Self-reported Intolerance of Uncertainty (IU) is the tendency to find uncertainty aversive. There is a lack of empirical research on how IU modulates anticipatory responding during threatening contexts with different parameters of uncertainty.
Exploratory secondary analyses were conducted on an existing data set (n = 45) to examine whether IU is related to a particular parameter of uncertainty during instructed threat of shock (i.e. certain shock, certain safety from shock, outcome uncertainty of shock, temporal uncertainty of shock).
Analyses revealed that IU was associated with larger auditory startle blink during the anticipatory period for the certain safety from shock condition relative to the certain shock condition.
The sample was relatively small.
Individuals with higher self-reported IU may be more inclined to generalize threat to safety cues in the context of instructed threat of shock.
自我报告的不确定性容忍度（IU）是指对不确定性感到厌恶的倾向。在不同不确定性参数的威胁情境下，IU 如何调节预期反应，这方面的实证研究还很缺乏。
对现有数据集（n=45）进行了探索性二次分析，以检验 IU 是否与指令性电击威胁期间的一个特定不确定性参数有关（即确定的电击、确定的电击安全、电击结果的不确定性、电击时间的不确定性）。
分析显示，在确定的电击安全条件下，IU 与更大的听觉惊跳眨眼反应相关，而在确定的电击条件下，IU 与更大的听觉惊跳眨眼反应相关。
样本相对较小。
自我报告 IU 较高的个体可能更倾向于将威胁泛化到指令性电击威胁情境中的安全线索。
