PSY220H5 Chapter Notes - Chapter 13: Copycat Suicide, John Hinckley Jr., Robert De Niro
Document Summary
Hostile aggression: behaviour intended to harm another, either physically or psychologically, and motivated by feelings of anger and hostility. Instrumental aggression: behaviour intended to harm another in the service of motives other than pure hostility (for example, to acquire wealth, or to advance political and ideological causes). Many acts of aggression involve a mix of instrumental and hostile motives. The right mix of situational factors can give rise to violence. Certain genes may predispose people to aggression, but it is a mix of nature and nurture that ultimately determines how aggressive an individual may become. People have long believed that moods and actions are tied to weather. Most widely assumed, is the connection between heat and aggression. There have been found to be higher rates of crime violence in hotter areas. Also found that people are more violent during the hotter months of the year.
