The role of increased exposure to transfer-of-stimulus-control procedures on the acquisition of intraverbal behavior.

Tavassoli et al. (2012) worked with preschoolers who had no known disabilities. The kids took turns with echoic prompts, tact prompts, or no prompts before learning new intraverbal questions.

Each child got a quick warm-up with one prompt type. Right after, the teacher asked new questions like "What do you wear on your feet?" The team counted how many trials each child needed to answer without help.

Children learned the new answers faster when the warm-up prompt matched the style used during teaching. If echoic practice came last, echoic prompts in teaching worked best. The same rule held for tact prompts.

This boost showed up in every child. The effect was clear after only a few minutes of exposure.

Kay et al. (2020) ran the same kind of study with children with autism. They saw the same speed-up, proving the trick works across diagnoses.

Galtress et al. (2012) also compared prompting styles for intraverbals, but they looked at echoic plus error correction versus a different method called cues-pause-point. Both papers agree that echoic prompts can be powerful, yet Tiffany focused on which style teaches best, while T et al. show that recent use alone makes any style work faster.

Hewett et al. (2024) found that some children with autism need extra multiple-exemplar instruction after tact training to gain intraverbals. T et al.'s shortcut—brief prompt exposure—could be used first to cut teaching time before adding more intense methods.

You can shrink teaching time by simply priming the prompt type you plan to use. Spend two minutes on echoic practice if you will use echoic prompts in the next task. Rotate prompt styles across the day so each stays fresh and efficient. This quick step costs nothing and speeds learning for both neurotypical kids and children with autism.
