摘要：

This study examined the within person relationship between sleep and cognitive functioning Fifty community dwelling African Americans (age range = 50-80 years) were asked to report their sleep duration and quality the previous evening and to complete cognitive measures over 8 occasions within a 2-3 week period A within person daily change in sleep duration was significantly associated with woise global cognitive performance The greater an individual deviated away from his or her average sleep duration on a particular day the more likely his or her performance would decline These results demonstrate that the sleep cognition relationship can be observed at a within person level of analysis
