Although emerging evidence suggests that parental behavior is related to the development of child executive functioning (EF), the mechanisms through which parenting affects child EF have yet to be investigated. The goal of this study was to examine the potential mediating role of child language in the prospective relation between maternal autonomy support and child EF. A total of 53 mother-infant dyads took part in three home visits at 15months, 2years, and 3years, allowing for the assessment of maternal autonomy support (T1), child expressive vocabulary (T2), and child EF (T3). The results suggested that child language played a mediating role in the relation between maternal autonomy support and child performance on EF tasks entailing a strong impulse control component above and beyond child previous EF and family socioeconomic status (SES). In contrast, no such mediating role of language was found with EF tasks tapping mostly into working memory and set shifting. Thus, this study highlights one pathway through which parenting can affect child executive control.
虽然新出现的证据表明，父母的行为与儿童执行功能（EF）的发展有关，但父母教养方式影响儿童 EF 的机制仍有待研究。本研究的目的是检验儿童语言在母亲自主支持与儿童 EF 之间的前瞻性关系中的潜在中介作用。共有 53 对母婴参与了三次家访，分别在 15 个月、2 岁和 3 岁，以评估母亲自主支持（T1）、儿童表达词汇（T2）和儿童 EF（T3）。结果表明，儿童语言在母亲自主支持与儿童执行功能任务表现之间的关系中起着中介作用，这种关系超出了儿童之前的执行功能和家庭社会经济地位（SES），涉及到强烈的冲动控制成分。相比之下，在涉及到工作记忆和定势转移的执行功能任务中，语言并没有起到中介作用。因此，本研究强调了教养方式影响儿童执行控制的一种途径。
