摘要
在处理突发事件中睡眠剥夺会带来安全隐患,该项研究旨在探讨人体在40 h急性睡眠剥夺条件下情绪和认知自稳态调节过程。24名健康青年男性自愿参加40 h急性睡眠剥夺,采用每4 h一次的情绪量表和认知任务测评,监测数据变化。结果显示:40 h睡眠剥夺状态下,个体"警觉性"、"精力"下降,"思睡感""易怒"增强,不同时间点之间有显著性差异,而其他情绪相对稳定;认知作业提示,正确率非线性改变,受生物节律影响,不同时间点差异显著性,而连续相加认知成绩有上升趋势。同时表明:在40 h急性的睡眠剥夺中存在自稳态调节,虽然警醒度明显下降,但除"易怒"外情绪状态在一定程度上保持平稳;对要求高注意力快速反应的认知任务影响较大,而需要更多智力成份的认知能力,不仅没有受到影响,反而有所促进。
A test with 24 healthy young men participating in was conducted so as to investigate people＇ s self-stability adjustment of emotion and cognition in 40-hour acute sleep deprivation, in this test, the emotion and cognition state was measured for each 4 hours to monitoring the change of the data. The result shows that the individual＇ s ＂alert＂ and ＂energy＂ decrease and the ＂sleepiness＂ and ＂irritation＂ increase, there is a big difference in these aspects at different intervals, but a relative stability in other emotions. The correct rate of recognition work changes in non-linear way and is influenced by biothythm. It also shows that there is self-stability adjustment for other emotions in 40-hour acute sleep deprivation except alert and irritation; there is a big influence on the cognition work needing high attention and quick response, and a promotion to the cognitive ability needing more intelligence.
