Nature Versus Nurture

QUICK REVIEW:

Do our traits and behaviors result from heredity (nature) or the environment (nurture)?

nature vs nurt

The scientific study of biological, cognitive, social, and personality development throughout the life span

The Nature-Nurture Debate:

Nature refers to the influence of genes which we inherit

Nurture refers to environmental influences, such as:

  health and diet of the embryo’s mother
–  family
–  school
–   community
–   society

Raising the issue of:

  • Environmental causes of behavior (the influence of parents, siblings, friends, schooling, nutrition and other experiences)
  • Hereditary causes of behavior (those based on the genetic makeup of an individual that influence growth and development throughout life).

A major issue in developmental psychology is the nature-versus-nurture question

Psychologists today agree that both nature and nurture interact to produce specific developmental EQUALpatterns and outcomes. The question has evolved into how and to what degree do environment and heredity both produce their results?

Genetics = Nature

  • Developmental psychologists agree that genetic factors not only provide the potential for particular behaviors or traits to emerge, but also place limitations on the emergence of such behavior or traits:
  • Heredity defines people’s general level of intelligence, setting an upper limit that people cannot exceed.
  • Heredity also places limits on physical abilities.

Environment = Nurture

  • Developmental psychologists  agree that in most instances environmental factors play a critical role in enabling people to reach the potential capabilities that their background makes possible.
  • Heredity defines people’s general level of intelligence, setting an upper limit that people cannot exceed.
  • Heredity also places limits on physical abilities.

NATURE NURTURE

Behavioral GeneticsNATURE

  • While a few psychologists believe that development is only nature or only nurture, most subscribe to the more realistic view that it is an interaction of nature (heredity) and nurture (environment) that brings about our development.

 

 

If Albert Einstein had received no intellectual stimulation as a child and had not been sent to school, it is unlikely that he would have reached his genetic potential???
