Nature vs Nurture

1
Nature vs Nurture

• The Great Debate

2
The Debate

• Examines the influences of genetics and heredity
  (nature) as well as the impact of environment
  (nurture) on the development of individual people

3
Nature or Nurture?

• Two factors were previously thought to be
  separate
• Now, researchers are focusing on how each one
  jointly impacts growth and development

4
Heredity and Genetics

• Passed onto offspring by parents
• Impact a person's behaviour patterns
• Think about the ways in which you are
• similar to your parents?

5
Nurture - Environment

• Consists mainly of the people around us
• What other factors could be considered nurture?
• Parental influence is a major contributor to the
  nurture aspect of the debate and is seen as a
  central influence on a child's development and
  behaviour

6
Conclusion

• A person's behaviour develops with
• influence from both their natural being (heredity
  and genetics) AND their nurtured
• environment

Twin Studies

• What can twins who were raised apart tell us
  about the effects of nurture and nature?

Twins

• When identical twins are brought up apart from
  one another, they are more similar to each other
  than two random people might be -- that's because
  they share genes but not environment.
• If those same twins are brought up in the same
  home with the same parents, they are more alike
  than are fraternal twins brought up together.

Feral Children

• What can cases of children raised without
  nurturing tell us about the effects of nature and
  nurture?

Feral Children

• Everything we know about being human, we learn
  from the people around us
• The brain develops differently when children are
  not nurtured (smaller, more dark spaces)
• Development is extremely delayed in all areas
  when children are isolated
• Genetics gives us a brain but children need to be
  nurtured in order to learn and develop
