Document Summary
Aggression: any behavior aimed at causing either physical or psychological pain: hostile aggression: behavior intended to harm another, either physically or psychologically, and motivated by feelings of anger and hostility. Instrumental aggression: behavior intended to harm another in the service of motives of other than pure hostility (e. g. , to attract attention, to acquire wealth, or to advance political and ideological causes). E. g. , some of the genocide in rwanda was committed in the pursuit of political. Higher temperatures are related to higher rates of aggression. More violent crimes occur in summer months. More acts of violence occur in cities that have higher average temperature. One study found that baseball pitchers are more likely to hit batters with the ball, as the weather gets hotter. Anger literally raises the temperature of the body because of increases in blood pressure and the distribution of blood to certain parts of the body (e. g. , hands): media violence. Evidence that media violence can increase aggressive behaviors.
