Abstract：
UNASSIGNED: The study aimed to examine the roles of anxiety and intolerance of uncertainty (IU) in conditioned fear learning under an uncertain context induced by the contingency reversal of the association between the conditioned stimulus and the unconditioned stimulus (CS-US).
UNASSIGNED: The study sample comprised 53 participants, randomly divided into two groups: a non-instruction group and an instruction group. The experimental procedure encompassed five stages: pre-acquisition, acquisition, generalization, reversal acquisition, and reversal generalization. Our study primarily focused on analyzing a moderated mediation model.
UNASSIGNED: In the instructed group, we observed that the reversed fear generalization response was directly influenced by the pre-reversal fear generalization response, while also being indirectly mediated by the IU factor. However, in the non-instructed group, we did not find a significant mediating effect of IU. Moreover, we noted that the mediation of IU was contingent on the instructional information. It is noteworthy that anxiety did not exhibit a discernible role in conditioned fear within the uncertainty condition in our study.
UNASSIGNED: The findings provide novel insights into fear-related phenomena, emphasizing the intricate interplay between individual traits and fear generalization under conditions of uncertainty. They contribute to understanding the mechanisms of emotional and cognitive interactions in uncertain conditions.

摘要：
■该研究旨在研究在条件刺激和非条件刺激（CS-US）之间的关联的偶然逆转引起的不确定背景下，条件恐惧学习中的焦虑和不确定性不容忍（IU）的作用。
■研究样本包括53名参与者，随机分为两组:非指令组和指令组。实验过程包括五个阶段：预采集，收购,泛化，反向收购，和逆转泛化。我们的研究主要集中在分析一个适度的调解模型。
■在指示的组中，我们观察到逆转恐惧泛化反应直接受到逆转前恐惧泛化反应的影响，同时也由IU因子间接介导。然而,在非指导组中，我们没有发现IU的显著中介效应.此外，我们注意到IU的调解取决于教学信息。值得注意的是，在我们研究的不确定性条件下，焦虑在条件性恐惧中没有表现出明显的作用。
■这些发现为恐惧相关现象提供了新的见解，强调在不确定性条件下个体特征和恐惧泛化之间复杂的相互作用。它们有助于理解不确定条件下的情感和认知互动机制。
