道德决策的机制及干预研究:自我相关性与风险水平的作用

现有的道德决策脑机制研究更多地关注了认知和情绪的交互作用,较少关注个体对"自我相关性"和"风险水平"信息的整合加工,更是忽视了帮助情境和伤害情境下道德决策的心理与脑机制的异同。因此,有必要通过行为、事件相关电位(ERP)和多模态脑功能成像(f MRI)等多种方法来系统考察帮助和伤害情境下自我相关性和风险水平交互影响道德决策的认知和神经机制,并进一步探讨共情训练对道德决策的干预作用。旨在揭示道德决策的时间进程和神经基础;探寻自我相关性与风险水平对道德决策的影响,及其在不同情境和共情水平下可能存在的变异;共情训练能否有效提升个体的道德决策水平。

Study on the mechanism and intervention of moral decision: Effects of self-relevance and risk level

In current studies on the brain mechanism of moral decision,more attention has been given to the interaction between cognition and emotion with very little focus on the individual's integrated processing about the self-relevance and risk level information,which ignores the difference and similarity of psychological and brain mechanism from moral decision in both harming and helping situation.Hence,this study adopts behavioral experiments,event related potential technology and multi modality brain functional imaging technology to explore the inter-influence between self-relevance and risk level and its effects on moral decision's cognitive and neural mechanism in both situations,with a further discussion on the empathy training's intervention on moral decision.The purpose of this study is to investigate the temporal course and neural substrate of moral decision,and to elaborate the influence of self-relevance and risk level on moral decision and its possible variations in different situations and empathy levels;at same time,this study also evaluates empathy training's effects on the enhancement of individual's moral decision.
