ResumoThe present study investigated the relationship between reaction time crossover and schizotypy as measured by Chapman's Physical Anhedonia Scale (PAS). Twenty PAS-identi-fied schizotypal college students and 20 nonschizotypal students were administered a computerized version of Rodnick and Shakow's crossover reaction time task. The hypothesized interaction (crossover) between preparatory interval duration and preparatory interval presentation pattern was observed for PAS-identified schizotypics. Results indicated that subjects identified on the basis of the PAS evidenced reaction time crossover patterns similar to those observed in schizophrenic and at-risk populations.
