[Sex and age differences in the subjective assessment of time by preschoolers].

Time perception was studied in children under school age from 2.5 to 6 years. Using cross-modal matching, the children assessed durations of 1-, 3-, 5-, 7-, and 10-sec sound signals. It was found out that children under school age, irrespective of sex, more accurately estimated the extreme durations in the internal range (1 and 10 sec). In contrast to girls, boys reveal a clear-cut tendency to minimize the variability of assessments with age. Nevertheless, this tendency is not related with the attention level.
