【摘要】：已有研究显示，决策选项能够通过属性的变化影响后悔的程度。本研究旨在考察选项规模对后悔的影响的原因，并且通过两种模拟情景（愿意与不愿意）验证研究结论，提高生态效度。研究一依据决策情景分为两个实验情景（愿意/不愿意），以149名大学生为被试，，分别采用2（规模：2选项/3选项）×2（多样性：相似/不相似）的被试间设计，探讨了两种决策情景下选项规模和多样性对后悔的影响。结果显示，两种情景下，选项规模均对后悔无显著影响，多样性均对后悔显著影响，且规模和多样性的交互效应显著。即后悔程度均随多样性的增加而增加，增加不相似的选项显著增加后悔的程度。研究二同样依据决策情景分为两个实验情景（愿意/不愿意），以86名大学生为被试，分别采用2（规模：2选项/3选项）×2（评价维度：2维度/3维度）的混合设计，其中规模采用被试间设计，评价维度采用被试内设计，探讨两种决策情景下选项规模和评价维度对后悔的影响。结果显示，两种情景下，选项规模均对后悔无显著影响，评价维度均对后悔显著影响。即增加选项的评价维度，后悔程度随之增加。基于以上实验结果，可以认为单纯增加选项的数量，不能显著改变后悔的程度。对于同类选项或不同类选项，选项多样性对后悔的影响主要通过评价维度的变化产生，即选项多样性增减，评价维度相应增减，后悔程度随之增减。
[Abstract]:Previous studies have shown that decision options can influence the degree of regret through changes in attributes. This study was designed to examine the reasons for the effects of the scale of options on regret, and to verify the findings of the study through two simulation scenarios (willing and unwilling). Improve ecological validity. The first study was divided into two experimental scenarios (willing / unwilling) according to decision scenarios. 149 college students were chosen as subjects, and the subjects were designed with 2 (scale: 2 / 3) 脳 2 (diversity: similarity / dissimilarity), respectively. The effects of scale and diversity of options on regret in two decision scenarios were discussed. The results showed that the scale of options had no significant effect on regret in both scenarios, but diversity had significant effects on regret. The interaction between scale and diversity is significant, that is, the degree of regret increases with the increase of diversity, and the degree of regret increases with the increase of dissimilar options. Study 2 was also divided into two experimental scenarios (willing / unwilling) according to decision-making scenarios. 86 college students were chosen as subjects, using a mixed design of 2 (2 / 3 of scale option) 脳 2 (evaluating dimension 2: 2 dimension / 3 dimension), respectively. The scale was designed among the subjects and the evaluation dimension was designed within the subjects. The effects of the scale of options and the dimension of evaluation on regret under two decision scenarios were discussed. The results showed that the scale of options had no significant effect on regret in both scenarios. The evaluation dimension has significant influence on regret, that is, the degree of regret increases with the increase of the evaluation dimension of options. Based on the above results, it can be concluded that simply increasing the number of options can not significantly change the degree of regret. That is, the diversity of options increases or decreases, the evaluation dimension increases or decreases, and the regret degree increases and decreases.
