Abstract
Spatial expansion of congnitive territory, each dweller is occupying during his urban daily life, has been composed in relation both with his life-activities and physical environment. It is different in each other, and will be changed when he come in another circumstance, and get to understand the sturucture of it. On the other hand, it, I think, well refects an order of human-scale in a field where he live in a every time. Summing up these of dwellers living in the same district, through a measuring method, I get a cognitive sphere-map which is tend to expand area over it's own district, and overlapping each other in the urban area. Urban spatial composition, of which effective on planning, can be clalified with these cognitive sphere-maps. I aim to demonstrate these theories mainly on analysis of questionnaires, distributed among dwellers in the D.I.D (Density Inhabited District) of the three medium-scaled cities-Yonezawa (Yamagata pref), Kamaishi (Iwate pref) and Hoya (Tokyo), which are different in physical structures, histories, citizen's behaiviors and productive-affairs.
