Teaching key use to persons with severe disabilities in congregate living settings.

Researchers taught adults with severe intellectual disability how to find and use a key.

The adults lived in group homes. Staff used hand-over-hand help, then less help, then praise.

They tracked each adult across days to see if the skill stuck.

Most adults learned to open the lock when staff gave prompts.

Once staff stopped helping, only some adults kept the skill.

Prompts worked for teaching, but fading them out was the hard part.

Whitehead et al. (1975) saw the same thing in a classroom. Kids with ID needed a spoken cue to copy a peer’s good sitting. Prompts worked, yet they had to stay in place.

Shih et al. (2011) took the opposite road. They let adults turn on music by stepping on a Wii board. The adults kept moving because the music was its own reward. No extra prompts were needed.

Together the papers show: if the reward is built in, you may not need to fade prompts. If the reward is staff praise, plan a slow fade or the skill can drop.

When you teach a daily living skill, pick the right reward first. If the reward is just your “good job,” write a prompt-fading plan from day one. Try moving from hand-over-hand to a light tap, then to a gesture, then to a picture cue. Check weekly without any cue. If performance falls, re-introduce the last cue level and fade again. This keeps the skill alive after you walk away.
