laterality theory

Refers to the theory that a shift in handedness or confused cerebral dominance is a factor in the cause or in the maintenance of stuttering. According to this theory, the use of the non-preferred hand in written and other skilled activities contributes to a cerebral instability affecting speech control in such a way as to generate stuttering. Laterality theory refers to insufficiently established dominance of one cerebral hemisphere over another.
