Intra-Individual Variation in Working Memory Capacity Moderates Reactivity to Everyday Stressor Exposures

We conducted a measurement burst design study of intra-individual variation in working memory capacity and reactivity to everyday stressors (6 surveys/day over 7 days). Participants completed an ultra-brief ambulatory rotation span task during each survey. We observed greater stressor reactivity during moments with lower than average rotation span task performance.
