G.8 · Fading stimulus and response prompts
Prompts help a learner get it right, but the real goal is getting them out of the picture. Let's sort out the fading procedures so you can tell time delay, most-to-least and stimulus fading apart in seconds.
Key takeaway
Prompt fading moves stimulus control from the prompt to the natural SD, so plan the fading before you start teaching. To name a procedure, look at what changes over time. If the amount of help drops across trials, it's most-to-least. If help increases within a trial only after no response, it's least-to-most. If the prompt stays the same but the wait before it grows, it's time delay. If the stimulus itself changes, it's stimulus fading or stimulus shape transformation.
