Abstract (AI)
Abstract There are few procedures to teach non‐vocal children vocal mands. This study evaluated the effects of prompting, fading, and differential reinforcement on eye contact, pointing, vocal approximations, independent requests and immature mands in three children with Autism Spectrum Disorders who in baseline emitted almost no independent vocal mands. This procedure resulted in a large and socially valid increase in independent vocal mands, other appropriate responses and near elimination of immature mands. Copyright © 2010 John Wiley & Sons, Ltd.
Key Findings
1
A combined procedure of prompting, fading, and differential reinforcement produced a large increase in independent vocal mands in three non‑vocal preschool children with ASD.
2
Participants emitted almost no independent vocal mands in baseline but showed socially valid gains after the intervention.
3
The intervention also increased other appropriate responses, including eye contact, pointing, and vocal approximations.
4
The procedure led to near elimination of immature mands that were present at baseline.
