本研究旨在探讨听觉言语信息对12个月大婴儿注视无声说话面孔行为的影响。我们研究了德国婴儿在对两种语言中的一种进行听觉熟悉之前和之后，对双语者的脸进行扫描的行为。双语者的脸在一边默念德语，在另一边默念法语。结果显示，12个月大的婴儿对这两种视觉演讲都没有普遍的视觉偏好，在听觉输入之前和之后都没有。但是，与没有听觉语言输入的扫描行为相比，听到母语的婴儿减少了对嘴巴区域的注视时间，并将更多的注意力集中在眼睛上，而听到非母语的婴儿则增加了对嘴巴区域的视觉注意，减少了对眼睛的关注。因此，我们可以假设，12个月大的婴儿比那些听过非母语语言的婴儿更快地识别出他们的母语，并将他们的视觉注意力更多地引导到眼睛区域。
The present eye-tracking study aimed to investigate the impact of auditory speech information on 12-month-olds' gaze behavior to silently-talking faces. We examined German infants' face-scanning behavior to side-by-side presentation of a bilingual speaker's face silently speaking German utterances on one side and French on the other side, before and after auditory familiarization with one of the two languages. The results showed that 12-month-old infants showed no general visual preference for either of the visual speeches, neither before nor after auditory input. But, infants who heard native speech decreased their looking time to the mouth area and focused longer on the eyes compared to their scanning behavior without auditory language input, whereas infants who heard non-native speech increased their visual attention on the mouth region and focused less on the eyes. Thus, it can be assumed that 12-month-olds quickly identified their native language based on auditory speech and guided their visual attention more to the eye region than infants who have listened to non-native speech.
