在生命的第一年，参与持续同步互动的能力随着婴儿学会匹配社会伙伴的行为并随后调节自己的行为以回应他人而发展。在这些早期社会构建块中发展能力的困难会影响后期的语言技能，联合注意力和情绪调节。对于自闭症谱系障碍（ASD）风险升高的儿童，早期的二元同步和反应困难可能表明出现ASD和/或发育问题。作为前瞻性发展监测研究的一部分，ASD（高风险）和典型发育（低风险）儿童的婴儿兄弟姐妹，175名婴儿及其母亲（高风险组n = 104，低风险组n = 71）在婴儿6，9和12个月大时完成了标准化的游戏任务。这些相互作用的频率和持续时间的婴儿和母亲的目光，积极的影响，和发声，分别编码。使用这些代码，理论驱动的复合材料被创建为指数二元同步和婴儿/母亲的反应。多水平模型显示，在12个月大时，二进同步性和婴儿反应性存在显著的风险组差异。此外，无论哪一组，12个月时较高水平的同步性和反应性与36个月时的语言技能呈正相关。本研究的结果强调，促进二元同步和反应可能有助于促进自闭症风险升高的儿童的最佳发育。在抚养自闭症谱系障碍（ASD）儿童的家庭中，年幼的兄弟姐妹面临社会沟通困难的风险较高。本研究探讨了6个月、9个月和12个月大的亲子游戏任务中社交沟通差异是否明显。对于ASD儿童的婴儿兄弟姐妹，在12个月大时观察到游戏期间的社会差异，并可能为持续的监测和干预工作提供信息。
In the first year of life, the ability to engage in sustained synchronous interactions develops as infants learn to match social partner behaviors and sequentially regulate their behaviors in response to others. Difficulties developing competence in these early social building blocks can impact later language skills, joint attention, and emotion regulation. For children at elevated risk for autism spectrum disorder (ASD), early dyadic synchrony and responsiveness difficulties may be indicative of emerging ASD and/or developmental concerns. As part of a prospective developmental monitoring study, infant siblings of children with ASD (high-risk) and typical development (low-risk), 175 infants and their mothers (high-risk group n = 104, low-risk group n = 71) completed a standardized play task when infants were 6, 9, and 12 months of age. These interactions were coded for the frequency and duration of infant and mother gaze, positive affect, and vocalizations, respectively. Using these codes, theory-driven composites were created to index dyadic synchrony and infant/maternal responsiveness. Multilevel models revealed significant risk group differences in dyadic synchrony and infant responsiveness by 12 months of age. In addition, higher levels of synchrony and responsiveness at 12 months were positively associated with language skills at 36 months, regardless of group. The findings of the present study highlight that promoting dyadic synchrony and responsiveness may aid in advancing optimal development in children at elevated risk for autism. In families raising children with an autism spectrum disorder (ASD), younger siblings are at elevated risks for social communication difficulties. The present study explored whether social-communication differences were evident during a parent-child play task at 6, 9, and 12 months of age. For infant siblings of children with ASD, social differences during play were observed by 12 months of age and may inform ongoing monitoring and intervention efforts.
