This review article discusses and critically analyses three theories used to
explain how architecture and the natural and built-physical environment influence a
person's identity. These theories are (1) place-identity theory, (2) social identity theory,
and (3) identity process theory. The place-identity theory has provided important
contributions to the field of psychology and to the social sciences of architecture,
emphasizing the influence of the physical environment on identity and self-perception.
However, there is little empirical research to support the theory and its specific
contributions in relation to other identity theories have not been clarified. Despite the lack
of awareness in mainstream psychology regarding the built environment, the processes
described in social identity theory and identity process theory have been shown to be
useful when explaining the relationship between identity and place. Nevertheless, as
terminology, "place-identity" may be relevant, if seen as a part of other identity
categories. Identity manifests itself on many levels, one of which is place. A new
integrative model of place in built and natural environments is proposed.
