本研究旨在探讨心动周期是否影响动作反馈的评价性加工。为此，我们研究了心动周期对事件相关脑电位（ERP）效应的影响，该效应指示了动作反馈的评价性处理[即，ERP效应，被解释为“坏”动作反馈引起的反馈相关负性（FRN）或“好”动作反馈引起的奖励正性（RewP）]。参与者进行了一项赌博任务，他们选择了两个刺激之一，并收到了一个行动反馈，表明金钱的收益或损失。每项试验都被回顾性地分为收缩期和收缩期试验;收缩期试验被定义为在收缩期呈现货币结局的试验，收缩期试验被定义为在收缩期呈现货币结局的试验。结果表明，FRN/RewP在收缩期试验中比在收缩期试验中大，这是由于增益而不是损失ERPs的调制。这些结果提供了证据，心脏传入信号的自然波动可以调节反馈的评价性处理。
The present study aimed to investigate whether the evaluative processing of action feedback is influenced by the cardiac cycle. To this aim, we examined the influence of the cardiac cycle on an event-related brain potential (ERP) effect that indexed the evaluative processing of action feedback [i.e., an ERP effect that interpreted as a feedback-related negativity (FRN) elicited by "bad" action feedback or a reward positivity (RewP) elicited by "good" action feedback]. Participants performed a gambling task in which they chose one of two stimuli and received an action feedback that indicated monetary gain or loss. Each trial was retrospectively classified into systole and diastole trials; systole trials were defined as those where monetary outcomes were presented during systole, and the diastole trials as those where monetary outcomes were presented during diastole. The results showed that the FRN/RewP was larger for the systole trials than for the diastole trials, which was due to the modulation of gain rather than loss ERPs. These results provide evidence that the natural fluctuation of cardiac afferent signals can modulate the evaluative processing of feedback.
