Frustration is anything that prevents us from achieving a goal. This theory has contradictory results: sometimes frustration increased aggressiveness and sometimes not. Justifiable frustration remains frustrating but triggers less aggression than a frustration we perceive as unjustified.
The basic postulates suggest that many people have learned to respond to their frustrations in a non-aggressive way. The initial experience of anger can be intensified, enriched, differentiated, reduced or completely eliminated if people activate thoughts, feelings, conceptions and social norms about emotions and behaviors that would be appropriate in certain circumstances.
