Replication: Beyond gains and losses by Mishra and Fiddick (2012)
摘要
The standard framing effect demonstrates a deviation from expected utility theory (and rational choice theory) that is consistent with prospect theory. Findings by Mishra and Fiddick (2012) suggest that such framing effects may be better explained in terms of a sensitivity to minimal acceptable thresholds, or needs, as described in risk-sensitivity theory. To evaluate the reliability of the findings reported by Mishra and Fiddick (2012), we conducted a close preregistered replication of their Experiment 3 with a larger, well-powered sample ( N = 399) of UK students recruited via Prolific. Our results partly replicated the original findings: In line with the original study, we observed the standard framing effect and that individuals with higher need more often selected the risky option. Results for the crucial hypothesis were mixed: In the original study, the framing effect disappeared when the analysis stratified by need. In the replication, when we stratified by need, we observed a framing effect among participants with low need, but not among participants with high need. These findings contribute to the understanding of both prospect theory and risk-sensitivity theory in explaining the standard framing effect.
中文摘要
标准框架效应表明，个体决策会偏离期望效用理论（及理性选择理论），这一偏离与前景理论相一致。Mishra和Fiddick（2012）的研究发现提示，此类框架效应或许可以更好地用对最低可接受阈值或需求的敏感性来解释，如风险敏感性理论所述。为评估Mishra和Fiddick（2012）所报告发现的可靠性，我们对其实验3进行了严格的预注册重复研究，样本量更大且统计效力充分（N = 399），为通过Prolific招募的英国学生。我们的结果部分重复了原始发现：与原始研究一致，我们观察到了标准框架效应，并且需求较高的个体更常选择风险选项。关键假设的结果则好坏参半：在原始研究中，按需求分层分析时框架效应消失。在重复研究中，当我们按需求分层时，我们在低需求参与者中观察到了框架效应，但在高需求参与者中未观察到。这些发现有助于理解前景理论和风险敏感性理论在解释标准框架效应方面的作用。
