Aggression stems from many genetic, environmental, and situational factors operating together. Frustration and provocation can elicit aggression, as can heightened arousal and exposure to media violence. Aggression is also influenced by personal traits like sensation seeking and gender, with males tending to be more aggressive overall. Bullying involves repeated aggression against vulnerable individuals, while workplace aggression is often covert rather than overt. Punishment can reduce aggression when delivered appropriately, and techniques like forgiveness may also help if used carefully.
