男性被认为在对儿童面部相似性的反应方面比女性有优势，这反映了男性在解决适应性父系不确定性问题和识别生物后代方面的进化压力。然而，以往的研究结果不一致，男性在儿童面部相似性知觉中的优势，作为一种亲属检测机制，仍然不清楚。本研究采用事件相关电位（ERP）技术，探讨了自我相似面孔加工的行为和脑机制，以及性别和年龄对自我相似面孔加工的影响。结果表明，男性在自相似儿童面孔的加工中具有稳定的优势，男性对自相似儿童面孔的检测率高于女性。对于ERP结果，男性表现出较小的N2和较大的晚正成分（LPC）振幅的自我相似的儿童面孔，这可能反映了面孔匹配和自我参照处理的亲属检测，分别。进一步的源性分析表明，N2成分和LPC分别来源于扣带回前部和额内侧回。我们的研究结果支持了男性在自我相似儿童检测中的优势，并进一步表明，这种区别可以在大脑不同区域的早期和晚期处理阶段中找到。
Males have been suggested to have advantages over females in reactions to child facial resemblance, which reflects the evolutionary pressure on males to solve the adaptive paternal uncertainty problem and to identify biological offspring. However, previous studies showed inconsistent results and the male advantage in child facial resemblance perception, as a kin detection mechanism, is still unclear. Here, we investigated the behavioral and brain mechanisms underlying the self-resembling faces processing and how it interacts with sex and age using event-related potential (ERP) technique. The results showed a stable male advantage in self-resembling child faces processing, such that males have higher detectability to self-resembling child faces than females. For ERP results, males showed smaller N2 and larger late positive component (LPC) amplitudes for self-resembling child faces, which may reflect face-matching and self-referential processing in kin detection, respectively. Further source analysis showed that the N2 component and LPC were originated from the anterior cingulate cortex and medial frontal gyrus, respectively. Our results support the male advantage in self-resembling child detection and further indicate that such distinctions can be found in both early and late processing stages in the brain at different regions.
