An empirical research is presented dealing with the psychosocial study of the man-environment relationship through an analysis of cognitive representations. The cognitions that the inhabitants of the city of Rome have of different parts of this urban environment are studied: the residential quarter, the city center, the outskirts. The research has been carried;out in two different phases, the first explorative-intensivein nature and the second systematic-extensive. A categorical and multidimensional scheme of analysis has been hypothetically outlined in order to explain the variability between the different urban cognitive representations as far as their content and formal aspects are concerned.
