Fraisse's theory of emotion and aggression.

This article shows how Fraisse's (1964) theory of emotion is a better explanation of aggression than any other theory of emotion. It discusses conceptual and methodological difficulties in existing theories of aggression and reports a study that supports a hypothesis based on Fraisse's theory. This study, which used Canadian university students equally divided by sex, supports the hypothesis that subjects would be more aggressive when faced with an unexpected annoyance than with an expected annoyance. Aggression was indexed by subjects' evaluation of the target person (confederate) as a source of annoyance.
