Conclusions

• what do the findings suggest when considered alongside previous finding?

  • past research identified links between areas of the brain and violence
  • findings supported by this study
  • together these findings provide preliminary evidence that murderers pleading NGRI have different brain functioning to normal indivs
• why do the findings need to be understood with caution?

  • neural processes underlying violence are complex and cant be reduced to a single brain mechanism
  • violent behaviour probably best explained by disruption of network of interacting brain mechanisms rather than single structure
  • such disruption wouldn't cause violent behaviour but would predispose indiv to violent behaviour
