Until recentlS researchers thought the bilingual advantage stemmed primarily from an ability for l.nftlbrtion that was honed by the exercise of suppressing one language system: this suppression-, it was thought, would help train the biliugual i, hftp://www.nytimes.com/2012/O j/l8/opinion/sundoy/the-benefits-of-bilinguotism.html?_t=2&src=me&re!generol .t mind to ignore distractions in other contoGs.

Biliufualisms effects also extend into the twilight years. Iu a recent stu y of 44 elderly Spauish-English biliuguals, scientists led by the neuropsychologist Tamar Gollan of the University of California, San Diego, found that individuals with a higher degrte of biliugualism - measured lrough a comparative evaluation of proficieucy iu each language - were more resistant than others to the onset of dementia and ottrer symptoms of Alzheimer,s disease: the higher the degree of bilingualism, the laterthe age of onset Nobody ever doubted the power of language.

It requires keeping track of changes around you in the same way that we mouitor our surroundings when driving. In a study comparing German-Italian bilinguals with Italian monolinguals on monitoring tasks, Mr. Costa and his colleagues found that the bilingual subjects not only performed better, but they also did so with less activity in parts of the brain involved in monitoring, indicating that they were more efEcient at it. The bilingual experieuce appears to influence the brain from iufancy to old age (and there is reason to believe that it may also apply to those who leam a second language [ater in life), In a zoog study led by Agnes Kovacs of the Interuational School for Advauced Studies in Trieste, Italy, 7-month-old babies exposed to two languages from birth were compared with peers raised with one language. In an initial set of trials, the infants were preseuted with an audio cue and tlen showu a puppet ou oue side of a screen. Both iufant groups learned to look at that side ofthe screen in anticipation ofthe puppet But in a later set oftrials, when the puppet begqn appearing on ttre opposite side of the screen, the babies exposed to a bilingual environment quickly learned to switch their anticipatory gaze in the new direction while the other babies did not. l.
