Beginning with Orton's theory of cerebral dominance in 1928, studies using laterality measures, Wada tests, electroencephalography, bimanual tasks, dichotic and tachistoscopic paradigms, and interhemispheric tasks have been published supporting a neurological and/or hemispheric involvement in the cause and maintenance of stuttering (Arends, Povel, & Kolk, 1988; Blood, 1985; Fitzgerald, Cooke, & Greiner, 1984; Greiner, Fitzgerald, & Cooke, 1986; Jonas, 1981; Kamhi & McOsker, 1982; Naatanen, 1992; Webster, 2004).
