Oral vibrotactile sensation: an evaluation of children with normal and defective articulation.
Lingual vibrotactile thresholds (LVTs) were determined at 125, 250, and 500 Hz for 30 children with defective articulation and 30 children with normal articulation. Secondly, attempts to predict the phonemic and distinctive feature errors from LVTs for defective articulating children is presented. Children with normal articulation show significantly lower (better) LVTs at each frequency than do children with defective articulation. Significant relationships were not found between LVTs and phonemic scores or distinctive feature errors.
