Thirty-nine children, ranging in age from 7-0 to 10-11, were recorded during a contextual reading task and at rest. During reading, children with dyslexia were expected to show increased theta and beta amplitude compared to nondisabled readers. These differences were expected in regions of presumed strength for each subtype as a sign of overengagement in task. Children with phonological deficits (dysphonetic dyslexia) were expected to adopt visuospatial processing strategies (right occipital-parietal activation), those with orthographic deficits (dyseidetic dyslexia) to emphasize phonetic strategies (left temporal-parietal activation). Results supported beta frequency differences in anticipated regions by subtype during the reading task. However, the direction of difference hypothesis was not supported. Decreased amplitudes in both groups with dyslexia compared to normally achieving readers suggest reconceptualization of the theoretical base for the Boder subtyping system.<\/jats:p>","DOI":"10.1177\/002221949202500207","type":"journal-article","created":{"date-parts":[[2008,12,24]],"date-time":"2008-12-24T02:27:07Z","timestamp":1230085627000},"page":"133-141","source":"Crossref","is-referenced-by-count":34,"title":["Electrophysiological Correlates of Dyslexic Subtypes"],"prefix":"10.1177","volume":"25","author":[{"given":"Jane M.","family":"Flynn","sequence":"first","affiliation":[{"name":"Jane M.
