选项框架和认知负载对风险决策的影响

本研究采用实验法探讨了选项框架和认知负载对风险决策的影响。结果发现:(1)不同的认知负载条件下,被试在正向框架下表现出风险回避,负向框架下表现出风险寻求,出现了框架效应现象;(2)相对于认知负载条件下,被试在无认知负载的负向框架下更偏好于风险选项,而正向框架下的风险偏好没有显著变化,即无认知负载条件下框架效应较强。这表明,框架效应不仅仅是启发式系统作用的结果,分析式系统也在其中发挥着重要的作用。

The Influence of Choice Framing and Cognitive Load on Risky decision

This study explored the influence of choice framing and cognitive load on risky decision by using experimental methods. The results showed that under different cognitive load conditions, subjects were of risk a- version with positive frames and risk seeking with negative frames, which is framing effects. Relative to high cognitive load conditions, subjects were more of risk aversion with negative frames under no load conditions, while subject＇ s risk preferences didn＇t significantly change with positive frames. Thus, it is suggested that framing effects may not simply result from heuristic processing, probably also from the analytic processing.
