Distortions of duration perception are often observed in response to highly arousing stimuli, but the exact mechanisms that evoke these variations are still under debate. Here, we investigate the effect of induced physiological arousal on time perception. Thirty-eight university students (22.89 ± 2.5; 28 females) were tested with spontaneous finger-tapping tasks and a time bisection task (with stimuli between 300 and 900 ms). Before the time bisection task, half of the participants (STRESS group) performed a stress-inducing task, i.e., the Paced Auditory Serial Addition Test (PASAT), whereas the other participants (CONTROL group) performed a control task, the Paced Auditory Number Reading Task (PANRAT). The PASAT induced a greater heart rate, but not electrodermal, increase, as well as a more unpleasant and arousing state compared to the PANRAT. Moreover, although the two groups presented a similar performance at the finger-tapping tasks, participants in the STRESS group showed better temporal performance at the time bisection task (i.e., lower constant error) than the controls. These results indicate that psychophysiological stress may alter the subsequent perception of time.
时长感知的扭曲经常在对高度刺激的反应中观察到，但引起这些变化的确切机制仍存在争议。在这里，我们研究了诱导的生理唤醒对时间感知的影响。三十八名大学生（22.89±2.5；28 名女性）接受了自发手指敲击任务和时间二分任务（刺激时间为 300 到 900 毫秒）的测试。在时间二分任务之前，一半的参与者（应激组）进行了一项引起应激的任务，即定时听觉连续加法测试（PASAT），而其他参与者（对照组）进行了一项控制任务，即定时听觉数字阅读测试（PANRAT）。与 PANRAT 相比，PASAT 引起了更大的心率和皮肤电增加，以及更不愉快和更兴奋的状态。此外，尽管两组在手指敲击任务中的表现相似，但应激组的参与者在时间二分任务中的时间表现更好（即更低的恒定误差），而对照组则不然。这些结果表明，心理生理应激可能会改变随后的时间感知。
