摘　　要：目的:以效率与公平相关决策研究为例,探讨人脑电位对行为反应的预测.方法:本研究采用E-Prime程序和事件相关脑电位技术记录了22名健康被试完成效率与公平权衡决策实验时的行为数据和脑电数据,并进行分析.结果:被试对效率的行为敏感性(个体对高效率与低效率的行为反应的差异)可由他们先前对效率的脑电敏感性(个体对高效率与低效率的脑电反应的差异)预测;被试对公平的行为敏感性(个体对高公平与低公平的行为反应的差异)可由他们先前对公平的脑电敏感性(个体对高公平与低公平的脑电反应的差异)预测.结论:本研究例示了个体脑电差异可以预测个体行为差异.Objective:To investigate whether human brain potentials can predict human behavioral responses in the decision situations involving efficiency and fairness.Methods:This study used E-Prime and event-related brain potential technique to collect behavioral and brain-potential data from 22 subjects when they made decisions involving trade-off between efficiency and fairness,and analyzed these data using EEGLAB and SPSS.Results:Behavioral sensitivity to efficiency(subjects'behavioral responses to high efficiency minus subjects'behavioral responses to low efficiency)can be predicted by their previous brain-potential sensitivity to efficiency(subjects'brain-potential responses to high efficiency minus their brain-potential responses to low efficiency).Similarly,behavioral sensitivity to fairness(subjects'behavioral responses to high fairness minus subjects'behavioral responses to low fairness)can be predicted by their previous brain-potential sensitivity to fairness(subjects'brain-potential responses to high fairness minus their brain-potential responses to low fairness).Conclusion:This research exemplify individual differences in behaviors can be predicted by individual differences in brain potentials.
