits are relatively stable during early childhood but often change dramatically during adolescence and young adulthood.

It's impossible to know exactly how much "nurture" changes personality as people get older. In 2019, a study of how stable personality traits are from age 16 to 66 found that people's Big 5 traits are both stable and malleable (able to be molded). During the 50-year span from high school to retirement, some traits like agreeableness and conscientiousness tend to increase, while others appear to be set in stone.

Nurture refers to all of the external or environmental factors that affect human development such as how someone is raised, socioeconomic status, early childhood experiences, education, and daily habits.

Although the word "nurture" may conjure up images of babies and young children being cared for by loving parents, environmental factors and life experiences have an impact on our psychological and physical well-being across the human life span. In adulthood, "nurturing" oneself by making healthy lifestyle choices can offset certain genetic predispositions.

For example, a May 2022 study found that people with a high genetic risk of developing the brain disorder Alzheimer's disease can lower their odds of developing dementia (a group of symptoms that affect memory, thinking, and social abilities enough to affect daily life) by adopting these seven healthy habits in midlife:

  • Staying active
  • Healthy eating
  • Losing weight
  • Not smoking
  • Reducing blood sugar
  • Controlling cholesterol
  • Maintaining healthy blood pressure

The nature vs. nurture debate centers around whether individual differences in behavioral traits and personality are caused primarily by nature or nurture. Early philosophers believed the genetic traits passed from parents to their children influence individual differences and traits. Other well-known philosophers believed the mind begins as a blank slate and that everything we are is determined by our experiences.

While early theories favored one factor over the other, experts today recognize there is a complex interaction between genetics and the environment and that both nature and nurture play a critical role in shaping who we are.

Eye color and skin pigmentation are examples of "nature" because they are present at birth and determined by inherited genes. Developmental delays due to toxins (such as exposure to lead as a child or exposure to drugs in utero) are examples of "nurture" because the environment can negatively impact learning and intelligence.

In Child Development

The nature vs. nurture debate in child development is apparent when studying language development. Nature theorists believe genetics plays a significant role in language development and that children are born with an instinctive ability that allows them to both learn and produce language.

Nurture theorists would argue that language develops by listening and imitating adults and other children.

In addition, nurture theorists believe people learn by observing the behavior of others. For example, contemporary psychologist Albert Bandura's social learning theory suggests that aggression is learned through observation and imitation.

In Psychology

In psychology, the nature vs. nurture beliefs vary depending on the branch of psychology.

  • Biopsychology:  Researchers analyze how the brain, neurotransmitters, and other aspects of our biology influence our behaviors, thoughts, and feelings. emphasizing the role of nature.
  • Social psychology: Researchers study how external factors such as peer pressure and social media influence behaviors, emphasizing the importance of nurture.
  • Behaviorism: This theory of learning is based on the idea that our actions are shaped by our interactions with our environment.

In Personality Development

Whether nature or nurture plays a bigger role in personality development depends on different personality development theories.

  • Behavioral theories: Our personality is a result of the interactions we have with our environment, such as parenting styles, cultural influences, and life experiences.
  • Biological theories: Personality is mostly inherited which is demonstrated by a study in the 1990s that concluded identical twins reared apart tend to have more similar personalities than fraternal twins.
  • Psychodynamic theories: Personality development involves both genetic predispositions and environmental factors and their interaction is complex.

In Mental Illness

Both nature and nurture can contribute to mental illness development.

For example, at least five mental health disorders are associated with some type of genetic component ( autism ,  attention-deficit hyperactivity disorder (ADHD) ,  bipolar disorder , major depression, and  schizophrenia ).

Other explanations for mental illness are environmental, such as:

  • Being exposed to drugs or alcohol in utero 
  • Witnessing a traumatic event, leading to post-traumatic stress disorder (PTSD)
  • Adverse life events and chronic stress during childhood

In Mental Health Therapy

Mental health treatment can involve both nature and nurture. For example, a therapist may explore life experiences that may have contributed to mental illness development (nurture) as well as family history of mental illness (nature).

At the same time, research indicates that a person's genetic makeup may impact how their body responds to antidepressants. Taking this into consideration is important for finding the right treatment for each individual.

 What Is Nativism (Extreme Nature Position)?

