摘　　要：目的探讨睡眠剥夺对健康人注意力的影响。方法对10名健康青年男性志愿者进行32h(第1d8:00～第2d16:00)睡眠剥夺,并在睡眠剥夺前、后各17h和32h分别进行4次持续性操作任务(CPT)、选择性注意力(Stroop测验)的测试。结果在CPT和Stroop试验测试中,睡眠剥夺后2次测试的反应时间显著长于睡眠剥夺前,错误率显著高于睡眠剥夺前(均P<0.05),睡眠剥夺后第2次测试平均反应时间和错误率较第1次测试显著增加(均P<0.05)。结论健康人睡眠剥夺后注意力明显下降,并且睡眠剥夺时间越长越明显。Objective To observe the effect of attention after sleep deprivation in healthy volunteers. nethods10 healthy young male volunteers were exposed to continuous sleep deprivation for 32 h. Continuous performance task（CPT） and Stroop tests were performed 4 times to the volunteers at 17 h and 32 h before and after sleep deprivation. Results In CPT and Stroop test, the total reaction time and error rate were elevated significantly after sleep deprivation （ all P 〈 0. 05 ）, and the average reaction time and error rate of the second test were elevated significantly compared with the first test after sleep deprivation （all P 〈 0. 05 ）. Conclusion The attention is decreased after sleep deprivation significantly in healthy volunteers, and the longer sleep deprivation time, the more obvious.
