The effects of sleep inertia immediately after the nighttime nap on error monitoring functions.

我们利用两个事件相关电位，即错误负性/错误相关负性（Ne/ERN）和错误正性（Pe），探讨了1小时小睡对长时间清醒期间错误监测功能的影响。参与者在小睡或清醒休息前（21:00）和后（02:00,03:00）分别执行刺激-反应相容性任务（箭头定向任务）。在03:00开始的测试期间，小睡的参与者比休息的参与者表现出更多的正确答案。而在Ne/ERN和Pe方面，两组间差异无统计学意义。

We explored the effects of a 1-h nap on error-monitoring function during a period of extended wakefulness, using two event-related potentials, i.e., error negativity/error-related negativity (Ne/ERN) and error positivity (Pe). Participants performed a stimulus-response compatibility task (the arrow-orientation task) before (21:00) and after (02:00, 03:00) the nap or awake-rest period. The participants who took a nap showed more correct responses than those who had a rest during the test period started at 03:00. However, concerning to Ne/ERN and Pe, there were no significant differences between the two groups.
