15.2.2 Adoption Studies

    Cards (15)

    • What is the primary purpose of adoption studies in understanding behavior?
      Separate genetic and environmental influences
    • Unlike twin studies, adoption studies focus on individuals raised apart from their biological parents
    • Adoptees share high genetic overlap with their biological parents but low environmental overlap.
    • Match the steps in the methodology of adoption studies with their descriptions:
      Data Collection ↔️ Gather aggression data from adoptees and their families
      Comparative Analysis ↔️ Compare aggression levels between adoptees and biological parents
      Statistical Analysis ↔️ Quantify correlations using statistical methods
    • What is one benefit of adoption studies in understanding aggression?
      Separating genetic and environmental influences
    • Adoption studies allow researchers to assess genetic contributions independently of shared environments.
    • When adoptees share a low environment with their adoptive parents, it suggests that environment influences their behavior.
    • High aggression similarity between adoptees and biological parents indicates a genetic influence.
    • Order the factors that influence adoptee aggression based on shared genes and environment:
      1️⃣ Shared Genes: High, Shared Environment: Low (Biological Parents)
      2️⃣ Shared Genes: Low, Shared Environment: High (Adoptive Parents)
    • What does genetic predisposition refer to in adoption studies on aggression?
      Likelihood of aggressive behavior due to genes
    • A supportive adoptive environment can mitigate genetic tendencies toward aggression.
    • Adoption studies focus on individuals raised apart from their biological parents.
    • What role does genetic predisposition play in aggression according to adoption studies?
      Increases likelihood of aggressive behavior
    • A supportive adoptive environment can mitigate genetic tendencies toward aggression.
    • Match the strengths and limitations of adoption studies:
      Strengths ↔️ Clear separation of genetic and environmental influences
      Limitations ↔️ Incomplete genetic history of biological parents
