Extract

Studies using objective tests have found that two relatively independent types of thought disorder occur in patients diagnosed as “schizophrenic”. In several studies (Payne, 1961) approximately half the acute schizophrenic patients showed an extreme degree of intellectual and motor retardation, more severe than that found even among retarded depressed patients, while half suffered from overinclusive thinking, as measured by the tests used. There was a significant tendency in one study (Payne and Hewlett, 1960) for these two types of thought disorder not to occur in the same acute schizophrenic patients.
