This study investigated the effects of self-awakening on daytime sleepiness. Eleven undergraduate and graduate students without the habit of self-awakening participated. They were instructed to follow their usual sleep-wake schedule at home during the experimental weeks and were required to awaken at their usual time by themselves every morning for one week without the aid of an alarm (self-awakening condition) or in response to a telephone call from the experimenter every morning for another one week (forced-awakening condition). On the last day of each week, daytime tests were conducted in the laboratory. The participants would arrive at the laboratory 2 h after awakening, and 1 h later, they performed the auditory simple reaction time task, the digit-symbol substitution task, the letter cancellation test, and the multiple sleep latency test, and assessment of sleepiness, fatigue, comfort, and work motivation every 2 h. In the week when the participants underwent the self-awakening condition, self-awakening had a higher success rate (82%) than failure rate (18%) on the seventh day. In comparison with forced-awakening, self-awakening resulted in an improvement in subjective fatigue; however, sleepiness did not deteriorate.
本研究调查了自我唤醒对日间嗜睡的影响。11名没有自我唤醒习惯的本科生和研究生参与了研究。在实验周期间，他们被要求在家遵循平常的睡眠-清醒时间表，并且在一周时间内每天早上不借助闹钟自行在平常时间醒来（自我唤醒条件），或者在另外一周时间内每天早上响应实验者的电话叫醒（强制唤醒条件）。在每周的最后一天，在实验室进行日间测试。参与者在醒来2小时后到达实验室，1小时后，他们进行听觉简单反应时间任务、数字-符号替换任务、字母划消测试和多次睡眠潜伏期测试，并每2小时评估嗜睡、疲劳、舒适度和工作动机。在参与者处于自我唤醒条件的那一周，第七天自我唤醒的成功率（82%）高于失败率（18%）。与强制唤醒相比，自我唤醒导致主观疲劳有所改善；然而，嗜睡并未恶化。
