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 dysphon
etic poor readers had lower beta values than adequate reading children
with Attention Deficit Disorder. This evidence indicates that poor re
aders, especially dysphonetics, were less actively engaged in the task
