Performance of schizophrenic patients on a motor-free visual perception test.
The Motor-Free Visual Perception Test (MVPT) was administered to 15 chronic schizophrenic patients and 15 normal controls, ages 40 to 60, to see whether, perceptual deficits would be found on non-motor tasks. Groups significantly affected performance on the MVPT, as did occupational status. In the schizophrenic group only, efficiency of intellectual functioning was positively related to how well they performed on the MVPT. Age, educational level, and IQ had no significant impact on functioning on this test in either group. The schizophrenic patients made more errors on the more complex operations of the MVPT, and the only significant group differences in percentage of subjects' own errors was in figure-ground. The MVPT may be useful in screening for visual-perceptual deficits in adult schizophrenic patients.
