本研究评估了警觉性、记忆力和表现，与8小时卧床（TIB）睡眠计划相比，这三种计划类似于8小时睡眠损失（缓慢、中等和快速积累）。12名年龄在21-35岁的健康个体根据拉丁广场设计完成了四种条件中的每一种：无睡眠损失（8小时TIB持续4晚；2300-0700），缓慢（6小时TIB持续4晚；0100-0700），中度（4小时TIB持续2晚；0300-0700）和快速（0小时TIB持续1晚）睡眠损失。每天，参与者都要完成多次睡眠潜伏期测试（MSLT）、探查回忆记忆任务、精神运动警戒任务、分散注意力任务和情绪状态描述。在警觉性、记忆力和表现测试中，“快速”睡眠缺失明显比“缓慢”积累相当数量的睡眠缺失造成更大的损害。睡眠缺失的损害效应随睡眠频率的变化而变化，这表明存在一种与睡眠债务积累相关的补偿性适应机制。
The present study assessed alertness, memory, and performance following three schedules of similar to8 hr of sleep loss (slow, intermediate, and rapid accumulation) in comparison to an 8-hr time in bed (TIB) sleep schedule. Twelve healthy individuals aged 21-35 completed each of four conditions according to a Latin Square design: no sleep loss (8-hr TIB for 4 nights; 2300-0700), slow (6-hr TIB for 4 nights; 0100-0700), intermediate (4-hr TIB for 2 nights; 0300-0700), and rapid (0-hr TIB for 1 night) sleep loss. On each day, participants completed a multiple sleep latency test (MSLT), a probed-recall memory task, a psychomotor vigilance task, a divided attention task, and the Profile of Mood States. "Rapid" sleep loss produced significantly more impairment on tests of alertness, memory, and performance compared to the "slow" accumulation of a comparable amount of sleep loss. The impairing effects of sleep loss vary as a function of rate, suggesting the presence of a compensatory adaptive mechanism operating in conjunction with the accumulation of a sleep debt.
