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…

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.

The commentary concludes that the data presented by Sawyer do not support the interpretation that reading comprehension…

This article argues for the adoption of a 2-step procedure in diagnosing dyslexia: first, identify students with word list reading standard scores below 90, and then identify students with a reading score at least 10 points lower than expected from the full scale intelligence quotient. (JDD)
