DESCRIPTION (provided by applicant): The broad aim of this application is to examine circadian timing and daytime function in high school students in the context of weekend recovery sleep behavior. Large disparity between school night and weekend night sleep timing is associated with poor daytime function (e.g., poor academic grades and depressed mood). The first aim of this study is to examine circadian factors that may contribute to this association. Modifying sleep patterns on the weekend to maintain stable circadian timing may attenuate daytime function decrements. Thus, the second aim of this study is to test an alternative weekend sleep schedule that stabilizes the circadian system. The proposed study uses a within subjects counterbalanced design with two conditions that differ only by the following enforced weekend sleep/wake schedules: the commonly observed, late rise time schedule and an alternative schedule with stable nocturnal sleep and an afternoon nap. Circadian phase, subjective sleepiness, cognitive throughput, mood, and vigilance assessments precede and follow each weekend condition. This study may further the understanding of risk factors for poor daytime function and will evaluate sleep behaviors that may attenuate these decrements in teens.

描述（由申请人提供）：本申请的主要目的是在周末恢复睡眠行为的背景下检查高中生的昼夜节律和白天功能。学校晚上和周末晚上睡眠时间之间的巨大差异与白天功能不佳（例如，学业成绩差和情绪低落）有关。这项研究的首要目的是检查可能促成这种关联的昼夜节律因素。改变周末的睡眠模式以保持稳定的昼夜节律可能会减轻白天功能的下降。因此，这项研究的第二个目的是测试稳定昼夜节律系统的替代周末睡眠时间表。拟议的研究采用受试者内部平衡设计，有两种条件，其区别仅在于以下强制周末睡眠/唤醒时间表：常见的晚起时间表和具有稳定夜间睡眠和下午小睡的替代时间表。每个周末状况之前和之后都会进行昼夜节律阶段、主观困倦、认知吞吐量、情绪和警惕性评估。这项研究可能会进一步了解导致白天功能不佳的风险因素，并将评估可能减轻青少年这些功能下降的睡眠行为。
