The youngsters, who were aged from three to seven months, then had their brains scanned as various familiar noises were played while they slept.
然后研究人员在这些三至七个月大的小孩睡觉时对他们的脑部进行扫描,同时播放各种各样熟悉的声音。
The first experiment looked at whether the tots could tell the difference between human and non-human noises.
在第一个试验中,研究人员观察这些幼儿能否区分人类和非人类发出的声音。
This revealed that coughing, sneezing, yawning, lappingwater reminiscent ofbath time and the squeaking of toys all activated a part of the brain known to process speech. But human sounds lit it up far more.
研究发现,咳嗽、打喷嚏、打哈欠、让人联想到洗澡的冲水声、玩具发出的吱吱声都会激活婴儿负责语音处理的大脑部位。但是人类的声音对这一部位的影响尤为明显。
The researchers then checked whether the babies' brains reacted differently to happy, sad and neutral noises.
之后,研究人员查看婴儿的大脑是否会对快乐、悲伤和平和的声音做出不同反应。
This time, a brain area linked to emotion sprung to life, with crying triggering it more than laughter or neutral sounds, the journal Current Biology reports.
据《当代生物学》杂志的报道,这一次,和情感相关的大脑区域变得活跃起来,其中哭声引起的反应比笑声或平和的声音引起的反应要大得多。
