A young but chronic group of schizophrenic and affective disorders patients was tested for simple reaction time (RT) and RT while engaged in a concurrent task. The affective disorders patients were subdivided by the presence of psychotic features. The results show that extreme slowing of RT is due to psychoticism and is not characteristic of nonpsychotic affective illness. Extreme intrasubject variability, however, was specific to schizophrenia, and may be a trait marker of the disorder.
对一组患有精神分裂症和情感障碍的年轻慢性病患者进行了简单反应时间（RT）测试以及在同时执行一项任务时的反应时间测试。情感障碍患者根据是否存在精神病性特征进行了细分。结果表明，反应时间的极度减慢是由精神病性所致，并非非精神病性情感疾病的特征。然而，个体内部的极度变异性是精神分裂症所特有的，可能是该疾病的一种特质标记。
