Oral sensory and motor behaviors of children with /s/ or /r/ misarticulations.
Measurements of lingual two-point discrimination, oral form discrimination, and alternate motion rate of the tongue were made in 15 children who had normal articulation, 15 children who misarticulated /s/, and 15 children who misarticulated /r/. The two groups of children with misarticulations were found to differ from each other as well as from normal children on various aspects of oral sensation and motor abilities. These findings are interpreted as evidence for the existence of different bases for the misarticulations of the two disordered groups.
