Research into bilingual language production has identified a language control network that subserves control operations when bilinguals produce speech. Here we explore which brain areas are recruited for control purposes in bilingual language comprehension. In two experimental fMRI sessions, Dutch-English unbalanced bilinguals read words that differed in cross-linguistic form and meaning overlap across their two languages. The need for control operations was further manipulated by varying stimulus list composition across the two experimental sessions. We observed activation of the language control network in bilingual language comprehension as a function of both cross-linguistic form and meaning overlap and stimulus list composition. These findings suggest that the language control network is shared across bilingual language production and comprehension. We argue that activation of the language control network in language comprehension allows bilinguals to quickly and efficiently grasp the context-relevant meaning of words.
双语语言产生的研究已经确定了一个语言控制网络，该网络在双语者产生言语时辅助控制操作。在这里，我们探讨了双语语言理解中哪些大脑区域被招募用于控制目的。在两个实验 fMRI 会话中，荷兰语-英语不平衡双语者阅读了在两种语言中具有不同跨语言形式和意义重叠的单词。通过在两个实验会话中改变刺激列表组成，进一步操纵了控制操作的需求。我们观察到双语语言理解中的语言控制网络作为跨语言形式和意义重叠以及刺激列表组成的函数而被激活。这些发现表明语言控制网络在双语语言产生和理解中是共享的。我们认为，语言理解中语言控制网络的激活使双语者能够快速有效地理解单词的上下文相关意义。
