criminal behaviour- biological explanations

• What is the role of the amygdala?


  The amygdala is involved in processing emotions such as aggression and fear.
• What did Cocaro et al. find regarding the amygdala and aggression?


  Cocaro et al. found that individuals with LED had high amygdala activity when shown angry faces.
• What did Yu Goo et al. discover about the amygdala and fear conditioning?


  Yu Goo et al. found that dysfunction in the amygdala prevents linking punishment and fear.
• Who first implicated the amygdala in emotion?


  James Papez first implicated emotion and the amygdala.
• What did Rosanof et al. study regarding inherited criminality?


  Rosanof et al. studied 97 twins and found a concordance rate of 67% for MZ twins and 21% for DZ twins.
• What did Cherek et al. find regarding candidate genes and SSRIs?


  Cherek et al. found that SSRIs decrease impulsivity, suggesting MAOA can be a candidate gene.
• What is the diathesis-stress model created by Gottesman and Reilly?


  The diathesis-stress model suggests that genetic predisposition and environmental stressors contribute to the development of disorders.
• What are the biological explanations for inherited criminality?


  • Genetic factors play a role in criminal behavior.
  • Concordance rates in twins indicate heritability.
  • Candidate genes like MAOA are linked to impulsivity.
  • The diathesis-stress model explains the interaction of genetics and environment.
