Teaching a Child with Autism to Mand for Answers to Questions Using a Speech-Generating Device.

The current study systematically replicates and extends the findings of Ingvarsson and Hollobaugh (2010) by teaching a boy with autism who used a speech-generating device to mand for answers to unknown questions. The effects of the intervention were evaluated via a multiple baseline across stimulus sets. The intervention resulted in acquisition of both the mand for information and intraverbal responses (i.e., correct answers to previously unknown questions). However, generalization of the mand for information was limited.
