In these two studies, two children with multiple disabilities and minimal motor behavior were assessed to see if they could use chin movements to operate microswitches to obtain environmental stimulation. In Study I, we applied an adapted version of a recently introduced electronic microswitch [Lancioni, G. E., O'Reilly, M. F., Singh, N. N.,…

We compared two procedures (video prompting versus video modeling) for teaching six adults with developmental disabilities to set a table and put away groceries. Video prompting involved 10 separate video clips, each showing one step of the task analysis. Video modeling involved a single video showing all 10 steps from beginning to end. After…

Persons with multiple disabilities often have limited functioning of their lower limbs and tend to spend large amounts of time sitting in a wheelchair. Efforts to enable some of these persons (that is, those who are in better overall physical condition) to make some use of their legs may involve the use of support walkers. The risk may be even…

We assessed the effects of two computer systems used as microswitches for the vocal utterances of an adolescent and a young adult with multiple disabilities. The systems were to respond to three one-syllable utterances of the first participant and nine word-like utterances of the second participant by presenting favorite stimuli linked to those…

Favorite stimuli were automatically delivered contingent on the performance of steps by two persons (a boy and a woman) with multiple disabilities during their use of support walker devices. The study lasted about 4 months and was carried out according to a multiple baseline design across participants. Recording concerned the participants'…

Two students (ages 7 and 8) who were totally blind with profound motor impairments and mental retardation were provided with optic microswitches. The use of optic microswitches for simple hand responses, combined with the availability of pleasant stimuli for the responses, proved successful with both students. (Contains 9 references.) (CR)

The use of microswitches has been considered a crucial strategy to help individuals with extensive multiple disabilities overcome passivity and achieve control of environmental stimulation (Crawford & Schuster, 1993; Gutowski, 1996; Ko, McConachie, & Jolleff, 1998). In recent years, considerable efforts have been made to extend the evaluation of…

A study assessed whether a program involving simple hand-movement responses combined with optic microswitches and followed by preferred stimuli would be successful with two persons with multiple disabilities (ages 11 and 30). Data showed participants reached fairly high levels of responding during intervention and retained their achievement…
