A strength of the biological model is that it is empirical Experiments used are measurable objective and can be replicated to provide reliable evidence, the person carrying out the experiments also has control over the variables. Another strength is that it is deterministic it provides an explanation for the cause of a behaviour or symptom increasing the likelihood of effective treatment.
A weakness of the biological model is that it focuses only on the physical causes and takes no account of environmental or other factors. Another weakness is that it takes no account that everyone is an individual and generalises disorders to fit everyone (Eysenck and Eysenck, 2005).
Treatments associated with the biological model are aimed at treating physiological processes most common of these are drug therapy’s the use of medications that influence the functions of the brain for example antipsychotic drugs act by blocking the action of neurotransmitters in the brain or antidepressants work in different ways to increase the levels of …show more content…
Physical manifestations of mental illness (behaviours) result from conflict between the id the most primitive part of the personality seeking instant gratification. The ego the conscious rational part of the personality and the superego the sense of right and wrong.
