摘要
期望理论运用S状的价值函数和非线性的权重函数来解释和预测框架效应。“齐当别”抉择模型将不同框架下的抉择行为简单地看成是“最好可能结果之间的取舍”或者“最坏可能结果之间的取舍”。本研究设计了一“匹配”技术,并用此对作者所报告过的支持框架效应与不支持框架效应的选择问题加以再检验。实验表明,采用不同的框架并不能预测性地决定不同的抉择偏爱,而匹配结果所示的“齐当别”策略则能更好地对所收集到的有关框架效应的数据作出解释。
An S-shaped value function and a nonlinear weighing function were employed by the prospect theory to explain and predict the framing effect. The choice behaviour under different frames was however simply seen by the equate-to-differentiate model as a choice between the best possible outcomes or a choice between the worst possible outcomes. A 'matching' task was designed to re-test some risky problems which had been demonstrated in the author's previous studies to support or to disprove the documented framing effect. It was shown in the present experiment that knowledge of the frame which was used did not permit prediction of option preference, and that the existing evidence in relation to the framing effect could be better accounted for by the equate-to-differentiate strategy (deciding which dimensional difference is to be equated and which is to be differentiated) revealed by the matching results.
