【摘要】 采用事件相关电位(ERP)技术探讨了性别固定化人名及其代词(他或她)推测判断的脑内时程动态变化.结果发现:在350~500 ms内,"不一致"反应比"一致"反应诱发了一个更正的晚期ERP成分,在差异波(不一致-一致)中该正成分的峰值潜伏期约为400 ms左右(P400).差异波的地形图表明,P400主要在额顶部有明显的激活.偶极子溯源分析的结果显示,P400主要起源于扣带前回(ACC)(BA32/24)附近,可能反映了个体在性别刻板化人名与其不一致性别代词(她/他)发生冲突时的认知控制过程.另外还发现,不仅仅职业具有性别刻板化现象,在名字中也存在性别刻板化效应.更多还原

【Abstract】 The present study used Event-related brain potentials(ERPs) to investigate the neural mechanisms underlying names stereotypically associated with male and female and their pronouns(he and she).The subjects were asked to judge whether female or male names is consistent with their pronouns or not.Scalp ERP analysis revealed the neurophysiological substrate of the social cognitive processing of congruency.Incongruency elicited a more positive P400 than did congruency in the time window 350-500 ms.Dipole source analysis of the difference wave(Incongruency-congruency) indicated that a generator localized in the anterior cingulate cortex(ACC)(BA32/24) contributed to this effect,possibly related to conflict of social cognition and P400 may indicated failure of semantic or sexual information integration.This indicated it is more difficult to process the pronouns which violated the sex of antecedent names.Moreover,there was gender stereotype not only in occupations but also in given names.更多还原
