摘要：

目的：探讨小睡在连续40小时睡眠剥夺(sleepdeprivation，SD)条件下对连续计算能力的影响。方法：8名青年被试做自身前后对照，SD从第一天的6：00到第二天的22：00，共为40小时。小睡时间分别为每天13:00和1:00，共3次，每次30min，同时用脑电图监测。在实验开始前、第一天的13:00、18:00、第二天的1:00、6：00、13:00、18:00、22：00和恢复睡眠2天后分别测量连续计算，并记录反应时和错误数。结果：同基础值相比，SD后各点反应时延长(P<0.05），小睡组各点反应时延长，但没有统计学意义；各个SD时间点上，小睡组图形为平滑，而SD组在SD24h、SD31h和SD40h同小睡组相比反应时间显著增长(P<0.05）；同基础值相比，SD组和小睡组错误数没有显著增加，二组之间没有明显区别。结论：SD对连续计算的反应时有影响，小睡对反应时有一定的保护作用；SD对错误反应没有影响，小睡也没有保护作用。

Objective: To study the effect of 30-min nap at three low points of the rhythm during 40-hours sleep deprivation on continuous adding. Methods: Eight young subjects with normal sleep-wake habits were subjected to nap and total sleep deprivation conditions at an interval of 2 weeks. The whole experiment was from 6:00 of the first day to 22:00 of the second day, totally 40 hours. There were three times of nap which lasted 30 min every time, 13:00(the first day), 1:00 and 13:00(the second day). Continuous adding was given separately at the time before experiment,13:00 and 18:00 of the first day, 1:00,6:00,13:00,18:00 and 22:00 of the second day.and 2 days after the experiment;reaction times and wrong numbers were recorded. Results: Whether sleep deprivation with or without naps, the reaction time was prolonged.Compared with total sleep deprivation, the reaction time was shortened significantly at SD24, SD31 and SD40 when naps were introduced. Whether sleep deprivation with or without naps, the number of wrong answers did not change. Conclusion:Nap has positive effects during sleep deprivation.
