EEG power spectra of dysphonetic and nondysphonetic poor readers

Two subtypes of poor readers, dysphonetic and phonetic, were compared on EEG spectral values obtained as they viewed strings of letters and short words. Dysphonetic poor readers had significantly higher values than phonetics in the theta and delta bands. Both phonetic and dysphonetic poor readers had lower beta values than adequate reading children with Attention Deficit Disorder. This evidence indicates that poor readers, especially dysphonetics, were less actively engaged in the task.
