情绪调节中的认知重评创造力

情绪调节能力是维护个体心理健康和生活幸福的基本能力。认知重评创造力是个体面对负性情境时能够自发产生多种认知重评策略的能力, 是情绪调节任务中的创造性行为。研究表明, 认知重评创造力与发散性思维和开放性正相关, 与神经质、特质愤怒无关; 创造性的认知重评策略或运用隐喻和类比的高水平认知重构更有利于负性情绪的调节; 创造性的认知重评可以通过基于杏仁核的显著情绪唤醒, 基于海马的新联想形成和基于纹状体的精神奖赏的中介来调节情绪, 从而产生可以保存在长时记忆中的新颖的、积极的情绪体验。上述结果支持认知重评的创造性重构理论。认知重评创造过程需要自上而下的认知控制和情绪表征的特定执行功能。未来研究可以扩大被试群体, 完善认知重评创造力的测量方法, 探索影响认知重评创造力的情境因素和内在因素, 以及进一步揭示认知重评创造力区别于传统创造力的特别加工或反应机制的神经机制。     

认知重评的创造性对负性情绪调节的影响

以轻度负性图片为实验材料,采用自发性和指导性的认知重评策略,结合情绪的主观评定和生理指标,考察认知重评的创造性对负性情绪调节的影响,以及特质焦虑是否在其中起调节作用。结果发现：(1)自评和他评的认知重评创造性与情绪调节有效性呈显著正相关;(2)相比低创造性的认知重评,高创造性的认知重评对负性情绪的调节效果更好,并伴随着适应性的生理反应,皮电和心率显著下降;(3)相比低特质焦虑个体,高特质焦虑个体更容易体验到高负性情绪,但经过认知重评后两者的情绪调节效果无显著差异。结果表明,创造性认知重评促进负性情绪调节,特质焦虑在创造性认知重评与负性情绪调节之间不起调节作用。结果支持认知重评的创造性重构理论。     

认知重评策略对注意分配的影响

认知重评是采用对当前刺激情境的意义进行重新解释来改变情绪体验的情绪调节策略。该研究以31名大学生为被试,采用负性情绪图片作为刺激材料,2(是否认知重评:被动观看、认知重评)×2(情绪词:中性词、负性词)的两因素完全被试内设计,考察认知重评对情绪体验的调节作用是否通过影响对注意的分配来实现的。结果发现:(1)认知重评条件下负性情绪体验的强度比被动观看条件下显著降低。(2)对于中性词,认知重评阶段的反应时显著快于被动观看阶段,t(29)=-5.09,p0.01。而对于负性词,认知重评阶段的反应时显著长于被动观看阶段,t(29)=2.43,p0.05。以上结果说明,认知重评的情绪调节策略可以通过减弱对负性刺激的注意偏向来降低负性情绪体验。     

积极与分离认知重评负性情绪调节效果和成功程度的差异：青年、中老年和少年的实验结果

考察了少年、青年和中老年两种认知重评在负性情绪调节效果和成功程度上的差异。差异分析表明：少年分离认知重评的成功程度显著高于积极认知重评;青年积极认知重评的情绪调节效果显著好于分离认知重评;中老年积极认知重评的情绪调节效果和成功程度均显著好于分离认知重评。三组被试两种认知重评的情绪调节效果之间均无显著差异。青年分离认知重评的成功程度分别显著高于少年和中老年;青年和中老年积极认知重评的成功程度均显著高于少年。     

抑郁症患者认知重评和分心情绪调节的有效性:ERPs研究

使用事件相关电位(ERPs)技术考察抑郁症患者在指导下使用认知重评和分心策略调节负性情绪的有效性。结果发现抑郁症患者可以使用认知重评策略降低负性情绪体验,同时也表现出LPP波幅显著降低,但LPP波幅依然比正常被试大;抑郁症患者使用分心策略后没有降低负性情绪体验,但LPP波幅比正常个体小。结果表明,轻中度抑郁症被试在指导条件下,可以使用认知重评策略并表现出一定程度的有效性,但其认知重评的效果低于正常被试;抑郁症被试使用分心策略的效果好于正常被试。     

