25.10It soundsalmost toogood tobe true,but anew studyon sleepingbrains suggeststhatlisteningtolanguages whileyou sleepcan actuallyhelp youto learnthem.For thestudy,researchers playedrecordings offoreign wordsand theirtranslations tosubjectsenjoying slow-wave sleep,a stagewhen aperson haslittle consciousnessof theirenvironment.Toensure that the resultswere notcompromised byforeign languagewords thatsubjects mayhavehad somecontact withatsomepoint intheir wakinglives,researchers madeup totallynonexistentforeign words.When the subjects wokeup,they werepresented withthe made-up wordsagain withouttheirtranslations.The subjectswere thenasked toimagine whetherthis made-up wordindicated an（模糊的）object thatwas eithersmaller orlarger.This vagueway oftesting theirunderstanding ofthewords isan approachthat issupposed totap intothe unconsciousmemory.Unbelievably,thesubjectswere ableto correctlyclassify thewordsinthis wayat anaccuracyrate thatwas10percent higherthan randomchance.Thats nota ratehigh enoughtohavethemsuddenly communicatinginaforeign tongue,but itis enoughto suggestthatthebrain isstillabsorbing informationon somelevel,even duringsleep.。
