Faces transmit rich information about a unique personal identity. Recent studies examined how negative evaluative information affects event-related potentials (ERPs), the relevance of individual differences, such as trait anxiety, neuroticism, or agreeableness, for these effects is unclear. In this preregistered study, participants (N = 80) were presented with neutral faces, either associated with highly negative or neutral biographical information. Faces were shown under three different task conditions that varied the attentional focus on face-unrelated features, perceptual face information, or emotional information. Results showed a task-independent increase of the N170 component for faces associated with negative information, while interactions occurred for the Early Posterior Negativity (EPN) and the Late Positive Potential (LPP), showing ERP differences only when paying attention to the evaluative information. Trait anxiety and neuroticism did not influence ERP differences. Low agreeableness increased EPN differences during perceptual distraction. Thus, we observed that low agreeableness leads to early increased processing of potentially hostile faces, although participants were required to attend to a face-unrelated feature.

人脸传递有关独特个人身份的丰富信息。最近的研究检查了负面评价信息如何影响事件相关电位 (ERP)，个体差异的相关性，如特质焦虑、神经质或宜人性，对这些影响的相关性尚不清楚。在这项预先注册的研究中，参与者（N= 80) 呈现中性面孔，要么与高度负面的或中性的传记信息相关联。在三种不同的任务条件下显示面部，这些任务条件不同，注意力集中在与面部无关的特征、感知面部信息或情感信息上。结果显示，与负面信息相关的面孔的 N170 成分与任务无关地增加，而早期后消极 (EPN) 和晚期积极电位 (LPP) 发生相互作用，仅在注意评估信息时才显示出 ERP 差异。特质焦虑和神经质不影响 ERP 差异。低宜人性增加了感知分心期间的 EPN 差异。因此，我们观察到低宜人性导致对潜在敌对面孔的早期处理增加，
