Use of self-operated auditory prompts by workers with moderate mental retardation to transition independently through vocational tasks.

Five workers with moderate intellectual disability packed and labeled items in two sheltered workshops.

Each worker carried a small tape player and headphones. They pressed play when they finished one step. A short voice clip told them what to do next.

The team compared single-word cues (“wipe”) with longer cues (“wipe the counter”). They also ran short staff-prompt sessions to check if the device really helped.

Every worker started moving to the next task on their own as soon as the voice prompt played. Staff prompts were rarely needed.

Single-word and longer cues worked equally well. The workers kept the skill when they switched to a second workshop with no extra teaching.

Bigby et al. (2009) and Spanoudis et al. (2011) swapped the tape player for a PDA that mixed audio, pictures, and video. The idea is the same—self-delivered cues—but the richer media helped students with autism finish cooking and task boxes.

Chang et al. (2011) went further, trading handheld devices for a Kinect camera. Workers used arm waves instead of button presses, keeping the hands free. The core goal—no staff prompts—stayed intact.

Diemer et al. (2023) replaced audio with short video clips on phones. Eight young adults learned laundry and check-in routines just as fast, showing the prompt type can change without hurting results.

You can give learners control of the cue. A twenty-year-old tape player, a PDA, or a new phone app all work if the learner triggers it. Pick the device the person likes, load the steps, and let them press play. Independence goes up and staff time drops.
