  1. Nature vs. Nurture

  2. Nature vs. Nurture • Is everything we do based on genetics (nature) or the environment (nurture)? • Is who we are determined when we are born (genetics) or does it depend on how we are raised (the environment)? • B.F. Skinner vs. Darwin

  3. Darwin- Nature • 46 chromosomes (23 pairs) • DNA • Recessive vs. Dominant • Genetics- how people/plants pass traits from one generation to generation

  4. Family Studies • Def: researchers assess heredity (genetic) influence by examining blood relatives to see how much they resemble one another on a specific trait • 50% shared each trait with siblings and parents • The more genes that are shared, the more similarity there should be • Families also share environments – so it’s difficult to know if it is primarily a result of genetics or the environment

  5. Twin Studies • Def: researchers assess heredity influence by comparing the resemblance of identical (genetically the same) twins and fraternal (non-identical) twins with respect to a trait • Identical twins: • 87% correlation of intelligence • Raised in the same environment • Not possible to split them up and put them in different environments (ETHICS!)

  6. Adoption Studies • Def: assess heredity (genetic) influence by examining the resemblance between adopted children and both their biological and their adoptive parents • If they are more similar to their biological parents, the traits are probably due to genetics • If they are more similar to their adoptive parents, the traits are probably due to the environment

  7. Chromosomal Abnormalities • Man determines sex of baby • XX = Girl, XY = Boy • Turner syndrome- 1 single x chromosome: affects females = causes physical shortness and often ovaries do not function • Klinefelter syndrome- extra X chromosome: affects males = infertility / small testicles

  8. Down Syndrome • Down Syndrome- = extra chromosome 21 • Individuals with down syndrome have distinct facial features
