摘　　要：内隐重评是一种被广泛使用的情绪调节策略,它能够降低个体对负性情绪的紧张度和对情绪显著性敏感大脑区域的活性,但内隐重评相关神经调节的时间进程仍不清晰。是否内隐重评指示语过早地引发了对情绪刺激的注意偏向和预期加工还不确定。研究采用事件相关电位的方法考察了内隐重评策略对负性情绪的调节作用、调节的时间进程以及指示语所引发的生理变化。结果显示相对于被动观看负性图片,内隐重评成功地降低了晚正电位的波幅与自我报告的情绪紧张度;内隐重评显著降低负性情绪开始于刺激呈现后500ms,并持续整个图片呈现的过程;内隐重评指示语引发了个体对即将到来的负性刺激的注意朝向和预期加工。Emotion regulation can be achieved through a number of processes.Implicit/automatic emotional regulation is a widely used form of emotion regulation.Studies have shown that implicit emotion regulation strategies such as reappraisal can reduce the intensity of negative experience and brain activity sensitive to emotional salience.However,the time course of implicit reappraisal-related neural modulation remains unclear.It is unknown whether implicit reappraisal conditions before picture onset elicit attentional orienting towards and anticipation of impending stimuli.To fill this gap in the field,we examined the electrocortical response to unpleasant pictures during the implicit reappraisal condition,the modulation’s time processing,and the physiological changes elicited by instruction cues.In this study,a total of 20 participants were recruited.The implicit reappraisal strategy by giving them precedent descriptions was used to attenuate the emotional impact of unpleasant pictures.Event-related brain potentials(ERPs) were recorded while participants passively viewed neutral,unpleasant,and reappraised the unpleasant pictures.Late positive potential(LPP) is a positive-going ERP that begins parietally 200 ms following stimulus onset.The LPP is related to attentional processing to stimuli with motivational significance,which is larger following the presentation of emotional compared with neutral visual stimuli.Stimuli-preceding negativity(SPN) is a negative slow-wave that grows with anticipation of an impending feedback stimulus.The SPN is believed to reflect attentional orienting towards and anticipation of impending stimuli.We focused on these two ERP components to examine the differences between passively viewed neutral pictures,passively viewed unpleasant pictures,and implicitly reappraised before the view of the unpleasant pictures.The main goal of the present study was to investigate whether an “implicit reappraisal strategy”would modulate the LPP and SPN associated with unpleasant picture viewing.The result
