Research suggests that dyslexic adults struggle to focus due to excessive external noise, leading to impaired reading skills. This study confirms the hypothesis that dyslexia is linked to difficulty filtering out background information.
A recent brain-imaging study challenges the historical understanding of dyslexia by showing that children with reading difficulties have the same brain difficulty in processing sounds regardless of their IQ. This finding could change the way educators help poor readers, as all can benefit from the same interventions.
Researchers used fMRI to compare brain activation patterns of poor readers with and without low IQs. Both groups showed reduced activations in left inferior parietal lobule and fusiform gyrus, indicating impaired phonological processing. This study provides biological evidence against using IQ to diagnose dyslexia.
