【摘要】 言语幽默能够调节负性情绪,其认知因素体现为对言语信息的理解加工,情感因素则表现为情绪反应的引发。现有研究探讨了言语幽默在情绪调节中的作用,但针对阈下抑郁个体用言语幽默调节情绪的认知神经加工机制证据仍较少。基于言语幽默加工的三阶段理论,即不一致探测、不一致解决和欢笑阶段,本研究旨在探究阈下抑郁组与对照组在言语幽默调节负性情绪过程中神经机制的差异。本研究采用2×2混合实验设计。先用负性启动词诱发负性情绪,随后通过幽默语句或中性语句两种条件进行情绪调节,并分别在情绪诱发后和情绪调节后采集39名被试(阈下抑郁组与对照组)的主观情绪评分。行为结果表明,两类调节刺激均能提升情绪评分,但幽默条件下的情绪评分显著高于中性条件,说明言语幽默调节负性情绪的有效性。事件相关电位(ERP)结果表明,幽默条件下N400与LPP成分的激活显著增强,表明言语幽默通过认知因素与情感因素协同作用对负性情绪进行调节。与对照组相比,阈下抑郁组在右中央区表现出减弱的N400激活,表明其不一致探测能力的下降。在对照组中,幽默条件和中性条件在右额区的LPP幅值无显著差异,这表明幽默条件诱发的LPP可能被负性启动词诱发的LPP抵消,为言语幽默的情绪调节作用提供神经证据。在幽默条件下两组在右前额区的LPP无显著差异,表明言语幽默在两组中均能有效调节负性情绪,然而阈下抑郁个体在幽默条件下的LPP显著高于中性刺激,而对照组未出现此差异,进一步验证言语幽默在对照组中表现出更优的情绪调节效果,这与阈下抑郁个体的负性情绪偏向有关。事件相关振荡(ERO)结果显示阈下抑郁组在theta频段和beta频段激活增强,进一步揭示了抑郁倾向对言语幽默调节作用的神经机制的影响。本研究聚焦于言语幽默在调节负性情绪过程中的认知神经加工机制,揭示了对照组与阈下抑郁组在该过程中神经活动的差异。研究从神经语言学视角出发,为阈下抑郁个体提供基于言语幽默的情绪干预策略,拓展了语言干预在情绪调节领域中的应用可能性。更多还原

【Abstract】 Verbal humor processing,which integrates both cognitive and affective aspects,has been shown to effectively regulate negative emotions.The cognitive aspect of verbal humor processing involves the comprehension of linguistic information,while the affective aspect relates to the elicitation of affective responses.While previous studies have examined the role of humor in emotion regulation,there is limited evidence regarding the cognitive-neural processing mechanisms of this regulation in individuals with subthreshold depression.In light of the three stages involved in verbal humor processing,namely incongruity detection,incongruity resolution,and mirth,this study aims to explore group differences in the neural mechanisms of the regulation of negative emotions by verbal humor between individuals with subthreshold depression and controls.The current study employed a 2×2 mixed design.Thirty-nine participants(the subthreshold depression group and the control group)provided two emotion ratings after exposure to negative priming words and regulating stimuli(the humorous condition and the neutral condition).Behavioral results demonstrated that the regulating stimuli enhanced emotional ratings,with the humorous condition eliciting significantly higher post-regulation ratings than the neutral condition,suggesting that verbal humor plays a significant role in regulating negative emotions.The ERP results revealed that activation of the N400 and LPP components was significantly enhanced during the humorous condition,reflecting the joint regulatory effect of cognitive and affective aspects in verbal humor processing on negative emotions.Compared to the control group,the subthreshold depression group exhibited overall less N400 activation in the right central region,indicating their reduced capacity for detecting incongruity.In the control group,no significant difference in LPP amplitude was observed in the right frontal region between humorous and neutral conditions,which suggests that LPP evoked by the humorous condition may have been attenuated or masked by LPP elicited by the negative priming words,providing neural evidence for the role of verbal humor in regulating negative emotions.The two groups showed no difference in LPP in the humorous condition in the right frontal region,suggesting that the role of verbal humor in regulating negative emotions functions similarly in both groups.Individuals with subthreshold depression exhibited stronger LPP in response to humorous stimuli compared to neutral stimuli,whereas no such differential response was observed in the control group.It further provides evidence that the regulation effect of verbal humor is more pronounced in the control group due to the negative emotional bias of subthreshold depression individuals.ERO results demonstrated the effect of depression inclination on the neural mechanisms of the regulation of negative emotions by verbal humor,showing that the subthreshold depression group exhibited greater activation in the theta and beta bands.The current study investigates the cognitive-neural processing mechanisms underlying the regulation of negative emotions by verbal humor,revealing different neural activity between controls and individuals with subthreshold depression.Adopting a neurolinguistic perspective,the study develops intervention strategies based on verbal humor for individuals with subthreshold depression,thereby expanding the potential applications of linguistic approaches in emotion regulation.更多还原
