Abstract

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 worse 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.

摘要

本研究考察了睡眠与认知功能之间的个体内关系。50 名居住在社区的非裔美国人(年龄范围为 50-80 岁)被要求报告前一天晚上的睡眠时间和睡眠质量,并在 2-3 周内的 8 个场合完成认知测试。睡眠持续时间的个体内日常变化与整体认知表现较差显著相关。一个人在特定一天偏离其平均睡眠时间的幅度越大,他或她的表现下降的可能性就越大。这些结果表明,在个体内的分析水平上可以观察到睡眠与认知之间的关系。
