Research Abstract

Compared with monolinguals, bilinguals show advantages in certain cognitive functions. The present study focused on the relationship between the cognitive advantages of bilinguals and mechanisms that diminish cross-language interference. I investigated neural mechanisms that underlies the diminishment of cross-language interference in the language processing of bilinguals with behavioral studies and brain imaging studies. The results revealed:
1. A factor that lightens cognitive load during speech and its neural mechanism.
2. A factor that underlies diminishment of cross-language interference during reading and its neural mechanism.
