title: The stability of time estimation in older adults.
abstract: The ability to correctly estimate time is important for many daily activities, such as cooking and driving. This study investigated the stability time estimation in healthy older adults and compared them to healthy younger adults. Participants were tested and retested across the duration of 1 year. Using a prospective paradigm, verbal estimates were provided for intervals of 10, 25, 45, and 60 seconds. Although the older adults demonstrated a greater magnitude of error in their time estimates than younger adults, their time estimates remained stable across the 1-year duration. This suggests that instability in time estimates across two time points is unlikely to account for the discrepant task findings in the aging and verbal time estimation literature.
