Leading Proponent: Konrad Lorenz (ethology)
He says we have a biological need for aggression. It gets stronger as time passes since the last aggressive act (like hunger increases hours after a meal).
This causes our energy level (drive level) to increase. This energy must somehow be released (“catharsis”).
Instinct Theory: Through evolution, humans have inherited a fighting instinct similar to that found in many species of animals.
Instinct Theory says that humans learn their own individual ways of expressing aggressive motivation. Nonhuman species behave in ways that are genetically programmed and characteristic of all members of the species.
Fixed Action Pattern: complex behavior that is largely unlearned and found in all members of a species (or subgroup), and that is triggered by a very simple stimulus in the environment (“releaser”).
1. Aggression is inevitable - the accumulating energy must find an outlet

Negative Affect Theory: Proposed by Leonard Berkowitz, it states that negative feelings and experiences are the main cause of anger and angry aggression. Sources of anger include: pain, frustration, loud noise, foul odors, crowding, sadness, and depression.
The likelihood that an angry person will act aggressively depends on his or her interpretation of the motives of the people involved.
