Since the theoretical formalisation of the concept of place-identity (Proshansky, Fabian & Kaminoff, 1983) a new tradition has begun to evolve from the perspective of environmental psychology, which seeks to relate socio-physical aspects of the environment to processes and theories of identity. In the light of the existing literature, it seems valid to claim that this tradition has become gradually consolidated since then (Feldman, 1990; Giuliani, 1991; Hormuth, 1990; Hunter, 1987; Korpela, 1989, 1996; Krupat, 1983; Lalli, 1988, 1992; Proshansky & Fabian, 1987; Sarbin, 1983; Twigger & Uzzell, 1996; Uzzell, 1995; Valera, 1993, 1996, 1997; Valera & Pol, 1994). In summary, the aim is to bridge a conceptual gap highlighted by Proshansky, Fabian & Kaminoff: the fact that aspects related to the physical environment are largely neglected in psycho-social theories, and in particular in the theories of social identity.
