在这里，我们使用时间知觉的注意门模型(AGM)的预测，在焦虑(n=29)和非焦虑(n=29)个体中探讨了暴露于威胁刺激和中性刺激对时间知觉的影响。结果表明，与不焦虑的个体相比，焦虑的个体在短时间(2秒)的威胁刺激下主观上感觉到时间移动得更慢，并且随着暴露时间的延长(4秒和8秒)，群体差异消失。再加上焦虑个体在压力下对威胁的注意偏向增强和注意力控制减弱的经典报告，这一发现为塑造和维持焦虑的主观体验的低水平认知过程提供了新的见解。研究结果与年度股东大会的预测和对焦虑的认知解释有关。
Here, we explored the effect of exposure to threat versus neutral stimuli on time perception in anxious (n=29) and non-anxious (n=29) individuals using predictions from the attentional gate model (AGM) of time perception. Results indicate that relative to non-anxious individuals, anxious individuals subjectively experience time as moving more slowly when exposed to short (2-second) presentations of threat stimuli, and that group differences disappear with longer exposure durations (4 and 8 seconds). Coupled with classic reports of enhanced attentional bias toward threat and diminished attentional control under stress in anxious individuals this finding provides novel insights into low-level cognitive processes that could shape and maintain the subjective experience of anxiety. Findings are discussed in relation to predictions from the AGM and cognitive accounts of anxiety.
