目的 :探讨小睡对连续 4 0小时睡眠剥夺的应对作用。方法 :8名青年被试做自身前后对照 ,睡眠剥夺时间从第一天的 6 :0 0到第二天的 2 2 :0 0 ,共为 4 0小时 ,在实验过程中给予打字的工作负荷。小睡时间分别为每天中午的 1 3:0 0和晚间的 1 :0 0 ,共 3次 ,每次 30分钟 ,同时用脑电图进行监测 ,在晚间1 :0 0和实验结束时分别测量视觉事件相关电位。并且在实验开始前、实验结束后 2天和每次小睡后 30分钟后测量划消测验。结果 :无论是睡眠剥夺组还是加入小睡组 ,被试的作业反应时延长、正确数降低 ,漏划数增加。同完全睡眠剥夺相比 ,加入小睡后 ,被试划消测验的反应时明显缩短 ,正确数及漏划数无明显变化。无论是睡眠剥夺组还是加入小睡组 ,实验结束后两天的恢复值同实验前相比无明显差异。睡眠剥夺组的P30 0潜伏期明显延长 ,正确率降低 ,但振幅无明显变化。加入小睡后P30 0潜伏期明显缩短 ,正确率、振幅没有明显变化。结论 :小睡对睡眠剥夺有一定的应对作用
Objective: To investigate the response of napping to sleep deprivation for 40 consecutive hours. Methods: Eight young subjects were compared before and after their self-control. The sleep deprivation time ranged from 60:40 on the first day to 22:02 on the next day, for a total of 40 hours. The working load was typed during the experiment . Snooze time was 1: 00 at noon every day and 1: 0 at night, 3 times for 30 minutes each time. EEG was used for monitoring, visual acuity was measured at 1: 0 in the evening and at the end of the experiment Event related potential. And the decontamination test was measured before the start of the experiment, 2 days after the end of the experiment, and 30 minutes after each nap. Results: Whether sleep deprivation group or napping group, subjects’ reaction time prolonged, the correct number decreased and the number of missed drafts increased. Compared with complete sleep deprivation, after taking a nap, the reaction time of the test de-test significantly shortened, the correct number and the number of missing no significant change. No matter in sleep deprivation group or napping group, the recovery value of the two days after the end of the experiment had no significant difference compared with that before the experiment. Sleep deprivation group P30 0 latency was significantly longer, the correct rate decreased, but no significant changes in amplitude. Add P30 after napping latency was significantly reduced, the correct rate, amplitude no significant change. Conclusion: Naps have a certain response to sleep deprivation
