The effects of token reinforcement and feedback on the delusional verbal behavior of chronic paranoid schizophrenics.

Prior research with token reinforcement in the psychiatric population has been directed at work adjustment, more than at major symptomatic behaviors. The purpose of the present research, on the other hand, was to investigate the effects of feedback and token reinforcement on the modification of delusional verbal behavior in chronic psychotics. Six male and four female paranoid schizophrenic patients participated in the study. The results indicated that the effects of feedback were effective about half the time in reducing percentage delusional talk, but in at least three cases produced adverse reactions. Token reinforcement, however, showed more consistency and reduced the percentage of delusional verbal behavior in seven of the nine subjects exposed to this procedure. The effects of both feedback and token reinforcement were quite specific to the environment in which they were applied and showed little generalization to other situations. It would appear that using token reinforcement can reduce the percentage delusional speech of chronic paranoid schizophrenics.

Reinforcement of competing behavior during extinction.

Conditioned behavior declines in frequency when reinforcement is discontinued. In two experiments this extinction process was facilitated when competing behavior was reinforced as the original response was extinguished. When reinforcement for competing behavior was withdrawn, however, rats resumed their original behavior and there were no overall savings in total responses to extinction.