Innatism emphasizes nature's role in shaping our minds and personality traits before birth. Nativism takes this one step further and proposes that all of people's mental and physical characteristics are inherited and predetermined at birth.

In its extreme form, concepts of nativism gave way to the early 20th century's racially-biased eugenics movement. Thankfully, "selective breeding," which is the idea that only certain people should reproduce in order to create chosen characteristics in offspring, and eugenics, arranged breeding, lost momentum during World War II. At that time, the Nazis' ethnic cleansing (killing people based on their ethnic or religious associations) atrocities were exposed.

Philosopher John Locke's tabula rasa theory from 1689 directly opposes the idea that we are born with innate knowledge. "Tabula rasa" means "blank slate" and implies that our minds do not have innate knowledge at birth.

Locke was an empiricist who believed that all the knowledge we gain in life comes from sensory experiences (using their senses to understand the world), education, and day-to-day encounters after being born.

Today, looking at nature vs. nature in black-and-white terms is considered a misguided dichotomy (two-part system). There are so many shades of gray where nature and nurture overlap. It's impossible to tease out how inherited traits and learned behaviors shape someone's unique characteristics or influence how their mind works.

The influences of nature and nurture in psychology are impossible to unravel. For example, imagine someone growing up in a household with an alcoholic parent who has frequent rage attacks. If that child goes on to develop a substance use disorder and has trouble with emotion regulation in adulthood, it's impossible to know precisely how much genetics (nature) or adverse childhood experiences (nurture) affected that individual's personality traits or issues with alcoholism.

Epigenetics Blurs the Line Between Nature and Nurture

"Epigenetics " means "on top of" genetics. It refers to external factors and experiences that turn genes "on" or "off." Epigenetic mechanisms alter DNA's physical structure in utero (in the womb) and across the human lifespan.

Epigenetics blurs the line between nature and nurture because it says that even after birth, our genetic material isn't set in stone; environmental factors can modify genes during one's lifetime. For example, cannabis exposure during critical windows of development can increase someone's risk of neuropsychiatric disease via epigenetic mechanisms.

Nature vs. nurture is a framework used to examine how genetics (nature) and environmental factors (nurture) influence human development and personality traits.

However, nature vs. nurture isn't a black-and-white issue; there are many shades of gray where the influence of nature and nurture overlap. It's impossible to disentangle how nature and nurture overlap; they are inextricably intertwined. In most cases, nature and nurture combine to make us who we are.

In this essay, I explore what social science might contribute to building a better understanding of relations between ‘nature’ and ‘nurture’ in human development. I first outline changing scientific perspectives on the role of the environment in the developmental and behavioural sciences, beginning with a general historical view of the developmental science of human potentials in the twentieth century, and then reflecting on a call to arms against ‘toxic stress’ issued in 2012 by the American Academy of Pediatrics. I suggest that such post-genomic programmes of early intervention, which draw on emerging scientific theories of organismic plasticity and developmental malleability, raise significant social and ethical concerns. At the same time, such programmes challenge social scientists to move beyond critique and to contribute to new developmental models that deconstruct the old divide between nature and nurture. I conclude by describing efforts that posit new terms of reference and, simultaneously, new kinds of research interests and questions that are not founded upon, and are not efforts to resolve, the nature–nurture debate.

Some of this history is covered in Singh (2002) , and far more completely in Shorter (1997) .

Fox Keller takes the phrase ‘system of inheritance’ from Jablonka and Lamb (2005) .

To be fair, this is a quotation from an interview with a journalist. Shonkoff is also the lead author of the toxic stress report in Pediatrics , which suggests a more sophisticated understanding of the science. Nevertheless, it is important to note the continued salience of claims to have discovered the ‘biology of (insert socially undesirable status or behavior)’.

Interestingly, there were no positive effects of intervention on boys born to visited mothers, which should raise a question of the overall success of the programme, given that men are more likely than women to be arrested and convicted of crimes.

Nature vs. Nurture in Child Psychology

Introduction, the arising influence, intelligence quotient, nurture’s effects, nature’s effects.

