数量を表現するポーズが属性フレーミング効果に及ぼす影響

The attribute framing effect is a phenomenon whereby logically equivalent but varied verbal expressions induce different decisions. Existing studies have primarily investigated the impact of differences in verbal expressions on the attribute framing effect; only a few have examined how it is affected by nonverbal information. In our real communication, verbal expressions are often accompanied by various nonverbal ones, such as gestures. Therefore, we investigated the effect of adding static poses that represent the quantity information included in the sentences that induce the attribute framing effect on decision-making bias. We also examined the extent of this effect. The results showed that the attribute framing effect induced a decision bias even when the poses were added. However, the impact of different pose types on the framing effect of attributes was not observed. Based on the results of this experiment, we discussed the effects of presenting people on decision-making, the differences in priority between verbal and nonverbal information, the influence of the intentions implied by poses, and the possibility of theoretical extensions to the attribute framing effect mechanism through comparison with previous research.
