Emotional-intensity is a core characteristic of affective events that strongly determines how individuals choose to regulate their emotions. Our conceptual framework suggests that in high emotional-intensity situations, individuals prefer to disengage attention using distraction, which can more effectively block highly potent emotional information, as compared with engagement reappraisal, which is preferred in low emotional-intensity. However, existing supporting evidence remains indirect because prior intensity categorization of emotional stimuli was based on subjective measures that are potentially biased and only represent the endpoint of emotional-intensity processing. Accordingly, this study provides the first direct evidence for the role of online emotional-intensity processing in predicting behavioral regulatory-choices. Utilizing the high temporal resolution of event-related potentials, we evaluated online neural processing of stimuli's emotional-intensity (late positive potential, LPP) prior to regulatory-choices between distraction and reappraisal. Results showed that enhanced neural processing of intensity (enhanced LPP amplitudes) uniquely predicted (above subjective measures of intensity) increased tendency to subsequently choose distraction over reappraisal. Additionally, regulatory-choices led to adaptive consequences, demonstrated in finding that actual implementation of distraction relative to reappraisal-choice resulted in stronger attenuation of LPPs and self-reported arousal.
情绪强度是情感事件的一个核心特征,它强烈地决定了个体如何选择调节自己的情绪。我们的概念框架表明,在高情绪强度的情况下,个体更喜欢通过分散注意力来脱离注意力,与在低情绪强度下更受青睐的参与性重新评价相比,分散注意力可以更有效地阻止高度强烈的情绪信息。然而,现有的支持证据仍然是间接的,因为之前对情绪刺激的强度分类是基于主观测量,这些测量可能存在偏差,并且只代表了情绪强度处理的终点。因此,本研究为在线情绪强度处理在预测行为调节选择中的作用提供了首个直接证据。利用事件相关电位的高时间分辨率,我们在分散注意力和重新评价之间的调节选择之前,评估了刺激情绪强度的在线神经处理(晚期正电位,LPP)。结果表明,强度的增强神经处理(增强的LPP振幅)独特地预测了(高于强度的主观测量)随后选择分散注意力而非重新评价的倾向增加。此外,调节选择导致了适应性后果,这体现在发现相对于重新评价选择,实际实施分散注意力会导致LPP和自我报告的唤醒更强烈的衰减。
