This event-related potential (ERP) study explored individual differences associated with gender and level of self-insight in early semantic processing. Forty-eight Chinese native speakers completed a semantic judgment task with three different categories of words: abstract neutral words (e.g., logic, effect), concrete neutral words (e.g., teapot, table), and emotion words (e.g., despair, guilt). They then assessed their levels of self-insight. Results showed that women engaged in greater processing than did men. Gender differences also manifested in the relationship between level of self-insight and word processing. For women, level of self-insight was associated with level of semantic activation for emotion words and abstract neutral words, but not for concrete neutral words. For men, level of self-insight was related to processing speed, particularly in response to abstract and concrete neutral words. These findings provide electrophysiological evidence for the effects of gender and self-insight on semantic processing and highlight the need to take into consideration subject variables in related research.
这项事件相关电位（ERP）研究探讨了早期语义加工中与性别及自我洞察水平相关的个体差异。四十八名以中文为母语的人完成了一项语义判断任务，任务包含三类不同的词汇：抽象中性词（如逻辑、效果）、具体中性词（如茶壶、桌子）和情感词（如绝望、内疚）。然后他们评估了自己的自我洞察水平。结果表明，女性比男性进行了更多的加工。性别差异也体现在自我洞察水平与词汇加工的关系上。对于女性来说，自我洞察水平与情感词和抽象中性词的语义激活水平相关，但与具体中性词无关。对于男性来说，自我洞察水平与加工速度有关，尤其是在对抽象和具体中性词的反应中。这些发现为性别和自我洞察对语义加工的影响提供了电生理证据，并强调在相关研究中需要考虑主体变量。
