本研究探讨了终身双语可能会提高思维模式转换能力的可能性。比较单语和流利双语大学生在任务转换范式下的表现。与单语者相比，双语者在任务转换范式中的转换成本更低，这表明终身的语言转换经验可能有助于提高效率，在思维模式之间灵活转换的能力。另一方面，双语者和单语者在执行混合任务和单一任务块的差异成本上并没有什么不同。这些结果表明，双语在执行功能上的优势很可能不仅仅局限于抑制竞争反应，还包括灵活的心理转移。
This study investigated the possibility that lifelong bilingualism may lead to enhanced efficiency in the ability to shift between mental sets. compared the performance of monolingual and fluent bilingual college students in a task-switching paradigm. Bilinguals incurred reduced switching costs in the task-switching paradigm when compared with monolinguals, suggesting that lifelong experience in switching between languages may contribute to increased efficiency, in the ability to shift flexibly between mental sets. On the other hand, bilinguals did not differ from monolinguals in the differential cost of performing mixed-task as opposed to single-task blocks. Together these results indicate that bilingual advantages in executive function most likely extend beyond inhibition of competing responses, and encompass flexible mental shifting as well.
