The study reminds us how important it is to consider the experience of being bilingual; it is not terribly constructive to lump all bilingual studies together and make generalized evaluations. If you do want to lump them together, it’s worth remembering that regardless of proclaimed cognitive or anatomical advantages, bilinguals have twice as many communities to interact with, cultures to experience, and newspapers to read. And if that isn’t an advantage, what is? Millions of people study English as a second language every year for precisely these reasons (in fact, there are approximately three times as many non-native as native English speakers).
