摘　　要：采用GNAT范式并结合事件相关电位(ERP),考查不同矛盾状态(高矛盾VS低矛盾)被试对特殊群体的态度及其在行为、脑加工机制上的差异。结果表明:(1)个体对于乙肝患者存在矛盾态度;(2)高、低矛盾被试对乙肝患者的态度差异,主要表现在积极维度而非消极维度上。(3)N270的出现及LPC的差异表明,矛盾态度的加工是个体根据背景对预存性评价予以修正的过程。Combining with GNAT paradigm and ERP, the different attitudes of subjects with were explored different ambivalence degree （high ambivalence VS. low ambivalence） toward special groups, and their differences in behavior and brain mechanism. The results show： （1） different attitudinal ambivalence toward hepatitis B patients is individual concurrent positive and negative evaluation to one object. （2） The different attitudes of subjects with different ambivalence degree mainly represent in positive dimension, but not in negative dimension. （3） The evidences of N270 appearance and LPC difference suggest individual correcting one＇s stored evaluation according to that processing attitudinal ambivalence is the process of context.
