A continuous-time approach to short-term activity-cognition dynamics.

Abstract

= 44.67, 92% non-White). Replicating the older adult findings, moments dominated by passive activities showed beneficial within-person cross-effects on subsequent processing speed, alongside negatively correlated random fluctuations. In contrast, between-person associations indicated that greater engagement in passive activities was related to better working memory. Overall, these findings demonstrate short-term activity-cognition cross-effects while underscoring their complexity, as associations may differ across timescales and life stages.
