Abstract: 

The research was designed to test a hypothesis that relates stuttering to an anomaly in the functioning of the corpus callosum. The approach involved an analysis of concurrent hand and foot motor performance. Stutterers and non-stutterers showed more interference with ipsilateral than contralateral limb pairs, a finding contrary to the hypothesis. This finding is, however, consistent with the "Functional Cerebral Space" model of neural organization. Of special significance was evidence of group differences in the effect of left versus right foot tapping on hand performance. Non-stutterers showed more interference when tapping with the left foot, while stutterers showed the reverse pattern. It was argued that this reflects a dissociation between structural and attentional asymmetries in the brain of stutterers.
