Simple reaction time (SRT) was measured in schizophrenic, bipolar affective disorder, and never-psychotic outpatients to determine the specificity of SRT crossover to schizophrenia. A crossover pattern like that reported in other studies was found among the schizophrenics, but the average curve was not different from that of the other groups. Schizophrenics tended to have higher rates of crossover at the 7-second preparatory interval (47% vs. 17%–28%) but not substantially so. These data question the specificity of this behavioral trait to schizophrenics. |
