Dyslexia is one of the most prevalent disabilities affecting American school children. Between 8% and 10% of American children have dyslexia, and more than 10% of other children are at risk of identification.

The question addressed in this lecture is why children have dyslexia. Dr. Kearns will explain how children with this language-based learning disability have brains that process specific tasks differently and how this relates to their performance on reading-related tests. In addition, he will present other possible causes of word reading difficulty that can be confused with dyslexia. He will also address controversies about dyslexia—including why some people do not even like the word. The goal of the lecture is to help people understand what dyslexia is and what it is not.
