摘　　要：决策框架效应作为一种违背不变性原则的非理性偏差,已经得到研究的广泛证实。本研究突破了传统研究中主要由语言描述引发框架效应的限制,从图形表征这一新的视角对图形框架效应做了深入探讨。本研究共包括6个实验,通过操纵选项在不同图形表征版本中物理属性差异的突出性,发现在表达信息不变的情况下,人们判断和决策的偏好会受到图形表征的影响,即出现了图形框架效应。研究结果表明,图形框架效应普遍存在于各种决策情境以及各种图形表征方式中。基于属性替代理论和齐当别原则,我们提出了一种解释图形框架效应内部作用机制的两阶段心理加工模型--图形编辑的齐当别模型(The Graph-edited Equate-to-differentiate Model,GEM)。In contrast to the axiom of description invariance, researchers interested in decision framing effects are accumulating evidence that different representations of the same problem do not yield the same preference. Traditional research on framing effects has commonly utilized verbal scenarios. In contrast, the current study manipulated the graphical representation of options by framing the physical characters in figures and found that preferences could be affected even when the words and numbers of the problem were constant. Our evidence showed that such graph framing effects could be detected across different types of graphical displays and different question scenarios. Based on attribute substitution theory and an equate-to-differentiate approach, we proposed a two-process model of graph framing effects： The Graphedited Equate-to-differentiate Model （GEM）.
