Hemispheric specialization for speech production and perception in stutterers

Abstract A group of stutterers was tested on presumed indices of hemispheric specialization for speech production (pursuit auditory tracking) and speech perception (dichotic listening). Previous studies of normal subjects [18, 19] have revealed a significant right ear advantage (REA) for tracking with a speech articulator but not with manual tracking. Stutterers showed no significant REA in either tracking condition, but did show a significant REA, similar to that of normal speakers, in dichotic listening. Results were considered to differentiate this population of stutterers from normals in terms of hemispheric specialization for speech production but not for speech perception.
