When an operator(elementary school students) is required to view graphically displayed date on computer displays and to make various judgments,it is very important to understand how different display formats affect human judgment of the displayed date. As a step towards a clearer understanding of the effects of computer display formats on human judgment, the present study examined apparent dot numerosity on a computer display by means of magnitude estimation. 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 an relatively large area with a surrounding frame,the dot numerosity was the least underestimated. These results were discussed in terms of appropriate format of display.
