Biological Explanations For Aggression

A range of biological explanations for human onset exists in psychology. One of these is the link between agenttic f titleors and hostility. This explanation claims that competitive behaviour is caused by the genetic science passed down to a several(prenominal)body and that certain genes predispose a soulfulness to be predatory. This consider has support from Sandberg (1961) who identified the XYY karyotype. This is an abnormality in the set of chromosomes gift in in hands- instead of the normal 46 chromosomes men with the XYY gene will demand 47. Court-Brown (1965-67) analysed a sample of 314 infirmary patients and frame that those with the XYY gene were more aggressive than those without it. Furthermore tool studies have supported a genetic basis for aggression (Nelson 2006). all the same it is difficult to generalise the results of these animal studies to vault of heaven as there are significant differences in aggression behaviours between man and animals. Wh ile animals may simply be upon aggressive impulses, humans have linguistic abilities to be up to(p) to communicate with an assaulter more effectively, reasoning skills which allow us to determine whether an aggressive act is the best option, as soundly as empathy to assure how our actions could affect otherwises. Therefore we have the force to not act aggressively even if we are dispose to it.

This highlights another rouge issue: needy will. This theory is rattling deterministic, predicting that if a person possesses a particular gene thusly they will be an aggressive person. However this does not cut in to account free will: we can choose whether ! or not to ladder out an action. Additionally Theilgaard (1984) free-base that genetics are off the beaten track(predicate) more complex and other factors have to be taken into account. Theilgaard examined prisoners with the XYY gene and compared their traits to those with XY gene. Using projective tests, it was found that some XYY prisoners did give the well-nigh aggressive responses, but some also gave the least aggressive. It was then concluded...If you want to get a full essay, order it on our website: OrderCustomPaper.com
