Anger is a common, universally experienced emotion, which occurs on a continuum from mild annoyance to rage or fury (Daffenbacher et al., 1996). Anger is likely to occur when a person believes their personal rights or codes have been violated. Similarly, anger can occur when a person feels powerless or threatened (Horn and Towl, 1997). Anger consists of interrelated, reciprocal components (Novaco, 1975). Environmental circumstances often trigger anger. Physiological symptoms can serve to alert the individual that they are angry, and can help them provide a label to that anger. Cognitions refer to the individual's style of thinking about, or perception of the events. This encompasses their appraisals, attitudes and beliefs. Behaviour is the final component and involves the behavioural reaction in response to the event or the anger itself.
