越来越多的基于成人神经影像学的证据表明，大脑会适应双语体验以支持语言熟练程度。青少年大脑认知发展（ABCD）研究是评估儿童时期这一说法的有用数据来源，因为它涉及大量美国儿童样本的数据。使用九岁和十岁收集的基线 ABCD 研究数据，本研究的目的是确定双语者和单语者之间皮质厚度的差异，并评估双语者英语词汇和英语使用的变异性如何解释这些群体差异。我们将双语参与者确定为讲非英语语言并在家中接触非英语语言的儿童。然后，我们根据年龄、性别、青春期状况、父母教育程度、家庭收入、非语言智商和惯用手，确定了英语单语参与者的匹配样本。在广泛的皮质区域中，双语者的皮质比单语者更薄。在双语者中，更多地使用英语与额叶和顶叶皮质厚度更大有关。更多的英语词汇量与更大的额叶和颞叶皮质厚度相关。这些发现重复并扩展了之前对双语儿童的研究，并强调了双语儿童和单语儿童之间无法解释的皮质厚度差异。
There is a growing body of evidence based on adult neuroimaging that suggests that the brain adapts to bilingual experiences to support language proficiency. The Adolescent Brain Cognitive Development (ABCD) Study is a useful source of data for evaluating this claim during childhood, as it involves data from a large sample of American children. Using the baseline ABCD Study data collected at ages nine and ten, the goal of this study was to identify differences in cortical thickness between bilinguals and monolinguals and to evaluate how variability in English vocabulary and English use within bilinguals might explain these group differences. We identified bilingual participants as children who spoke a non-English language and were exposed to the non-English language at home. We then identified a matched sample of English monolingual participants based on age, sex, pubertal status, parent education, household income, non-verbal IQ, and handedness. Bilinguals had thinner cortex than monolinguals in widespread cortical regions. Within bilinguals, more English use was associated with greater frontal and parietal cortical thickness; greater English vocabulary was associated with greater frontal and temporal cortical thickness. These findings replicate and extend previous research with bilingual children and highlight unexplained cortical thickness differences between bilinguals and monolinguals.
