Mands sometimes are taught using the question "What do you want?" as a supplement to the required features of the mand relation: an establishing operation and a related consequence. Although verbal prompts have been used during mand training, they also may result in undesirable stimulus control. However, no direct empirical evidence exists to support this concern. The purpose of the present study was to compare mand training with and without supplemental questions on acquisition rate and maintenance when those questions were no longer presented. The 2 training conditions did not differ substantially in their outcomes for 2 children with autism.
