Environmental Psychology deals with the relation between people and their physical and social settings. It gives a prominent place to environmental perceptions, attitudes, evaluations and representations and accompanying behaviour, in order to address the logic of these interrelations in terms of interaction or transaction. Notions of space and place occupy a central position in environmental psychology. Classically the spatial dimension leads to address the relation to the environment referring to the people and communities within, at different levels from the private space level to the level of global environment: (1) Private Spaces (individual level): personal and private space, dwelling, housing, workplace, office; (2) Public/Private Environments (neighbourhood-community level): semi-public spaces, blocks of flats, the neighbourhood, parks, green spaces; (3) Public Environments (individual / community level, inhabitants) : involving both built spaces (villages, towns, cities) as well as the natural environment (the countryside, landscape, etc.), and (4) The Global Environment (societal level) : the environment in its totality, both the built and the natural environment, natural resources. At each of theses four levels cultural and temporal dimensions intervene in different manners, and environmental psychology is challenged by specific pluridisciplinary approaches.
