睡眠剥夺对内隐记忆的影响

目的:探讨不同时间睡眠剥夺(sleep deprivation,SD)对内隐记忆的影响。方法:将32名青年男性随机分为4组:对照组、SD21、SD45和SD69组,每组8名。采用补笔测验和组词测验对4组被试进行测试。结果:SD 后无论知觉启动还是语义启动,启动量降低,并随SD 时间延长而减少。同一组内,两种测验进行比较,除对照组外,其他SD 组两两比较,语义启动的启动量大于知觉启动(P<0.05)。知觉启动中,SD45同SD69 相比无显著差异(P=0.245),其他两两比较差异均有统计学意义(P<0.01);语义启动中,SD21同对照组相比差异无统计学意义(P=0.316),其他两两比较差异均有统计学意义(P<0.01)。结论:SD 后内隐记忆受损,并同SD 时间有关;SD 后语义启动和知觉启动出现分离,知觉启动更受SD 影响。

Effects of Sleep Deprivation on Implicit Memory

Objective:To investigate the effects of sleep deprivation(SD)on implicit memory.Methods:32 young men were divided into four groups,SD21,SD45,SD69 and Control,8 men each group.Subjects were asked to finish the tests of word completion and words association.Results:After SD,both semantic priming and perceptual priming decreased significantly and the decrease were connected with the length of SD.In the same group,the decrease of perceptual priming of SD groups was significantly lowered than that of semantic priming.In perceptual priming,there was significantly different compared between groups except that of SD45 and SD69.In semantic priming,there was significantly different compared between groups except that of Control and SD21.Conclusions: SD has effect on implicit memory,and it's associated with the length of SD.After SD,there exits dissociation between semantic priming and perceptual priming.Perceptual priming is more affected.