创造性认知重评在情绪调节中的迁移效应及其神经基础

认知重评在负性情绪调节中发挥着重要的作用。针对传统认知重评重构程度不够高、调节效果不明显的问题, 研究团队在先前的工作中提出了一种使消极情绪“转负为正”的高效情绪调节方法, 即创造性认知重评, 这种调节策略伴随着大脑海马的新颖联结形成和杏仁核的积极情绪唤醒。然而这些工作采用“指导式”的重评更像是对重评解读的“理解”而非主动的情绪调节; 鉴于主动情绪调节的产生难度较大, 造成创造性认知重评在实际应用上的两难困境。基于此, 本项目拟指导受试者进行创造性认知重评的学习, 通过学习将这种策略迁移并且应用到生活中的负性情绪调节事件中。具体研究内容包括：(1)行为学上, 探索创造性认知重评在大学生群体和青少年群体负性情绪调节中的迁移效应; (2)影像学上, 探索创造性认知重评迁移前后在脑认知表征模式上的变化。本项目是对已有工作基础的延伸和拓展, 为验证和推动创造性认知重评成为一种可学、可用、高效的情绪调节策略奠定理论基础。     

8~12岁儿童抑郁与认知重评的关系：悲伤面孔注意偏向的中介作用

探讨8~12岁学龄儿童抑郁与认知重评情绪调节策略的关系及其作用机制。研究1采用问卷法和行为实验法分别考察儿童抑郁对认知重评策略使用倾向和使用能力的作用; 研究2结合眼动技术考察对情绪信息注意偏向在儿童抑郁和认知重评关系间的中介作用。结果发现：(1) 抑郁与儿童认知重评使用倾向间存在显著负相关; (2) 抑郁对儿童负性情绪向下调节的重评效果有显著影响; (3) 悲伤面孔注意解除困难在抑郁与认知重评使用倾向之间起中介作用。     

情绪调节对工作记忆的影响

本研究采用实验室研究方法,以情绪调节策略中的认知重评和表达抑制为自变量,以工作记忆绩效和情绪自评差异为因变量,旨在探讨不同的情绪调节策略对工作记忆的影响。结果表明:负性情绪使工作记忆绩效降低;通过情绪调节,可以改变负性情绪对工作记忆的影响效果;不同情绪调节策略对工作记忆影响效果不同:认知重评缓解负性情绪下工作记忆绩效的下降,表达抑制加剧负性情绪下工作记忆绩效的下降。     

负性情绪调节中认知重评和分心策略的作用:ERPs研究

采用事件相关电位技术,考察了认知重评和分心两种情绪调节策略对负性情绪体验和脑电活动的影响。结果发现,认知重评后被试的负性情绪体验强度和LPP波幅(300~1300ms)比简单注视条件下低;分心后被试的负性情绪体验强度比简单注视条件下低,但LPP波幅显示比简单注视条件下高。这说明认知重评和分心对负性情绪体验和脑电活动的影响不同,负性刺激再次呈现时认知重评优于分心策略的调节。该研究为认知重评和分心的比较研究提供了神经电生理学方面的证据。     

认知重评对负性效价的抑制促进条件性恐惧消退

认知重评能有效降低个体对情感刺激的负性情绪体验, 但指导性认知重评在恐惧记忆治疗中效果存在争议。本文将认知重评范式与辨别式条件恐惧反应范式结合, 以效价和US预期值为指标, 探讨指导性认知重评训练对恐惧情绪习得和消退的影响效果。以低认知重评能力个体为被试, 在实验前24 h进行指导性认知重评训练。条件性恐惧任务为期2天, 第一天完成条件性恐惧的习得和消退任务, 第二天完成条件性恐惧的再消退任务。结果显示, 经过重评训练后个体在条件性恐惧任务中的恐惧情绪效价显著较低, 说明认知重评有效降低低认知重评能力个体在急性应激状态下的负性情绪体验。所有被试均成功完成辨别式条件性恐惧的习得和消退任务, 因此重评训练并不削弱个体对危险或者安全信息的辨别能力。但在条件性恐惧的消退过程中, 认知重评指导训练加快了恐惧消退, 且24 h后测得的条件性恐惧程度显著较低, 说明指导性重评提高了条件性恐惧记忆的消退效率, 并减弱了条件性恐惧的消退返回。     

Increasing negative emotions by reappraisal enhances subsequent cognitive control: A combined behavioral and electrophysiological study

To what degree do cognitively based strategies of emotion regulation impact subsequent cognitive control? Here, we investigated this question by interleaving a cognitive task with emotion regulation trials, where regulation occurred through cognitive reappraisal. In addition to obtaining self-reports of emotion regulation, we used the late positive potential (LPP) of the event-related brain potential as an objective index of emotion regulation. On each trial, participants maintained, decreased, or increased their emotional response to an unpleasant picture and then responded to a Stroop stimulus. Results revealed that (1) the magnitude of the LPP was decreased with reappraisal instructions to decrease negative emotion and were enhanced with reappraisal instructions to increase negative emotion; (2) after cognitive reappraisal was used to increase the intensity of negative emotion, RT interference in the subsequent Stroop trial was significantly reduced; and (3) increasing negative emotions by reappraisal also modulated the cognitive control-related sustained potential. These results suggest that increasing negative emotions by cognitive reappraisal heightens cognitive control, which may be sustained for a short time after the regulation event.     

