Evaluation of Biological Explanations of Schizophrenia

The biological explanation of schizoprenia is deterministic

• True

• False

A strength of the fact the biological approach is deterministic is:

• It allows cause and effect relationships to be investigated

• It is empirical

• It considers multiple factors

The biological approach to explaining schizophrenia is idiographic:

• True

• False

The biological explanation of schizophrenia is nomothetic, this is a limitation because:

• it takes individual circumstances into consideration too much, meaning it lacks scientific credibility

• It has created general rules about the cause of schizophrenia, which mean treatments have been developed which can treat the majority of patients.

The genetic explanation of schizophrenia may be supported by incomplete evidence

• True

• False

One strength of the serotonin hypothesis (as a neural correlate) is that it led to the development of anti-psychotic medication which reduces the level of serotonin in parts of the brain:

• True

• False

The neural correlates explanation of schizophrenia is based on the idea that certain abnormalities in the brain cause schizophrenia:

• True

• False

Abnormalities in the pre-frontal cortex are associated with:

• Catatonic behaviours

• Avolition and speech difficulties

• Delusions and disorganised thoughts
