Brief report: effects of tact training on emergent intraverbal vocal responses in adolescents with autism.

May et al. (2013) · Journal of autism and developmental disorders 2013
★ The Verdict

Tact training alone can create untrained intraverbal answers in adolescents with autism—probe for these emergent responses before adding separate intraverbal programs.

✓ Read this if BCBAs teaching verbal behavior to autistic teens in clinic or school.
✗ Skip if Teams focused only on motor or self-care goals.

01Research in Context

01

What this study did

Three teens with autism joined a short tact program.

They learned to name cartoon characters and each character’s favorite food.

No one ever asked them questions like “What does Bugs like to eat?”

02

What they found

After the tact lessons, all three teens answered the new questions without extra teaching.

The intraverbal replies popped up even though the team had only trained tacts.

03

How this fits with other research

Dixon et al. (2017) saw the same spark in younger kids.

They used PEAK-E match-to-sample and got emergent intraverbals too.

Tullis et al. (2022) also found new verbal answers, but they used instructive feedback during DTT.

Together the papers show multiple roads to the same place: untrained verbal relations.

Kisamore et al. (2016) looks like a contrast.

They had to run prompt delay plus extra fixes to teach intraverbals directly.

The difference is method.

Kisamore taught tough multiply-controlled questions.

Tassé et al. (2013) taught simple tacts and let emergence do the rest.

04

Why it matters

Before you write a separate intraverbal program, probe for emergent responses.

Run a quick cold-sheet after tact training.

If the learner already answers, you just saved hours of drill.

03Original abstract

The present study evaluated the emergence of intraverbal responses following tact training with three adolescents diagnosed with autism spectrum disorders. Participants were taught to tact the name of a cartoon character (e.g., "What is the name of this monster?" ["Simon"]) and that character's preferred food (e.g., "What food does this monster eat?" ["Chips"]). Following tact training, test probes revealed the emergence of untrained vocal intraverbals. Specifically, in the absence of pictures, participants stated the name of the character when given the food preference (e.g., "Which monster eats chips?"), and stated the food when given the character name (e.g., "What food does Simon eat?"). The findings are discussed with reference to the growing literature on verbal behavior and derived relational responding.
