Nature versus Nurture How much does nature/nurture play into behavioral traits in children? DF Analysis aims to answer the “how much” question
Study 1 • Focused on height and weight of the subjects participating • Studies concluded that height and weight are both highly heritable
Study 2 • Tested following traits: antisocialism, anxiousness, headstrongness, hyperactivity, dependency and proneness to peer conflict • The researchers determined that antisocial and headstrong behavior is highly influenced by environmental factors • anxiety and hyperactivity are more heritable and less sensitive to environmental factors • studies also determined that kin pairs spanked the most had the highest levels of behavioral problems, in particular antisocial and headstrong tendencies
Critical Review • 1) Bad information may have been obtained which could alter the legitimacy of the data collected. Perhaps, parents not knowing their children as well as they should • 2) Researchers were able to account for many different age ranges and were able to assess twins, siblings, half siblings, and cousins which helps measure the heritability of a trait • 3) The HOME observation is a good measurement because it accounts for the mother and child’s rating of the home environment.
