Whether development of autism impacts the interactive process between an infant and his/her parents remains an unexplored issue.
Using computational analysis taking into account synchronic behaviors and emotional prosody (parentese), we assessed the course of infants' responses to parents' type of speech in home movies from typically developing (TD) infants and infants who will subsequently develop autism aged less than 18 months. Our findings indicate: that parentese was significantly associated with infant responses to parental vocalizations involving orientation towards other people and with infant receptive behaviours; that parents of infants developing autism displayed more intense solicitations that were rich in parentese; that fathers of infants developing autism spoke to their infants more than fathers of TD infants; and that fathers' vocalizations were significantly associated with intersubjective responses and active behaviours in infants who subsequently developed autism.
The parents of infants who will later develop autism change their interactive pattern of behaviour by both increasing parentese and father's involvement in interacting with infants; both are significantly associated with infant's social responses. We stress the possible therapeutic implications of these findings and its implication for Dean Falk's theory regarding pre-linguistic evolution in early hominins.
自闭症的发展是否会影响婴儿及其父母之间的互动过程，这仍然是一个尚未探索的问题。
我们使用计算分析方法，考虑到同步行为和情感韵律（父母语），评估了来自正常发育（TD）婴儿和随后发展为自闭症的婴儿的家庭电影中婴儿对父母言语类型的反应过程，这些婴儿的年龄均小于 18 个月。我们的研究结果表明：父母语与婴儿对涉及对他人的定向的父母发声的反应以及婴儿的接受行为显著相关；患有自闭症的婴儿的父母表现出更强烈的请求，这些请求富含父母语；患有自闭症的婴儿的父亲比 TD 婴儿的父亲更多地与婴儿交谈；并且父亲的发声与随后发展为自闭症的婴儿的主体间反应和主动行为显著相关。
随后发展为自闭症的婴儿的父母通过增加父母语和父亲参与与婴儿互动来改变他们的互动行为模式；这两者都与婴儿的社交反应显著相关。我们强调了这些发现的可能治疗意义及其对 Dean Falk 关于早期人类前语言进化理论的影响。
