But what happened when these babies accustomed to English heard Spanish? The 12­month­olds studied the mouth longer, just like younger babies. They needed the extra information to recognize the unfamiliar sounds. That fits with research into bilingualism (双语) that shows babies' brains adjust themselves to distinguishing the sounds of their native language over other languages in the first year of life.

　　The continued lip­reading shows the 1­year­olds clearly still are fit for learning. Babies are so hard to study that this is “a fairly heroic data set”， says Duke University cognitive neuroscientist Greg Appelbaum, who found the research so fascinating that he wants to know more.
