Abstract

In case an learner is sought to see graphically displayed data on computer displays and to make various judgments,it is very important to understand how different display formats affect cognitive judgment of the displayed data. For a clearer understanding of the cognitive effects of computer display formats on human judgment, this study made learners estimate the numerosity of dot data on a computer display in some conditions by means of magnitude estimation, and compared the differences of the results in age gap between adults and elementary school students. The results are as follows. (1)For all the display conditions, the number of dots was more underestimated as the dots increased. (2) When the dots were scattered in relatively large area with a surrounding frame, the dot numerosity was the least underestimated. (3)These results were estimated more extremely in elementary school students.
