Electroencephalographic power spectra were studied in two poor-reading adolescent groups (n=38), dysphonetic and phonetic. Significant Group x Hemisphere effects were found in the alpha and beta bands, with the phonetic group showing right greater than left asymmetry. Results suggest more circumscribed and mature processing in the phonetically…

Twelve males (ages 8-12) with phonological dyslexia were compared to 12 age-matched good readers and 12 reading-matched students. Results showed that dyslexia is not related to incomplete lateralization or to a failure to inhibit verbal processing in the right hemisphere during reading and writing. (Author/JDD)

This article presents evidence that initial and advanced reading abilities are predominantly mediated by the right and left cerebral hemispheres, respectively. Premature reliance on left hemisphere reading strategies or later failure to shift from earlier right hemisphere strategies are hypothesized as resulting in two different types of dyslexic…

Twenty children with left or right hemisphere dysfunction and 10 controls were administered a comprehensive neuropsychological evaluation. Results provide limited support for the hypothesis that the right hemisphere subserves attention and concentration but not for the hypothesis that right-hemisphere deficits are more frequently associated with…

A study provided hemisphere specific simulation and hemispheric alluding stimuli to 15 middle school students with L-type dyslexia and 15 with P-type dyslexia. Traditional decoding and comprehension exercises were provided to 15 students with M-type dyslexia. Readers with all types of dyslexia exhibited significant improvement in reading accuracy…

This article reviews Bakker's developmental neuropsychological model (the Balance Model) of reading development (EC 602 750), notes the need for validating research before employing these procedures in clinical practice, and raises some conceptual problems such as evidence that learning disability subtypes evolve over time.
