An experiment was done in one area with grid shaped street pattern and in another area with irregularly twisted street pattern. There were two ways to memorize forms in the experiment: a real walk and CG animation presented walk through a fixed pathway. After learning the course, the subject walked the pathway by themselves. Originally the subjects were 25 males and 15 females. The results were analysed based on gender difference-14 male and 14 female subjects. Analysing errors in the abstract distance and abstract angle errors on the cognitive maps, it was recognized that the drawn street lengths are shorter than the actual distances for both genders. Concerning a real walk through the irregularly twisted street the females' errors in the abstract angles were smaller than the males' errors. However both gender's found the irregularly twisted street more legible than the grid shaped one.
