key question

• what key question 


  what are implications for society if aggression found to be caused by nature ?
• A01

  • males who get TBI early in life more likely to offend in adulthood suggesting intervention for people who get TBI to prevent crime
  • over 1.6 mil worldwide lose lives to violence a year & leading cause of death for 15-44yr olds which an issue as nature suggests wont change
  • men have 2x odds of TBI than women explaining why more men in prison as biologically more aggressive
  • 60% of young men in prison have some form of TBI suggesting TBI INC criminality so predict reoffending
• A02

  • prefrontal cortex responsible for decision making so if damaged lead to poo decisions leading to aggression without considering consequences
  • amygdala asymmetrical in functioning lead to aggression as impacts emotions, right overactive and left under active then left cant control rights impulsivity
  • testosterone peaks in adolescence & INC social dominance in males supporting males more violent than females
  • evolution suggests males evolved to be stronger to attract mates to pass on genes supporting nature as aggression occurs for drive to reproduce
• A03

  • RAINE found lower activity in prefrontal cortex in NGRI pleaders compared to controls supporting aggression due to nature of irregular brain area function
  • Charles whitman had tumour on limbic system so killed 17 people supporting view that brain/nature responsible for INC violence
  • EISENEGGER found giving females testosterone made behave generously suggests testosterone/nature isnt cause of aggression for both sexes
  • BANDURA says we learn aggression from environment and rolemodels and isnt natural
• balanced conclusion

  • USEFUL -> INC intervention for offenders with TBI in prison to prevent reoffending in future
  • LESS USEFUL -> key question ignored social nurture factors for aggression like bandura so not fully credible for explaining aggression
