From VOA Learning English, this is the Technology Report.
Dyslexia is a learning disorder, it interferes with the ability to recognise words, and for some readers to understand what they have read.
Experts say dyslexia affects about five to ten percent of the population of the United State. Researchers have long known that people with dyslexia write or read words and letters backwards in the wrong order.

But a new study shows that people with dyslexia may have trouble redirecting their attention between senses, from seeing something to hearing something. The study suggests something that might help dyslexic people learn more quickly - play video games.
Vanessa Harrar of Britain's University of Oxford led the study. She reported the findings in the journal Current Biology. The study suggests that dyslexic people may have trouble moving quickly from what they read to what they hear. Doctor Harrar calls this a "sluggish shifting of attention across the senses."
"So, if you are trying to read something and then trying to listen to somebody who's reading aloud and you're trying to follow along with what they are reading -- they have to switch their attention from hearing what they are saying to looking at the piece of paper and back again. So we found they have quite sluggish shifting of attention across the senses," said Harrar.
In the study, Doctor Harrar tested 17 people with dyslexia, and 19 others without reading problems. The volunteers were asked to push a button as quickly as possible when they heard a sound, saw a light or experienced both together. Doctor Harrar compared the speed of their reactions.
She found that people with dyslexia were just as fast as the others when they saw only a picture or heard only a sound. But the dyslexics had a slower reaction time when they heard a sound and saw a picture at the same time.
Doctor Harrar feels like playing action video games could help dyslexic people shift from seeing to hearing more quickly. She adds that images in video games force the eyes to move and focus quickly.
"Video game types of things pop out of here and there, they move your eyes around the screen quite quickly in response to things quite quickly, and the more you play a video game the faster you get that kind of thing. So, the video game is really training the attention system to move quickly," said Harrar.
The study also shows that dyslexic people have the most difficulty going between what they saw and what they heard, this may have an effect on how dyslexic children are taught how to read.
When children learn the alphabet，they usually see the letter first and then hear the sound, or they see and hear the letter at the same time. The study shows that dyslexics might learn more quickly if they hear the sound of a letter or word first before seeing it.

阅读障碍是一种学习障碍，能干扰人学习词汇的能力，有的阅读者还难以理解所阅读的东西。
专家称美国有5%到10%的人患有阅读障碍，研究者很早就知道，阅读障碍者在写单词或字母时顺序不对。
但一项新研究发现患有阅读障碍的人可能在将注意力从不同感官之间转移会有困难，比如从看东西转为听东西。研究发现玩视频游戏可能帮助阅读障碍者快速学习。
英国牛津大学的凡妮莎·哈拉是这项研究的负责人，她的研究结果发表在《当代生物学》上。研究表明阅读障碍者可能在从所阅读的东西快速转向听的东西上有困难，哈拉博士称这是“跨感官注意力转移迟缓”。
“如果你一边阅读一边听别人大声朗读，你想听清楚他们在读什么，就必须将注意力从听转移到阅读，周而复始。我们发现这些人在将注意力从感官之前切换迟缓。”
在这项研究中，哈拉博士测试了17名阅读障碍患者和另外19名正常阅读者。这些志愿者们被要求在听到声音、看到灯或两者同时发生时按下按钮。哈拉博士将他们的反应速度进行对比。
她发现，在只看到图片或只听到声音时，阅读障碍者和其他人的反映速度一样。但在声音和图片同时出现时，阅读障碍者反应较迟缓。
哈拉博士认为玩视频游戏可能帮助阅读障碍者将看快速切换到听，她说视频游戏中的图像迫使眼睛移动，快速关注图像。
“视频游戏上会不停地跳出图像来，让你的眼睛在屏幕上快速转动，快速反应，玩游戏越快，就越能赶得上。所以视频游戏确实能锻炼注意力系统快速反应。”
研究还表明，阅读障碍者从看切换到听最困难，这可能会影响到教育阅读障碍儿童阅读的方法。
当孩子学习字母表时，他们通常会先看到字母，然后听到声音，或者同时看到和听到。这项研究表明如果阅读障碍者在看到字母或单词前先听到它，那可能就学得快些。
