• A pictorial timeline method was developed for event time estimation.
• We compared event time estimation across older and younger age group.
• Older adults projected a smaller time window compared to younger adults.
• The possible confounding variable, i.e., spatial bias, was ruled out.
• Older adults' underestimation of time could be due to deficits in attentional controls.
How do older adults compare with younger adults in estimating the timing of daily events, such as heating a meal, keeping an appointment, or taking medication? In Experiment 1, we used a pictorial timeline method to examine age-related changes in how people estimate the time involved in daily events. We also conducted a spatial processing task to control for possible age-related bias in spatial processing. Findings showed that older adults projected smaller windows of time on the timeline to represent the duration of events than did younger adults, which indicates that older adults underestimate time duration. However, older adults also projected smaller windows in spatial task, which creates ambiguity in interpreting the reduced duration estimates among older adults. In Experiment 2, we administered an improved timeline task and spatial task that were comparable in difficulty between age groups and used defined endpoints of the reference line. Consistent with findings from Experiment 1, older adults projected a smaller time window than their younger counterparts, whereas the two age groups showed no differences in estimating spatial distances in the improved spatial experiment. Taken together, our findings suggest that older adults make shorter estimates of the duration of an event than younger adults, and that these age differences are due to age-related differences in orientation to time rather than to a general bias in spatial processing.
