Starting with a reflection on the disciplinary, theoretical, methodological and terminological multiplicity, and using the analogy of the multivariate model of the canonical correlation, the use of the label Person-Environment Studies is justified. This is followed by a discussion of four spatial concepts (personal space, territoriality, crowding and privacy) and their relationship to mobility. After some comments about affordance, it is suggested that the mobility-affordance link constitutes the molecular element of the reciprocal person-physical space relationship at the core of the Person-Environment Studies.
