伴隨決策而來的後悔：行動造成的後悔程度差異

Abstract

本研究改良獨裁者實驗來進行後悔理論的驗證，將60位受試者分成三組：看似偏低、看似偏高與隨機分配，利用實驗操弄影響受試者對於對手的觀感，藉由結果與受試者事先預期的落差來操弄後悔的出現。利用重複量數的統計方法比較前後差異，歸納出後悔所造成的行為改變幅度。 結果顯示看似偏高的分配造成的後悔高於看似偏低的分配，後悔情緒與行為改變的幅度不一定成正比。

This paper comes from detector game to prove regret theory. We separate all 60 attendants into 3 groups：looks-like-unfavorable, looks-like-favorable, and random. We use the experiment to affect the attendants’ perception of their opponents, and create the feeling of regret by creating gaps between their expectation and real outcomes. Then we use statistics to prepare the results, and induce the degree of reaction change based on different degree of regret. The result shows that looks-like-favorable situation will cause higher degree of regret, and the feeling of regret is not absolutely related to the degree of reaction change.
