This essay will evaluate biological and psychological theories of aggression and associated methods of its reduction and control. It will assess the influence of the media on pro and anti-social behaviour identifying individual, social and cultural diversity in aggressive and pro social behaviours.

The distinction between these two types of aggression is not always clear as they may be a range of other biological, social and environmental factors motivating the aggressive behaviour. There are also different theories of aggression which include biological, physiological, instinct, learning and environmental theories. A biological theory of aggression suggests that it is caused due to high levels of testosterone and Floody (1983) found that hormonal changes in women can produce aggressive behaviour. Physiological theories suggests that there are genetic causes of aggression and research says that the possession of an extra ‘Y’ chromosome can make men more aggressive. Instinct theories suggest that aggression is important in the evolutionary development, allowing individuals to adapt to their environment and survive in it. They suggest ‘aggressiveness is clearly important in competing successfully
