Abstract

The present article reviews a series of selected functional and structural magnetic resonance imaging (MRI) studies focusing on the neuroplasticity of second language vocabulary acquisition as a function of linguistic experience. A clear-cut picture emerging from the review is that brain changes induced by second language vocabulary acquisition are observed at both functional and structural levels. Importantly, second language experience is even able to shape brain structures in short-term training of a few weeks. The evidence that linguistic experience can sculpt the brain in late second language learners, and even solely after a short-term laboratory training, constitutes a strong argument against theoretical approaches postulating that environmental factors are relatively unimportant for language development. Rather, combined neuroimaging data lend support to the determining role of linguistic experience in linguistic knowledge emergence during second language acquisition, at least at the lexical level.

二语词汇习得的神经可塑性

本文回顾了一系列功能性和结构性磁共振成像(MRI)研究，重点关注第二语言词汇习得的神经可塑性作为语言经验的功能。从这篇综述中得出的一个清晰的结论是，第二语言词汇习得引起的大脑变化在功能和结构两个层面都可以观察到。重要的是，第二语言体验甚至能够在几周的短期训练中塑造大脑结构。语言经验可以塑造晚期第二语言学习者的大脑，甚至仅仅经过短期的实验室训练，这一证据有力地反驳了假设环境因素对语言发展相对不重要的理论方法。相反，综合神经影像学数据支持语言经验在第二语言习得过程中的语言知识产生中的决定性作用，至少在词汇水平上是这样。

期刊介绍： LIA is a bilingual English-French journal that publishes original theoretical and empirical research of high scientific quality at the forefront of current debates concerning language acquisition. It covers all facets of language acquisition among different types of learners and in diverse learning situations, with particular attention to oral speech and/or to signed languages. Topics include the acquisition of one or more foreign languages, of one or more first languages, and of sign languages, as well as learners’ use of gestures during speech; the relationship between language and cognition during acquisition; bilingualism and situations of linguistic contact – for example pidginisation and creolisation. The bilingual nature of LIA aims at reaching readership in a wide international community, while simultaneously continuing to attract intellectual and linguistic resources stemming from multiple scientific traditions in Europe, thereby remaining faithful to its original French anchoring. LIA is the direct descendant of the French-speaking journal AILE.
