Individual Differences Evaluation - Cognitive Approach

Question 1

Evaluate supporting research…

Answer 1

Cognitive models and theories led to tremendous amounts of scientific research being conducted

Deanna Barch et al (1999) compared performance between schizophrenics and non-schizophrenics on the Stroop test, were those with schizophrenia were slower

Evidence that those with schizophrenia couldn’t filter information as effectively, supporting the theory that their attentional filters are defective

Question 2

Evaluate the approach’s reductionist effect…

Answer 2

Proposes that faulty cognitive mechanisms are due to disconnections in functions within the frontal cortex

Some evidence by detecting changes in blood flow in the brains of schizophrenics and non-schizophrenics

Reductionist as it reduces a complex experience to the functioning of brain circuits

Question 3

Evaluate how the approach is not a comprehensive theory…

Answer 3

Only able to explain cognitive symptoms, as only cognitive deficits that underline symptoms are explained, not their origins

We should be cautious about the claims made as a single explanation for schizophrenia

Question 4

Evaluate the approach’s integrated model of schizophrenia…

Answer 4

Approach is important but psychologists are realising that a holistic approach is necessary

Oliver Howes and Robin Murray (2014) integrated model that genes, life events, social stresses and certain aspects of early life combine, provoking dopamine system into releasing dopamine

Causes issues with cognitive processing, as individuals are caught in a cycle, where symptoms cause the release of dopamine and vice verse, suggesting that the approach alone is insufficient
