Students with autism and related developmental disabilities who do not speak are often taught to use some type of augmentative and alternative communication (AAC) system, such as a voice output communication aid (VOCA). One problem with such devices is that the person may be unable to communicate when the device is not readily accessible. We first taught three nonverbal students with autism to use a VOCA to request access to preferred items. Following this initial acquisition phase, however, none of the students would locate their VOCA when it was not within reach. A least-to-most prompting procedure was implemented to teach the students to locate their AAC device. The effectiveness of this procedure for teaching VOCA location skills was evaluated in a delayed multiple-baseline across subjects design. The results showed that the intervention was effective in teaching the students to locate their AAC device when they needed it to request access to preferred objects. Teaching VOCA location skills may be a useful and necessary component in AAC interventions for some people with developmental disabilities. © 2004 Elsevier Ltd. All rights reserved.
