不同注意负荷对风险决策框架效应影响

The Impact of Different Attention Loads on the Risk Decision-Making Framework Effect

摘要: 目的：研究风险决策行为在框架(正性框架和负性框架)效应和集中注意与分散注意两种条件影响下的大脑加工机制。方法：采用Eprime收集在不同注意条件下不同决策框架任务中。结果：分析被试决策行为反应时和选择项比率发现：框架效应和注意力条件主效应显著，被试的决策行为在注意分散条件下的反应时显著高于在注意集中条件下的反应时；正性框架下更倾向于风险规避，在负性框架下更倾向于寻求冒险。结论：注意分散影响决策任务反应时间：在不同注意条件下，决策行为反应时差异显著。当在注意集中条件下时，被试进行决策行为更为迅速。决策信息框架会影响个体决策行为：正性框架下行为更倾向于保守；负性框架下行为更倾向于冒险。

Abstract: Objective: To study the brain processing mechanisms of risk decision-making behavior under the effects of frameworks (positive and negative frameworks) and the influence of two conditions: focused attention and dispersed attention. Method: Eprime was used to collect data from different decision-making framework tasks under different attention conditions. Result: Analysis of the reaction time and choice ratio of the decision-making behavior of the subjects revealed that the framing effect and attention condition main effect were significant, and the reaction time of the decision-making behavior of the subjects under attention dispersion conditions was significantly higher than that under attention concentration conditions; under a positive framework, there is a greater tendency towards risk aversion, while under a negative framework, there is a greater tendency to seek adventure. Conclusion: Attention dispersion affects decision task response time: under different attention conditions, there are significant differences in decision behavior response time. When under the condition of concentration of attention, participants make decisions more quickly. The decision-making information framework can affect individual decision-making behavior: under a positive framework, behavior tends to be more conservative; under a negative framework, behavior tends to be more adventurous.
