Abstract

The predominant use of temporal information in everyday life concerns behaviour within the psychological present, which is said to have an upper limit of approximately 3-5 s. The present study was designed to investigate agedifferences in processing of temporal information within the psychologicalpresent by applying three distinct psychophysical tasks with base durations of I s. Forty young (mean age: 21.6 years) and forty older adults (mean age: 70.4 years) were presented with a temporal discrimination task, a temporal reproduction task, and a repeated production task, Pronounced impairment in older adults, as compared to young adults, was found for temporal discriminations. When asked to reproduce a 1-s target interval, young adults under-reproduced and older adults over-reproduced the target duration, but did not differ in overall accuracy and intra-individual variability. Repeatedproductions of a 1-s interval were unaffected by age. These findings are consistent with the notion that older adults show impaired performance when stimulus timing is required, whereas response timing is unaffected by ageing.
