The issue of whether or not criminal or aggressive behavior and violence is caused by biological or environmental factors has proven to be one that has caused a dispute for many years now. The biological or genetic factor of violent/criminal or aggressive behavior is certainly a much talked about topic. The idea that certain individuals could be predisposed to violence is something definitely deserving of doing research about. The nature vs. nurture topic has been a continuing debate for many aspects of human behavior, including aggression/violent behavior and criminal behavior. There have been many studies indicating that chemical relationships between hormones and the frontal lobe of the brain may play a key role in determining …show more content…
We are subject to social influences from the moment we are conceived and these influences only increase over the years. The influence of social contact happens so gradually and to some extent unconsciously, we don’t really notice.
Although criminal aggression is difficult to define precisely for research an overall definition for aggressive/violent behavior is that aggression and violence refers to any behavior that is hostile and destructive. Generally, aggressive behavior involves physical force with the potential to inflict hurt, damage or kill the target person or object. Aggression as a learned behavior (nurture) comes from studies of behavior in experimental and natural settings, social learning theory and the effect of cultural and social variables. Biological theories (nature) propose that aggression may have a chemical, hormonal or genetic component. (Colt). Scientists have explored a range of possibilities of behavior. Some of the most compelling evidence comes from genetics, serotonin research and the influence of hormones on aggression. According to Cloninger he says, "It's silly to think that genes specifically could be the cause for aggressive or criminal behavior, but there are gene products that can be influenced by the environmental setting and social learning and that indirectly influence some people to aggression."(Bower).
In 1930s, The Eugenics Movement was fueled partially by a desire to get rid of habitual
