Caption :. Credits :. About 5 to 10 percent of American children are diagnosed as dyslexic. Historically, the label has been assigned to kids who are bright, even verbally articulate, but who struggle with reading — in short, whose high IQs mismatch their low reading scores.
On the other hand, reading troubles in children with low IQs have traditionally been considered a byproduct of their general cognitive limitations, not a reading disorder in particular.
Now, a new brain-imaging study challenges this understanding of dyslexia. Rhymes and results The researchers recruited children, from 7 to 17 years old. According to a simple reading test and an IQ measure, each child was assigned to one of three groups: typical readers with typical IQs; poor readers with typical IQs; and poor readers with low IQs.
All were shown pairs of words and asked to judge whether the words rhymed. Using functional magnetic resonance imaging fMRI , the researchers observed the activity in six brain regions known to be important for reading. She graduated from the University of Pittsburgh in with degrees in neuroscience and English.
