In this study, we investigated the effect of 24-h total sleep deprivation on subjective time perception. Twenty-five participants aged 18-35 years (13 female and 12 male) were recruited. Time perception and cognitive assessments were performed twice: after a regular night's sleep and following a 24-h sleep deprivation. The retrospective and prospective tasks were used to measure time perception. In order to prevent order effect, the test orders were randomized. The Stroop test and the Wechsler Memory Scale-III were used to evaluate attention, processing speed, and memory. The repeated measures ANOVA was used to examine gender-by-sleep deprivation interactions on time perception. We found that retrospective time perception was significantly prolonged after sleep deprivation (p < 0.05). Women had a shorter prospective time estimation rate after adequate sleep than men, but this difference disappeared after sleep deprivation. The Stroop test showed improvement in cognitive flexibility after sleep deprivation (p < 0.05), and short-term or working memory appeared unaffected by one night of sleep deprivation. There was a negative correlation between sleepiness rate and working memory function in female subgroup. The results suggest that even short-term sleep deprivation can significantly affect time perception, which may have important implications in critical situations.
在这项研究中，我们调查了 24 小时完全睡眠剥夺对主观时间感知的影响。招募了 25 名年龄在 18-35 岁的参与者（13 名女性和 12 名男性）。时间感知和认知评估进行了两次：一次是在正常的夜间睡眠后，一次是在 24 小时睡眠剥夺后。使用回溯和前瞻任务来测量时间感知。为了防止顺序效应，测试顺序是随机的。使用 Stroop 测试和韦氏记忆量表-III 评估注意力、处理速度和记忆。重复测量方差分析用于检验性别与睡眠剥夺对时间感知的交互作用。我们发现，睡眠剥夺后回溯时间感知显著延长（p<0.05）。女性在充足睡眠后前瞻性时间估计率比男性短，但睡眠剥夺后这种差异消失了。Stroop 测试显示认知灵活性在睡眠剥夺后有所改善（p<0.05），而短期或工作记忆不受一夜睡眠剥夺的影响。女性亚组的困倦率与工作记忆功能呈负相关。结果表明，即使是短期睡眠剥夺也会显著影响时间感知，这在关键时刻可能具有重要意义。
