Top-Down Attentional Processing and Relational Density Evident in Word Search Performance of Children
Train tight word classes, then watch kids find those words first in a puzzle—proof the relations stuck.
01Research in Context
What this study did
Three children with autism played word-search puzzles. First they got relational training. Trainers taught them to group new words into tight or loose classes. Then the kids hunted for those words in a letter grid.
The team timed how fast each child found high-density words versus neutral ones. High-density words had many trained links. Neutral words had few links. The game showed if the training steered attention.
What they found
After training, every child spotted high-density words faster. They passed over neutral or low-density words more often. The trained links acted like magnets for their eyes.
No extra prompts were needed. The kids simply noticed the rich-word group first.
How this fits with other research
Lattal (2004) first showed that adults with autism beat typical adults on plain visual search. Belisle adds a twist: train links first, then search. The same population now shows a learning-driven bias, not just raw speed.
Barton et al. (2019) saw that children with autism stay stuck on perceptual choices even when you give comparisons. Belisle’s team proved you can push them into abstract relations with direct equivalence training. The earlier study described the hurdle; this one offers a hop-over.
Adams et al. (2021) found bright distractors hurt word recognition for toddlers with autism. Belisle’s kids, however, had no flashy pictures—just letters. The positive result here hints that reducing visual clutter lets the trained relations guide attention, turning last year’s negative into a practical tip.
Why it matters
You can use word-search games as a quick, cheap probe after equivalence lessons. If the child finds trained words faster, you know the class is solid. No extra tests, no toys. Just print a puzzle and watch where their eyes go.

03Original abstract
Relational frame theory and extensions (e.g., relational density theory; Belisle & Dixon, 2020a, 2020b) provides a behavioral model for top–down attentional processing, where attention is oriented in terms of arbitrarily applicable verbal relations through the transformation of stimulus function. Children’s games may provide a strategy for testing transformations of stimulus function when developing new language skills, such as when working with children with autism. Three children with autism underwent relational training to establish lean and dense arbitrary classes. Prior-to relational training, participants were more likely to locate familiar words over unfamiliar words within a word-search task. Following relational training, participants were more likely to locate words that participated in high-density relational classes over neutral or low-density relational classes. These results support the use of common games to supplement relational training with children with autism and provide evidence that top–down attentional processing may involve transformations of stimulus function and can be predicted and influenced through relational training to establish high-density relational classes.
