A comparison of two methods of prompting in training discrimination of communication book pictures by autistic students.

Four autistic students learned to pick the correct picture from a communication book. The teacher tried two ways to help: delayed prompting and fading prompts.

In delayed prompting, the child got a few seconds to answer alone before any help. In fading, the teacher slowly removed extra cues like color or size.

Delayed prompting won. Every child reached the goal in fewer tries and made fewer mistakes. Most problem behavior popped up only during fading sessions.

MOORHEARSKELLEHER et al. (1964) first showed fading can teach visual tasks with almost zero errors. The new study flips that idea: for autistic learners, waiting beats fading.

Cohen (1975) also found that keeping prompts inside the picture itself works better than adding outside cues. Berkowitz (1990) adds a time twist: give the child a moment before any prompt.

Freeman et al. (2024) later paired fading with short audio scripts and saw social gains. Their success came with scripts, not with picture cues, so both papers can be true at once.

If you teach PECS or any picture system, try delayed prompting first. Let the child attempt alone for three to five seconds. You will likely see faster mastery and less frustration. Drop the old habit of slowly removing bright borders or big prompts; just pause and then help if needed.
