Data Sheet 1_The effect of moral identity on facial emotion processing in adolescents with hearing loss: an event-related potentials study.docx

ObjectiveThis study investigates how the moral characters of others influence the recognition of facial emotional expressions in adolescents with hearing loss (HL), and compares these effects with those in adolescents with typical hearing (TH).
MethodsA moral priming paradigm was employed to explore the neural mechanisms underlying facial emotion perception (happy, neutral, and angry) in different moral contexts (high moral, low moral). Event-related potentials (ERP) were utilized to assess brain responses.
ResultsAdolescents with TH evaluated emotional valence independently of moral context. In contrast, adolescents with HL judged faces with low moral levels more negatively. ERP analyses showed facial expression processing in adolescents with TH was not influenced by moral information, whereas adolescents with HL exhibited moral effects during both the middle (N2) and late stages (LPP) of processing.
ConclusionThese findings underscore distinct neurocognitive mechanisms of emotion recognition in adolescents with HL and highlight the significant influence of moral identity on their emotional judgments.

本研究旨在探讨他人的道德特质如何影响听力损失（hearing loss, HL）青少年的面部情绪表情识别，并将该效应与典型听力（typical hearing, TH）青少年进行对比。
方法：本研究采用道德启动范式，探究不同道德情境（高道德、低道德）下面部情绪感知（快乐、中性、愤怒）的神经机制，并利用事件相关电位（Event-related potentials, ERP）技术评估大脑反应。
结果：典型听力青少年对情绪效价的评估不受道德情境的影响。与之相对，听力损失青少年对低道德特质面孔的评价更为负面。事件相关电位分析结果显示，典型听力青少年的面部表情加工并未受道德信息的调控，而听力损失青少年则在加工的中期（N2）与晚期（LPP）阶段均表现出道德效应。
结论：本研究结果揭示了听力损失青少年与典型听力青少年在情绪识别方面存在差异化的神经认知机制，并凸显了道德特质对听力损失青少年情绪判断的显著影响。
