Speaking with an accent of the non-target language enhances language control in bilinguals
摘要
Research has shown that bilinguals unconsciously produce more accented speech when encountering cross-language interference. In this study, we examined whether intentionally utilizing accent strategies, occurring in daily life, can help reduce these interferences. We recruited 36 unbalanced Chinese-English bilinguals to name pictures with a standard accent or the non-target language accent in both single- and dual-language contexts and applied linear mixed-effects models to examine the effects of accent strategies on switching and mixing costs. Our results showed that producing words with non-target language accents decreased switching and mixing costs. Conversely, speaking right after using an accent of the non-target language increased switching and mixing costs. These results suggest that accent strategies may facilitate the target language production through efficiently suppressing the non-target language at global and local levels. This study provides initial evidence of accent strategies on bilingual language control, shedding light on lexical access mechanisms during bilingual language production. It emphasizes the role of intentional strategy selection, thereby expanding on the adaptive control hypothesis.
