中文摘要：

近年来有研究指出,情感会影响认知决策。为探究在认知决策中情感冲突的作用和脑内信息加工的神经机制,本研究应用统计参数图方法,分析了道德两难问题ERP的时空特征。根据道德违背的程度,实验材料分为涉及个人的高道德冲突情景和非涉及个人的低冲突情境。结果表明,随着道德判断的进行,差异性的电活动从双侧颞枕区向前额中区延续,高道德违背情境会更强地抑制额区和额中央区等的电活动。结果支持了道德两难问题是感性判断和理性判断双重加工的理论,并且证明理性判断的做出是通过情境认知和对情感处理抑制达到的。

英文摘要：

Based on the statistical parametric mapping（SPM）,this study analyzed the spatiotemporal pattern of electroencephalogram（EEG） data to investigate the information processing mechanisms of moral judgment.This experiment divided the hypothetical scenarios into two sets by the conflict of moral dilemmas： the ＂personal＂scenarios（higher conflict） and the＂non personal＂scenarios（lower conflict）.The aberrant EEG expanded from bilateral temporal to the ventromedial prefrontal cortex（VMPC） as the process of moral judgment.The higher conflict of moral dilemmas restrained the EEG in the prefrontal and VMPC.These findings provide support to the hypothesis that moral judgment is a complex process involved emotional and utilitarian judgments,and suggest the decision of moral judgments relied on the utilitarian judgment and emotional restraint.
