Happy Times are Longer When We are Older: Emotions Affect Time Perception in Older Adults

Emotions change people’s time perception, which has been evidenced in children and younger adults. However, older adults, who cognitively process positive stimuli to a greater extent than negative and neutral stimuli (Carstensen & Mikels, 2005), had been neglected in most empirical studies examining the role of emotion played in time perception. Using a temporal bisection task, the present study investigated age differences (Nolder =21, Nyounger=21) in time perception of negative (sad and angry), positive (happy), and neutral facial expressions. A significant age by emotion interaction in time perception was found in results, such that older adults perceived the presentation durations of happy faces longer than negative ones, whereas the opposite pattern was observed in younger adults. The present findings could be interpreted by the internal clock model and the “positivity effect” in older adults’ cognitive and affective processes.
