The Progressive Matrices (1938) With Chronic Brain Disorder And Chronic Schizophrenic Subjects, Ellis L. Schultz
Student Work
This is a report of a study which investigated the performance of two experimental groups of adult psychiatric patients and one group of noninstltutional control subjects on Sets A, B, C, D, and E of the 1956 revised edition of the Ravens Progressive Matrices (1938 Fora, referred to throughout this paper as the PM). The two experimental subject groups consisted of a chronic schizophrenic reaction group and a chronic brain disorder without-psychosis group.
