key adoption study!

• what is the key adoption study?!

  leve et al.
• leve - aim/focus.


  to see how adoptive parents treat inherited characteristics of adoptive children.
• leve - sample.


  sample of 360 adoptive triads - adoptive child, adoptive parents and biological parents. done over 10 different states.
• leve - procedure.


  looked at child's behaviour in terms of factors like school performance, social ability and ability to express emotion or concern.
• leve - findings. 


  found as early as age 2 and a half a child can show precursors to aggression. also found that mums had much more influence on the child's ability to regulate their emotions than their dad - suggest environmental influence and nurture debate.
• leve - g.


  adoptive child so difficult and busy life - may have had other adoptive families that gave them back. but done across 10 states and is a large sample!
• leve - r.


  yes very replicable. risk of researcher bias as they may observe something more or less aggressive.
• leve - a.


  identifying aggression early in childhood to prevent it from worsening and become life impacting.
• leve - v.


  natural experiment so ecologically valid. lack of internal validity as no iv is being manipulated however. researcher/social desirability bias.
• leve - e.


  fairly ethical but socially sensitive as it involves participation of biological parents (reasons why they left them like addiction etc).