Children depend wholly on their parents or guardians for support and care. At birth, they have hereditary material (genetic effects) acquired from their parents, and as they grow, they experience the influence of the psychological, social, and physical settings (environmental aspects). Children develop quickly in all spheres of life: psychological, cognitive, biological, and social (Charney, 2013). Are the life changes already preset as they grow? Are the experiences of their early years (environmentally stimulated) able to determine what will occur in their later lives?

Changes in a child’s development are consistent all through life as they mark a lifetime progression of losses and gains. Most of such transformations happen in expected patterns. Though the continuous development of children may occur predictably, the extent of change and the time of occurrence differ from one child to the other (Harold et al., 2013). In the past, genetic (nature) and nonhereditary (nurture) factors were believed to operate independently. Nevertheless, after a period of debate, it has been established that environmental and genetic factors are vital aspects, development is an amalgamation of both, and they have to function dependently. On this note, possibly the issue of “nature vs. nurture” ought to be changed to “nature and nurture.”

The nature versus nurture discourse concerns the relative impact of a person’s natural qualities when judged against the influence of the surroundings that he/she is brought up in, in the establishment of personal differences in behavioral and physical characteristics. There is an extensive perception that human beings obtain all or the majority of their behavioral attributes from “nurture.” In contemporary times, both nature and nurture have been seen to play a crucial role in human development and behavior (Harold et al., 2013). The nature vs. nature debate considers the degree to which considerable factors of conduct have been triggered either by genetic (hereditary) or learned (acquired) attributes (Sobrin & Seddon, 2014). While nature considers what is thought to be pre-wiring and emanating from genetic and biological aspects, nurture is the impact of external facets that occur after birth (for instance, learning, experience, and exposure).

A child’s physical characteristics may be deemed identical to those of parents, for instance, a baby could have a hair color that is similar to the mother’s. Nevertheless, a child’s personality and abilities might fail to match those of either parent (Harold et al., 2013). The surroundings in which children are brought up might have a lifelong impact on the manner in which they communicate, act, and react to situations around them. The arguments in the nurture versus nature debate make it difficult to determine whether some characteristics in the development of a child are predisposed in his/her genetic material or occurrences in his/her environment.

In contemporary times, studies have made it clear that both nurture and nature have a fundamental function in human behavior and development. Every child is born with a natural psychological ability that enables them to learn how to act and produce language (Charney, 2013). Since most of the child’s behaviors are associated with the influence of the environment, the way in which a child behaves may be connected to factors such as parenting approaches and learned practices. For instance, a child might learn from people around him/her to say ‘thank you’ and ‘please’ while another may be influenced into becoming hostile through constantly watching the violent behavior of other older children.

It has for a long time been identified that some physical attributes and conditions such as curly/straight hair and albinism respectively are biologically influenced by genetic factors (Harold et al., 2013). Other physical attributes, if not being directly established, seem to be at least powerfully swayed by the genetic composition of biological parents. A child’s body weight, height, baldness (in males), life expectancy, and susceptibility to particular diseases (for example, breast cancer in females) are strongly associated amid genetically linked people. Such concerns have resulted in many people contemplating whether psychological attributes that encompass behavioral inclinations, personality aspects, and intellectual capacities occur naturally in a child as they are all genetically inherited. The individuals who acquire a strongly heritable position are referred to as nativists. Charney (2013) affirms that the attributes of human beings in entirety are influenced by evolution and that personal differences happen because of every individual’s exceptional genetic code. On this note, the earlier a given attribute emerges, the higher the likelihood of it being influenced by genetic characteristics.

Attributes and differences which are not decipherable immediately after birth and that occur in later life, are taken to be results of maturation (Harold et al., 2013). This signifies that every person has an internal genetic clock whose operation depends on the nature of behavior in a preset manner. Some of the excellent instances of the manner in which this influences a child’s physical development are the bodily transformations that happen at the onset of the adolescent during the teenage years. Nevertheless, nativists affirm that continued maturation in a child influences the concerns of connection in formative years, language development, and cognitive advancement altogether (Harold et al., 2013). At a different phase of the argument are the environmentalists, also referred to as empiricists, whose fundamental presupposition is that the mind of a baby is at a blank state during delivery and that it is progressively filled with time due to a child’s experiences (behaviorism).

