Previous researches revealed low judged quality of decision process increased regret. We hypothesized people with high perfectionism judged the quality was low even if they had enough information, therefore, they anticipate more regret during decision making. In the experiment of this study, the participants performed the lottery task. The amount of information for decision making was different among trials. In every trial, the participants rated the quality of decision making after choice. As the result, the judged quality increased depending on the amount of information but the degree of increase was smaller in high-perfectionists. This result supported our hypothesis. Furthermore, the judged quality of decision process negatively predicted the reaction time of choice. According to previous researches, people take more time when they anticipate regret. The result suggests perfectionists anticipate more regret. The relation between perfectionism and regret is possible to clarify the mechanism about maladaptive cognition in perfectionists.
