不同模糊程度下模糊决策的决策偏好

The Decision-making Preference under Different Ambiguity Conditions

该研究采用艾尔斯伯格悖论的变式,选取二择一的迫选任务,旨在探讨不同球数和不同模糊程度下模糊决策的决策偏好。结果发现,球数的不同对决策的偏好基本上没有影响;而模糊程度的不同,对决策的偏好有影响。具体表现为:模糊程度较高时,被试倾向于模糊厌恶,模糊程度较低时倾向于模糊寻求。

The decision preference under different ambiguity conditions was researched using the modification of Ellsberg paradox with a choice between two alternatives.The results suggested that the number of the balls in the bottle had no difference to the decision preference.But there was a significant difference to the decision preference under different ambiguity conditions.When the degree of the ambiguity was higher,the participants demonstrated ambiguity aversion.When the degree of the ambiguity was lower,the participants demonstrated risk seeking.
