Visual identity matching and auditory-visual matching: a procedural note.
Drop in a third comparison picture to turn visual identity matching failures into 95% accuracy for preschoolers with autism.
01Research in Context
What this study did
A preschooler with autism could match sounds to pictures but kept failing when asked to match picture to picture. The team added a third picture to the usual two-choice task. They ran short sessions until the child hit 95% correct.
The study is tiny—one child—but the jump from 50% to 95% happened in one afternoon.
What they found
Adding one extra comparison picture fixed the error pattern right away. Visual identity matching climbed to 95% and stayed there.
The child still passed auditory-visual trials, so the boost was specific to the visual-visual task.
How this fits with other research
Farber et al. (2016) extends this idea. They used a five-step sorting game before matching and also hit 95% accuracy with five preschoolers. Sorting first gives extra scaffolding; three choices give a lighter nudge.
Tenneij et al. (2009) looks like a contradiction. They cut errors in half by showing the choices five seconds before the sample. The trick seems opposite—delay versus extra stimuli—but both changes make the sample stand out. One slows the task; one enriches the array.
LeFrancois et al. (1993) did similar identity matching years earlier with adults who had intellectual disability. Their success supports the core method; the 1998 tweak simply adapts it for very young kids with autism.
Why it matters
If a learner passes auditory-visual matching yet keeps failing visual-visual, do not jump to prompt-heavy programs. First try sliding in a third picture. It costs nothing, takes minutes, and may give you instant mastery. Use it as a quick diagnostic tweak before you redesign the whole lesson plan.

03Original abstract
After preliminary computerized training on visual-visual identity matching, a 5-year-old boy with autism (Sam) was given visual-visual and auditory-visual matching-to-sample tests with new stimuli. He did well in matching dictated name samples to 20 pictures, 26 printed upper case letters, and 9 single-digit numbers. In matching the visual stimuli (pictures, letters, or numbers) to themselves, however, he did not perform well. We then increased the number of picture comparisons per trial from two to three. In tests after this three-comparison training, Sam correctly matched on 95% of the original 20-stimulus, four-comparison, identity-matching test trials. He went on to demonstrate accurate identity matching of the numbers, letters, and new pictures. In identity-matching tests on the table top, he performed poorly until the stimulus array was made to resemble the stimulus arrangement on the computer. These findings showed that seemingly small procedural changes can influence performance and demonstrated that successful auditory-visual matching does not guarantee proficiency in visual-visual identity matching.
