Description
Tian Qiu, Daniel Elbich, Jessie Alwerdt, and Jonathan Hakun test whether sitting harms thinking differently depending on the timescale. They combined two weeks of ecological momentary assessment with thigh-worn activity monitors in 161 adults aged nineteen to eighty-eight. Cognition was probed six times daily with ultra-brief processing speed and working memory tasks.
Moment to moment, more sedentary time meant slower processing speed for participants over sixty-five, and swapping sitting for walking or standing helped briefly. Across days, however, more sedentary days came with better processing speed and working memory in both age groups. Cross-sectionally there was no association at all. The authors argue sedentary behavior's cognitive effects flip sign with timescale, complicating blanket advice.
