Abstract
An experiment was done in one grid shaped street and one irregularly twisted street. There were two ways to memorize forms in the experiment : a real walk through the pathway or a CG animation presented walk through the same pathway.After memorizing the course, the subject walked the pathway by himself. The subjects were 40(25 males and 15 females). As a result of analyzing the distance and angle errors on thecongnitive maps, it was recognized that the written lengths, concerning both gender, are smaller than the actual distances. Concerning a real walk through the irregularly twisted street, females angle errors which reference line and the line which each corner connected the starting point make were smallest.
