【摘要】：恐惧的过度泛化是焦虑障碍的核心症状之一,表现为患者对与原危险刺激极不相似的安全刺激也产生恐惧反应。本研究采用经典条件恐惧范式,以US主观预期、回溯性恐惧评定、回溯性效价评定和皮电反应作为恐惧反应的指标,通过"最好自我"训练来诱发被试的积极情绪,考察了恐惧习得后的积极情绪对于恐惧泛化的影响。本研究发现,积极情绪能有效地抑制条件性恐惧的泛化,增强被试对安全信号的学习,并对消退后的恐惧重建现象起到预防作用。研究同时显示,恐惧泛化在主观评定指标和生理指标间出现了分离,这表明积极情绪对恐惧泛化的抑制作用是一个综合的过程,可能涉及到不同的作用机制。本研究结果提示可以通过诱发积极情绪,抑制条件性恐惧的泛化,对临床干预有一定的启发意义。
[Abstract]:The overgeneralization of fear is one of the core symptoms of anxiety disorder. This study adopts the classical conditional fear paradigm, using US subjective expectation, retrospective fear assessment, retrospective titer evaluation and electrodermic response as the indicators of fear response, and induces the positive emotion of the subjects through "best self" training. The effect of positive emotion after fear acquisition on the generalization of fear was investigated. This study found that positive emotion can effectively inhibit the generalization of conditional fear, enhance the participants' learning of safety signals, and prevent the phenomenon of fear reconstruction after extinction. At the same time, the study shows that fear generalization is separated between subjective evaluation index and physiological index, which indicates that the inhibitory effect of positive emotion on fear generalization is a comprehensive process, which may involve different mechanisms. The results suggest that the positive emotion can be induced and the generalization of conditional fear can be inhibited, which is instructive to clinical intervention.
