An evaluation of prompting procedures in error correction for children with autism

Four children with autism learned new matching tasks. When they made errors, the teacher used two kinds of prompts to fix them.

One prompt was echoic: the teacher said the right word and the child repeated it. The other prompt was picture: the teacher showed a photo of the correct answer. The team flipped the two prompts across days to see which led to faster mastery.

Every child reached mastery first with picture prompts. On average they needed 30 % fewer trials than with echoic prompts.

Errors also dropped sooner. Once pictures were in, kids rarely made the same mistake twice.

Wachob et al. (2015) saw no boost when they simply added pictures to instructions. The difference: they tested a mixed group of kids, most with general delays, not autism only. Yuan’s tighter autism sample shows pictures do help when the task is error-correction, not just listening.

Belisle et al. (2020) used most-to-least prompting to teach children to read feelings from bandages or tears. Their social-tact results extend Yuan’s idea: prompts that show something visual speed up learning for kids with ASD.

Vie et al. (2017) used the same alternating-treatments design. They had kids name pictures aloud and later recall more. Both studies say the same thing: make the child look at and tact a picture, and the skill sticks faster.

Next time a child errs during matching or listener programs, swap the echoic step for a quick photo or icon. One extra second to flash the picture can save minutes of repetition and cut escape behavior. Track trials to mastery for a week; you should see the same drop Yuan found.
