Why bilinguals are smarter?
I found the study conducted by the psychologists Ellen Bialystok and Michelle Martin Rhee to ask bilingual and monolingual preschoolers to short circles and red squares presented on a computer screen into two digital bins — one marked with a blue square and the other marked with a red circle. The result that the bilinguals were quicker at performing the second task is surprising. The bilinguals are better trained for the executive function in brain, which directs the attention processes for planning, solving problems and performing mentally demanding tasks.
Another article" Are bilinguals really smarter?" illustrated a good example for bilinguals to be more beneficial. When the monolingual look at the dog, they say dog. However, a bilingual have two alternative present themselves. The tiny decision making process for choose the correct dog word makes them smarter.
