Document Summary

Aggression- physical or verbal behaviour intended to hurt someone (not a painful dentist visit) Hostile aggression- aggression driven by anger and performed as an end in itself (goal = to injure/kill) Instrumental aggression- aggression that is a means to some other end (terrorism) Freud thought aggression was self-destructive, konrad lrenz thought adaptive, but both agreed it was instinctive- an innate, unlearned behaviour pattern exhibited by all members of a species. No one area of brain, but stimulating or destimulating certain areas (like amygdala) have influence. Breeding dogs for aggression/ identical twins have similar criminal records. Intoxicated people administer stronger shocks: assailants often have been drinking, linked with violent behaviour. Reduces self awareness: testosterone, diminish testosterone, aggressive tendencies subdued, after age 25, both testosterone and violence decrease, handling a gun increases testosterone levels, high testosterone levels linked with delinquency, low serotonin, low levels linked with violence.
