文献已经确定了许多重要的因素，影响双语者的语言依赖于特定大脑区域中相同的神经群的程度。这些因素包括第二语言（L2）的习得年龄，第一语言（L1）和L2的熟练程度，以及语言接触量等。目前缺乏的是一套全球性的原则，来解释多种因素与双语者神经解剖学上语言重叠程度的关系。我们提供了一套这样的原则，这些原则共同解释了已经单独而不是集体研究的众多数据来源：（1）L1和L2之间的习得相似性原则，（2）L1和L2之间的语言相似性原则，以及（3）认知控制和努力原则。参考双语者语言组织的广泛特征，如原则所示，可以为未来的临床和基础科学研究提供路线图。
The literature has identified many important factors affecting the extent to which languages in bilinguals rely on the same neural populations in the specific brain region. The factors include the age of acquisition of the second language (L2), proficiency level of the first language (L1) and L2, and the amount of language exposure, among others. What is lacking is a set of global principles that explain how the many factors relate to the degree to which languages overlap neuroanatomically in bilinguals. We are offering a set of such principles that together account for the numerous sources of data that have been examined individually but not collectively: (1) the principle of acquisition similarity between L1 and L2, (2) the principle of linguistic similarity between L1 and L2, and (3) the principle of cognitive control and effort. Referencing the broad characteristics of language organization in bilinguals, as presented by the principles, can provide a roadmap for future clinical and basic science research.
