This paper reviews some partial findings of on empirical study relating to the differential perceptions laymen and professionals have of each other. Such differences are accounted for by reference to professional norms associated with clinical and/or community organizational practice. The impact of these lay/professional differences on the voluntary association in which they are mutually implicated is discussed together with the organizational place and position afforded professionals in different communities.
