摘　　要：目的:探讨36 h完全睡眠剥夺(total sleep deprivation,TSD)对青年人客体和自我旋转能力影响的差异。方法:对12名健康青年军人,在36 h TSD前后进行客体和自我心理旋转任务时进行事件相关电位测定,测量P500的潜伏期、波幅。结果:在客体旋转方面,与TSD前相比,TSD 36 h正像波幅差异不显著(P>0.05),镜像波幅[(6.2±2.4)μV vs.(7.1±2.6)μV]降低,正像[(475.1±24.4)msvs.(463.4±24.2)ms]与镜像潜伏期[(486.3±23.1)ms vs.(475.4±22.4)ms]均延迟(P<0.05)。在自我旋转方面,与TSD前相比,TSD 36 h左手[(5.2±2.4)μV vs.(7.6±2.5)μV]、右手[(5.6±2.3)μV vs.(7.7±2.2)μV]波幅均降低(P<0.05),左手[(533.8±36.1)ms vs.(503.7±29.4)ms]、右手[(522.6±35.3)ms vs.(501.4±34.1)ms]潜伏期均延迟(P<0.05)。与TSD前相比,TSD36 h客体旋转潜伏期延迟值、波幅降低值均低于自我旋转(P<0.05)。结论:36 h完全睡眠剥夺可能会损害青年军人的心理旋转能力,对客体旋转能力的损伤程度小于自我旋转。提示在从事需睡眠剥夺的作业任务时,需在剥夺时间加以控制和在任务类型上加以区分。Objective： To explore the differential effect of 36 h total sleep deprivation （TSD） on object and self mental rotation in young adults. Methods： Twelve young healthy soldiers were recruited in the study and completed object and self mental rotation tests just before and after 36 h TSD. The event-related potentials were recorded when they did tests and the latency and amplitude of PS00 was analyzed. Results： In object rotation, compared with before TSD, after TSD 36 h the PS00 amplitude in normal did not show significant difference （P 〉0. 05）, the PS00 amplitude in mirror was significantly lower [（6. 2 22. 4）μV vs. （7. 1 22.6）μV, P 〈0. 05], and PS00 latencies in normal [ （475. 1 ± 24.4） ms vs. （463.4 ± 24. 2） ms] and mirror [ （486. 3 ± 23.1 ） ms vs. （475.4 ± 22.4） ms] were both significantly longer （Ps 〈 0. 05）. In self rotation, compared with before TSD, after TSD 36 h the PS00 amplitudes in left hand [（5.2 ±2. 4） μV vs. （7. 6 22. 5） /±V] and right hand [（5.6 ±22. 3） μV vs. （7.7 ± 2. 2）μV] were both significantly lower （P 〈0. 05）, and P500 latencies in left hand [（533, 8 ±36. 1） ms vs. （503.7 ±29.4） ms] and right hand [ （ 522. 6 ± 35.3） ms vs. （ 501.4 ± 34. 1 ） ms] were both significantly longer （ P 〈 0. 05）. Compared with before TSD, the delay value of latencies and reduced value of amplitudes in object rotation were significantly lower than those in self rotation after TSD 36 h （P 〈 0. 05）. Conclusion： It suggests that 36 h total sleep deprivation may harm the ability of mental rotation in a certain extent in young soldiers, and the extent of the damage in the ability of object rotation is less than self rotation＇s. It is necessary to be distinguished on different types of tasks and be controlled in the sleep deprivation time in the task with sleep deprivation.
