In this part of the assignment the author will explain the contribution of complementary psychological theories to the understanding of two specific behaviours
The two specific behaviours the author has chosen are aggression and addiction. The biological theory on addiction is this theory believes that there are genetic build ups in a person that causes them to react different to addiction, this could mean someone has more of an addictive personality compared to another person. They believe the genetic makeup impact the processing of such chemicals in an individual so they either become addicted easily or not. They believe there is a trigger that in combination with psychological and environmental help causes a person to become addicted easily. There is also evidence to support that addiction can be inherited, or that some individuals may be more likely to developing an addiction than others. Support for this theory comes from twin studies. In these studies, identical twins that were separated at birth (i.e., raised in completely different environments) were found to have similar levels of alcohol levels at different points in their lives. Even though both siblings may have been raised in different alcohol-free homes, they were just as likely to develop alcoholism. Studies have shown that adopted children have rates of alcoholism closer to those of their natural parents than to those of their adoptive parents‘one study found that 30–40 percent of natural children of alcoholics become alcoholics themselves, as opposed to a rate of 10 percent for the general population
