研究人员记录了6个月大的婴儿在观看母亲和陌生人面部照片时的事件相关电位（ERPs）。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是不同（实验1，n = 22）还是相似（实验3，n = 22）。相比之下，当不同的6个月大的婴儿分别看到这44对面孔中的1对时，他们的erp在这两对面孔之间没有差异（实验2，n = 22，和实验4，n = 22）。在识别的视觉偏好测试中，婴儿没有表现出识别母亲面孔的证据（实验5，n = 32）。总之，这些结果表明，婴儿能够识别母亲的脸，但(1)伴随识别的神经过程取决于母亲与陌生人区分的困难程度；(2)在本研究调查的条件下，erp是一个比注视时间更敏感的识别指标。
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.
