Abstract为探讨不同睡眠剥夺(sleep deprivation,SD)时间对于警觉性的影响,将24名正常青年男性分为SD21h组、SD45h组、SD69h组,每组8名,主要应用三个字母(C、G、N)的划销测验来测查不同SD条件下的警觉能力。测试时间分别为每天的7:00、10:00、13:00、16:00、19:00、22:00、1:00、4:00,采用组间比较和自身前后比较。结果:SD后,完成时间、总击中数、假阳性数和倒数第二分钟击中数表现出成绩显著下降,并同SD时间有关; 完成时间和总击中数表现出生物节律的作用; 倒数第二分钟击中数同SD相关系数最高,为非常好地评定警觉性的指标。结论:SD后警觉水平下降,并且同SD时间长短有关; SD时,字母划销测验是非常好的测查警觉性的测验。

NoteObjective: To study the effects of sleep deprivation on vigilance.Method: 24 young males with normal sleep-wake habits were divided into SD21h group,SD45h group,SD69h group,8 each group.3-letters cancellation test was introduced to test the vigilance at 7:00,10:00,13:00,16:00,19:00,22:00,1:00 and 4:00 of each day.Results: After SD,the results of completing time,total number of hits,number of false positives and the number of hits of the second last minute declined and were correlated with duration of sleep deprivation.The results of completing time and total number hits showed the effect of rhythm.The number of hits of second last minute had the highest correlation,and it's the perfect index to assess vigilance.Conclusions: Vigilance level declines after SD and is correlated with the duration of SD.LCT is a favorable test to assess vigilance.
