TORONTO (Reuters) - Parents who spend time and money to teach their children music, take heart -- a new Canadian study shows young children who take music lessons have better memories than their nonmusical peers.
The study, to be published in the online edition of the journal Brain on Wednesday, showed that after one year of musical training, children performed better in a memory test than those who did not take music classes.
"(The research) tells us that if you take music lessons your brain is getting wired up differently than if you don't take music lessons," Laurel Trainor, professor of psychology, neuroscience and behavior at McMaster University in Hamilton, Ontario, told Reuters.
"This is the first study to show that brain responses in young, musically trained and untrained children change differently over the course of a year," said Trainor who led the study.
Over a year they took four measurements in two groups of children aged between four and six -- those taking music lessons and those taking no musical training outside school -- and found developmental changes over periods as short as four months.
The children completed a music test in which they were asked to discriminate between harmonies, rhythms and melodies, and a memory test in which they had to listen to a series of numbers, remember them and repeat them back.
Trainor said while previous studies have shown that older children given music lessons had greater improvements in IQ scores than children given drama lessons, this is the first study to identify these effects in brain-based measurements in young children.
She said it was not that surprising that children studying music improved in musical listening skills more than children not studying music.
"On the other hand, it is very interesting that the children taking music lessons improved more over the year on general memory skills that are correlated with nonmusicalabilities such as literacy, verbal memory, visiospatial processing, mathematics and IQ," she said.
音乐培训有利于提高儿童的记忆力
多伦多（路透社）— 花费金钱和时间让孩子们学习音乐的家长们注意了，这里有一条振奋人心的消息：加拿大一项新的研究显示，学习音乐的儿童比不学音乐的同龄儿童拥有更好的记忆力。
这项将要发表于周三《Brain》杂志网络版的研究通过一种记忆测验证实，经过1年音乐培训的儿童的记忆力比未经培训的儿童要好。
安大略省麦马斯达大学心理学、神经科学和行为学教授劳雷尔·特莱诺尔对路透社记者说，“研究告诉我们，音乐培训能够让你的大脑的发育与众不同。”
研究主持者特莱诺尔说：“这项研究首次证实，经过一年的音乐培训后，受训与未受训儿童大脑的反应有所不同。”
研究人员把一群4到6岁的儿童分为两组，其中一组接受音乐培训，另一组不接受任何校外音乐培训。在一年中，分别进行四次测试，在仅仅4个月后，就发现孩子们的大脑发育出现差别。
在音乐测试中，这些儿童必须分辨出不同的和弦、节奏和旋律；在记忆测试中，他们必须将听到一串数字记住并重复出来。
特莱诺尔说之前曾有关于较大儿童的研究显示，学习音乐的儿童比学习戏剧的儿童的IQ得分高，此次研究首次证实了音乐儿童大脑功能的影响。
她说，毫无疑问，学习过音乐的儿童在听音乐的技巧方面比没学过的儿童要强。更重要的是，学过音乐的儿童在非音乐方面的进步也更快，比如读写、背诵、视觉处理、数学和IQ得分等。”
