Attentional control (AC) is an individual difference variable indexing the ability to voluntarily focus attention and shift attention when desired. AC is thought to impact the experience of fear by facilitating the disengagement of attention from threat and promoting the deployment of attentional resources toward regulatory or coping strategies. Whereas previous research has focused on visual threat cues, in the current study we examined whether this model also applies to interoceptive threat by evaluating the extent to which individual differences in AC moderated the relationship between trait anxiety and self-reported fear in response to a single vital capacity inhalation of a 35% CO(2), 65% balanced O(2) gas mixture. The sample comprised a large nonclinical group of young adults (N=128). Results indicated that AC moderated the relationship between trait anxiety and fearful responding to the challenge. Findings suggest that AC plays a significant and clinically important role in modulating self-reported fear.
注意控制（AC）是个体差异变量，用于衡量自愿集中注意力和在需要时转移注意力的能力。AC 被认为通过促进注意力从威胁中解脱出来并促进注意力资源的部署到调节或应对策略上来影响恐惧体验。虽然之前的研究集中在视觉威胁线索上，但在当前的研究中，我们通过评估 AC 的个体差异在多大程度上调节了特质焦虑与对单次肺活量吸入 35%CO(2)、65%平衡 O(2)气体混合物的自我报告恐惧之间的关系，来检验该模型是否也适用于内脏威胁。样本由一大群年轻成年人（N=128）组成。结果表明，AC 调节了特质焦虑与对挑战的恐惧反应之间的关系。研究结果表明，AC 在调节自我报告的恐惧方面起着重要的、具有临床意义的作用。
