To do so, College of Architecture and Urbanism of Shahid Beheshti University, the School of Architecture and Urbanism of University of Science and Technology and College of Fine Arts of University of Tehran were selected for case study and then, using analytical hierarchy process, seven common items between them were scored. In this analysis, six indicators associated with behavior and space were selected by the researcher and scored by two groups of experts and students. Using the map of behavioral patterns, the conformity of the mentioned groups' opinions with the model obtained from gatherings in space was obtained by the researcher. Accordingly, the results from the College of Fine Arts and the opinions of the mentioned groups were consistent. However, there was a slight difference in the ranking of spaces at Shahid Beheshti University. And, at the University of Science and Technology, the difference was found greater compared to the other two. According to the research information, it was concluded that the sense of place and the aesthetic concepts were essential indicators in synomorphy, and physical and cognitive elements can be effective in improvement and manner of behavioral patterns and use of space by people.
