认知重评对负性效价的抑制促进条件性恐惧消退

【摘要】：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。
[Abstract]:Cognitive reassessment can effectively reduce the negative emotional experience of individual emotional stimulation, but the effect of guided cognitive reassessment in the treatment of fear memory is controversial. This paper combines the cognitive reappraisal paradigm with the discriminative conditional fear response paradigm, and discusses the effect of guided cognitive reassessment training on the acquisition and regression of fear emotions, taking the titer and US expected values as indicators. The individuals with low cognitive reassessment ability were trained in instructive cognitive reassessment 24 hours before the experiment. The conditioned fear task lasted for 2 days, the first day completed the acquisition and extinction task of conditional fear, and the second day completed the task of reversion of conditional fear. The results showed that the efficacy of fear emotion in conditioned fear task was significantly lower after reevaluation training, which indicated that cognitive reassessment could effectively reduce the negative emotional experience of individuals with low cognitive reassessment ability under acute stress. All subjects successfully completed the task of acquisition and extinction of discriminative conditional fear, so the re-evaluation training did not weaken the ability of individuals to distinguish danger or security information. However, in the process of conditional fear regression, cognitive reassessment training accelerated fear regression, and the degree of conditional fear measured 24 hours later was significantly lower, indicating that guidance reassessment improved the regression efficiency of conditional fear memory. And weakened the regression of conditional fear back.
