ABSTRACT
Social decision-making research studies the mutual influences exerted by group members upon each other. To investigate this social decision schemes were postulated, which implicitly or explicitly transform the differing opinions of individuals into group decisions (Davis, 1973, 1982; Isenberg, 1986; Kaplan & Miller, 1983). For a brief review of the history of that research see also the contribution of Davis in this volume. The research on social decision schemes, if it considers the process of social judgment, includes process characteristics as a part of the scheme. The schemes, however, usually are not conceptualized to describe or to predict the process itself.
