昼夜节律和睡眠/觉醒依赖过程的变化，在主观警觉性和认知性能进行了评估，在一个恒定的常规协议，并在协议中，其中的睡眠/觉醒周期是解耦的内源性昼夜节律起搏器的输出。在后一种方案中，通过在睡眠/觉醒周期或内源性昼夜体温节律周期折叠数据来分离睡眠/觉醒依赖性过程和昼夜过程对警觉性和表现的贡献。该分析显示，在0-18小时范围内的先前觉醒显著降低了警觉性和表现，并且核心体温的昼夜节律与警觉性和表现的昼夜节律相一致。在第一个16小时的恒定常规协议，这与受试者的习惯性觉醒期，警觉性和性能保持在一个稳定的水平。后一个发现是通过假设在我们通常清醒的日子里，昼夜节律系统抵消了先前清醒时间增加的有害影响来解释的。
Circadian and sleep/wake dependent processes underlying variations in subjective alertness and cognitive performance were assessed in a constant routine protocol and in a protocol in which the sleep/wake cycle was uncoupled from the output of the endogenous circadian pacemaker. In the latter protocol, the contribution of a sleep/wake dependent process and a circadian process to alertness and performance were separated by folding the data at either the period of the sleep/wake cycle or at the period of the endogenous circadian body temperature rhythm. This analysis revealed that prior wakefulness within a range of 0-18 h significantly reduced alertness and performance and that the circadian rhythm of core body temperature paralleled the circadian rhythm of alertness and performance. During the first 16 h of the constant routine protocol, which coincided with the subjects' habitual period of wakefulness, alertness and performance remained at a stable level. The latter finding was explained by assuming that during our usual waking day the circadian system counteracts the detrimental effects of increasing duration of prior wakefulness.
