错误后减慢（PES）反映了有效的结果监控，表现为错误后反应时间变慢。认知控制假设 PES 取决于错误信息，而定向账户则假设 PES 取决于错误频率。这就提出了一个问题：结果效价和结果频率如何分别影响 PES 的产生。为了解决这个问题，我们改变了“伙伴”通过观察执行任务所犯的观察错误的概率（50/50和20/80，正确/错误），并研究了相应的行为和神经效应。在每次试验中，参与者首先查看据称由“伙伴”执行的侧翼跑的结果，然后自己执行侧翼跑。我们观察了两种错误率条件下的 PES。然而，脑电图数据表明，错误相关电位（oERN 和 oPe）和与注意力过程相关的节律振荡（α 带）分别对结果效价和结果频率敏感。重要的是，oERN 幅度与 PES 呈正相关。总而言之，这些发现支持认知控制帐户的假设，表明结果效价和结果频率都与 PES 相关。此外，PES的生成由oERN索引，而PES大小的调制可以反映在α带上。
Post-error slowing (PES) reflects efficient outcome monitoring, manifested as slower reaction time after errors. Cognitive control account assumes that PES depends on error information, whereas orienting account posits that it depends on error frequency. This raises the question how the outcome valence and outcome frequency separably influence the generation of PES. To address this issue, we varied the probability of observation errors (50/50 and 20/80, correct/error) the “partner” committed by employing an observation-execution task and investigated the corresponding behavioral and neural effects. On each trial, participants first viewed the outcome of a flanker-run that was supposedly performed by a ‘partner’, and then performed a flanker-run themselves afterwards. We observed PES in the two error rate conditions. However, electroencephalographic data suggested error-related potentials (oERN and oPe) and rhythmic oscillation associated with attentional process (alpha band) were respectively sensitive to outcome valence and outcome frequency. Importantly, oERN amplitude was positively correlated with PES. Taken together, these findings support the assumption of the cognitive control account, suggesting that outcome valence and outcome frequency are both involved in PES. Moreover, the generation of PES is indexed by oERN, whereas the modulation of PES size could be reflected on the alpha band.
