Sorting consistency as a diagnostic tool for schizophrenics and normals.

ABSTRACT

This report demonstrates the potential of the Sorting Consistency Task, both for assessing the degree of schizophrenic disturbance in patients, and for screening normals for schizophrenic tendencies. The task can be administered quickly and adapted for individual or group testing. Experiment 1 demonstrated a strong relationship between the Sorting Consistency Task and indicators of schizophrenic disturbance. Experiment 2 used normals and demonstrated that the Sorting Consistency Task could discriminate between subjects who score high or low on the Physical Anhedonia Scale of Chapman et al. (1976).
