Sex has a significant impact on the perception of emotional expressions. However, it remains unclear whether sex influences the perception of emotions in artificial faces, which are becoming popular in emotion research. We used an emotion recognition task with FaceGen faces portraying six basic emotions aiming to investigate the effect of sex and emotion on behavioural and electrophysiological parameters. 71 participants performed the task while EEG was recorded. The recognition of sadness was the poorest, however, females recognized sadness better than males. ERP results indicated that fear, disgust, and anger evoked higher amplitudes of late positive potential over the left parietal region compared to neutral expression. Females demonstrated higher values of global field power as compared to males. The interaction between sex and emotion on ERPs was not significant. The results of our study may be valuable for future therapies and research, as it emphasizes possibly distinct processing of emotions and potential sex differences in the recognition of emotional expressions in FaceGen faces.
性别对情绪表达的感知有重要影响。然而，目前尚不清楚性别是否会影响人工面孔的情绪感知，因为人工面孔在情感研究中越来越受欢迎。我们使用了带有六种基本表情的 FaceGen 面孔的情绪识别任务，旨在调查性别和情绪对行为和电生理参数的影响。71 名参与者在记录 EEG 的同时完成了任务。结果表明，悲伤的识别效果最差，但女性的识别能力优于男性。ERP 结果表明，与中性表情相比，恐惧、厌恶和愤怒在左顶叶区域引发了更高的晚正电位振幅。与男性相比，女性的全局场强值更高。性别和情绪对 ERP 的相互作用不显著。我们的研究结果对于未来的治疗和研究可能具有重要价值，因为它强调了在 FaceGen 面孔中，情绪的处理可能存在性别差异，以及对情绪表达的识别可能存在性别差异。
