摘　　要：目的比较3 700m海拔驻防3个月与15个月军人认知功能的变化。方法采用自身前后配对设计,对22名驻防3 700m海拔3个月与15个月两个驻防时长男性新兵的8项认知功能指标进行对比研究,包括反应运动时、速度知觉、时间知觉、深度知觉、手臂稳定性、记忆广度、短时记忆、注意广度。结果男性新兵在3 700m海拔驻防15个月后,相比于3个月驻防时长,反应时延长(P<0.05),手臂稳定性下降(P<0.05),记忆力提高(P<0.05),深度知觉容易出现"看近"现象(P<0.05)。结论与3个月相比,15个月的高海拔驻防更为明显地损伤了军人的反应时、深度知觉、动作稳定性及注意广度。Objective To compare the cognitive function changes of newly-recruited male soldiers after exposure to 3 700 m altitude for 3months and 15 months.Methods Using＂pretest-posttest design＂,we selected 22newly-recruited male soldiers in this experiment,and 8 cognitive function variables,namely,the reaction and motion time,speed-perception,timeperception,depth-perception,operating-dexterity,memory span,short-term memory and attention span were analyzed by paired comparison for 3months and 15 months.Results Compared with soldiers exposed for 3months,those exposed for 15 months had significantly increased reaction time（P〈0.05）,significantly decreased operating-dexterity performance（P〈0.05）,and significantly improved memory（P 0.05）.The depth-perception was more liable to have the ＂see close＂phenomenon.Conclusion Compared to those exposed to high altitude environment for 3months,newly-recruited male soldiers exposed for 15 months have a more apparent damage to the reaction time,depth-perception,operating-dexterity and attention.
