This study examined the use of verbal behavioral analysis strategies to elicit adult-preferred responses from students with autism aged 4 to 10 years who are beginning communicators, using an AAC app that allowed mirroring across devices. After a student initiated embodied communication to select a preferred item, the therapist used mand on the AAC device that resulted in the student using the correct symbol for the item. A second student repeated a message on his AAC device but since therapist set the device to a “one message delivered-one message heard” setting, the student was unable to engage in “electric echolalia”. In the final incident, the communication partner used a modeling prompt multiple times until it elicited a second pair part of imitation from the student.
