evaluation cognitive approach

• supporting research

  • Frith - loads of scientific research
  • Barch et al - stroop test, found that people with schiz were slower and made more mistakes
  • couldn't filter information properly
• Reductionist

  • reduces complex experiences to the functioning of brain circuits
  • Frith, faulty operation of cognitive mechanism is due to disconnection of functions in the frontal cortex and some evidence for the cerebral blood flow when completing cognitive tasks
• Not a comprehensive theory

  • only able to explain cognitive symptoms
  • issues of movement symptoms are not explained well
  • criticised for only describing cognitive deficits thought to underline symptoms but do not always explain origins of the deficits
• integrated model of schizophrenia

  • needs to be considered in a more holistic way and include cognitive factors
  • howes and murray 2014 - have described an integrated model of schiz suggesting genes and life event provokes dopamine system to relate dopamine which causes hallucinations