不同民族文化对负性情绪调节的影响:来自ERPs的证据

采用认知重评和表达抑制策略考察不同民族文化对负性情绪调节主观体验和事件相关电位活动的影响。结果发现,汉族和少数民族文化个体在两种策略下均呈现负性情绪感受显著降低,并且汉族表达抑制的情绪体验得分低于少数民族。此外,负性情绪图片相比中性图片诱发了更大的P2成分,表达抑制相比认知重评在额-中区诱发了更大的P3成分。更重要的是,900~1200ms时间窗内,汉族个体认知重评和表达抑制后LPP波幅均降低,但少数民族文化个体仅在认知重评条件表现出LPP波幅的显著下降。以上结果表明不同民族文化背景下负性情绪调节的效果不同。     

Differences in emotion modulation using cognitive reappraisal in individuals with and without suicidal ideation: An ERP study

Difficulties in emotion regulation have been associated with increased suicidal thoughts and behaviours. The majority of studies have examined self-reported use of emotion regulation strategies. In contrast, the current study focused on a direct measure of individuals’ ability to use a specific emotion regulation strategy, cognitive reappraisal, using the late positive potential (LPP), an event-related potential component that reflects attention to emotional stimuli. Specifically, the cognitive reappraisal ability of 33 undergraduate students was assessed via an image-viewing task during which the participants had to passively view, increase or reduce their emotions in response to looking at neutral, positive or dysphoric images. We found that participants with a history of suicidal ideation (SI) had significantly higher LPP when asked to reduce negative emotion in response to dysphoric images, compared to individuals with no history of SI. These findings suggest that difficulties with using cognitive reappraisal, specifically to decrease negative affect, might be linked to suicide risk.     

表达抑制调节负性情绪的男性优势——来自事件相关电位的证据

生活经验和文献证明,男性相比女性有更少的情绪表达行为。据此,本研究假设表达抑制进行负性情绪调节具有男性优势,而采用认知重评调节时可能没有该性别差异。在不同的实验阶段,被试分别采用自由观看、表达抑制和认知重评策略观看负性情绪图片,同时记录事件相关电位(ERP),以及使用各种策略之后的主观情绪体验。结果表明,采用表达抑制和认知重评调节情绪后,被试报告的负性情绪体验没有出现男女差异。然而,对ERP晚期正电位(Late Positive Potential,LPP)的统计分析发现,LPP的中期(2000~3000 ms)与晚期(3000~4000 ms)波幅均出现了调控策略与性别的交互作用。对男性而言,负性图片诱发的LPP波幅(2000~4000 ms)在表达抑制条件下相比自由观看条件出现显著降低,但女性没有出现上述效应。此外,在LPP各个时间窗口,采用认知重评策略进行情绪调节时均无显著性别差异。上述结果表明采用表达抑制策略进行负面情绪调节时,男性具有相比女性更好的调控效果。这提示男性比女性更适合采用抑制情绪表达的方式进行日常情绪管理。这种性别优势可能来源于社会对男女性性别角色的不同期望。     

Effects of incidental positive emotion and cognitive reappraisal on affective responses to negative stimuli

Previous studies have identified two powerful ways to regulate emotional responses to a stressor: experiencing incidental positive emotions and using cognitive reappraisal to reframe the stressor. Several cognitive and motivational theories of positive emotion support the formulation that incidental positive emotions may facilitate cognitive reappraisal. To test the separate and interacting effects of positive emotions and cognitive reappraisal, we first adapted an established picture-based reappraisal paradigm by interspersing blocks of positive emotion inducing and neutral pictures. Across two pre-registered studies (Studies 1, 2), reappraisal effectively decreased self-reported negative emotions and increased self-reported positive emotions; however, experiencing incidental positive emotions did not facilitate reappraisal success. In another preregistered study (Study 3), we employed a more powerful positive emotion induction via virtual reality (VR), used a social stress anticipation task, and instructed participants to reappraise the anticipated stressor positively. Although there was a robust effect of the positive emotion induction (relative to the neutral induction) on feeling more positive emotions throughout stress anticipation, the results again indicated that incidental positive emotions did not facilitate cognitive reappraisal. We propose that incidental positive emotions and cognitive reappraisal may constitute separate pathways of influence when regulating one's responses to negative events.     

