Goal-adaptive behavior requires the rapid detection of conflicts between actions and intentions or goals. Although many studies have focused in the past on the influence of negative affect on this cognitive control process (and more specifically, on error monitoring), little is known about the possible modulatory effects of positive affect on it. To address this question, we used a standard (positive) mood induction procedure (based on guided imagery) and asked participants to carry out a speeded go/no-go task while high-density electroencephalography was recorded concurrently. As a control condition, we used a group with neutral mood. Event-related potential results showed that the error-related negativity (ERN) component, reflecting early error detection within the dorsal anterior cingulate cortex, was not influenced by happy mood. In contrast, the subsequent error positivity (Pe) component, related to the appraisal of the motivational significance of errors, was reliably smaller in the happy than in the neutral mood group. Complementing source localization analyses showed that this effect was explained by decreased activation within the posterior cingulate and insular cortices. These results were obtained in the absence of group differences regarding behavioral performance and tonic arousal. These findings suggest that happy mood likely decreases and changes the motivational significance of worse-than-expected events (Pe), while leaving their earlier automatic detection (ERN) unaltered. We discuss these new results in terms of dynamic changes in the complex interplay of performance monitoring with motivation.
目标适应性行为需要快速检测行动与意图或目标之间的冲突。尽管过去许多研究聚焦于消极情绪对这种认知控制过程的影响（更具体地说，是对错误监测的影响），但对于积极情绪可能产生的调节作用却知之甚少。为了解决这个问题，我们采用了一种标准的（积极）情绪诱导程序（基于引导式意象），并要求参与者在同时记录高密度脑电图的情况下执行快速的“是/否”任务。作为对照条件，我们使用了一组处于中性情绪的参与者。事件相关电位结果显示，反映背侧前扣带回皮质早期错误检测的错误相关负波（ERN）成分不受愉快情绪的影响。相比之下，与错误的动机意义评估相关的后续错误正波（Pe）成分，在愉快情绪组中比在中性情绪组中确实更小。补充性的源定位分析表明，这种效应是由后扣带回和岛叶皮质内激活减少所解释的。这些结果是在行为表现和静息觉醒方面不存在组间差异的情况下获得的。这些发现表明，愉快情绪可能会降低并改变比预期更糟事件的动机意义（Pe），同时使其早期的自动检测（ERN）保持不变。我们从绩效监测与动机复杂相互作用的动态变化角度讨论了这些新结果。
