Assisting persons with multiple disabilities to move through simple occupational activities with automatic prompting.

Lancioni et al. (2008) worked with four adults who had both vision and hearing loss. Each adult had to finish three-step jobs like putting folders into a box. The team set up two machines: one blew a puff of air on the hand and one played a short voice cue. The machines fired by themselves when the person stopped moving for too long.

The study used a multiple-baseline design across participants. Prompts were automatic; no staff had to stand nearby.

All four adults learned to move through the jobs after the automatic prompts. When the team later doubled the task list from three to six steps, the adults still kept working without extra help. Skills stayed high after the machines were removed.

Coleman-Martin et al. (2004) also used prompting to teach new skills, but they needed a staff member to wait and deliver each cue. E et al. swapped the human for a sensor and still got good results. The new method removes the need for a partner.

Ozen et al. (2022) taught preschoolers to fasten snaps and buttons with two live prompting styles. Both worked, yet an adult had to give every cue. E et al. shows that machines can take over once learners are older and tasks are vocational.

Kobylarz et al. (2020) taught vocational tasks to adults with developmental disabilities too, but they used backward chaining with staff guidance. E et al. proves you can replace that guidance with automatic air or voice prompts and still see success.

If you serve adults with dual sensory loss, you can set up cheap sensors or voice players to keep them moving through work tasks. You free up staff time while the learner gains independence. Try adding an automatic prompt the next time someone stalls mid-sequence; fade it once the flow feels natural.
