虽然精神分裂症患者，作为一个群体，表现出赤字的措施外显学习，目前还不清楚他们是否也有赤字的措施内隐学习。本研究采用系列反应时测验（SRT）对48例慢性精神分裂症住院患者和23例正常对照者的程序性学习进行了评估。此外，我们还研究了程序学习的临床相关性。SRT产生总的运动学习和两个子组件的指标：反应时学习，和序列学习。尽管患者在整体运动学习方面与正常对照组相比，但他们的序列学习显著低于正常对照组（P
Although schizophrenic patients, as a group, show deficits on measures of explicit learning, it is unclear whether they also have deficits on measures of implicit learning. The current study assessed procedural learning in a sample of 48 chronic schizophrenic inpatients and 23 normal controls using the serial reaction time test (SRT). In addition, we examined the clinical correlates of procedural learning. The SRT yields indices of total motor learning and two subcomponents: reaction time learning, and sequence learning. Although patients performed comparably to normal controls on total motor learning, they showed significantly less sequence learning (P
