However, the test requires the subject to shift set, to follow rules, and to keep a record of previous responses so that actions are not repeated. Palmer, Dawes, and Heaton offer a broad historical view, highlighting the role neuropsychological research has played in crystallizing modern thinking about schizophrenia.
Conscious Unconscious The Wisconsin Card Sorting Test is widely regarded as a specific test of set shifting and patients with schizophrenia do poorly on it as do those with frontal lobe lesions. Difficulties in selecting relevant stimuli for further processing selective attention or filtering have been invoked to explain some positive symptoms like perceptual abnormalities hallucinations and, perhaps, ideas of reference.
