Abstract:The Raven Progressive Matrices tests of 89 hospitalized, chronic schizophrenic males were scored for atypical and avoidable reasoning errors. A total error score on the Bender Gestalt was also computed for each S. Total error score on the Bender correlated .41 and .01 with atypical and avoidable errors respectively. The two Raven error indices correlated –.41. Thus, atypical errors may be assessing the influences of psychopathology on the Raven's perceptual spatial factor while avoidable errors may be reflecti… Show more
