这项研究调查了患有自闭症谱系障碍遗传风险(高风险)的婴儿与没有这种风险(低风险)的婴儿相比，母亲对婴儿交流的反应。总共观察了26名婴儿，其中12名有患有自闭症谱系障碍的哥哥姐姐，在13个月和18个月大的时候，他们与母亲进行了自然主义的家庭互动和半结构游戏。结果表明，总体而言，低风险和高风险婴儿的母亲对婴儿的交流行为反应高度相似。然而，对婴儿的语音和手势交流发展以及母亲的言语反应和翻译(即在口头上标记手势参照物)的检查表明，在高危婴儿的早期交流发展中观察到的延迟可能会改变这些婴儿接受的输入；这反过来可能会对随后的交流和语言的发展产生连锁影响。
This study investigates mothers’ responses to infant communication among infants at heightened genetic risk (high risk) of autism spectrum disorder compared to infants with no such risk (low risk). A total of 26 infants, 12 of whom had an older sibling with autism spectrum disorder, were observed during naturalistic in-home interaction and semistructured play with their mothers at 13 and 18 months of age. Results indicate that overall, mothers of low-risk and high-risk infants were highly and similarly responsive to their infants’ communicative behaviors. However, examination of infant vocal and gestural communication development together with maternal verbal responses and translations (i.e. verbally labeling a gesture referent) suggests that delays in early communication development observed among high-risk infants may alter the input that these infants receive; this in turn may have cascading effects on the subsequent development of communication and language.
