导致明确的镜子自我识别的婴儿依赖于两个关键的信息来源：当看到镜子中反映的一个人的动作时，感觉运动和多感觉信号的持续整合，以及与自我相关的独特面部特征。虽然视觉外观和多感官偶发线索可能是实现自我识别的两个可能的候选过程，但它们各自的贡献仍然知之甚少。在这项研究中，18个月大的婴儿看到了自己和同龄人的并排照片，这些照片是系统地同时用手触摸面部的。在观看刺激的同时，婴儿自己的脸被同步或不同步地触摸，并测量了他们的优先观看行为。随后，婴儿接受了镜片测试任务。我们证明，在镜子测试中被编码为非识别者的婴儿比看另一张脸的照片花的时间要多得多，无论多感官输入是同步的还是异步的。我们的结果表明，就在镜像自我识别开始之前，与多感官线索相比，关于自我的特征信息在识别面孔的过程中可能更相关。
Leading up to explicit mirror self‐recognition, infants rely on two crucial sources of information: the continuous integration of sensorimotor and multisensory signals, as when seeing one's movements reflected in the mirror, and the unique facial features associated with the self. While visual appearance and multisensory contingent cues may be two likely candidates of the processes that enable self‐recognition, their respective contribution remains poorly understood. In this study, 18‐month‐old infants saw side‐by‐side pictures of themselves and a peer, which were systematically and simultaneously touched on the face with a hand. While watching the stimuli, the infant's own face was touched either in synchrony or out of synchrony and their preferential looking behavior was measured. Subsequently, the infants underwent the mirror‐test task. We demonstrated that infants who were coded as nonrecognizers at the mirror test spent significantly more time looking at the picture of their own face compared to the other‐face, irrespective of whether the multisensory input was synchronous or asynchronous. Our results suggest that right before the onset of mirror self‐recognition, featural information about the self might be more relevant in the process of recognizing one's face, compared to multisensory cues.
