Cognitive Benefits of Bilingualism across the Lifespan

This paper reviews the effects of bilingual learning on human cognitive abilities and compiles relevant research results. The cognitive advantages of bilinguals over monolinguals are revealed through the exploration of memory, attention regulation and cognitive switching. In addition, the article analyses in depth the close connection between language and cognition, as well as the impact of bilingual learning at different ages, especially on children. Finally, the impact of bilingual learning on brain mechanisms is explored, highlighting the importance of left-right brain coordination and networked representation of language functions. These studies provide an important theoretical and practical basis for a deeper understanding of the benefits of bilingual learning.
