EEG Power Spectra of Children with Dyslexia, Slow Learners, and Normally Reading Children with ADD during Verbal Processing.

Electroencephalographic (EEG) power spectra were studied in two poor reader groups (dyslexia and slow learning) and a normal reading group with attention deficit disorder (ADD). In correlational analyses, the combination of greater low beta and less theta power significantly predicted better reading and spelling. Results suggest adequate readers process stimuli more actively than do poor readers. (DB)
