当每个 6 个月大的孩子观看母亲脸部和陌生人脸部的照片时，记录了事件相关电位（ERP）。两张脸的 ERP 不同，但引发的神经活动模式取决于母亲和陌生人看起来不同（实验 1，n = 22）还是相似（实验 3，n = 22）。相比之下，当向不同的 6 个月大的孩子分别展示这 44 对面孔中的 1 张时，他们的 ERP 在 2 张面孔之间没有差异（实验 2，n = 22，实验 4，n = 22）。在视觉识别偏好测试中，婴儿没有表现出识别母亲脸部的证据（实验 5，n = 32）。总之，这些结果表明婴儿能够识别母亲的面孔，但（1）伴随识别的神经过程取决于区分母亲和陌生人的难度；（2）在本研究调查的条件下，ERP 是比注视时间更敏感的识别测量。
Event-related potentials (ERPs) were recorded from 6-month-olds as each watched pictures of the mother's face and a stranger's face. The ERPs differed for the 2 faces, but the pattern of neural activity elicited depended on whether the mother and stranger looked different (Experiment 1, n = 22) or alike (Experiment 3, n = 22). In contrast, when different 6-month-olds were each shown 1 of these 44 pairs of faces their ERPs did not differ between the 2 faces (Experiment 2, n = 22, and Experiment 4, n = 22). In a visual preference test of recognition, infants showed no evidence of recognizing the mother's face (Experiment 5, n = 32). Together, these results suggest that infants are able to recognize their mothers' faces but (1) the neural processes accompanying recognition depend on the difficulty with which mother can be discriminated from stranger and (2) under the conditions investigated in this study, ERPs are a more sensitive measure of recognition than is looking time.
