Abstract:Studies on bilingual control suggest that different experimental contexts (single and dual lan-guage context) lead to different neural loci at which words in the target language are retrieved in different ways. However, these researches neglect the effect brought about by the community context, in which everyday-use language is formed. This comparative study between speakers from code-switching and non-code-switching communities can shed some light on the understanding of cortical, sub-cortical and cerebellar structures involved in bilingual control when speaking, thus revealing neural circuit and neural loci involved in language control generally.
