Atypical Neural Functions Underlying Phonological Processing And Silent Rehearsal In Children Who Stutter, Christine Weber-Fox, John E. Spruill Iii, Rebecca M. C. Spencer, Anne Smith

Rebecca M. C. Spencer

Phonological processing was examined in school-age children who stutter (CWS) by assessing their performance and recording event related brain potentials (ERPs) in a visual rhyming task. CWS had lower accuracy on rhyming judgments, but the cognitive processes that mediate the comparisons of the phonological representations of words, as indexed by the rhyming effect (RE) ERP, were similar for the stuttering and normally fluent groups. Thus the lower behavioral accuracy of rhyming judgments by the CWS could not be attributed to that particular stage of processing. Instead, the neural functions for processes preceding the RE, indexed by the N400 and CNV …
