Research is reviewed concerning the current state of knowledge about normal hemispheric specialization; distinctions among such terms as dominance, laterality, and lateralization; and models of abnormal cerebral organization in dyslexic children. The question of dyslexic subtypes is undertaken along such dimensions as handedness, eyedness, and…

This review of the literature on laterality research concludes that, despite advances in the classification accuracy of laterality methods, definitive conclusions about hemispheric specialization in individual cases of dyslexic children cannot be drawn. Event-related measurements of cerebral metabolism promise to complement but not replace…
