Factors Affecting Preferences over Ambiguity

PI建议研究模糊性在多属性决策中的作用。虽然大多数先前的研究都发现了决策中的模糊厌恶，但这一次PI发现了利用医疗决策情景寻求模糊。本研究将试图发现歧义寻求行为是否会推广到非医疗情况。在场景中将以各种方式创建歧义，场景的属性数量将不同，歧义的突出程度将不同，并且主体上的信息处理负荷将被操纵。此外，PI将调查现状的位置以及决策目标对受试者对模棱两可的反应的影响。

The PI proposes to investigate the role of ambiguity in multi-attribute decision making. Although most prior research has found ambiguity aversion in decision making, this PI has found ambiguity seeking using medical decision making scenarios. This research program will attempt to discover whether the ambiguity seeking behavior will generalize to non-medical situations. Ambiguity will be created in various ways in the scenarios, the scenarios will differ in their number of attributes, the salience of the ambiguity will be varied, and the information processing load on the subjects will be manipulated. In addition, the PI will investigate the location of the status quo and the influence of decision goals with regard to the subjects' reaction to ambiguity.
