With the development of globalization, more and more people begin to learn and use a second language. For bilinguals who juggle two languages in their mind, one of the most compelling findings in recent bilingual research is that both languages are activated in parallel during bilingual language production. Therefore, language control is recruited to detect and resolve cross-language conflicts. Previous studies have examined the cognitive and neural mechanisms of bilingual language control, but few of them have captured how different brain areas interact with each other. In the first part of her talk, Dr. Guo will present recent fMRI results on brain activation patterns of language control using multivoxel pattern analysis (MVPA). The results showed that several brain regions including the dorsal prefrontal cortex, supplementary motor area, and anterior cingulate cortex were associated with language control. She will then talk about modeled causal interactions of these brain areas using an extended unified structure equation model (euSEM)-based effective connectivity analysis, and how the neural network of language control adapts to different language contexts. In the second part of her talk, she will present some recent work on the relationship of domain-general cognitive control and language
control in bilinguals' speech production.
