Acquisition of Mands, Tacts, and Intraverbals Through Sign Exposure in an Individual With Autism

By Amber L Valentino and M. Alice Shillingsburg


Many children with autism communicate through the use of alternative communication systems, such as sign language. Limited research has been conducted on the situations under which sign language will be acquired across verbal operants without direct teaching. The purpose of the current study was to evaluate exposure to sign language on the acquisition of signed mands, tacts, and intraverbals in a male child with autism. Results indicated fast acquisition of mands, tacts, and intraverbals without direct teaching. Results are discussed in the context of future research investigating exposure without direct teaching in individuals who communicate with alternative communication systems
