A developmental study of temporal duration judgments.
First, third, fifth, and seventh graders and college students (18 per grade) made four serial reproductions of each of three time intervals, 8, 13, and 32 sec. The results paralleled those of other studies using only adults since both the psychophysical function and the Weber fraction were typical, and magnitude of judgments was an increasing, negatively accelerated function of trials. None of these effects was a function of age nor were there any age effects in an analysis of variable errors. Analysis of first-degree sequential dependency of judgments (using lag correlations) revealed a slight negative recency which was also invariant with age of Ss.
