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
There are many reinforcement models that have been defined including the classical conditioning model. This model defines addiction as a behavior that is repeated because of the attention given associated with its reinforcement. An example of where this theory is used is when Pavlov rung the bell to his dog and gave the dog food, the dog then learnt when the bell rang he would be rewarded, this could be used as an explanation to addiction. When the drug user takes the drug they are rewarded as they get a ‘high’ this is the same kind of thing as Pavlov’s dog as the drug is the stimulus as was the bell to his dog and the ‘high’ being a reward as was the food to the dog. Pavlov’s dog had be conditioned to believe that when the bell rang he would be given a reward, so as a drug user you would tend to believe that if you take the drug you are rewarded which could lead to addiction.

The Biological and conditioning theory contrast as the biological theory believes addiction is within genetics and the conditioning theory believes that addiction is within positive and negative reinforcement on drug abuse.

Aggression is thought to be learnt from surrounding people’s actions and imitating them according to the social learning theory which has been previously explained. However the biological theory suggests that all aggression comes from genetics, this could be because one or both parents have not had enough dopamine in
