ABA Fundamentals

Comparison of two procedures for teaching dictated-word/symbol relations to learners with autism.

★ The Verdict

A three-second pause before showing picture choices speeds up word-picture learning for kids with autism.

✓ Read this if BCBAs who use computer-based matching programs to teach language to learners with autism.
✗ Skip if Clinicians working only on vocal behavior or tabletop tasks without match-to-sample components.

01Research in Context

01

What this study did

Two boys with autism learned to match pictures to spoken words on a computer.

The team compared two ways to teach this skill. One way waited three seconds before showing the picture choices. The other way used exclusion trials where the wrong choice was obviously wrong.

They switched the teaching style back and forth to see which one worked faster.

02

What they found

The three-second delay won almost every time.

Kids learned the word-picture links faster when the screen paused before showing the choices.

03

How this fits with other research

Tenneij et al. (2009) later tested the same delay idea with adults who have intellectual disabilities. They flipped the order and showed the choices five seconds before the sample. Accuracy still jumped, so the delay trick works across ages and diagnoses.

LeFrancois et al. (1993) did something similar ten years earlier. They used delayed matching to teach spelling to students with mental retardation. Their success foreshadowed that a simple pause can build new relations without extra drills.

Irvin et al. (1998) tweaked a different part of matching: they added a third choice. That small change also helped a preschooler with autism hit 95 % correct. Together these papers show that tiny layout or timing changes can give big gains in conditional-discrimination tasks.

04

Why it matters

If you run computerized match-to-sample lessons, insert a brief pause before the comparison pictures appear. Three seconds is plenty. This cheap tweak can cut teaching time for learners with autism and may work for other populations too. Try it next session and track how many trials it takes to reach mastery—you might finish the program days earlier.

03Original abstract

The efficacy of exclusion and delayed-cue procedures for establishing novel dictated-word/symbol relations with 2 boys with autism was compared using computerized match-to-sample procedures. Acquisition of the relations under the two training conditions was compared via an alternating treatments design. The delayed-cue procedure was more efficacious than the exclusion procedure in four of five comparisons across participants.
