High schizotypal individuals manifest differential performance on time-based schedules of reinforcement

Experiments explored the performance of individuals with high schizotypal unusual experiences on time-based schedules of reinforcement: fixed interval (FI), and a differential reinforcement of low rate (DRL), schedule of reinforcements. Index of curvature analysis for the FI schedule, and inter-response time analysis for the DRL schedule, demonstrated that high scorers in unusual experiences responded after a longer period of time than low scorers. However, this was dependent on the presentation order of the schedules. Taken together, the results are consistent with disruptions in the timing performance of individuals with high psychometrically-defined unusual experiences.
