- abnormality: biological approach
- abnormality is an effect of a physical issue in the body, thus abnormality is an illness or disease
- reasons for abnormality:
- genetics
- some people may be genetically prone to developing mental disorders e.g. chance of schizophrenia increases if parent has it. even more so for twins
- brain damage
- abnormal behavior can occur from brain damage; e.g. Alzheimer's is a loss of brain cells and brain function
- infection
- infection can lead to mental illness, e.g. if syphillis goes untreated it can develop to psychosis
- biochemistry
- an imbalance of chemicals in the brain can cause abnormal behaviour; e.g. depression is linked to a lack of seretonin
- genetics
- positive evaluation
- scientific evidence: based on well established proven scientific principles, very accurate and reliable research. cannot be biased.
- explains many disorders: many disoreders understood by rhe medical model: e.g. schizophrenia by genetics
- negative evaluation:
- reductionist: gives one simple explanation to something much more complex, it says biology cannot account for abnormal behavior and this must be learnt
- underlying causes; we cannot prove if biological differences are cause or result of abnormal behaviour
