Three sessions were held: T1, T2, and T3. In Session T1, 192 1st to 6th graders observed two cars running on two parallel tracks on CRT displays and judged which car had run the longer duration. In Session T2, children observed them and judged which of the two cars had started first and which car had stopped first, then observed the same movements and again judged which car had run for the longer duration. In Session T3, children observed three times the same movement: they first judged the distance, then the speed, and finally the duration. The main results were as follows:(a) In younger children, judging correctly the same starting or stopping points as being the same was considerably difficult.(b) In older children, even if they could judge correctly the starting and stopping points, some of them did not use that information to judge the duration.(c) It seemed that for many children it was easier to use information on distance and speed than to use information concerning temporal starting and stopping points in order to judge the duration.
