In this study, we explored the role of emerging inhibitory control skills in language acquisition in 62 typically developing children aged 24–32 months and investigated whether early inhibitory control skills are longitudinally associated with language outcome. Specifically, we focused on two different inhibitory processes that develop approximately at age 3, namely, response inhibition and interference suppression. At Time 1 children were administered five inhibitory control tasks and a language test; language abilities were also evaluated by means of a parent‐report questionnaire. Receptive morphosyntactic ability was assessed after 1 year (Time 2) in a subsample of 28 children. Hierarchical multiple linear regression analysis showed that all language production measures at Time 1, as well as later receptive morphosyntactic ability at Time 2, were significantly associated with the interference suppression score, even when early lexical and grammatical measures, age, and mother's education were included in the analysis.

幼儿和学龄前儿童的抑制控制技能和语言习得

在这项研究中，我们探讨了62名典型的24-32个月发育中儿童中新兴抑制控制技能在语言习得中的作用，并调查了早期抑制控制技能是否与语言结果纵向相关。具体而言，我们关注大约在3岁时出现的两种不同的抑制过程，即反应抑制和干扰抑制。在时间1，给孩子们执行五项抑制性控制任务和一项语言测验。语言能力也通过家长报告问卷进行了评估。1年（时间2）后，在28名儿童的子样本中评估了接受性吗啡句法能力。分层多元线性回归分析表明，在时间1时，所有语言的产生量度以及在时间2时，后期的语态句法接受能力
