Fourteen right-handed stutterers and 14 normal speakers (7 men & 7 women) responded to monaurally presented stimuli with their right and left hands. Results of an ANOVA with repeated measures showed that a significant ear-hand interaction existed in the normal subjects' data, with the right-ear, right-hand configuration producing the fastest responses. These findings were in concert with an efficiency model of neurolinguistic organization that suggests that the left hemisphere is dominant for language processing with the right hemisphere being capable of performing less efficient auditory-verbal analysis. Results of a similar ANOVA procedure showed that all main effects and interactions were nonsignificant for the stutterers. From these data a bilateral model of neurolinguistic organization was derived for the stutterers where both hemispheres must participate simultaneously in the decoding process. This held true regardless of sex or severity of stuttering.
