- Cognitive explanations
- Outline (A01)
- Abnormalities in cognitive functioning lead to dysfunctional beliefs and delusions
- Defective filters let in too much irrelevant information
- Inundated with external stimuli; cannot interpret the world appropriately
- Research evidence
- Stirling et al (2006) Schizophrenic patients took twice as long to complete the stroop test
- Frith (1992) Disorganised speech and thought disorder comes from poor central control
- Central control; ability to suppress automatic responses and replace with deliberate actions
- Evaluate (A03)
- Too reductionist; ignores any other basis
- Practical applications; CBT shows treatments using cognitive explanations are effective
- Accounts for both positive (delusions) and negative (speech poverty) symptoms
- Manschreck (1970) Delusions occur in a variety of disorders where no cognitive impaitment is evident
