Parental language input influences child language outcomes but may vary based on certain characteristics. This research examined how parental language differs during two contexts for toddlers at varying likelihood of autism based on their developmental skills. Parental language (quantity, quality, and pragmatic functions) was analyzed during dyadic play and mealtime interactions as a secondary data analysis of observational data from a study of toddlers at elevated and lower likelihood of autism. Child developmental skills and sensory processing were also assessed. Parents used more words per minute, directives, and verbs during play and more adjectives, descriptions, and questions during mealtime. Parental language differed based on child fine motor skills, receptive language, and levels of sensory hyporesponsiveness but not autism likelihood. Overall, this study found that parental language varies based on context and child developmental skills. Future research examining parental language should include pragmatic functions and context across developmental trajectories.

父母的语言输入会影响孩子的语言结果，但可能会根据某些特征而有所不同。这项研究根据幼儿的发展技能，考察了在两种环境下，对于患有不同自闭症可能性的幼儿，父母的语言有何不同。在二元游戏和进餐互动期间对父母语言（数量、质量和语用功能）进行了分析，作为对自闭症可能性升高和降低的幼儿研究中观察数据的二次数据分析。还评估了儿童发展技能和感觉处理。父母在玩耍时每分钟使用更多的单词、指令和动词，在进餐时使用更多的形容词、描述和问题。父母的语言因孩子的精细运动技能、接受性语言和感觉反应低下的水平而有所不同，但与自闭症的可能性无关。总的来说，这项研究发现，父母的语言会根据环境和孩子的发展技能而有所不同。未来研究父母语言的研究应包括跨发展轨迹的语用功能和背景。
