Executive functioning and processing speed in age-related differences in time estimation: a comparison of young, old, and very old adults

Résumé

Age-related differences in time estimation were examined by comparing the temporal performance of young, young–old, and old–old adults, in relation to two major theories of cognitive aging: executive decline and cognitive slowing. We tested the hypothesis that processing speed and executive function are differentially involved in timing depending on the temporal task used. We also tested the assumption of greater age-related effects in time estimation in old–old participants. Participants performed two standard temporal tasks: duration production and duration reproduction. They also completed tests measuring executive function and processing speed. Findings supported the view that executive function is the best mediator of reproduction performance and inversely that processing speed is the best mediator of production performance. They also showed that young–old participants provide relatively accurate temporal judgments compared to old–old participants. These findings are discussed in terms of compensation mechanisms in aging.