From the nurture’s standpoint, psychological attributes and behavioral dissimilarities that arise in the course of childhood and adolescence hail from learning (Charney, 2013). The way in which a child is brought up (nurtured) dictates the essential factors of a child’s psychological development and the period of maturation just influences the biological factors. For instance, the moment a baby starts developing a connection, it is reacting to the love and care that it gets, language acquisition relies on the imitation of the words of other people, and cognitive advancement relies on the extent of arousal in the surroundings and, more expansively, on the society within which a child is brought up. Bowlby’s theory of attachment offers views on the position of nature in the psychological development of a child (Tammen, Friso, & Choi, 2013). It considers the connection between the mother and her baby as an inborn progression that guarantees continued existence. Moreover, language development in a child is enhanced by the natural language acquisition ability.

The social learning theory asserts that conducts such as violent behavior are learned from the surroundings via simulation and observation (Sobrin & Seddon, 2014). In line with the theory, some behaviors of children develop through being influenced by the conduct of others. This has a great impact on the behavior of the adult that the child turns out to be in later life. Furthermore, a child learns language from the people that he/she shares the same environment through behavior determining approaches. In practice, barely any person in the modern world accepts or rejects the extreme points of view in nature versus nurture debate (Bartelt & Dennis, 2014). There are just too many facts on either position of the debate. In this regard, rather than seeking to know if nurture or nature influences the traits of children, studies have increasingly centered on the inquiry: To what extent? In simple terms, what is of significance in the modern world is establishing the one that is more influential since both the environment and genes contribute to the development of a child.

In contemporary times, there has been a mounting realization that the inquiry of the extent of conduct is based on genetics while the influence of the environment might itself be a mistaken issue (Tammen et al., 2013). While considering intelligence, it is evident that (like nearly all forms of human conduct), it is an intricate, multi-sided occurrence that either conceals or discloses itself in numerous ways. Wanting to know the magnitude of the influence is presuming that every variable may be presented numerically and the impact might be determined in a quantitative approach. The truth is that culture and nature interrelate in a multitude of qualitatively diverse approaches (Charney, 2013). It is extensively agreed that the environment and genetics do not operate dependently; nurture and nature are both fundamental for behavioral occurrences, and it is difficult to prove that a given behavior is heritable while the other is triggered by the environment. It is impractical to disconnect the two factors since they network in an intricate style.

Rather than supporting the nurturist or nativist point of view, the majority of researchers in the field of psychology have chosen to evaluate the manner in which nurture and nature interconnect (Sobrin & Seddon, 2014). For instance, in psychopathology, it has been established that both hereditary inclinations and a suitable environmental prompt are necessary for the development of mental health disorders. This makes it impossible to prove that one of the factors is fully accountable. It makes sense to assert that the dissimilarity amid people’s behavior is mainly attributable to hereditary aspects or largely because of environmental triggers. Such apprehension is particularly significant given the contemporary advancements in genetics (Tammen et al., 2013).

For instance, the Human Genome Scheme has triggered much concern in linking forms of conduct to specific strands of deoxyribonucleic acid positioned on some chromosomes. A wide pool of studies affirms that scientists are on the brink of realizing the gene responsible for criminality, alcohol abuse, and homosexuality. In case the arising advancements are not abused, there will be a necessity for the comprehension of the aspect of biology interrelating with the cultural factors and the personal inclinations that human beings realize concerning their lives. There is yet to be an easy and neat means of unraveling the quantitatively unlike and common influences on a child’s development and human conduct.

Glausiusz (2016) believes that the intellectual capacity of a child is greatly inherited and the inclination of genius children being born in the same family is a product of natural dominance. Such a perspective has consistently been cropping up in psychology thereby eliciting studies into intelligence assessment (especially on adopted children and twins). After the establishment that the average intelligence quotient (IQ) score for African Americans is considerably less when judged against that of the whites, studies have continued to affirm that genetic aspects are mostly accountable, to the point of implying that intelligence is 80% hereditary. Fox (2017) is convinced that the human species may be improved through enhanced breeding. On this note, there once arose a campaign for the sterilization of both male and female patients with psychiatric disorders. Currently, many researchers think that the immigration laws in Britain were implemented for discrimination against Asian and African racial groups.

