小编摘要:诵读障碍也叫读写障碍症,是一种最常见的特殊学习困难,泛指在阅读、书写或拼字方面的障碍。爱迪生,爱因斯坦,毕加索等人就是读写困难症者。这些人在解决了这类障碍问题后,常常显示出在某一方面的独特的创造力。

导读:研究发现,患有读写障碍的人在声音识别上有很大困难,他们会极力从不熟悉的声音中寻找熟悉的声音。实验时,研究人员将30名年龄,受教育程度和智商相差不多的人分为两组,一组是有诵读障碍史的人,而另一组人没有。借助计算机的帮助,研究人员发现有读写障碍的人大脑中存在“声音盲点”,这便是他们在声音的区别上有困难的原因。

People with dyslexia struggle to recognise familiar voices, scientists suggest.

The finding is the first tentative evidence that small sounds in the human voice that vary between people are difficult for dyslexics to hear.

Writing in the journal Science, the scientists say that many people could have some degree of "voice blindness".

And by studying it, scientists hope to better understand how the human brain has evolved to recognise speech.

Humans rely on small sounds called phonemes to tell one person from another.

As we first try to form the word dog, for example, phonemes are the "duh"-"og"-"guh" sounds that our parents prompt us to make.

But as we master the ability to read, we become less reliant on recognising these sounds to read, and eventually stop noticing them.

Despite ignoring them, however, phonemes remain important for voice recognition.

The tiny inflections in the way people pronounce phonemes gives a listener cues to tell one voice from another.

Because people who suffer from dyslexia are known to struggle with phonemes when reading, a US-based team of scientists wondered whether they might also struggle hearing them in people's voices.
