Using the Teacher IRAP (T-IRAP) interactive computerized programme to teach complex flexible relational responding with children with diagnosed autism spectrum disorder
Computerized T-IRAP drills make autistic children respond faster, yet wider language gains remain modest without extra teaching.
01Research in Context
What this study did
Murphy and team built a kid-friendly computer game called T-IRAP.
The game teaches children with autism to match words and pictures in flexible ways.
Five children played T-IRAP on some days and did regular table-top teaching on other days.
The team timed how fast and how accurately each child answered.
What they found
Every child pressed the correct keys faster during T-IRAP than during table-top drills.
Accuracy improved only a little, and one child showed gains on a language test after mastering the hardest game level.
The other four children did not score higher on the test after the game.
How this fits with other research
Chastain et al. (2026) later used the same equivalence idea with teens.
They taught value-to-action phrases and saw strong emergent intraverbals, showing the concept can travel across ages.
Nickerson et al. (2015) also used an alternating-treatments design and found that spreading practice across days beat cramming.
Murphy’s study adds that a computer can deliver those spaced trials faster, but the leap to real-world language stays small.
Gavidia et al. (2022) saw mixed emergence when they used instructive feedback in discrete trials.
Their uneven results echo Murphy’s modest accuracy gains, hinting that derived responding often needs extra supports.
Why it matters
T-IRAP gives you a speedy way to build relational flexibility, but do not expect big language jumps right away.
Use the game as a warm-up or fluency booster, then probe for untaught relations in natural tasks.
If scores stay flat, add more exemplars or bridge to real objects and conversations.

03Original abstract
The research used an alternating-treatments design to compare relational responding for five children with diagnosed autism spectrum disorder (ASD) in two teaching conditions. Both conditions used applied behavior analysis; one was usual tabletop teaching (TT), and one was an interactive computerized teaching program, the Teacher–Implicit Relational Assessment Programme (T-IRAP; Kilroe, Murphy, Barnes-Holmes, & Barnes-Holmes, Behavioral Development Bulletin, 19(2), 60–80, 2014). Relational skills targeted were coordination (same/different), with nonarbitrary and arbitrary stimuli. Participants’ relational learning outcomes were compared in terms of speed of responding and accuracy (percentage correct) in T-IRAP and TT conditions. Results showed significantly increased speed for all five participants during T-IRAP teaching across all procedures; however, accuracy was only marginally increased during T-IRAP. Pre- and posttraining comparison of participant scores on the Peabody Picture Vocabulary Test, Fourth Edition (Dunn & Dunn, 2007), and the Kaufman Brief Intelligence Test (Kaufman & Kaufman, 1990) was conducted. An improvement in raw scores on both measures was evident for one participant who learned complex arbitrary relations; no changes were shown for participants who learned only basic nonarbitrary relations.
