Stutterers' vocal reaction times to unilaterally presented high and low frequency verbs.
The current study investigated vocal reaction times of 11 stuttering participants to verbs with high and low frequencies of occurrence when these verbs were unilaterally visually presented. No significant main effects or interactions between stimuli and visual-half field were found. Reaction times were 16 msec. faster after right visual field presentations and the Pearson correlation coefficient between visual fields .71 (p=.02). These results were interpreted as suggesting that the left hemisphere was dominant for processing the current lexical items, findings which parallel those for normal speakers.