For the majority of environmentalists, there is a greatly contested notion regarding the impact of behavioral genetics. In their viewpoint, Tammen et al. (2013) allege that the IQ score of varying racial groups is attributable to innate prejudices in the techniques of assessment. More essentially, they affirm that dissimilarities in intellectual capacity are outcomes of social inequities in the availability of funds, knowledge, and opportunities. This way, it is believed that the children that grow up in ghetto areas have an inclination towards scoring less in IQ tests since they lack access to the advanced life opportunities which the wealthy and privileged individuals in the nation have. The reasons behind the nurture vs. nature issue turning out to be a strongly pondered topic are now apparent (Bartelt & Dennis, 2014). An issue that began as an effort to comprehend the basis of behavioral divergences changed to a politically propelled controversy regarding distributive influence and impartiality in the community, and affected not just IQ but similarly the concerns of gender, sex, and culture.

Research implies that environmental influences in a family might have a considerable effect on the IQ of children, which makes up about a quarter of the variation (Sobrin & Seddon, 2014). On the contrary, by late adolescence, the connection ebbs out to the extent that adoptive siblings are no more alike in intelligent quotient than aliens (Bartelt & Dennis, 2014). Besides, adoption research shows that by the time they become adults, adoptive children have an intelligent quotient akin to that of aliens (with almost no relationship) whereas siblings have an intelligence quotient relationship of approximately 0.7. The research on twins strengthens the connection with the identical ones who have been brought up in different environments having an intelligence quotient score of about 0.9 and fraternal ones nurtured together 0.7. With respect to the nature vs. nurture discourse, the “nature” element seems more essential when judged against the “nurture” one when it comes to the explanation of intelligence quotient variation.

Numerous rationales may seem incapable of being swayed by environmental cues even when they actually are (Sobrin & Seddon, 2014). For example, some of the aspects that control a child’s behavior occur in the prenatal settings, and there is minimal chance of directly observing their impacts, which may be considerable nonetheless. There is proof that the food that a mother consumes can influence the baby’s taste for some flavors or result in the child becoming schizoid or obese in later life (Montag et al., 2016). On the same note, the voices that a baby hears while in the uterus may have an impact on their behavioral attributes after birth. Morphological qualities that occur prenatally, a grouping that encompasses things such as facial bones, as well appear because of the arising interrelations between hereditary and nonhereditary aspects within the uterus.

Most of the factors that could influence a child’s behavior are consistent across the developmental surroundings, which makes it hard to perceive their impact (Sobrin & Seddon, 2014). Since all children are brought up in settings that have, for example, gravity and oxygen, grownups that keep communicating, and different nutrients, it is not possible to see the influence of such environmental facets casually. However, the facets have a possibility of containing considerable effects on the emergence of a child’s characteristics, even in cases where they cannot be invoked to explain divergences amid children (Bartelt & Dennis, 2014). Though some nutrients are responsible for influencing the color of hair in a child, the impact of such an environmental aspect is not readily evident since in most regions across the globe there have plenty of the necessary nutrients to the extent that no child can be malnourished in a manner that would show the nutritional impact on hair color clearly. Similarly, the noteworthy task of gravity in the enhancement of normal human motor coordination was undetected until when it became possible to assess the effect on other animals such as rats.

A number of the aspects that control a child’s attributes are highly faint and may easily escape without realization (Bartelt & Dennis, 2014). Research on different animals has shown a diversity of impacts of environmental stimuli on the development of characteristics in children, concerns that may have a non-apparent connection to the stimuli accountable for their production. For instance, introducing chicks to their toes could result in their consumption of mealworms, and including crickets or grasshoppers in the food of squirrel monkeys results in their dread of snakes (Montag et al., 2016). Taking into consideration the difficulty of establishing such connections that appear entirely unpredictable, non-noticeable environmental contributors to development may eventually be perceived as a class that contains a huge number of dominant environmental aspects yet to be identified.

Though several aspects that influence the establishment of traits in children are not hereditary, they are, however, not biological; for instance, steroid hormones (Bartelt & Dennis, 2014). Such chemicals cannot be classified under the description of nature in behavioral genetics (since they are not genetic), and their production within the body cannot fit in the confines of nurture. Testosterone represents a steroid hormone that controls the development of psychological attributes such as hostility and spatial cognition (Montag et al., 2016). The influence of this hormone on such attributes signifies that the experiences a child has that manipulate the amount of testosterone may influence their conduct.

