Further evaluation of component skills that facilitate the emergence of intraverbal tacts

Five autistic children joined the study. Each child first learned element tacts. They learned to name single features like color or shape. Next they practiced intraverbal categorization. They answered questions like Name three animals. When both skills were solid the team watched for intraverbal tacts. These are answers that need both a question and a pictured item. Example: the child sees a dog and hears What does it bark? The correct reply is Dog. No one taught that last step directly.

Every child produced intraverbal tacts without extra teaching. Once element tacts and categorization were strong the mixed response appeared. The study says these two pieces are enough. You may not need full intraverbal drills.

Vascelli et al. (2024) got the same outcome starting from fluent tact naming. They used speed drills instead of element tacts plus categorization. Both paths lead to emergent intraverbals.

Hewett et al. (2024) looks like a contradiction at first. Tact-only teaching helped only one of four kids. The rest needed multiple-exemplar instruction. The difference is Kate’s team skipped the categorization step. Adding that step in Pantano’s package may close the gap.

ILee et al. (2022) showed listener training can also spark intraverbals. They taught children to pick the card that answers When do you eat? Later the kids could say Breakfast without being taught. Pantano starts from the expressive side, IK from the listener side. Both routes work.

You can save hours by splitting the task. Teach feature naming and category naming first. Then check if intraverbal tacts pop out. If they do you can skip long intraverbal programs. If they don’t add multiple-exemplar work as Kate et al. suggest. This two-step check keeps therapy lean and kid-friendly.
