    Abstract:
    An important issue in teaching verbal behavior to persons with severe handicaps is the transfer of stimulus control from tact (e.g., naming) to mand (e.g., requesting) relationships. Previous research has shown that topographies taught as tacts frequently fail to appear as mands unless transfer between these two response classes is explicitly programmed. Procedures promoting this transfer would provide a necessary instructional tool. Transfer from tact to mand contingencies was investigated in two adults with severe mental retardation. Correct pointing responses to line drawing symbols depicting the utensils required to access previously requested food (beverage) items were assessed prior to and following tact intervention. Mands for two of three utensils emerged following tact intervention. The results suggest transfer from tact variables to the conditioned establishing operation may be facilitated by the prior development of a minimal mand repertoire.
