A comparison of two teaching procedures to establish generalized intraverbal-tacting in children with autism.

Previous research has investigated generalized intraverbal-tacting by teaching children with autism to respond using autoclitic frames. The present study compared the effectiveness and efficiency of a Frame and a No Frame procedure across counterbalanced stimulus sets with 4 children with autism. In the Frame condition, children were taught to respond using autoclitic frames (e.g., "Shape square," "Number two," "Color green," "It's mummy," "S/he is drinking") corresponding to the verbal antecedent ("What shape?", "What number?", "What color?", "Who is it?", "What is s/he doing?"). In the No Frame condition, intraverbal-tacting was established without the autoclitic frame. Irrespective of stimuli employed, 2 children acquired intraverbal-tacting only in the Frame condition. The other 2 children acquired intraverbal-tacting in both conditions, with the Frame procedure requiring fewer teaching trials for 1 child and producing greater generalization for the other. Implications for clinical practice and the role of additive intraverbal stimulus control of autoclitic frames are discussed.
