Bilingualism And Bilingualism

Decent Essays

Bilingualism carries broad appeal as a potential reserve variable because it is primarily influenced by environmental factors such as country of birth, emigration, or attendance in a second language school (Gold et al., 2013). Individuals become bilingual through these life circumstances and the environmental factors eventually contribute to the development and organization of brain reserve (Schweizer et al., 2012). The development of this reserve is thought to be directly correlated to the continuous monitoring of context that is necessary for language inhibition and activation (Gold et al., 2013). Research is finding that there is a delay of onset for lifelong bilinguals by 4.7 years for people with mild cognitive impairment and 7.3 years for people with Alzheimer’s disease. Research points to a substantial impact of bilingualism that both increases the ability to perform an important set of cognitive tasks and reorganizes neural networks recruited for that performance (Bialystok et al., 2014). Both languages of a bilingual speaker are constantly active to some degree, even in strongly monolingual contexts where there is no reason to expect use of the other language. This joint activation has profound implications for both linguistic and nonlinguistic processing. If both languages are active, then a problem in attention is introduced for a bilingual that does not exist for a monolingual speaker (Bialystok, 2011). The cognitive effects of bilingualism show a consistent
