sing only one language) and seniors who are bilingual. The team established that years of bilingualism change how the brain carries out tasks that require concentrating on one piece of information without being distracted by other information. This makes the brain more efficient and economical with its resources. To arrive at this finding, the team asked two groups of seniors (one of monolinguals and one of bilinguals) to perform a task that involved focusing on visual information (the color of an object) while ignoring spatial information (the position of the object). The researchers pared the works between different brain areas as people did the task. They found that monolinguals recruited a larger circuit with multiple connections, whereas bilinguals recruited a small circuit that was more appropriate for the required information. These findings were published in the Journal of Neurolinguistics. ―After years of daily practice managing interference between two languages, bilinguals bee experts at selecting relevant information and ignoring information that can distract from a task. In this case, bilinguals showed higher connectivity between visual processing areas located at the back of the brain. This area is specialized in detecting the visual characteristics of objects and therefore is specialized in the task used in this study. These data indicate that the bilingual brain is more efficient and economical, as it recruits fewer regions and only specialized regions,‖ explained Dr. Ansaldo, the head of the team. Bilinguals therefore have two cognitive (connected with mental processes of understanding) benefits. First, having more centralized and specialized functional connections saves resources pared to the multiple and more diverse brain areas allocated by monolinguals to acplish the same task. Second, bilinguals achieve the same result by not using the brain’s frontal regions, which are vulnerable to aging. This may explain why the brains of bilinguals are better equipped to stave off(to delay sth.) the signs of cognitive aging or dementia (a serious mental disorder caused by brain disease or injury). All the benefits of bilingualism have yet to be discovered. 27. According to the passage, which of the following statements is NOT true? A.
