Human risk-taking attitudes can be influenced by two logically equivalent but descriptively different frames, termed the framing effect. The classic hypothetical vignette-based task (Asian disease problem) and a recently developed reward-based gambling task have been widely used to assess individual differences in the framing effect. Previous studies treat framing bias as a stable trait that has genetic basis. However, these two paradigms differ in terms of task domain (loss vs. gain) and task context (vignette-based vs. reward-based) and the convergent validity of these measurements remains unknown. Here, we developed a vignette-based task and a gambling task in both gain and loss domains and tested correlations of the framing effect among these tasks in 159 young adults. Our results revealed no significant correlation between the vignette-based task in the loss domain and the gambling task in the gain domain, indicating low convergent validity. The current findings raise the question of how to measure the framing effect precisely, especially in individual difference studies using large samples and expensive neuroscience methods. Our results suggest that the framing effect is influenced by both task domain and task context and future research should be cautious about the operationalization of the framing effect.
人类的冒险态度可能会受到两种逻辑上等效但描述上不同的框架的影响,这被称为框架效应。经典的基于假设小场景的任务(亚洲疾病问题)和最近开发的基于奖励的赌博任务已被广泛用于评估框架效应中的个体差异。先前的研究将框架偏差视为一种具有遗传基础的稳定特质。然而,这两种范式在任务领域(损失与收益)和任务背景(基于小场景与基于奖励)方面存在差异,并且这些测量方法的收敛效度仍然未知。在这里,我们开发了一个基于小场景的任务和一个在收益和损失领域的赌博任务,并测试了159名年轻人在这些任务中框架效应的相关性。我们的结果显示,损失领域中基于小场景的任务与收益领域中的赌博任务之间没有显著相关性,这表明收敛效度较低。当前的研究结果提出了如何精确测量框架效应的问题,特别是在使用大样本和昂贵神经科学方法的个体差异研究中。我们的结果表明,框架效应受到任务领域和任务背景的影响,未来的研究在框架效应的操作化方面应谨慎。
