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.

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. More fundamentally, they believe that differences in intellectual ability are a product of social inequalities in access to material resources and opportunities.Nature vs.

Nurture in Psychology By Saul McLeod, updated The nature vs. nurture debate within psychology is concerned with the extent to which particular aspects of behavior are a product of either inherited (i.e., genetic) or acquired (i.e., learned) characteristics.

The nature versus nurture debate is about the relative importance of an individual's innate qualities ("nature", i.e. nativism, or philosophical empiricism, innatism) versus personal experiences ("nurture") in determining individual differences in physical and behavioral traits.
