Annotation	Studies on the effects of ageing on estimating short time intervals are not conclusive. This Spanish research evaluated age-related differences in the reproduction of a short interval (10 seconds) using a computerised method, with 13 young adults (mean age 26.15) and 12 older people (mean age 79.1). Three parameters of time estimation were measured: absolute time, estimated error, and standard deviation. Results showed that time estimates performed by older participants were shorter than those of younger ones, although there were no significant differences between the two age groups in the percentage of absolute errors or standard deviations. Findings could be explained by changes in the rate of the internal clock, or to an interaction between more general changes in cognitive processes. (RH).
