Stuttering and oral stereognosis.
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.
