Historically, evidence of self-recognition in development has been associated with the "rouge test"; however, this has been often criticized for providing a reductionist picture of self-conscious behavior. With two event-related potential (ERP) experiments, this study investigated the origin of self-recognition. Six- to eight-month-old infants (42 males and 35 females, predominately White, tested in the UK in 2022-2023) were presented with images of their face, another peer's face, and their mother's face (N = 38, Exp.1), and images of their own face morphed into another peer's face (N = 39, Exp.2). Results showed an enhanced P100 in infants' ERP response to their own face compared to others' faces (Exp.1 only), suggesting the presence of an enhanced attentional mechanism to one own's face as early as 6 months.
从历史上看，发展中的自我认知证据与“胭脂测试”有关；然而，这种方法经常受到批评，因为它提供了一种对自我意识行为的简化描述。本研究通过两项事件相关电位（ERP）实验，探讨了自我认知的起源。2022-2023 年在英国进行的研究中，对 6 至 8 个月大的婴儿（42 名男性和 35 名女性，主要为白人）展示了他们自己的脸、另一个同龄婴儿的脸和他们母亲的脸的图像（N=38，实验 1），以及他们自己的脸与另一个同龄婴儿的脸融合的图像（N=39，实验 2）。结果表明，与他人的脸相比，婴儿的 ERP 对自己的脸的反应中 P100 增强（仅实验 1），这表明早在 6 个月大时，婴儿就已经对自己的脸产生了增强的注意力机制。
