Mediators of estimates of brief time intervals in elderly domiciled males

Conflicting interpretations questioning whether brief intervals of real time are perceived as passing more or less rapidly with increasing age have been reported. Reasons for these inconsistent results lie in semantic confusions, in variations in methodology, and in the effects of other mediating variables. The present study examined relationships between age, value of time over both the short and the long term, perceived time to death, self-perceived activity levels, and estimates of brief time intervals in a sample of older institutionalized males. The production method was used to obtain the estimates of time passage. Time intervals were increasingly underestimated with advancing age, indicating that time units are shorter with increasing age. While a number of other variables were interrelated, the only other factor consistently related to time estimates was the short-term value of time. Implications for future research and for interventions in institutional settings are discussed.
