本研究采用事件相关电位（ERPs）技术，探讨了情绪人格对面孔加工的影响。在学习阶段，参与者观看目标个体的面部（表情中性或微弱的微笑），并与描述目标先前典型行为的消极，中性或积极句子配对。在接下来的EEG测试阶段，参与者完成了学习面孔的性别判断。对性别判断任务期间的神经活动进行了统计分析。重复测量的ERP数据的方差分析表明，被描述为具有负面人格的面孔引起更大的N170比那些中立或积极的描述。早期后验负波（EPN）显示了相同的结果模式，与消极人格配对的面孔比其他面孔具有更大的幅度。与积极人格配对的面孔的晚期正电位的大小大于与中性和消极人格配对的面孔。目前的研究表明，情感人格信息与自动的，自上而下的面孔加工调制。
This study explored the extent to which there are the neural correlates of the affective personality influence on face processing using event-related potentials (ERPs). In the learning phase, participants viewed a target individual’s face (expression neutral or faint smile) paired with either negative, neutral or positive sentences describing previous typical behavior of the target. In the following EEG testing phase, participants completed gender judgments of the learned faces. Statistical analyses were conducted on measures of neural activity during the gender judgment task. Repeated measures ANOVA of ERP data showed that faces described as having a negative personality elicited larger N170 than did those with a neutral or positive description. The early posterior negativity (EPN) showed the same result pattern, with larger amplitudes for faces paired with negative personality than for others. The size of the late positive potential was larger for faces paired with positive personality than for those with neutral and negative personality. The current study indicates that affective personality information is associated with an automatic, top–down modulation on face processing.
