Verbal Reward & Punishment & Need For Approval In Schizophrenics, Chester Gay Jr.

Masters Theses & Specialist Projects

The current study was designed to further examine the effects of verbal reward and punishment on task performance of schizophrenics. The relationship of need for approval of schizophrenics (as measured by the M-C SDS) to performance and to reward and punishment was also examined.

2. How is the personality construct, need for approval, related to performance of tasks by schizophrenics?
3. Is there a significant interaction between …
