title: Dichotic listening to temporal tonal stimuli by good and poor readers.
abstract: The hypothesis that reading disability is associated with impairment in the lateralization of temporal stimuli was tested by presenting 123 good- and poor-reading boys (Grades 4 through 6) with dichotic sets of temporal and nontemporal tonal stimuli for recognition. Reading ability was assessed by measuring proficiency in reading consonants, vowels, words, sentences and short stories. On the tone test, good readers showed a right-ear advantage in reporting the temporal stimuli, and a left-ear advantage in reporting the nontemporal stimuli. Poor readers showed the reversed pattern of response. Since right-ear advantage in report of given stimuli indicates left-hemispheric dominance for processing those stimuli, the data seem to suggest a link between reading disability and left-hemispheric dysfunction in processing temporal stimuli.
