研究目的：为了评估睡眠剥夺对基于时间的前瞻性记忆表现的影响，即在未来的适当时间实现延迟的意图（例如，设计：被试间实验设计。实验组进行24 h的完全睡眠剥夺，对照组进行规则的睡眠-觉醒周期。参与者在08：00进行测试。设置：实验室。参与者：50名健康的年轻人（平均年龄22 +/- 2.1，31名女性）。干预措施：24小时的总睡眠剥夺。测量和结果：参与者在实验前3天通过腕动计进行监测。进行了以下认知任务：一个基于时间的前瞻性记忆任务和3个推理任务作为持续活动。客观和主观的警觉性进行了评估的心理警觉性任务和视觉模拟量表，分别。为了测量基于时间的前瞻性记忆任务，我们评估了依从性和时钟检查行为（时间监测）。睡眠剥夺对基于时间的前瞻性记忆依从性（P < 0.001）、客观警觉性（平均RT：P < 0.001;最慢10% RT：P < 0.001;失误：P < 0.005）和主观警觉性（P < 0.0001）产生负面影响。推理任务和时间监测行为的表现没有不同groups.Conclusions：结果突出了潜在的危险影响，总的睡眠剥夺对人类的行为，特别是能够执行一个预期的行动后，几分钟。睡眠剥夺严重损害基于时间的前瞻性记忆的依从性，但不影响时间检查频率。睡眠剥夺可能会损害允许整合与时间监测相关的信息与前瞻性意图的机制。
Study Objectives: To evaluate the effect of sleep deprivation on time-based prospective memory performance, that is, realizing delayed intentions at an appropriate time in the future (e.g., to take a medicine in 30 minutes).Design: Between-subjects experimental design. The experimental group underwent 24 h of total sleep deprivation, and the control group had a regular sleep-wake cycle. Participants were tested at 08:00.Settings: Laboratory.Participants: Fifty healthy young adults (mean age 22 +/- 2.1, 31 female).Interventions: 24 h of total sleep deprivation.Measurements and Results: Participants were monitored by wrist actigraphy for 3 days before the experimental session. The following cognitive tasks were administered: one time-based prospective memory task and 3 reasoning tasks as ongoing activity. Objective and subjective vigilance was assessed by the psychomotor vigilance task and a visual analog scale, respectively. To measure the time-based prospective memory task we assessed compliance and clock checking behavior (time monitoring). Sleep deprivation negatively affected time-based prospective memory compliance (P < 0.001), objective vigilance (mean RT: P < 0.001; slowest 10% RT: P < 0.001; lapses: P < 0.005), and subjective vigilance (P < 0.0001). Performance on reasoning tasks and time monitoring behavior did not differ between groups.Conclusions: The results highlight the potential dangerous effects of total sleep deprivation on human behavior, particularly the ability to perform an intended action after a few minutes. Sleep deprivation strongly compromises time-based prospective memory compliance but does not affect time check frequency. Sleep deprivation may impair the mechanism that allows the integration of information related to time monitoring with the prospective intention.
