Performance monitoring can be based on internal or external signals. We recorded event-related potentials (ERPs) to investigate whether relating performance to external signals affects internal performance monitoring. Thirty participants performed a task in which responses were followed by faces whose expressions were partially contingent upon performance. Instructions given to half of the participants mentioned a link between task performance and the upcoming face expression. Instructed participants showed smaller error-related negativity (Ne/ERN) to erroneous responses and larger N170 to faces as compared to participants in the not-instructed group. In addition, we observed a correlation between ΔNe/ERN and P1-latency benefit for angry faces after errors. Taken together, processing of internally generated signals for performance monitoring is reduced by instructions referring to an emotional face. Furthermore, we relate the correlation between the magnitude of internal monitoring and facilitation in processing angry faces to priming induced by the negative affective meaning of errors.
绩效监测可以基于内部或外部信号。我们记录了事件相关电位（ERP），以研究将绩效与外部信号相关联是否会影响内部绩效监测。30名参与者执行了一项任务，在该任务中，响应之后会出现面部，其表情部分取决于绩效。给予一半参与者的指示提到了任务绩效与即将出现的面部表情之间的联系。与未接受指示的组相比，接受指示的参与者对错误响应表现出较小的错误相关负波（Ne/ERN），对面部表现出较大的N170。此外，我们观察到错误后愤怒面孔的ΔNe/ERN与P1潜伏期益处之间存在相关性。综上所述，提及情绪化面孔的指示会减少用于绩效监测的内部生成信号的处理。此外，我们将内部监测的大小与处理愤怒面孔时的促进作用之间的相关性与错误的负面情感意义所引发的启动联系起来。
