Document Summary
Aggression: physical or verbal behaviour intended to hurt someone. Animals exhibit (1) social aggression which displays rage and (2) silent aggression which is when a predator stalks its prey. Hostile aggression: aggression driven by anger and performed as an end in itself: purpose is to injure. Instrumental aggression: aggression that is a means to some other end: also to injure but only as a means to some other end, ex) terrorism. In analyzing causes of hostile and instrumental aggression, social psychologists have focused on three big ideas: biological influences, frustration, and learned behaviour. Freud human aggression springs from a self-destructive impulse. Lorenz aggression is adaptive rather than self-destructive. Instinctive behaviour: an innate, unlearned behaviour pattern exhibited by all members of a species. Instinct theory fails to account for the variation in aggressiveness, from person to person and culture to culture. Although aggression is biologically influenced, the human propensity to aggress does not qualify as instinctive behaviour.
