Community-based instruction with profoundly mentally retarded persons: client and public responsiveness.

Five adults with profound intellectual disability went to real stores. Staff used least-to-most prompts to teach them to touch the right item when asked. If they got it right, they got a small snack or toy right away.

Sessions happened during normal shopping trips. Prompts started with a gentle point and moved to hand-over-hand if needed. The team tracked correct touches across different stores and staff.

All five clients learned to pick the correct object when asked. They kept doing it in new stores and with new workers. No one started naming the items out loud.

Shoppers and store staff liked the program. They smiled, made room, and sometimes clapped.

Bonvillian et al. (1981) and Skrtic et al. (1982) also taught profoundly retarded clients new skills through staff in everyday places. Those studies aimed at expressive signing; this one aimed at receptive labels. Together they show staff can teach both understanding and expression outside the classroom.

Abdi et al. (2023) got big receptive gains in minimally verbal preschoolers with a 16-session package. Their kids also had autism and were much younger. The 1988 study shows even adults with profound ID can grow receptive language when teaching happens in the store itself.

Lord et al. (1986) used the same prompt-and-fade method for recess play and got strong maintenance. The matching pattern hints that prompting plus fading works across very different skills.

You can teach receptive labels without a classroom. Take clients to the real place, prompt from least to most, and deliver reinforcers on the spot. Expect generalization across stores and staff, but plan extra steps if you want spoken words. Community members will likely support you, so ask managers for permission and dive in.
