Bimanual hand writing in right-handed and left-handed stutterers and nonstutterers.
Right-handed stutterers performed more poorly with their nondominant hand when writing digits and letters bimanually, and also made more nondominant hand mirror reversals than did nonstutterers. Left-handed stutterers and nonstutterers differed only in the incidence of mirror reversals with the nondominant hand. The results support the hypothesis that disorganization in the integration of left- and right-hemisphere inhibitory and excitatory processes may be an integral component of stuttering.
