The benefits of bilingualism on the brain of the speaker are plentiful. Studies have shown that speaking a second language slows down the deterioration of the brain in aging, can help to delay the onset of dementia and boosts executive function. Studies have explored the relationship between bilingualism and working memory. Working memory involves the information that can be processed ad retained by the brain in relation to immediate tasks. It is essentially at play when an individual is following instructions, understanding an argument or solving a math problem.
Learning and speaking a second language demands a strong working memory function, as switching between languages, formulating ideas within a different language and translating thoughts all require the ability to retain and spontaneously process immediate information.
Studies compare the working memory of small children with a range of tests, involving for example the recollection of a set of numbers or the repetition of those numbers backwards. Children who spoke a second language revealed better results than their monolingual counterparts, as well as exhibiting an ability to manage a heavier cognitive load. Similar studies have been performed with adults, yielding similar results.
For those questioning the benefits of bilingualism, evidence such as this reveals the significant effect it has on the fitness of the brain. Working memory is an crucial function for processing information and responding to the world across all areas of life. Keeping this function fit and well-trained is essential, and what better and more engaging way to do it than with a second language?
