睡眠限制对记忆力及注意力影响

Effect of sleep restriction on concentration and memory diversification

目的通过观察测试者被睡眠限制2d后记忆和协调的作业能力影响,探讨使用记忆游戏和重复打字测试方法评估睡眠限制后的记忆力和注意力的变化。方法对煤炭医学院来我院实习的13名学生进行2夜睡眠限制,期间进行作业能力的6次测试。测试内容是记忆游戏和重复打字,将游戏得分和打字内容及数量分别作为记忆力和注意力测量值。对各组后5次测量值依次与第1次测量值进行配对t检验。结果A组第2～6次记忆游戏得分分别为(10397.78±2273.37),(12235.44±4064.64),(12938.44±1876.80),(11584.22±3238.18),(12038.00±3290.55)分,均低于第1次得分(17168.56±2992.58)分(P<0.05);B组第2～6次记忆游戏得分和第1次比较,差异均无统计学意义。A组中3～6次测试的重复打字正确率与第1次比较,差异均有统计学意义(P<0.05),其他3次与第1次比较,差异均无统计学意义。结论睡眠限制后测试者的记忆力和注意力变化可用记忆游戏和重复打字的测试方法进行评估。

Objective To evaluate the changes of the human memory and concentration after two nights of sleep restriction. Methods Twelve tests （6 memory tests and 6 typing tests） were conducted in two groups of medical students （n = 13） ,druing the 2 nights of sleep restriction. Scores of the memory game and quantity of the typing test were used for the memory and concentration evaluation. Coupling t analyses on the results of last 5 tests with that of first were conducted. Results There was significant difference in tests in tests＇ score between first test and the last 5 tests in A group （P 〈 0. 05）..There was no significant difference in group B（P 〉0. 05）. Conclusion Memory game and typing test can be used to evaluate the changes of human memory and concentration after two nights of sleep restriction.
