特质共情对道德判断的影响:来自ERP的证据

The Influence of Trait Empathy on Moral Judgment:An ERP Study Evidence

目的:探讨特质共情对道德判断的影响及其神经机制。方法:先根据44名被试在人际反应指数量表的得分将其分为高、低特质共情组,然后采用事件相关电位技术考察两组被试完成道德判断任务时的行为和脑电指标。结果:行为结果显示,高特质共情组对不道德行为的责备程度大于低特质共情组。脑电结果显示,道德行为比不道德行为诱发了更大的N1、N2波幅和更小的LPP波幅;高特质共情组道德行为的N1波幅大于不道德行为,低特质共情组则无此差异。结论:高特质共情个体对道德刺激更敏感,在道德判断过程中具有道德直觉加工优势。

Objective:To explore the neural mechanisms underlying the impact of trait empathy on moral judgment.Methods:Firstly,44 participants were divided into high and low trait empathy groups based on their Interpersonal Reactivity Index scores.Then,all participants completed the moral judgment task during which their behavioral and neural responses were recorded.Results:Behavioral results showed that individuals in high trait empathy group assigned more blame to immoral behaviors comparing to individuals in low trait empathy group.EEG results showed that moral behaviors induced greater N1 and N2 amplitudes,but smaller LPP amplitudes,than immoral behaviors did.Moreover,for individuals in high trait empathy group,moral behaviors elicited significantly more negative N1 than immoral behaviors did,whereas there was no such dfference for individuals in low trait empathy group.Conclusion:Individuals in high trait empathy group are more sensitive to moral content and have a moral intuition processing advantage during moral judgment.
