基于执行意图的认知重评对负性情绪的持续调节效应：纵向脑电证据
Sustainable regulation effects of implementation intention-based reappraisal on negative emotions: Longitudinal EEG evidence
基于执行意图的认知重评(Implementation Intention-based Reappraisal, IIR)作为一种执行意图(即if-then计划)与适应性认知重评相结合的新自动化情绪调节策略，可以在不增加认知负荷的情况下实现对负面情绪的调节，且该调节效应可以从设定情境(If情境)泛化到非设定情境。然而，以往研究未关注IIR的泛化效果是否具有可持续性。为解决这一问题，本研究采用脑电技术结合图片观看任务，以被试自我报告的效价、唤醒度和晚期正电位(late positive potential, LPP)为指标纵向考察IIR对被试当下及未来一周的情绪调节效果。结果显示，在第0 ~ 7天，相比控制组，IIR组对设定负性情境(血腥图片)的情绪体验及唤醒水平持续降低；且该调节效应同样稳定出现在对非设定情境(非血腥图片)的唤醒度评价上；同时，在第0天、第3天和第7天，IIR组相比控制组有更小的中央顶区LPP (400 ~ 1500 ms)波幅和额区LPP (400 ~ 1100 ms)波幅；且中央顶区LPP波幅与唤醒度存在显著正相关。上述结果说明IIR不仅能长期调节负性情绪并产生泛化效应，且其泛化效果存在一定的持续性。这一研究为IIR在情绪调节领域的有效性和稳定性提供了实证支持。

Implementation Intention-based Reappraisal (IIR) is a novel automatic emotion regulation strategy that combines implementation intentions (if-then plans) with adaptive cognitive reappraisal to regulate negative emotions without increasing cognitive load. Moreover, this regulation effect can generalize from specified situations (if situations) to unspecified situations. However, previous studies have not focused on whether the generalization effect of IIR is sustainable.To address this gap, this study utilized EEG technology in combination with a picture-viewing task to longitudinally investigate the emotion regulation effects of IIR in the present and over the following week, using participants self-reported valence, arousal, and late positive potential (LPP) as indicators. Specifically, 51 valid participants were randomly assigned to the IIR group (25 individuals) and the control group (26 individuals). The two groups performed a picture-viewing task and all participants valence and arousal for picture stimuli were simultaneously recorded at both the IIR acquisition phase (Day 0) and the post-IIR acquisition phase (Day 1, Day 3, Day 5, and Day 7), and their EEG activities for picture stimuli were recorded on Day 0, Day 3, Day 7. After data reduction and preprocessing, behavioral analysis included 49 participants (24 in the IIR group, 25 in the control group), and EEG analysis involved 44 participants (22 in each group).Subjective self-reported results revealed that, compared to the control group, the IIR group sustainably decreased valence and arousal ratings for bloody pictures (specified situations) from Day 0 to Day 7. Furthermore, the diminishing effect of IIR on arousal also consistently appeared in unspecified situations (non-bloody pictures), suggesting that the generalization effect of IIR was somewhat persistent. The event-related potential (ERP) results showed that, compared to the control group, the IIR group had smaller amplitudes of centro-parietal LPP (in the time window of 400 ~ 1500 ms) and frontal LPP (in the time window of 400 ~ 1100 ms) on Day 0, Day 3, and Day 7, suggesting that the sustainable effect of IIR was stable on LPP indicators. Additionally, there was a significant positive correlation between centro-parietal LPP (in the time window of 400 ~ 2500 ms) amplitude and arousal. Together, these findings suggest that IIR exhibits sustainable regulation and generalization effects on negative emotions.In conclusion, IIR could sustainably regulate negative emotions and produce generalization effects as evidenced by both behavioral and ERP indicators. This study provides additional evidence supporting the stability and effectiveness of IIR in emotion regulation. In addition, these findings contribute to advancing the theory of automatic emotion regulation. Specifically, the present study not only supports the auto-motive model of nonconscious goal pursuit and the temporal processing model of controlled-automatic emotion regulation, but also extends these theories by demonstrating the stability and generalization of IIRs effects on emotion regulation. Moreover, this study has certain clinical implications for interventions targeting emotional disorders. For example, IIR may be an effective approach for treating co-morbid symptoms of anxiety and depressive disorders.
