自他の相対化が討議の生産性に及ぼす効果

抄録

This study examined the effects of relativization of the self and others with conflicting opinions on dyadic discussion productivity in face-to-face and computer-mediated situations. Two conditions were set, depending on the level of agreement in the discussion, and two more conditions pertaining to the recognition of similarity of the partner’s general attitude. The messages in the discussion were evaluated from the perspectives of diversity of issues, advantages of the opponent opinion, and politeness of expression. Experiment 1 (N = 78) involved a computer-mediated situation, in which agreement was strongly required, and results indicated productive effects of diversity of points of view while comparing the self with others. Moreover, while recognizing that the self and the partner were similar, polite expression increased as a result of relativization. However, in Experiment 2 (N = 66) in a face-to-face situation, the effect of suppressing productivity was observed symmetrically. Changes in the continuity of the dialogue, differences in the effects of relativization between situations, and applicability of relativization were discussed.
