A Biological Mechanism For Dyslexia

Posted February 20, 2013 10:50 AM

From Science 2.0:

By recording the automatic brain wave responses of 100 school-aged children to speech sounds, researchers found that the very best readers encoded the sound most consistently while the poorest readers encoded it with the greatest inconsistency.

Decades of research from laboratories worldwide have shown that reading ability is associated with auditory skills, including auditory memory and attention, the ability to rhyme sounds and the ability to categorize rapidly occurring sounds.

Presumably, the brain's response to sound stabilizes when children learn to successfully connect sounds with their meanings. While learning to read is a smooth process for most children, some suffer from dyslexia, a constellation of impairments that make learning to read difficult. A newly discovered biological mechanism appears to play an important role in the reading process and could lead to helping people with dyslexia.
