本研究旨在探讨动作反馈的评价性加工是否受到时间预测的调节。为此，我们研究了动作反馈时间的可预测性对ERP效应的影响，该ERP效应索引了动作反馈的评价性处理，即ERP效应被解释为由“坏”动作反馈引起的反馈相关负性（FRN）或由“好”动作反馈引起的奖励正性（RewP）。在两种类型的实验块中，参与者执行赌博任务，其中他们选择两张牌中的一张，并收到指示金钱收益或损失的行动反馈。在固定的块中，参与者的选择和动作反馈的开始之间的时间间隔在单独的块中固定在0，500或1,000 ms;因此，动作反馈的时间是可预测的。在混合区组中，时间间隔是以相等的概率从相同的三个间隔中随机选择的;因此，时间的可预测性较低。结果表明，对于0 ms间期试验，混合区组的FRN/RewP小于固定区组，而对于500 ms和1，000 ms间期试验，两种区组类型之间没有差异。有趣的是，较小的FRN/RewP是由于增益ERP的调制，而不是损失ERP。这些结果表明，时间预测可以调节行动反馈的评估处理，尤其是良好的反馈，例如表明金钱收益的反馈。
The present study aimed to investigate whether or not the evaluative processing of action feedback can be modulated by temporal prediction. For this purpose, we examined the effects of the predictability of the timing of action feedback on an ERP effect that indexed the evaluative processing of action feedback, that is, an ERP effect that has been interpreted as a feedback‐related negativity (FRN) elicited by “bad” action feedback or a reward positivity (RewP) elicited by “good” action feedback. In two types of experimental blocks, the participants performed a gambling task in which they chose one of two cards and received an action feedback that indicated monetary gain or loss. In fixed blocks, the time interval between the participant's choice and the onset of the action feedback was fixed at 0, 500, or 1,000 ms in separate blocks; thus, the timing of action feedback was predictable. In mixed blocks, the time interval was randomly chosen from the same three intervals with equal probability; thus, the timing was less predictable. The results showed that the FRN/RewP was smaller in mixed than fixed blocks for the 0‐ms interval trial, whereas there was no difference between the two block types for the 500‐ms and 1,000‐ms interval trials. Interestingly, the smaller FRN/RewP was due to the modulation of gain ERPs rather than loss ERPs. These results suggest that temporal prediction can modulate the evaluative processing of action feedback, and particularly good feedback, such as that which indicates monetary gain.
