摘要

本研究的重点是美国研究不足但却最突出的双语人群--遗产双语者。本研究结合了八项核磁共振成像研究的数据，对 215 名传承的西班牙语-英语双语者和 145 名英语单语者的语言经验与皮层下灰质体积之间的关系进行了组内和组间研究。对于双语者来说，西班牙语（L1）水平越高，双侧球状苍白球的体积就越小，而英语（L2）水平越高、英语AoA越早，右侧丘脑、左侧延脑和双侧球状苍白球的体积就越大。对于单语学习者来说，较高的英语水平仅与右侧苍白球的体积增大有关。这些结果表明，皮层下灰质结构与第二语言的学习有关。我们鼓励未来的研究从发展的角度来理解皮层下适应与 L1 和 L2 学习的关系。

Subcortical volume and language proficiency in bilinguals and monolinguals: A structural MRI study

The current study focused on an understudied but most prominent bilingual population in the U.S. – heritage bilinguals. The current study combined data from eight MRI studies to examine the relationship between language experience and subcortical gray matter volume in 215 heritage Spanish-English bilinguals and 145 English monolinguals, within and between groups. For bilinguals, higher Spanish (L1) proficiency was related to less volume in the bilateral globus pallidus, and higher English (L2) proficiency and earlier English AoA were related to greater volume in the right thalamus, left accumbens, and bilateral globus pallidus. For monolinguals, higher English proficiency was associated with greater volume only in the right pallidum. These results suggest that subcortical gray matter structures are related to the learning of a second language. Future research is encouraged to understand subcortical adaptation in relation to L1 and L2 acquisition from a developmental perspective.

期刊介绍： An interdisciplinary journal, Brain and Language publishes articles that elucidate the complex relationships among language, brain, and behavior. The journal covers the large variety of modern techniques in cognitive neuroscience, including functional and structural brain imaging, electrophysiology, cellular and molecular neurobiology, genetics, lesion-based approaches, and computational modeling. All articles must relate to human language and be relevant to the understanding of its neurobiological and neurocognitive bases. Published articles in the journal are expected to have significant theoretical novelty and/or practical implications, and use perspectives and methods from psychology, linguistics, and neuroscience along with brain data and brain measures.
