Numerous discoveries regarding stereotypes have been uncovered by utilizing techniques and methods developed by cognitive psychologists. The present study continues this tradition by borrowing psychophysiological techniques used for the study of memory and language, and applying them to the study of stereotypes. In this study, participants were primed with either the gender category 'Women' or 'Men', followed by a word which was either consistent with gender stereotypes (e.g. Women: Nurturing) or inconsistent (e.g. Women: Aggressive). Their task was to indicate whether the words matched or did not match, according to gender stereotypes. Both response times and event-related brain potentials (ERPs) were recorded during performance of the task. As predicted, stereotype incongruent word pairs were associated with larger N400 ERP amplitudes and slower response times, relative to congruent word pairs. The potential utility of this approach as an independent measure of stereotypes is discussed.
通过运用认知心理学家开发的技术和方法，人们发现了许多关于刻板印象的内容。本研究延续了这一传统，借鉴了用于记忆和语言研究的心理生理学技术，并将其应用于刻板印象研究。在本研究中，参与者被启动了“女性”或“男性”的性别类别，随后呈现一个与性别刻板印象相符（如女性：有养育性）或不符（如女性：有攻击性）的词语。他们的任务是根据性别刻板印象指出这些词语是否匹配。在任务执行过程中记录了反应时间和事件相关脑电位（ERP）。正如预期的那样，与相符的词语对相比，刻板印象不一致的词语对与更大的N400 ERP波幅和更慢的反应时间相关。讨论了这种方法作为刻板印象独立测量手段的潜在效用。
