Main Theories of Aggression

Outline and assess the main theories of ill will Aggression is an action of hostility with deliberate intention to harm an otherwise person against his or her will. Some psychologists believe that aggression is an important aspect of our evolutionary linage and it is understood better in that context, whereas others believe that aggression is best explained in physiological terms e. g. the imbalance of hormones or neurotransmitters in the brain. There ar many definitions used to explain why humanitys/ animals become pugnacious (http//www. essortment. com/all/whatisaggress_rxeo. tm). In the social accomplishment guess (SLT) of aggression, Bandura (1962) suggested that the expression of aggression is learnt through social learning non ignoring the fact that the potential for the human aggression was biological. Bandura claimed that we learn specific aggressive demeanours for example, the form in which the aggression takes and how it is addressed to the target. Skinner, 195 3 suggested that a child learns the aggressive doings through lease reinforcement while Bandura argues that a child learns by find parting models indirectly.Moreover, the SLT substructure be used to explain other doingss such as eating disorders, personality etc. Research carried out by Phillip (1986) suggested the day-to-day homicide rate in the US almost increased in the sideline of a major boxing match this suggested that the viewers were imitating the behaviour they watched from their exercise models. This clear shows that the SLT can to a fault be used to explain the behaviour of both the children and adults. This is because aggressive behaviour is witnessed at home and at inculcate as well as through the media i. . reading books, watching goggle box and listening to a certain type of music. By observing the consequences of others actions, children learn the aggressive behaviour indirectly. This whole process is cognise as the vicarious reinforcement whereby a child learns the likely outgrowth of the aggressive behaviour and from that observation they obtain the behaviour that is considered appropriate. Not only when does a child learn the behaviour but the child also observes if the behaviour is worth repeating.In the future, the child is likely to repeat the behaviour when the expectation of a reward is greater than the expectations of being punished (Bandura, 1962). looking for at the Bobo gentlewoman studies, Bandura et al found that children who watched an aggressive model became more(prenominal) aggressive and imitated the behaviour portrayed by the model. This is clear evidence to underpin the SLT for the fact a child learnt the aggressive behaviour by observing the role model.On the other hand, the aggression was imposed towards a doll affecting the reliability of the conclusion because this was a still figure that could not use self-defence. As a ending to this, Bandura repeated the study victimization a film of woman hitting a live clown, thereof this influenced the children to also hit a live clown when given the opportunity. This can explain the cultural differences, for the fact that societies such as the US are highly violent compared to other pygmies of central Africa who manage to live in cooperative friendliness (Aronson, 1999).These findings could be explained by the differences due to social learning whereby the different societies influence the behaviour of the two cultures. However, people also defend differently in term of different situations because aggressive behaviour is rewarded in certain situations than others (i. e. Competitive sports such rugby, boxing etc. ). The appropriate behaviour is learnt for particular situations. Moreover, aggression could also be explained as a result of the loss of personal identity this could be due to the relative anonymity of being in a crowd or wearing a uniform.The Stanford Prison Experiment illustrates this effect this is whereby Zimbardo showed ho w the guards who were deindividuated by mirrored glasses and uniforms extradited precipitously towards the prisoners. The Stanford Prison Experiment is an empirical support for the deindividuated theory because it shows how the behaviour of the commonplace students changed after they had been assigned to adopt the role of guards. However, the brutality could be explained in terms of the perceived social roles because they were not shown the exact way that the material guards behaved.Psychologist Zimbardo believes that deindividuated people are likely to behave aggressively because the loss of a sense in the individual can head up to reduced self- restraint. This in turn leads to impulsive and deviant behaviour and a slight chafe over negative evaluation from others. Being anonymous in a crowd has the psychological consequence of reducing restraints and increasing behaviours that are normally inhibited. Prentice- Dunn and Rogers (1982) suggested that an increase in aggressive behaviour following deindividuation might be caused by the reduced privacy rather than public self- awareness, i. . becoming less self-aware rather than being anonymous to others. A problem for the theory is that deindividuation does not always lead to aggression, and may actually lead to pro-social behaviour. In a meta- analysis of 60 studies of deindividuation, Postmes and Spears (1998) found that deindividuation does not always lead to aggression for example, an individual part of an angry mob is likely to behave aggressively while a member of a peace ricochet is likely to become to peaceful.This clearly shows that frustration leads to aggression. Frustration determines whether aggression is powerful in that situation. Dollard et al (1939) outlined the frustration-aggression theory suggesting that frustration leads to aggression and that aggression is forced by the aggression. Therefore, aggression is the consequence of generalised physiological arousal.
