目的：这项研究检查了日常认知是否存在日常波动，这与传统的基本认知能力测量中经常观察到的日常波动一致。方法：206名独立生活的老年人（年龄范围= 60-91岁）被要求在2- 3周内完成8次计算机认知电池。结果如下：使用多水平模型，在日常日常认知评估（DECA; 46%）中观察到显著的人内变异性，人与人之间变异性为54%。在每一种情况下，在DECA上表现更好的人在简单反应时间（p <0.01）和记忆（听觉言语学习任务，p <0.01）上的表现都与更好的表现显著相关，即使在考虑了时间、年龄、教育和其他认知指标的表现之后。结论：这些发现表明，在日常认知任务中可以观察到人内表现波动，这些波动与基本认知能力的日常变化一致。
Objective: This study examined whether there are daily fluctuations in everyday cognition that are consistent with daily fluctuations often observed in traditional measures of basic cognitive abilities. Method: Two hundred six independently living older adults (age range = 60-91 years) were asked to complete a computerized cognitive battery over eight occasions within a 2- to 3-week period. Results: Using multilevel model, significant within-person variability was observed across the Daily Everyday Cognition Assessment (DECA; 46%), with 54% between-person variability. At each occasion, better performance on the DECA was significantly associated with better performance on simple reaction time ( p < .01) and memory (Auditory Verbal Learning Task, p < .01) even after accounting for time, age, education, and performance on other cognitive measures. Conclusion: These findings demonstrate that within-person performance fluctuations can be observed for everyday cognition tasks, and these fluctuations are consistent with daily changes in basic cognitive abilities.
