Document Summary
Summary bialystok bilingualism: consequences for mind and brain. More than half of the world"s population is bilingual, w/ higher rates (56%) in european countries. Accumulating evidence suggests that the development, efficiency and decline of crucial cognitive abilities are different for bilinguals than monolinguals functional neuroplasticity. Bilingual children are superior on a range of tasks, especially those involving symbol manipulation and reorganization. Significant advantage in meta-linguistic awareness, but also non-verbal problems requiring participants to ignore misleading info. Verbal skills in bilinguals is generally weaker in each language, than monolinguals. Bilinguals also show systematic deficits in verbal fluency tasks. Bilinguals at all ages showed better executive control than monolinguals. This advantage has been shown to extend into older age and protect against cognitive decline. Evidence has shown that the bilingual mind does not represent the two languages as two independently-represented language systems some measure of activation of both languages and some interaction between them at all times.
