Associations among fluid and crystallized cognition and daily stress processes in older adults.

The current study examined associations among fluid and crystallized cognition, and daily stress processes in older adults. Older adults (N = 107) completed measures of daily stressors and affect on six occasions over 2 weeks, as well as measures of fluid and crystallized cognition. Higher crystallized cognition was associated with a greater likelihood of exposure to daily stressors, including arguments and avoided arguments. Higher fluid cognition was associated with diminished emotional reactivity to daily stressors for negative but not positive affect. Discussion focuses on the roles of fluid and crystallized cognition for understanding daily stress processes, daily activity and lifestyle, and health.