Notably, testosterone’s effects would be factual irrespective of whether such an experience is one that people would normally relate to nurturing (Montag et al., 2016). For instance, the moment that the rate of salivary testosterone production is influenced by engagement in athletic competition, people would take that to be an impact of nurture (because one child could get involved in athletic competition more than another). On the contrary, though the increase in testosterone production at puberty carries a similar effect, it might typically not be linked to nurturing. On this note, researchers have sought a wide and relational depiction of experiences that encompass other behaviors apart from the ones clearly involving learning. Can testosterone be deemed an effect of nurture or nature? Such a question does not seem sensible with respect to the understanding of scientists regarding the way molecules in the body are influenced genetically and through experience.

Some environmental aspects that have an impact on development occur in the uterus, others invariably exist in human developmental settings, and several perform in exceedingly subtle approaches, and people fail to discover numerous occurrences as environmentally triggered (since although they are not hereditary and may be controlled by the external surroundings, they happen inside the body of an individual). In any case, the impact of such incidences is difficult to identify. In this regard, casual observation at times implies that a child has several traits that are entirely uninfluenced by nurture (Fox, 2017). Nonetheless, since genes just articulate their effects in contexts and their impact sways their operations, the genome may be considered reactive and nonhereditary aspects have to be taken to function always in the occurrence of characteristics in children.

The entire compilation of the genetic material (genes) is referred to as the human genome (Glausiusz, 2016). The developments in technology and studies on genetic material have enabled researchers to understand the influence of heredity on a child’s development. Human beings inherit their hereditary factors from biological parents and genes represent the essential constituent of the genetic material as they hold the heritable information, directions for biological performance, and inborn traits. The genes from both the mother and the father merge to create the child’s genetic material. The hereditary material exists in the nature of thread-like pieces referred to as chromosomes. The majority of the cells in the body contain 23 pairs of chromosomes where each constituent in a pair is inherited from the father and the other from the mother. One amid the 23 pairs of chromosomes consists of sex chromosomes, which are responsible for the child’s gender, whether male or female. If the pair is made up of two X chromosomes, the child will be female, while children turn out to be made in cases where the pair contains an X and a Y chromosome.

Chromosomes consist of deoxyribonucleic acid, which is made up of genes, a child’s hereditary blueprint that sways his or her developmental conduct (Glausiusz, 2016). The identification and assessment of the genetic material that makes each child unique are intricate and early impracticable. A number of traits, nevertheless, are obvious instances of inheritance. Such encompass attributes that are influenced by one pair of chromosomes, for example, the ability to roll one’s tongue, the appearance of a child’s earlobes, green or red color blindness, the tallness of the second toe, and existence or nonexistence of widow’s peak. A child can have the ability to roll his/her tongue or not, a hereditary characteristic that cannot be taught (Fox, 2017). Children who can roll their tongue have inherited at least one “tongue-rolling” genetic material from their parents.

Since genes occur in pairs, in most instances, one chromosome in the pair might be dominant when judged against the other (the recessive gene). The characteristics of the dominant gene in the pair have to show irrespective of the existence of the other chromosome (Montag et al., 2016). In a case where the dominant gene is the “tongue-rolling” one, a child will have the ability to roll his/her tongue even if the recessive gene is “non-tongue-rolling.” The characteristics of a recessive gene are only evident when there are two of such in a pair. Every person is influenced by environmental factors in an exceptional manner. The influence of both genetic and nonhereditary aspects is exceedingly intricate and hard to disconnect. Several attributes of development such as learning to babble and vocalize in infancy seem to be coded in the genetic material with little or no manipulation of the environment. In this regard, all babies around the globe, encompassing the ones that have hearing problems, babble in a similar manner.

