回答题：Easy Learning Students should be jealous． Not only do babies get to doze their days away, but they've alsomastered 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 simplewords．Marie Cheour at the University of Turku in Finland suspected that they mightprogress this fast because they learn language while they sleep as well as whenthey are awake．
To test the theory, Cheour and her colleagues studied 45 newborn babies in the firstfew days of their lives． They exposed all the infants to an hour of Finnishvowel sounds -- one that sounds like "oo", another like"ee" and a third boundary vowel peculiar to Finnish and similar languagesthat sounds like something in between． EEG recordings of the infants brainsbefore and after the session showed that the newborns could not distinguish thesounds．
Fifteen of the babies then went back with their mothers, while the rest were split intotwo sleep-study groups． One group was exposed throughout their night-timesleeping hours to the same three vowels, while the others listened to other,easier-to-distinguish vowel sounds．
When tested in the morning, and again in the evening, the babies who'd heard thetricky boundary vowel all night showed brainwave activity indicating that theycould now recognize this new sound They could identify the sound even when itspitch was changed, while none of the other babies could pick up the boundaryvowel at all．
Cheour doesn't know how babies accomplish this night-time learning, but she suspectsthat the special ability might indicate that unlike adults, babies don't"turn off" their cerebral cortex while they sleep． The skill probablyfades in the course of the first year of life, she adds -- so forget the ideathat you can pick up tricky French vowels as an adult just by slipping alanguage tape under your pillow． But while it may not help grown-ups, Cheour ishoping to use the sleeping hours to give remedial help to babies who aregenetically at risk of language disorders．
