Abstract

Studies of contextual choice typically use three option choice sets to evaluate how preference relations depend on the values of a third decoy option. However, often real-world decisions are made using choice sets with many more than three alternatives, such as in online shopping. Three experiments tested for attraction and compromise decoy effects in choice sets that varied the number and ordering of alternatives using a within-subjects preferential choice grocery shopping task. In Experiment 1, attraction and compromise effects were significantly reduced as alternatives increased from three to nine. Experiment 2 found significantly greater attraction effects in nine alternative choice sets ordered by attributes compared with a random ordering. Experiment 3 used eye tracking and found significant attraction effects in choice sets with 3, 9, and 15 alternatives, but the effect was reduced with increasing alternatives. Eye tracking revealed that participants engaged in more by-dimension comparisons as the number of alternatives increased, but, contrary to previous research, the proportion of by-alternative to by-dimension transitions was not linearly predictive of decoy effects. With increased alternatives, the proportion of the total information attended to decreased, leading to worse choice outcomes, and participants were more likely to engage in a lexicographic decision-making strategy.

选择集复杂性对诱饵效应的影响
对情境选择的研究通常使用三个选项的选择集来评估偏好关系如何取决于第三个诱饵选项的值。然而,现实世界中的决策往往是使用多于三个备选方案的选择集做出的,例如在网上购物中。有三项实验利用主体内优先选择杂货店购物任务,测试了选择集中不同数量和排序的备选方案的吸引和折中诱饵效应。在实验 1 中,当备选方案从 3 个增加到 9 个时,吸引和妥协效应明显减弱。实验 2 发现,与随机排序相比,按属性排序的九套备选方案的吸引效应明显更大。实验 3 使用了眼动追踪,发现在有 3、9 和 15 个备选方案的选择集中,吸引力效应非常明显,但随着备选方案的增加,这种效应有所减弱。眼动追踪显示,随着备选方案数量的增加,参与者参与了更多的分维度比较,但与之前的研究相反,从备选方案到分维度的转换比例并不能线性地预测诱饵效应。随着备选方案的增加,所关注的全部信息的比例会下降,从而导致更差的选择结果,而且参与者更有可能采用词典决策策略。

期刊介绍: The Journal of Behavioral Decision Making is a multidisciplinary journal with a broad base of content and style. It publishes original empirical reports, critical review papers, theoretical analyses and methodological contributions. The Journal also features book, software and decision aiding technique reviews, abstracts of important articles published elsewhere and teaching suggestions. The objective of the Journal is to present and stimulate behavioral research on decision making and to provide a forum for the evaluation of complementary, contrasting and conflicting perspectives. These perspectives include psychology, management science, sociology, political science and economics. Studies of behavioral decision making in naturalistic and applied settings are encouraged.
