For bilinguals, speaking and listening are assisted by complex control processes including conflict monitoring and inhibition. However, the extent to which these processes adapt to linguistic and situational needs has been examined separately for language production and comprehension. In the present study, we use a dual-EEG to record the carry-over effects of language control on general cognitive control in three language contexts (single-first language [L1], single-second language [L2], and mixed). Chinese learners of English were placed in dyads in which one participant was asked to name pictures while the other listened. Interleaved after each naming/listening trial were flanker trials. The results from picture naming and listening revealed higher delta and theta synchronization in the single-L2 and mixed contexts compared with the single-L1 context and higher theta synchronization in the mixed context compared with the single-L2 and single-L1 contexts. The results from the interleaved flanker trials demonstrated that inhibition was adaptively generalized in the single-L2 and mixed contexts. Altogether, the findings support the natural adaptation of language control to cognitive control and underscore the importance of linguistic context. We argue that these adaptive patterns have the potential to affect corresponding control processes across language and cognitive control tasks.
Aims: Cross-language interference studies of language control mainly focus on the lexical level, whereas language control may occur at the smallest unit phonemic level of language. In the present study, we examined the role of language control during cross-language phoneme processing. Design: Participants used one language to name pinyin or alphabet in the single-language blocks, and they used two languages for naming in the mixed-language blocks. Data and analysis: Using a linear mixed-effects model, we built models for mixing costs and switching costs based on reaction times (RTs) and accuracy. Findings: Switching between Chinese (L1) and English (L2) phonetic symbols revealed both mixing and switching costs. Originality: The findings suggest that switching of cross-language phonemes requires not only global control of the non-target phonemes, but also local control of the non-target phonemes. Significance: Just as cross-language interference control occurs at the lexical level, this study demonstrates that control also occurs at the phonemic level.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
