Abstract
Differences in duration judgments made by younger and older adults
were reviewed. Previous research is unclear about whether such differences
exist and, if so, how they may be explained. The meta-analyses revealed
substantial age-related differences. Older adults gave larger verbal
estimates and made shorter productions of duration than did younger
adults. There were no age-related differences in reproduction of
duration or in psychophysical slope relating judged and target duration.
Older adults' duration estimates were more variable than were those
of younger ones. Findings are discussed in terms of pacemaker rate
and attentional resources. An explanation regarding divided attention
between nontemporal and temporal information processing best explains
the findings.
