本文报道了三种图示形式的问题表征对符合期望效用理论的复合选择约简原则的影响的实证研究。最常见的表示形式，书面问题陈述，与三种图形表示进行了比较：包含100个标记球的管子、每列大小与相应事件的概率成比例的决策矩阵和条形图。管表示法导致对该原则的违反较少。此外，当受试者被训练从书面问题陈述构建比例矩阵时，他们比那些接受相同问题格式的受试者表现出更少的违规行为。这里报道的结果应该有助于发展一种人们框定决策问题的方式的理论。
This paper reports an empirical investigation of the effects of three pictorial forms of problem representation on conformance with the Reduction of Compound Alternatives Principle of expected utility theory. The most common form of representation, written problem statements, was compared with three pictorial representations: tubes containing one hundred labeled balls, decision matrices with each column proportional in size to the probability of the corresponding event, and bar graphs. The tubes representation led to fewer violations of the Principle. In addition, when subjects were trained to construct proportional matrices from written problem statements, they exhibited fewer violations than those who received the same problems already formatted in proportional matrices. The results reported here should contribute to the development of a theory of the way people frame decision problems.
