ABSTRACT
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.
