Dyslexia is a learning disorder, it interferes with the ability to recognize 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 States. Researchers have long known that people with dyslexia write or read words and lettersbackwards 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 dyslexicpeople learn more quickly - play video games.

Vanessa Harrar of Britain’s University of Oxford led the study. She reported the findings in the journalCurrent Biology. The study suggests that dyslexic people may have trouble moving quickly from what they read to what they hear.

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 Dyslexicshad a slower reaction time when they heard a sound and saw a picture at the same time, this may have an effect on how dyslexic children are taught how to read.

Doctor Harrar feels like playing 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. 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.
