由于预测危险是调节焦虑的关键因素，缺乏恐惧条件反射会导致情境焦虑的不适应。在两个实验中，采用虚拟现实条件反射任务评估线索学习和情境焦虑与恐惧增强惊吓和主观恐惧。在实验1中，不适应提示导致持续的情境焦虑状态（主观恐惧和惊吓）。特质焦虑与学习线索偶发事件无关，但学习失败的参与者在自我报告的注意力控制测试中得分较低。部分学习了提示偶然性的人未能推断出情境的安全性，因此并没有减少他们的情境焦虑。实验2特别关注隔离这一过程，并证明特质焦虑与情境焦虑的适应性调节之间存在负相关。总之，预测威胁有助于但并不自动意味着对情境焦虑的成功调节。高特质焦虑可能增加情境焦虑调节不足的风险。(C) 2012 Elsevier B.V.版权所有
Deficient fear conditioning leads to maladaptive contextual anxiety as predicting danger is a key factor in regulating anxiety. A virtual reality conditioning task was used to evaluate cue learning and contextual anxiety with fear-potentiated startle and subjective fear in two experiments. In Experiment 1, failure to condition to a cue resulted in a constant state of context anxiety (subjective fearfulness and startle). Trait anxiety was unrelated to learning cue contingencies but the participants who failed to learn scored lower on a self-report measure of attentional control. Part of the group that learned the cue contingency failed to deduce safety of the context and hence did not reduce their contextual anxiety. Experiment 2 specifically focused on isolating this process and demonstrated an inverse association between trait anxiety and adaptive modulation of contextual anxiety. In conclusion, predicting threat aids in but not automatically implies successful regulation of contextual anxiety. High trait anxiety may increase risk of deficient modulation of contextual anxiety.
