This study evaluated the acquisition of use of an iPhone 4 by adults with moderate intellectual disability to take and send video captions of their location when lost in the community. A multiple probe across participants design was used to evaluate the effectiveness of the intervention which used video modeling, picture prompts, and instructor prompts. Results indicate that the three participants learned to follow a sequence of steps for operating the iPhone 4 with video captioning and to use the skill across three unfamiliar community settings.
