Aggression - Biological Theory vs Behaviorist Theory Aggression is a problem that affects all members of society. There is no doubt that aggression pays off for some. Parents who yell and threaten punishment get results. The child who hits the hardest gets the toy. The brother who is willing to be the most vicious in a fight wins. The teacher who gives the hardest test and threatens to flunk the most students usually gets the most study time from students. The spouse who threatens to get the maddest gets their way. The male who acts the most macho and aggressive gets the praise of certain groups of males. For decades psychologists have attempted to find the causes of aggression. The focus of this paper will be on the biological as well as the behavioral theory of aggression. The goal being, to better understand the issue of aggression in hopes of gaining some knowledge on dealing with it in a positive manner. Biological theorists suggest that aggression is caused by some genetic or biological factor. Maxon (1998), a leading theorist proposed a theory that one's genes affect one or more types of aggression in mice, which may be applied to humans as a genetic explanation of aggression. Many researchers believe that aggression is caused by some genetic or biological factor, and thus believe that cases involving aggression should be treated chemically. These views of genetic or material essentialism claim that not only are physical characteristics of an individual determined by genetic information, but one's social roles, behaviors, and relationships also have a biological-genetic base (Kegley, 1996). Growing evidence points to the conclusion that biological factors do predispose some individuals toward aggression. Through much research, it was found that people who suffer from reduced levels of serotonin are more likely proned to suffer from reduced abilities to control their aggressive impulses. These findings lend support to the view t...
