Kupritz (2000a), for the most part, reorganizes and extends Altman’s privacy regulation theory. She expands Altman’s analysis of privacy regulation mechanisms, for example, by adding physical environmental mechanisms including barriers such as walls and positions of physical elements. Also, Kupritz reorganizes the theory by differentiating social from cultural mechanisms and by expanding psychological mechanisms to include cognitive ones. In addition, she specifies the
means that mechanisms employ and she specifies relationships among variables in a more specific way than Altman did. Kupritz’s addition of physical environmental elements and her research on architectural aspects of privacy (Kupritz, 2000b) are consistent with Altman’s (1975) emphasis on environmental mechanisms (cf. Altman, 1990) and with the popular view that Atman’s theory is an “environmental” theory of privacy.
