Intelligence, Executive Function, and Violence
Intelligence, Executive Function, and Violence
In our first substantive chapter, we provide a comprehensive review of studies that have tested associations between indicators of intelligence (broadly construed to include executive functions and other cognitive measures) and physical aggression or violence. This includes studies of verbal ability, performance intelligence, and the PIQ > VIQ discrepancy. We found that there is much evidence indicating that violent offenders have greater intelligence and executive functioning deficits than nonviolent offenders do, and we were surprised to find that it is unclear whether intellectual deficits are associated with nonviolent-only offending at all. We conclude that measures of intelligence and executive functioning are differentially associated with violent behavior.
