An Explanation Of An Instinct Theory

Good Essays

Aggression is defined as the intention to cause physical or psychological harm to oneself, an object, or another, in a form that is not socially sanctioned. Aggression can be further subdivided into types of aggression, for example Predatory Aggression- hunting-, Social Aggression- stalking-, and Defensive Aggression- defence of personal practice.
Over time it has been established that there are two umbrella classifications in terms of theories of aggression; Instinct Theories, and Bio-Social Theories. Instinct Theories explain human aggression as solely innate, whereas Bio-Social Theories describe aggression as being innate, with specific stimuli required to trigger it.
One example of an Instinct Theory is the Ethological Approach, …show more content…

This was defined by Lorenz as an adaptive response; aggressive behaviour ensures survival and reproduction.
Lorenz also coined two other laws of aggression; one which was an innate tendency, and another which was not naturally harmful. The former expressed that sometimes aggression was triggered by environmental signals- e.g. the male stickleback fish charging upon seeing the colour red. The latter however, referred to ritualised aggression -which is common in animals, such as wolves, who live in packs- where individuals of a group perform a ritualised display of aggression to solidify their place in the pack, and avoid any real confrontation which could result in severe injury.
Lorenz hypothesised a Hydraulic Model of aggression, implying a need for catharsis. This suggested that channelling aggressive energy into alternate ‘socially-acceptable’ pathways such as exercise would prevent an outburst of harmful aggressive behaviours. However in a study by Zillmann et. Al (1972), it was found that the inverse was true. In Zimmerman’s experiment, the participants were divided into groups; half of which were subject to provocation by a male confederate in order to anger them, and the other half were not. Each sub-group was then further halved; one half enduring intense physical exercise for two-and-a-half minutes, while the other half were subject to a non-arousing task.
