Stutterers' vocal reaction times to unilaterally presented high and low frequency verbs

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