Biologists stressed the role of genes in controlling the development of living things, while psychologists and sociologists investigated the impact of subjective experience and the social milieu upon individuals. Each discipline found convincing evidence for its view and concluded that the other approach was mistaken. He maintains that recent studies demonstrating how the environment affects the ways in which genes are expressed, combined with data showing how genes influence behavior, provide an understanding of how heredity and environment actually cooperate in producing human behavior.
By Saul McLeodupdated The nature vs. 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.
The nature-nurture debate is concerned with the relative contribution that both influences make to human behavior. Nature Nurture Debate in Psychology It has long been known that certain physical characteristics are biologically determined by genetic inheritance.
Other physical characteristics, if not determined, appear to be at least strongly influenced by the genetic make-up of our biological parents. Height, weight, hair loss in menlife expectancy and vulnerability to specific illnesses e.
Those who adopt an extreme hereditary position are known as nativists. In general, the earlier a particular ability appears, the more likely it is to be under the influence of genetic factors. Characteristics and differences that are not observable at birth, but which emerge later in life, are regarded as the product of maturation.
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 infancylanguage acquisition and even cognitive development as a whole.
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, when an infant forms an attachment it is responding to the love and attention it has received, language comes from imitating the speech of others, and cognitive development depends on the degree of stimulation in the environment and, more broadly, on the civilization within which the child is reared.
Likewise, Chomsky proposed language is gained through the use of an innate language acquisition device. This is seen in his famous Bobo doll experiment Bandura, Also, Skinner believed that language is learnt from other people via behavior shaping techniques.
In practice, hardly anyone today accepts either of the extreme positions. This question was first framed by Francis Galton in the late 19th century. This view has cropped up time and again in the history of psychology and has stimulated much of the research into intelligence testing particularly on separated twins and adopted children.
A modern proponent is the American psychologist Arthur Jenson. Finding that the average I.
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. Today in Britain many believe that the immigration policies are designed to discriminate against Black and Asian ethnic groups.
However the most chilling of all implications drawn from this view of the natural superiority of one race over another took place in the concentration camps of Nazi Germany.
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.The nature versus nurture debate revolves around the contributions of genetic factors and environmental factors to human development.
The primary method of attempting to determine which of these effects human development the most has been cross-cultural studies. In the context of the nature vs. nurture debate, “nature” refers to biological/genetic predispositions’ impact on human traits, and nurture describes the influence of .

Ridley rejects the premise that human nature is primarily determined either by genetic inheritance or by environmental influences. He argues that nature and nurture are not competitors but. The nature versus nurture debate is about the relative influence of an individual's innate attributes as opposed to the experiences from the environment one is brought up in, in determining individual differences in physical and behavioral traits.
