早年直视说话者的嘴巴预示着富有表现力的交流。我们假设，观察说话者的嘴巴可能表明婴儿已经准备好接受更多的支持联合参与，这随后促进了语言前声音的发展，并转化为在表达交流中更广泛的收获。我们在50名6-18个月大的婴儿中测试了这一假设，这些婴儿的自闭症诊断可能性和一般人群水平都很高(分别是SIBS-孤独症和SIBS-NA)。我们使用眼球跟踪任务测量婴儿对说话者面部的凝视，在亲子自由游戏会话期间支持联合参与，在交流样本中测量声音复杂性，以及更广泛的表达能力交流。看着嘴巴通过增加更高层次的支持关节参与和声音复杂性间接地与表现力交流有关。这种间接影响并不因兄弟姐妹地位的不同而异。这项研究为观察嘴巴可能影响表情交流发展的机制提供了初步的见解。在出生时，婴儿倾向于主要看着他们交流伙伴的眼睛。然而，在出生第一年的中途，婴儿开始越来越多地看着说话的人的嘴巴，以产生视听语言。这一发展变化与传播学在理论和研究上的发展都有着密切的联系。目前的研究提供了新的见解，准确地说，看嘴巴可能会影响患有自闭症和非自闭症儿童的婴儿兄弟姐妹的沟通发展。
Looking to the mouth of a talker early in life predicts expressive communication. We hypothesized that looking at a talker’s mouth may signal that infants are ready for increased supported joint engagement and that it subsequently facilitates prelinguistic vocal development and translates to broader gains in expressive communication. We tested this hypothesis in 50 infants aged 6–18 months with heightened and general population-level likelihood of autism diagnosis (Sibs-autism and Sibs-NA; respectively). We measured infants’ gaze to a speaker’s face using an eye tracking task, supported joint engagement during parent-child free play sessions, vocal complexity during a communication sample, and broader expressive communication. Looking at the mouth was indirectly associated with expressive communication via increased higher-order supported joint engagement and vocal complexity. This indirect effect did not vary according to sibling status. This study provides preliminary insights into the mechanisms by which looking at the mouth may influence expressive communication development. At birth, infants tend to look predominantly at the eyes of their communication partners. Midway through the first year of life, however, infants begin to look increasingly at the mouth of a talker producing audiovisual speech. This developmental change has been linked with the development of communication in both theory and research. The present study provides novel insights into precisely how looking at the mouth may scaffold communication development in infant siblings of children with and without autism.
