Three experiments were conducted to investigate the mediating effect of attentional bias on the relationship between state anxiety and time perception. In Experiment 1, state anxiety (high and low) was manipulated by a standardized induction procedure, attentional bias was tested by a dot-probe task, and time perception of words (negative and neutral) was tested by a time reproduction task in which a standard duration of 2 s was used. In Experiment 2, multiple durations (2, 4, and 8 s) were tested within subjects, and negative and neutral low-arousal pictures were selected for the dot-probe task and the time reproduction task. In Experiment 3, attentional bias was manipulated by an attentional bias modification training to test the causal relationship between attentional bias and time perception. The results suggested that (a) participants in an anxious state showed an attentional bias toward negative stimuli and perceived a 2-s duration as longer when stimuli were negative as opposed to when they were neutral, (b) attentional bias toward negative stimuli mediated the influence of state anxiety on time perception, and (c) attentional bias had a direct impact on time perception. Our findings contribute to the understanding of the role that attention plays in how individuals perceive time in an anxious state and provide novel evidence supporting the attentional gate model.

三项实验旨在探讨注意偏向在状态焦虑与时间知觉关系中的中介作用。在实验 1 中,通过标准化的诱导程序来操纵状态焦虑(高和低),通过点探测任务来测试注意偏向,通过时间复制任务来测试单词(负性和中性)的时间知觉,其中使用了 2 秒的标准持续时间。在实验 2 中,对多个时间(2、4 和 8 秒)进行了被试内测试,并且选择了负性和中性低唤醒图片用于点探测任务和时间复制任务。在实验 3 中,通过注意偏向修正训练来操纵注意偏向,以检验注意偏向和时间知觉之间的因果关系。结果表明:(a) 焦虑状态下的参与者对负性刺激表现出注意偏向,并且当刺激为负性而非中性时,他们会将 2 秒的持续时间感知为更长;(b) 对负性刺激的注意偏向中介了状态焦虑对时间知觉的影响;(c) 注意偏向对时间知觉有直接影响。我们的研究结果有助于理解在焦虑状态下个体如何感知时间,注意力所起的作用,并为注意门模型提供了新的支持证据。
