Biological Explanations for Schizophrenia.
The psychodynamic explanation Freud believed that schizophrenia is caused by issues in the sub-conscious mind of the schizophrenic. If someone experiences something particularly harsh they may regress to a childlike state, before the ego was fully formed. This childlike state is what brings about the symptoms; delusions, grandeur etc.
Evaluation of the psychodynamic explanation The only real strength of the psychodynamic explanation is that it has face validity; the symptoms of schizophrenia do seem similar to some childlike behaviour.
This is partly because the theory is based upon abstract ideas such as dreams and the subconscious. The cognitive explanation This explanation says the schizophrenia is caused by faulty thought processing. So, due to faulty processing, the simple problem of mistaking something unreal for something real has lead eventually to paranoia.
Instead it builds on the biological model, and offers an explanation on how the problems can develop into schizophrenia. Evaluation of the cognitive explanation of schizophrenia There is a wealth of research evidence to back up the cognitive explanation.
For example, Meyer and Lindenberg found a link between excess dopamine in the prefrontal cortex, and the state of working memory. This suggests that there is a scientifically proven link between faulty processing, and high dopamine levels.
This supports the connection between the biological and cognitive explanations. Another strength of this explanation is that it allows us to develop treatments.
For example, Yellowlees et al created a machine that creates virtual hallucinations, the sort that a schizophrenic might experience. The aim of this machine is show schizophrenics that their hallucinations are not real. Whilst there is little evidence that this will work, it has only been possible because of the cognitive explanation.Aug 20, · MCAT topics list by Gold Standard MCAT to guide students on what to study for the exam.
