Stuttering and Oral Stereognosis

Abstract

Two experiments were conducted to investigate oral stereognostic performance of stutterers. In Exp. I, stutterers and controls responded “same”—“different” to two oral forms placed successively on their tongues. In Exp. II, stutterers and controls underwent two procedures. For half the items, the task was the same as in Exp. I; for the other half, subjects were presented a single form and visually identified that form from among others on a placard. In both experiments, stutterers made significantly more oral stereognostic errors than did their matched controls.
