Dyslexia is not related to IQ, study shows
NEWS IN BRIEF — Posted Nov. 14, 2011
There is no association between dyslexia and an individual's IQ, according to a National Institutes of Health study published online Oct. 17 in Psychological Science.
Researchers used magnetic resonance imaging to measure the brain activity of 131 students ages 7 to 16 at schools in the Pittsburgh and San Francisco Bay areas. The children were divided into three groups: typical readers with typical reading and IQ scores; poor readers who have typical IQ scores; and poor readers with low IQ scores.
Researchers examined participants' brain activity as the youths looked at pairs of words on a computer screen and indicated whether or not they rhymed. The study found that children with dyslexia had the same pattern of brain activity regardless of their IQ score (link).
