Not only do babies get to doze their days away, but they ve also mastered the fine art of learning in their sleep. By the time babies are a year old, they can recognize a lot of sounds and even simple words. Marie Cheour at the University of Turku in Finland suspected that they might progress this fast because they learn language while they sleep as well as when they are awake. To test the theory, Cheour and their colleagues studied 45 newborn babies in the first days of their lives. They exposed all the infants to an hour of Finnish vowel sounds one that sounds like oo, another like ee and the third boundary vowel peculiar to Finnish and similar languages that sounds like something in between. EEGrecording of the infants brains before and after the session showed that the newborns could not distin-guish the sounds. Fifteen of the babies then went back with their mothers, where the rest were split in-to two sleep-study groups. One group was exposed throughout their night-time sleeping hours to the same three vowels, while the others listened to the other, easier-to-distin-guish vowel sounds. |
