This study examined the hypothesis that spelling errors involving vowels are linked to difficulties in vowel perception. Second to fourth graders (n=155) were grouped by reading skill and given vowel discrimination and identification tasks. Vowel identification errors were linearly associated with reading skill and with vowel spelling errors.…

To investigate the relationship between reading accuracy and speech processing, 20 skilled readers (grades 2-3) were compared with 20 less skilled readers on a speech perception and production task. The vowel phonemes were less securely represented in the perceptual systems of the less skilled readers than were consonant phonemes. (Author/CR)

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…
