ABA Fundamentals

A comparison of response interruption and redirection and competing items on vocal stereotypy and appropriate vocalizations

Shawler et al. (2020) · Journal of Applied Behavior Analysis 2020
★ The Verdict

RIRD beats toys for cutting vocal stereotypy and boosting real speech—if you use toys, choose ones that make sound.

01Research in Context

01

What this study did

Shawler and team worked with three kids who had autism and lots of vocal stereotypy.

They tested three things in the same room: response interruption and redirection (RIRD), sound-making toys, and quiet toys.

Each day they rotated which method they used and counted how much stereotypy and real speech happened.

02

What they found

RIRD cut vocal stereotypy the most and also made appropriate talking go up.

Sound-making toys helped more than quiet toys, but neither beat RIRD.

The kids kept these gains when the team checked weeks later.

03

How this fits with other research

This study lines up with Migan-Gandonou et al. (2020), who also used an alternating-treatments design to stop a repetitive behavior—rumination instead of vocal stereotypy.

Both papers show that brief, consistent consequences work better than just giving items to play with.

Wunderlich et al. (2017) and Cordeiro et al. (2022) used the same design to fine-tune teaching, proving the method is solid across very different goals.

Unlike the older Goldman et al. (1979) rumination study, Shawler skipped food satiation and still got strong results, showing the field has moved toward leaner, safer procedures.

04

Why it matters

If a child on your caseload hums or scripts all day, try RIRD first—interrupt the sound, then prompt a quick functional phrase like “I want car.” If you must use toys, pick ones that beep or play music; they cut stereotypy more than silent blocks or books.

03Original abstract

The current study compared the reductive effects of response interruption and redirection (RIRD) and competing items (including sound-producing and nonsound-producing toys) on the vocal stereotypy exhibited by two children diagnosed with Autism Spectrum Disorder. Sound-producing toys reduced vocal stereotypy relative to nonsound-producing toys and RIRD reduced stereotypy and increased rates of appropriate vocalizations to a greater extent than providing competing items. These findings replicate and extend previous literature suggesting that RIRD and sound-producing competing items are effective methods to treat vocal stereotypy.