Some of the children’s attributes, for instance, personality and astuteness, are swayed by environmental aspects, though hereditary material usually seems to mark boundaries and restrictions (Glausiusz, 2016). Though a child could have been born with the hereditary factors that enable him/her to attain a high degree of intelligence, it is not guaranteed that they will achieve such a level. However, with the availability of the most suitable environmental situation, comprising of good health, food, and safe and favorable surroundings, they have a high possibility of growing up to achieve their intellectual capacity. Experiencing poor conditions, for example, undernourishment, illness, negligence, or exposure to harmful chemicals, may make children have poor intelligence levels and the inability to realize their potential. Height is another characteristic that could be swayed by the interrelation of nurture and nature considerably (Fox, 2017). A child may hail from a family of tall people, inherit the genetic materials for tallness, and end up becoming short. Growing up in an unfavorable environment where the child does not obtain suitable nourishment may make him/her fail to realize the height that she/he could have attained had he/she been brought up in a healthy environment.

Children depend utterly on their parents or caregivers for support and care. In the course of formation within the womb, they have hereditary material acquired from their parents, and after birth, they go through the influence of the emotional, social, and physical settings (the environment). In the past, inherited (nature) and nonhereditary (nurture) features were believed to work independently. Nonetheless, after a period of debate, it has been found that environmental and inherent factors are imperative aspects, development is a union of both, and they have to operate dependently. On this note, probably the issue of “nature vs. nurture” should be altered to “nature and nurture.”

While nature mulls over what is deemed pre-wiring and springs from heritable and biological facets, nurture is the impact of external occurrences that transpire after birth (for example, learning, practice, and exposure). The physical characteristics of a child may be deemed indistinguishable to those of parents, for instance, a child could have a hair color that is akin to the mothers. Nevertheless, a child’s qualities and abilities might fail to equal those of either parent. The setting in which children are raised might have a permanent impact on their way of communicating, acting, and reacting to circumstances around them. For instance, children may learn from individuals around them to use words such as ‘thank you’ and ‘please’ while others might be influenced into becoming unfriendly through continually watching the violent actions of other older people.

Essay on Playground in 500 Words

Playgrounds serve as more than mere recreational spaces; they are essential arenas for fostering children’s holistic development. With a blend of physical challenges, social interactions, and cognitive stimulation, playgrounds play a pivotal role in shaping the future generation.

Physical Development

At the heart of playgrounds lies the promotion of physical activity, crucial for developing gross motor skills, balance, and coordination. Climbing structures strengthen muscles, while swings promote sensory integration and spatial awareness. The varied terrain encourages exploration, enhancing agility and proprioception. Additionally, outdoor play fosters a connection with nature, promoting healthier lifestyles and reducing the risk of childhood obesity.

Social Interaction

Playgrounds act as bustling hubs where children learn vital social skills. Through unstructured play, they navigate social dynamics, negotiate conflicts, and develop empathy. Cooperative games foster teamwork and communication, while imaginative play encourages creativity and problem-solving. Moreover, playgrounds facilitate interactions across diverse backgrounds, fostering inclusivity and cultural understanding.

Cognitive Stimulation

Beyond physical activity, playgrounds provide valuable cognitive stimulation. Imaginative play nurtures creativity and divergent thinking as children invent scenarios and role-play different roles. Navigating playground equipment enhances spatial reasoning and problem-solving skills. By experimenting with cause and effect, children learn valuable lessons about risk-taking and decision-making.

Safety Measures

While playgrounds offer numerous benefits, safety remains paramount. Proper surfacing materials, such as rubber mulch or synthetic turf, cushion falls and reduce injuries. Regular maintenance ensures equipment remains safe and functional, while supervision by caregivers promotes responsible play. Furthermore, inclusive design principles accommodate children of all abilities, creating a welcoming environment for everyone.

Community Engagement

Playgrounds serve as focal points for community engagement, fostering social connections among families. They provide opportunities for parents to interact while their children play, strengthening neighbourhood bonds. Community-led initiatives, such as volunteer clean-up efforts or fundraising for new equipment, promote a sense of ownership and pride in local parks.

Playgrounds are indispensable for children’s development, offering a multifaceted approach to physical, social, and cognitive growth. By providing safe and stimulating environments for play, communities can nurture the next generation of healthy, empathetic, and creative individuals. Recognizing the importance of outdoor play in a digital age, investing in playgrounds becomes essential for building resilient and thriving communities. Through collaboration and commitment, we can ensure that playgrounds remain vibrant spaces where children can thrive and flourish.
