  • Abstract: Logically equivalent but different descriptions (i.e., manipulation of verbal expressions) affect decision-making in a phenomenon known as the framing effect. A choice architecture changes decision-makers’ actions, which in turn create different frames, but little is known about whether the frame created by their action can change their judgments. We examined whether self-initiated action induced by a choice architecture changed evaluations. In two experimental studies (N = 271), we found that self-initiated actions whose final goal was completely the same and for which no verbal expressions were manipulated led to different evaluations. In particular, we found that a difference in the placement of rewards, which required participants to behave differently, changed their ratings of satisfaction with the rewards. This study provides evidence that the framing effect can occur without verbal manipulation. This finding advances our understanding of how participants’ actions lead to different evaluations.

  • 日本語によるコメント（オプション，200-300字で）：意思決定を行う場合，情報の意味する内容が同じであっても，その問題認識の心理（決定フレーム）によって異なる結果が導かれることをフレーミング効果(framing effect)と呼びます。これまで，意思決定者の自発的な行為(self-initiated action)によって形作られた決定フレームが意思決定の対象に対して異なる評価や判断を導くことは報告されていませんでしたが，本研究では，教示や報酬を操作することなしに，このことを実験的に示しました。本研究の成果は，フレーミング効果の定義に再考を迫るものだと考えています。
