Neuroscience:儿时玩乐器老来听力佳

2013-11-07 koo 生物360

父母们在孩子的音乐课程和乐器上花费了大量金钱后,经常会失望地看到这些长笛、单簧管和小提琴被孩子们随便放弃了。不过,在音乐早期教育上的投资也许并没有浪费。新的研究表明,即使几十年没有练习弹奏乐器,这些放弃音乐之路的“音乐家”仍有着更灵敏的耳朵。 【原文下载】据ScienceNow报道,为了比较曾经的“音乐家”和从未弹奏过乐器的人的听力,研究人员测量了一种被称为“神经定时”的听觉处理过程所产

据ScienceNow报道,为了比较曾经的“音乐家”和从未弹奏过乐器的人的听力,研究人员测量了一种被称为“神经定时”的听觉处理过程所产生的脑电活动,该过程可以使人们对声音的瞬间改变(例如从辅音到元音的过渡)作出反应。随着年龄的增长,该能力会逐渐下降,而它是解释语音的关键,因此对老人说话需要语速缓慢,有时还要重复。

与那些未上过音乐课的同龄人相比,55岁至76岁的曾在年轻时学过音乐4到14年的人群,有着更加精确的“神经定时”能力,即使他们已经近40年未练习过乐器。

11月5日,研究团队将报告发表在《神经科学杂志》上。研究人员称,研究发现,参与者曾经在弹奏乐器上花费的时间越长,他们大脑的反应越灵敏。尽管之前的研究已经表明弹奏音乐可以改善听力功能,研究人员称,这是首次发现音乐有如此长期的益处。
