Impairment in abstract conceptualization and Bannister and Fransella's grid test of schizophrenic thought disorder.

Hypothesized that measures of thought disorder derived from D. Bannister and F. Fransella's (see record 1966-10277-001) theory and from an earlier theory would covary in a sample of 38 male psychiatric inpatients not initially diagnosed as schizophrenics. Ss were administered Part II of the Object Sorting Task and Bannister and Fransella's grid test of schizophrenic thought disorder. Results support the hypothesis that the recently developed grid measures are related to earlier theories which consider impairment in abstract conceptualization the hallmark of schizophrenic thought disorder.
