Manipulating establishing operations to promote initiations toward peers in children with autism.

This study examined the effects of manipulating establishing operations on the frequency of initiations of three children with autism toward peers with autism. The EO targeted was deprivation of preferred edibles, and the target initiation was a mand for the preferred snack. A reversal design was used to assess the effects of the EO conditions on frequency of initiations. Results indicated that when the EO was absent, no spontaneous initiations toward the peer occurred. Two participants required training sessions with an adult to transfer initiations toward peers. Once the EO had been established and was present, the participants initiated mands for the snack. Results are discussed in terms of implications for the use of establishing operations in language training for children with autism.
