Evaluation

• Research support for the role of central control


  • Bratt - Sensory Gating
  • Paired-click method - schizophrenic parents unable to 'gate-out' subsequent, irrelevant stimuli
  • May explain perceptual overload many schizophrenics report
• Proximal explanation


  • Cognitive explanation only explains proximal origins of symptoms
  • Doesn't offer distal explanations like genetics and family dysfunction do
  • Therefore, partial explanation
• Research support for the cognitive model of schizophrenia


  • Sarin and Wallin
  • Positive symptoms - faulty cognition
  • Biases - no reality testing, jumping to conclusions
