作为社会分类基础的早期感知过程可以通过事件相关脑电位（ERPs）来检测。使用这种方法，本工作旨在检测基于性别类别的内群体和外群体成员的注意加工差异。具体而言，三项脑电图研究考察了增强社会身份相关性的因素，即性别认同和性别表征的情境显著性，如何调节神经性别分类效应。研究1表明，女性（研究1a）和男性（研究1b）都更有可能表现出对内部群体成员的优先关注，而不是外部群体成员，但只有当他们强烈认同自己的性别群体时才会如此。研究2表明，当跨群体领导背景下的性别类别变得突出时（即，与男性相比，女性在数字上的代表性不足，而不是平等的代表性），无论性别认同水平如何，女性都表现出对群体内成员的优先关注，而不是群体外成员。本研究为以下两方面提供了经验证据：(1)男性和女性在面部知觉后100 ms内的神经性别分类效应；(2)增强社会认同相关性的因素在早期性别分类中的调节作用。
The very early perceptional processes that underlie social categorization can be detected with event-related brain potentials (ERPs). Using this methodology, the present work aims to detect differential attentional processing of ingroup and outgroup members based on gender categories. Specifically, three EEG studies tested how factors that enhance social identity relevance, namely gender identification and contextual salience of gender representation, moderate neural gender categorization effects. Study 1 showed that both women (Study 1a) and men (Study 1b) were more likely to show preferential attention to ingroup over outgroup members, but only when they identified strongly with their gender group. Study 2 showed that when gender categories in an intergroup leadership context were made salient (i.e., when women were numerically underrepresented versus equally represented compared to men), women, irrespective of their level of gender identification, showed preferential attention to ingroup over outgroup members. Together, this work provides empirical evidence for (1) the neural gender categorization effect among both men and women as soon as 100 ms after face perception and (2) the moderating role of factors that enhance social identity relevance in early gender categorization.
