Daily memory lapses in older adults are primarily related to between-person differences in cognitive performance, health, and age awareness, rather than short-term daily fluctuations. These findings suggest that stable individual differences, rather than day-to-day changes, are most predictive of daily memory lapses. Day-to-day variations in memory lapses may instead be influenced by factors not captured in the present study, such as fatigue, stress, distraction, or mood.
