Previous studies showed that, from birth, speech and eye gaze are two important cues in guiding early face processing and social cognition. These studies tested the role of each cue independently; however, infants normally perceive speech and eye gaze together. Using a familiarization-test procedure, we first familiarized newborn infants (n = 24) with videos of unfamiliar talking faces with either direct gaze or averted gaze. Newborns were then tested with photographs of the previously seen face and of a new one. The newborns looked longer at the face that previously talked to them, but only in the direct gaze condition. These results highlight the importance of both speech and eye gaze as socio-communicative cues by which infants identify others. They suggest that gaze and infant-directed speech, experienced together, are powerful cues for the development of early social skills.
先前的研究表明,从出生起,言语和眼神注视就是引导早期面部处理和社会认知的两个重要线索。这些研究分别测试了每个线索的作用;然而,婴儿通常会一起感知言语和眼神注视。通过使用熟悉-测试程序,我们首先让 24 名新生儿观看带有直接注视或回避注视的陌生说话面孔的视频。然后,用之前看到的面孔和一个新面孔的照片对新生儿进行测试。新生儿会更长时间地注视之前与他们说话的面孔,但只在直接注视的情况下。这些结果突出了言语和眼神注视作为社会交际线索的重要性,婴儿可以通过这些线索来识别他人。它们表明,一起体验到的注视和针对婴儿的言语是发展早期社交技能的有力线索。
