Enabling persons with intellectual or multiple disabilities to carry out personal care tasks (such as washing and dressing) independent of guidance from parents or staff members and without prolonged interruptions is often difficult, particularly with persons whose disabilities also include visual impairments. Attempts were recently made to curb the problem of dependency in personal care tasks with the use of assistive technology, which ensured a combination of verbal prompting and preferred stimuli that were automatically delivered on positive performance. The goal of the study presented here was to help three new participants with multiple disabilities acquire independent dressing through an upgraded version of the technology. This technology provided prompts only for the failure to respond and included auditory, visual, and vibratory stimuli as reinforcing events or prompts. The data, which largely support and extend those that were previously reported in this area, appear encouraging with regard to the possibility of using technological solutions to promote daily self-help skills.
