Abstract:
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 replicated and evaluated an extension of this procedure that was directed at facilitating intraverbal tacts when a child learns the component skills but continues to fail to produce intraverbal tacts. The extension consisted of procedures 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 after undergoing the extension procedures. These results are discussed in the context of a conceptual analysis of intraverbal tacts and the potential role of joint control.
