Effects of video-assisted training on employment-related social skills of adults with severe mental retardation.

Researchers taught four adults with severe intellectual disability how to ask for help, materials, and feedback at work. They used two steps: first the adults watched short videos of the correct social skill, then they practiced the same skill in their actual job setting with a coach.

The team tracked each worker during real shifts. They counted how often the adult used the new social skill without being told. The study ran in a real sheltered workshop, not a classroom.

Video watching alone did not help. The adults could say the right words in tests, but they never used them on the job. Once the coach added on-the-floor rehearsal, every worker started asking for help, tools, and feedback during real work tasks.

The new skills stuck. The adults kept using the requests even after the coach stepped back. Skills moved from practice to the paycheck setting.

Capalbo et al. (2022) saw the same pattern with kid soccer players. Video modeling plus video feedback beat plain video. The 1992 job study and the 2022 sports study line up: modeling alone is weak until you add feedback or rehearsal.

Martinez et al. (2024) also tested video modeling plus feedback in youth soccer. They found either video feedback alone or the combo worked well. This slightly softens the 1992 claim that rehearsal is a must-have, but the workers had far more severe ID than the soccer kids, so the extra rehearsal step still looks vital for adults with significant delays.

Savaldi-Harussi et al. (2025) compared video displays to flashcards for word learning. Video helped younger students with moderate ID but not older students with severe ID. Again, the more severe the disability, the more the learner seems to need something extra—like the in-vivo rehearsal used here.

If you run job training for adults with ID, do not stop at a training room video. Build in real-time rehearsal on the factory floor, in the kitchen, or wherever the paycheck task happens. Have the client actually ask the real supervisor for the real item while you stand by to prompt and praise. Drop that extra step and the skill will probably stay locked in the classroom.
