Review of the Literature


It is surprising that there exist relatively few studies of the movement of the mandible or lower jaw with regard to misarticulation while the activity of the tongue, on the contrary, has received much attention. The purpose of this experiment is to investigate the extent of mandibular movement in the production of nonsense syllables and sentences as spoken by children with dyslalic and normal speech.
