There are few studies examining changes in waking function in a laboratory environment with no sleep deprivation and mood has been largely overlooked in this context. The present study examined changes in mood, performance, sleep and sleepiness in the laboratory study with no sleep deprivation. Nineteen participants (10M, 9F; 22 ± 4.2 years) were given nine 9-h sleep opportunities (23.00–08.00 hours). Every 2 h during wake, participants completed the Mood Scale II, a 10-min Psychomotor Vigilance Task and measures of sleepiness and fatigue. Sleep was monitored using an electroencephalographic montage. Findings revealed significant negative mood change, performance impairment, reduced total sleep time and sleep efficiency (all P < 0.05). These findings suggest that the laboratory environment or procedural factors may impair mood, performance and sleep. These findings may have implications for interpreting impairments in mood, performance and sleep when observed in laboratory environments.

在没有睡眠剥夺的实验室研究中，情绪、表现和睡眠会发生什么变化？

很少有研究在没有睡眠剥夺的实验室环境中检查清醒功能的变化，在这种情况下，情绪在很大程度上被忽视了。本研究在没有睡眠剥夺的实验室研究中检查了情绪、表现、睡眠和嗜睡的变化。19 名参与者（10M，9F；22 ± 4.2 岁）获得了 9 次 9 小时的睡眠机会（23.00-08.00 小时）。在醒来期间每 2 小时，参与者完成情绪量表 II，一项 10 分钟的精神运动警戒任务以及困倦和疲劳的措施。使用脑电图蒙太奇监测睡眠。结果显示显着的负面情绪变化、表现受损、总睡眠时间和睡眠效率减少（所有 P < 0.05）。这些发现表明实验室环境或程序因素可能会损害情绪，性能和睡眠。这些发现可能对解释在实验室环境中观察到的情绪、表现和睡眠障碍有影响。
