Biological influences:Certain brain areas, when electrically stimulated, can increase aggressive behavior in monkeys. The amygdala in humans is the brain structure which has been linked to aggressive behavior. Aggressive behavior is genetically influenced:By selective breeding, aggressive and passive strains of mice can be created (Lagerspetz, 1979) Blood chemistry can contribute to aggressive behavior. Alcohol can contribute to aggressive behavior bydecreasing self-awareness (deindividuation factor), and decreasing the ability to accurately perceive the outcome of an aggressive act. Low blood sugar levels can boost aggressiveness. Testosterone:Males with high testosterone levels are more prone to delinquency, hard drug use, and aggressive responses when provoked. Psychological Influences of Aggressive BehaviorFrustration: the blocking of goal-directed behavior. The frustration-aggression theory (1939) : Frustration creates a motive for aggression. Fear of punishment or disapproval may cause the aggressive behavior to be displaced against some other target, or oneself. However, the frustration-aggression theory overstated the link. Frustration that arises from an understandable cause does not necessarily lead to aggressive behavior.
