ABSTRACT Bilingual experience has an impact on an individual’s linguistic processing and general cognitive abilities. The relation between these linguistic and non-linguistic domains, in turn, is mediated by individual linguistic proficiency and developmental changes that take place across the lifespan. This study evaluated this relationship by assessing inhibition skills, and verbal fluency in monolingual and bilingual school-aged children (Experiment 1), young adults (Experiment 2), and older adults (Experiment 3). Results showed that bilinguals outperformed monolinguals in the measure of inhibition, but only in the children and older adult age groups. With regards to verbal fluency, bilingual children outperformed their monolingual peers in the letter verbal fluency task, but no group differences were observed for the young and old adults. These findings suggest that bilingual experience leads to significant advantages in linguistic and non-linguistic domains, but only at the time points when these skills undergo developmental changes.

在整个生命周期中整合双语、语言流畅性和执行功能

摘要 双语体验对个人的语言处理和一般认知能力有影响。反过来，这些语言和非语言领域之间的关系是由个人语言能力和整个生命周期发生的发展变化所介导的。本研究通过评估单语和双语学龄儿童（实验 1）、年轻人（实验 2）和老年人（实验 3）的抑制技能和语言流利程度来评估这种关系。结果表明，双语者在抑制方面的表现优于单语者，但仅限于儿童和老年人群。在语言流利度方面，双语儿童在字母语言流利度任务中的表现优于单语儿童，但在年轻人和老年人中没有观察到组别差异。
