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

我们使用两种事件相关电位，即，误差负性/误差相关负性（Ne/ERN）和误差正性（Pe）。参与者在午睡或清醒休息期之前（21：00）和之后（02：00，03：00）执行刺激-反应兼容性任务（箭头定向任务）。在测试期间，午睡的参与者比在03：00开始的测试期间休息的参与者表现出更多的正确反应。而Ne/ERN和Pe两组间无显著性差异。

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.
