This project examines whether day-to-day variation in self-reported screen time is associated with cognitive performance in adults’ daily lives. Using a 10-day ecological momentary assessment burst, the study distinguishes within-person fluctuations in screen exposure from between-person differences in average screen exposure and examines their associations with processing speed and visuospatial working memory.
Methods / Approach: Ecological momentary assessment; measurement-burst design; ambulatory cognitive assessment; day-level screen-time summaries; lagged autoregressive multilevel modeling; within-person and between-person decomposition
Output: Manuscript under preparation for journal submission.
