大脑单侧化对公平判断框架效应的影响

The Influence of Brain Lateralization on Framing Effect in Fairness Judgment

目的:探讨大脑单侧化对公平判断框架效应的影响。方法:采用经典决策范式和单耳听力任务探讨被试在得失框架和大脑单侧化激活条件下的公平判断情况。结果:实验1发现被试在未得框架下的公平判断显著高于损失框架下的公平判断。实验2发现大脑单侧化激活对公平判断框架效应具有调节作用,左脑激活的被试公平判断受框架效应影响不显著;右脑激活的被试公平判断受到框架效应的显著影响,即被试在未得框架下的公平判断显著高于损失框架下的公平判断。结论:与未得框架相比,损失框架让个体产生更低的公平感;公平判断框架效应仅出现在右侧脑被激活的被试中。

Objective:To explore the effect of brain lateralization on the framework of fair judgment.Methods:The classical decision paradigm and the monocular hearing task were used to explore the fair judgment of the subjects under the conditions of the gain and loss framework and the unilateral activation of the brain.Results:Experiment 1 found that the participants1 fair judgment on urestoring the original price"was significantly higher than the fair judgment on"rising the price".Experiment 2 found that unilateral activation of the brain had a regulatory effect on the framework of fair judgment.The fair judgment of the subjects with left brain activation was not significantly affected by the framework effect;The fair judgment of the right brain activation subject was significantly affected by the framework effect,that is to say,the fair judgment of the subject on the"restoring the original price"was significantly higher than the fair judgment of"rising the price".Conclusion:"Rising the price"will give the individual a lower fair judgment than"restoring the original price";The framework effect of fairness judgment only occurs in subjects whose right brain is activated.
