我们的目的是调查在60小时的完全睡眠剥夺期间，在2个晚上的恢复睡眠后，以及任务难度和/或主观嗜睡是否改变了自我监测的性能。40名成年人（22名女性，年龄19- 39岁）接受了为期5天的方案，其中休息良好的一天，66小时的总睡眠剥夺（最后一次测试时间为60小时），和2晚的8小时恢复睡眠。一项具有三个难度级别的算术任务（MATH）评估工作记忆。心理警觉任务评估持续的注意力。算术准确性和心理警戒任务的中位数反应时间测量客观性能。主观表现与自我报告的准确性和速度。自我监控能力的主观-主观差异评价。在完全睡眠剥夺期间，这两项任务的表现都有所下降，并在恢复后有所改善。在完全睡眠剥夺期间，参与者准确地自我监测了心理警戒任务的表现;然而，他们高估了数学的认知缺陷，自我报告的表现比实际观察到的更差。恢复后，参与者高估了在心理警戒任务上的表现改善程度。任务难度影响自我监控能力，随着难度的增加，在完全睡眠剥夺期间对表现缺陷的高估程度更大。主观嗜睡预测主观性能评级在几个时间点，只有心理警戒任务。在完全睡眠剥夺期间，工作记忆的自我监测能力受损，在恢复睡眠后，精神警觉任务的自我监测能力受损，但在其他方面是准确的。在操作环境中，自我监控策略的发展，评估主观感知的性能和主观嗜睡，可能有助于减少睡眠相关障碍的后果。
We aimed to investigate whether self-monitoring of performance is altered during 60h of total sleep deprivation, following 2nights of recovery sleep, and by task difficulty and/or subjective sleepiness. Forty adults (22 females, aged 19-39years) underwent a 5-day protocol, with a well-rested day, 66h total sleep deprivation (last test session at 60h), and 2nights of 8h recovery sleep. An arithmetic task (MATH) with three difficulty levels assessed working memory. The Psychomotor Vigilance Task assessed sustained attention. Arithmetic accuracy and Psychomotor Vigilance Task median reaction time measured objective performance. Subjective performance was measured with self-reported accuracy and speed. Objective-subjective differences assessed self-monitoring ability. The performance on both tasks declined during total sleep deprivation and improved following recovery. During total sleep deprivation, participants accurately self-monitored performance on the Psychomotor Vigilance Task; however, they overestimated cognitive deficits on MATH, self-reporting performance as worse than actually observed. Following recovery, participants overestimated the extent of performance improvement on the Psychomotor Vigilance Task. Task difficulty influenced self-monitoring ability, with greater overestimation of performance deficits during total sleep deprivation as difficulty increased. Subjective sleepiness predicted subjective performance ratings at several time points, only for the Psychomotor Vigilance Task. The ability to self-monitor performance was impaired during total sleep deprivation for working memory and after recovery sleep for the Psychomotor Vigilance Task, but was otherwise accurate. The development of self-monitoring strategies, assessing both subjective perceptions of performance and subjective sleepiness, within operational contexts may help reduce the consequences of sleep-related impairments.
