Rodriguez et al. (2022) discovered that teaching four component skills was sufficient to facilitate the emergence of intraverbal-tacts across four applications with three participants. Our study evaluated an extension of this procedure aimed at facilitating intraverbal-tacts when a child learns the component skills but continues to fail to produce intraverbal-tacts. The extension consisted of procedures that attempted to enhance the divergent control exerted by the auditory stimulus (i.e., the question) and the discriminability of joint control. Intraverbal-tacts emerged for all three participants. These results are discussed in the context of Michael et al.’s (2011) conceptual analyses of intraverbal-tacts and the potential role of joint control.
