Bilingual Brain - Arturo E. Hernandez

Hernandez will extend recent work that has begun to take a biological or natural systems approach. He proposes that, in bilinguals, two languages live inside a brain almost like two species live in an ecosystem. For the most part they peacefully co-exist and often share resources. But they also compete for resources, particularly when under stress. Although there are still many questions to answer and many puzzles to solve, Hernandez argues that the nonlinear dynamical models, which have been used to uncover the underlying mechanisms seen in natural systems and more recently in language and cognition, can be used to shed considerable light on the neural bases of bilingualism.
