MRI studies are actually not the gold standard for information about dyslexia rather they offer supporting evidence for results obtained in more conventional ways. Consider that all the children in MRI dyslexia studies are actually put into groups determined by pen and paper test combined with oral tests. I am at a loss as to why the media puts these MRI dyslexia studies as a source of primary information when they are really just supporting previous research conclusions. I posted an article in Aug/2006 that was based on years of earlier studies that basically said that dyslexia and IQ were not related. There were also some good studies that identified lower IQ dyslexics and determined that they benefited from dyslexia intervention as much as the higher IQ dyslexics did. Here is the article I wrote in 2006 dyslexiaglassescom/dyslexia_myths_revisited.html . It was based on information available for many years before 2006.