Event-related induced frontal alpha as a marker of lateral prefrontal cortex activation during cognitive reappraisal

Electrocortical activity, typically used to track the effects of cognitive reappraisal on the processing of emotional stimuli, has not been used to index the prefrontal-cortex-mediated regulatory mechanisms responsible for these effects. In the present study, we examined the novel possibility that induced frontal alpha (i.e., 8?C13?Hz), shown to reflect the inhibition and disengagement of task-relevant cortical regions, may be quantified to explore cortical activation that is specifically enhanced during cognitive reappraisal. For this purpose, 44 participants viewed unpleasant and neutral pictures followed by auditory instructions to either continue viewing the picture or reduce their emotional response to the picture by making the picture seem less emotional (i.e., cognitive reappraisal). In line with previous work, unpleasant pictures elicited a larger late positive potential (LPP) than did neutral pictures. Also corroborating previous work, the mid-latency LPP was reduced when pictures were cognitively reappraised. However, the present study showed for the first time that whereas unpleasant pictures elicited higher frontal alpha power bilaterally than did the neutral pictures, frontal alpha power was reduced (indicative of more activation and cognitive control) during cognitive reappraisal of both picture types over the left hemisphere. Taken together, the LPP and event-related induced frontal-alpha findings contribute unique information about the distinct neural substrates and cognitive processes underlying reappraisal.     

积极情绪调节的ERP研究

利用ERP技术研究认知重评对积极情绪调节及后续认知任务的影响。先呈现积极图片,要求被试被动观看或认知重评。接着呈现情绪词,要求被试进行效价判断。结果显示,在情绪调节阶段,与被动观看或评价忽视相比,评价重视调节下的LPP更大。在词呈现阶段,被试的反应时受情绪调节的影响,表现为:评价忽视>评价重视>被动观看。在160-720ms期间,认知重评之后词汇所诱发的ERP与被动观看后词汇的ERP有显著差异,支持情绪调节损耗认知资源的观点。     

Reappraisal modulates the electrocortical response to unpleasant pictures

Cognitive strategies such as reappraisal reduce the intensity of negative experience and brain activity that is sensitive to emotional salience. The time course of reappraisal-related neural modulation remains unclear, and it is unknown whether the electrocortical response to emotional stimuli is sensitive to reappraisal. Event-related brain potentials were recorded first while participants passively viewed pleasant, unpleasant, and neutral pictures, and then during an emotion regulation block in which participants were instructed to attend to or reappraise unpleasant pictures. The late positive potential (LPP) was enhanced for pleasant and unpleasant pictures in the passive viewing block, and reappraisal resulted in a reliably reduced LPP—a protracted modulation that began 200 msec after stimulus onset. The degree of LPP modulation was positively related to reductions in the self-reported emotional intensity that followed emotion regulation instructions. These results indicate that reappraisal modulates early electrocortical activity that is related to emotional salience, and that the LPP is a useful tool for studying emotion regulation.     

The effect of cognitive reappraisal on long‐term emotional experience and emotional memory

One's ability to properly regulate emotion is critical to psychological and physical well‐being. Among various strategies to regulate emotion, cognitive reappraisal has been shown to modulate both emotional experience and emotional memory. However, most studies of reappraisal have focused on reappraisal of negative situations, with reappraisal of positive emotion receiving considerably less attention. In addition, the effects of reappraisal on emotional reactions to stimuli are typically only assessed either immediately or after a short delay, and it remains unclear whether reappraisal effects persist over longer time periods. We investigated the effect of cognitive reappraisal on emotional reactions and long‐term episodic memory for positive and negative stimuli. Men and women viewed emotionally negative, positive, and neutral pictures while they were instructed to either increase, decrease, or maintain the initial emotional reactions elicited by the pictures. Subjective ratings of emotional valence and arousal were assessed during the regulation task and again after 1 week. Memory for the pictures was assessed with free recall. Results indicated that pictures accompanied by instructions to increase emotion were better recalled than pictures reappraised to decrease emotion. Modulation of emotional arousal elicited by stimuli persisted over a week, but this effect was observed only for men. These findings suggest that cognitive reappraisal can have long‐lasting effects on emotional reactions to stimuli. However, the sex differences observed for the effects of reappraisal on emotional reactions highlight the importance of considering individual differences in the effects of regulation.
