A technology-aided stimulus choice program for two adults with multiple disabilities: Choice responses and mood

This study was aimed at replicating and extending early research on technology-aided stimulus choice with two adults with multiple disabilities. The technology-aided program involved (a) a computer-aided system presenting the participants samples of different environmental stimuli and (b) a microswitch device allowing them to choose among those samples and to access the related stimuli for preset periods of time. The system also allowed the participants opportunities to request the continuation/repetition of any stimulus. The program was successful in promoting the participants’ selection of preferred stimuli and their requests for continuation/repetition of those stimuli. Data also showed that the intervention sessions largely improved the participants’ mood (i.e., increased their indices of happiness). Theoretical and practical relevance of the findings were discussed.

► A technology-aided stimulus choice program was used with two persons with multiple disabilities. ► The participants succeeded in selecting preferred stimuli and requesting their continuation/repetition. ► Participants had large increases in indices of happiness during the choice sessions.
