信息外部表征形式对个体决策框架效应的影响研究

The Effects of External Information Representation on Framing Effect in Individual Decision-Making

决策者容易被决策方案的框架所干扰,面对效用相同的方案因其框架不同而做出不同选择,而这些选择有时会产生负面影响,降低决策绩效。文章以框架效应为研究对象,探讨信息外部表征形式转换成图形的过程中可能带来的影响,研究将信息外部表征形式(文字、图形)与框架效应类型(风险、属性、目标)构建成2×3被试间实验,以153名大学生作为被试,分别对文字和图形表征形式下的决策框架进行选择,研究发现,图形表征组在风险和属性框架类型下的决策行为没有受到框架效应的影响:

Decision makers might be disturbed by the framing of decision scheme and make a different choice of different frame when faced with programs of same utility, however, the chosen choices sometimes may have a negative impact and thus fails to achieve a satis-factory decision-making performance. This thesis studies the framing effect, explores whether the form of external representation of infor-mation in the process of converting the picture will have impact on the decision scheme. The study characterizes the forms of external infor-mation （ text, graphics） and the framing effect types （ risk, property, target） to construct the experimental subjects, and choose 153 col-lege students as testers to detect their choices. The results show that framing effects have no impact on decision-making behavior of the representations of graph presentation under the framework of risk and property.
