Cognitive-behavioural perspective
integrates understanding of classical and operant conditioning with cognitive-social perspective.
Cognitive - reflect dysfunctional attitudes, beliefs and cognitive processes
Behavioural - arise from conditioned emotional responses
Biological perspective
root of abnormal behaviour lies within the brain.
- neurotransmitter dysfunction
- abnormality of brain structures
- disrupted neural pathways
- genetics
- diathesis-stress model; underlying vulnerability with symptoms appearing under stress
Systems perspective
root of abnormality lies in the context of a social group (and families). Family systems model; individuals symptoms are viewed as symptoms of dysfunction in the family
Evolutionary perspective
less adaptive behaviour may have its roots in behaviour that is important for survival. important interplay of genes and environment
