Maintaining accurate and precise temporal perception under conditions of stress is important. Studies in animal models and clinic patients have suggested that time perception can change under chronic stress. Little is known, however, about the relationship between chronic stress and time perception in healthy individuals. Here, a sample of 62 healthy young men completed Cohen's Perceived Stress Scale (PSS) as a measure of chronic stress levels, while time perception was measured using a temporal bisection task. This task used short (400 ms) and long (1600 ms) visual signals as anchor durations. Participants were presented with a range of intermediate probe durations and were required to judge whether the durations were more similar to the short or the long anchor. Results showed that chronic stress was negatively related to temporal sensitivity indexed by the Weber ratio. However, there was no significant correlation between chronic stress and subjective duration indexed by the bisection point. These results demonstrate that higher chronic stress is associated with lower temporal sensitivity and thus provide evidence for a link between chronic stress and time perception in healthy adults.
在压力条件下保持准确和精确的时间感知很重要。对动物模型和临床患者的研究表明，在慢性压力下时间感知可能会发生变化。然而，对于健康个体中慢性压力与时间感知之间的关系，人们知之甚少。在此，62名健康年轻男性的样本完成了科恩感知压力量表（PSS），作为慢性压力水平的一种衡量指标，同时使用时间二分任务来测量时间感知。该任务使用短（400毫秒）和长（1600毫秒）的视觉信号作为锚定持续时间。向参与者呈现一系列中间探测持续时间，并要求他们判断这些持续时间与短锚定还是长锚定更相似。结果表明，慢性压力与由韦伯比率索引的时间敏感性呈负相关。然而，慢性压力与由二分点索引的主观持续时间之间没有显著相关性。这些结果表明，较高的慢性压力与较低的时间敏感性相关，从而为健康成年人中慢性压力与时间感知之间的联系提供了证据。
