| 摘 要： | 采用事件相关电位技术探讨人脑的内侧额叶负波在最后通牒任务中是否受不同情绪状态的影响并且其差异是否与责任感这一人格特质有关.结果发现,相对于负性情绪及公平情境,MFN的波幅在正性情绪和不公平情境中显著较大;相对于正性情绪和公平情境,在负性情绪和不公平情境中责任感人格维度得分越高,MFN波幅越正.结果表明,MFN反映的是对决策情境的认知评价且正性情绪更有利于对决策情境的觉知;责任感通过削弱由不利情境带来的认知反应来压制个体对于决策情境的敏感性,以追求更好的决策结果.这为MFN在真实的社会互动任务中表现出来的差异提供了具有较高生态学效度的神经电理学证据.

| Abstract: | The event-related potential technique was used to explore whether the medial frontal negativity (MFN) was impacted by conscientiousness in different emotional states. We found that compared to negative emotions and fair offers,larger MFN amplitudes were found in positive emotions and unfair offers; in negative emotions and unfair offers,conscientiousness and the amplitude of MFN had a positive relationship,related to positive emotions and fair offers. The results reveal that the MFN reflected the cognitive ... |
