Paying attention to time as one gets older.

Published

Journal Article

Age-related changes in attention and interval timing as a function of time of day were examined using a temporal bisection task with single and compound auditory and visual stimuli. Half of the participants in each age group were tested in the morning, and half were tested in the afternoon. Duration judgments were found to be shorter for visual signals than for auditory signals. This discrepancy was greater in the morning than in the afternoon and larger for the older than for the younger adults. Young adults showed equal sensitivity to signal duration for single and compound trials and higher sensitivity in the afternoon than in the morning for both signal modalities. In contrast, older adults showed impaired sensitivity on compound trials and the greatest sensitivity overall to single visual trials in the morning. These results suggest that age-related reductions in attentional resources may cause older adults to focus on signals that require controlled attention during specific phases of the circadian cycle.
