One hundred and fifteen children of 2nd, 4th and 6th grades of primary school were asked to judge which of 2 graphic cars moving in parallel on CRT display was in a longer moving duration. Car pairs used, 36 in all, were typical exemplars representative of many combinations of 7 variables (cues): velocity, duration, distance, spatial (start, end) positions and temporal (start, end) positions. Assuming five types of children's answers according to cues used in their duration judgments, and comparing them with actually obtained answers, it was found that most of 2nd graders used spatial and temporal position cues in their judgment, while 6th graders judged mainly on the basis of real duration cue. In 4th graders, an intermediate state was recognized, and individual differences were much greater than others. The above mentioned findings were also confirmed with computer simulation analysis. Differences in results between present and previous studies were discussed, and problems for further investigations were pointed out.
