That's a pre-school child beating a drum, in sync with an adult drummer. And here's a pre-schooler who can't find the rhythm.
这是一位学前儿童和一位成年鼓手在一起打鼓的声音。下面是另一位学前儿童击打出的鼓声，他无法抓住节拍。
Researchers find that the first child, who can match the drum beat, is more likely to have better early language skills and reading potential. The study is in the Proceedings of the National Academy of Sciences.
科学家们发现，第一位能跟上节拍的孩子，其早期语言技能和阅读潜能可能更好。该研究发表在《美国国家科学学院院刊》上。
Rhythm is a key factor in communication. Speech rhythm provides important cues for meaning. Babies pick up rhythms, and we all use it to help identify syllables and words. An inability to properly process speech and sound—and rhythm—appears to be associated with reading problems.
节拍是交流的关键。言语节拍能为读懂言语提供重要线索。婴儿可以毫不费力地学会节拍，我们都用节拍来辨析音节和单词。不能恰当地处理语音、声音、及节拍——这和阅读障碍有关。
In the study, scientists tested 35 children between three and four years old. An adult drummer beat a tempo meant to mimic the speed of speech. Twenty-two children could beat along; 13 could not.The children who kept the beat were faster at naming objects and colors, had superior short-term auditory memory, and were better at rhythm and melody discrimination. These skills all are related to language and reading.
在该研究中，科学家对35位年龄为3至4岁的儿童进行了测试。实验中安排一位成年鼓手模仿语速进行击打。22位儿童能够跟着鼓手进行击打；而另外13位则不能。那些能跟着节拍击打的儿童能更快地说出目标物的名称和颜色，有更优越的短暂听觉记忆能力，而且更容易区分出节拍和节奏。这些技能均与言语和阅读有关。
The researchers suggest that such a drumming test could identify children with early language and literacy challenges. And training could help the kids overcome those challenges—in part by learning to keep a beat.
科学家指出，该击鼓测试可以辨别出哪些孩子具有早期语言技能和读写能力，哪些没有。在一定程度上，通过训练——学习如何保持节拍，则能够帮助这些孩子掌握上述技能。
