| Abstract: | An extension of the T. M. Ostrom and H. S. Upshaw perspective model (1968, in A. Greenwald, T. Brock, and T. Ostrom (Eds.), Psychological foundations of attitudes, New York: Academic Press) of attitudinal judgments, incorporating a subjective scale range concept, was examined in relation to the effects of group interaction on individual members' attitudinal judgments. Subjects made attitudinal judgments after reading a criminal case history and then, either individually or as members of four person groups, decided on the appropriate sentence for the criminal for two different cases. The results showed that the subjective scale range concept was useful to account for the subjects' attitudinal judgments. Further analysis showed that the group interaction provided both informational and normative influences on the individual members' judgments in different ways. These findings are discussed in terms of judgmental processes postulated by Ostrom and Upshaw. |
