Deviations from otherwise reliable patterns of responding in human performance on schedules of reinforcement could be associated with personality characteristics, such as psychometrically-measured schizotypy. The present study examined differences between high and low scorers on four schizotypy subscales (unusual experiences, cognitive disorganisation, introvertive anhedonia and impulsive non-conformity) on a random-ratio (RR) and random-interval (RI) schedule of reinforcement. Results showed a higher rate of responding on the RR than RI schedule, consistent with the differences in performance normally observed between these schedules. However, these differences were dependant on whether or not participants scored high or low on the schizotypy subscales, as well as the specific schedule parameters between the schedules. Specifically, high scorers on the unusual experiences (UE) subscale of the O-LIFE(B) were the only group in Experiment 1 not to show a difference in schedule performance, suggesting high scores on this subscale are linked to altered RR and RI performance. Experiment 2 explored this finding further using different schedule parameters, and confirmed that high scorers in UE did not differ in response rates between the two schedules.
