在与他人交流时，双语者可能会仅使用一种语言，也可能会根据自己意愿交替使用两种语言。无论哪种情况，他们很少会错误的使用非目标语言，并且很容易理解切换了语言的语句，在语言表达和理解方面都表现出强大的语言控制能力。单独对语言表达或理解进行的研究表明，双语者在这两个过程中依赖不同的的语言控制机制。然而，在现实生活中（例如在对话中），双语者常在在理解和表达任务之间来回切换。在这种情况下，他们可能会在这两类任务中使用一种共同的机制来提高语言加工的效率。本次介绍的几项研究着重探讨了双语者在不同情况下如何在语言理解和表达任务中适应性地控制两种语言。
When communicating with others, bilinguals may stick to one language or alternate two languages at will. In either case, they rarely produce the unintended language by accident and easily follow language switches, showing remarkable language control abilities in both language production and comprehension. Studies on language switching within production or comprehension suggested that bilinguals rely on different and separate language control mechanisms in these two processes. Nevertheless, it is common that bilinguals alternate between comprehension and production in real life (e.g., in a conversation), and in this situation they may use a shared mechanism across these two processes to improve language processing proficiency. In this talk, I will introduce several studies that addressed how bilinguals adaptively control languages across comprehension and production in various contexts.

Dr. Li is an Assistant Professor at the Department of Psychiatry, University of California San Diego. She received a B.S. in Psychology from Beijing Normal University and a Ph.D. in Educational Psychology from the University of Maryland, College Park. Dr. Li’s research investigates the cognitive mechanisms that enable people to speak and read fluently, with a focus on how bilinguals prevent between-language interference. Her research covers the lifespan, revealing how language processing mechanisms vary in children, young adults, healthy older adults, and in Alzheimer’s disease. She has published 27 peer-reviewed papers in this topic (16 first author), and her research has been supported by multiple NIH grants.
