Abstract

Emotional reactivity and the time taken to recover, particularly from negative, stressful, events, are inextricably linked, and both are crucial for maintaining well-being. It is unclear, however, to what extent emotional reactivity during stimulus onset predicts the time course of recovery after stimulus offset. To address this question, 25 participants viewed arousing (negative and positive) and neutral pictures from the International Affective Picture System (IAPS) followed by task-relevant face targets, which were to be gender categorized. Faces were presented early (400-1500 ms) or late (2400-3500 ms) after picture offset to capture the time course of recovery from emotional stimuli. Measures of reaction time (RT), as well as face-locked N170 and P3 components were taken as indicators of the impact of lingering emotion on attentional facilitation or interference. Electrophysiological effects revealed negative and positive images to facilitate face-target processing on the P3 component, regardless of temporal interval. At the individual level, increased reactivity to: (1) negative pictures, quantified as the IAPS picture-locked Late Positive Potential (LPP), predicted larger attentional interference on the face-locked P3 component to faces presented in the late time window after picture offset. (2) Positive pictures, denoted by the LPP, predicted larger facilitation on the face-locked P3 component to faces presented in the earlier time window after picture offset. These results suggest that subsequent processing is still impacted up to 3500 ms after the offset of negative pictures and 1500 ms after the offset of positive pictures for individuals reacting more strongly to these pictures, respectively. Such findings emphasize the importance of individual differences in reactivity when predicting the temporality of emotional recovery. The current experimental model provides a novel basis for future research aiming to identify profiles of adaptive and maladaptive recovery.

摘要

情绪反应和从负面、压力等事件中恢复的时间是紧密相关的,两者对维持幸福感都至关重要。然而,情绪反应在刺激开始时预测刺激结束后恢复时间进程的程度尚不清楚。为了解决这个问题,25 名参与者观看了国际情感图片系统(IAPS)中的令人兴奋的(负面和正面)和中性图片,然后是与任务相关的人脸目标,这些目标需要进行性别分类。人脸在图片结束后 400-1500ms 或 2400-3500ms 呈现,以捕捉从情绪刺激中恢复的时间进程。反应时间(RT)的测量,以及与脸相关的 N170 和 P3 成分,作为情绪对注意力促进或干扰影响的指标。电生理效应表明,无论时间间隔如何,负性和正性图片都会促进面孔目标处理的 P3 成分。在个体水平上,对:(1)负性图片的反应性增加,以 IAPS 图片锁定的晚期正性电位(LPP)来量化,预测在图片结束后较晚的时间窗口呈现的面孔时,对面孔锁定的 P3 成分的注意力干扰更大。(2)正性图片,由 LPP 表示,预测在图片结束后较早的时间窗口呈现的面孔时,对面孔锁定的 P3 成分的促进作用更大。这些结果表明,对于对这些图片反应更强烈的个体,在负性图片结束后 3500ms 后和正性图片结束后 1500ms 后,后续处理仍然受到影响。这些发现强调了在预测情绪恢复的时间进程时,个体反应性差异的重要性。当前的实验模型为未来旨在确定适应性和适应性不良恢复特征的研究提供了新的基础。
