Outline and evaluate the biological approach to psychopathology (24 Marks) Psychopathology is the study of mental distress and abnormal maladaptive behaviour, there are four approaches to psychopathology, cognitive, behavioural, psychodynamic and biological. The biological model of abnormality is split into four parts which can all cause abnormal behaviour these are; Genetic, Brain injury, Neurotransmitters and Infection. It is believed that faulty genes can cause some disorders that have a psychological effect. A way in which this can be tested is by doing studies on twins as they have the similar genetics. McGuffin et al did a study in 1996 where they compared 109 sets of twins in order to investigate how likely each twin was to develop depression. They looked at the concordance rates for depression in MZ and DZ twins, they expected that MZ twins either both have depression or neither have depression. So therefore its expected to find a higher concordance for depression in MZ twins that in DZ twins. The results showed that if one non identical twin developed depression that there was a 20% likelihood that the other would too, in identical twins this rose to 46%. This study therefore proves that genetics can have a massive impact on abnormality. …show more content…

Additionally there is also the fact that we don't know the precise mechanism that is transmitted and without knowing the specific genes that are involved it makes it hard to understand the functions that produce symptoms of
