The aim of the present study was to deepen knowledge about the effect of a lowered vigilance state on time-based prospective memory (TBPM) performance. For this purpose 2 TBPM tasks (primary and interpolated), which shared a portion of the retention interval, and 3 reasoning tasks, as ongoing activities, were administered after total sleep deprivation and in a regular sleep condition. The results showed a detrimental effect of sleep deprivation on prospective memory performance and a partial dissociation between clock-checking behavior and time estimation for prospective compliance. This study clearly indicates that total sleep deprivation im- pairs the ability to complete multiple prospective task assignments in a timely fashion. Results are discussed suggesting the existence of different mechanisms involved in time monitoring and other cognitive functions underlying TBPM performance.

睡眠丢失对基于双时间的预期记忆任务的影响。

本研究的目的是加深有关警惕状态降低对基于时间的预期记忆（TBPM）性能的影响的知识。为此目的，共有2个TBPM任务（主要任务和内插任务）共享了一部分保留间隔，并且在进行完全睡眠剥夺并处于常规睡眠条件下，管理了3个推理任务（作为正在进行的活动）。结果表明，睡眠剥夺对预期的记忆表现有不利影响，时钟检查行为和预期依从性的时间估计之间存在部分分离。这项研究清楚地表明，睡眠不足会影响及时完成多项预期任务的能力。
