The Effects of a Procedure to Decrease Motor Stereotypy on Social Interactions in a Child With Autism Spectrum Disorder

Tereshko et al. (2021) · Behavior Analysis in Practice 2021
★ The Verdict

Pair differential reinforcement with a kid-run counter to cut flapping and raise social bids at the same time.

✓ Read this if BCBAs whose clients with autism hand-flap, rock, or spin items during social activities.
✗ Skip if Clinicians only targeting vocal stereotypy or working exclusively with adults.

01Research in Context

01

What this study did

Tereshko et al. (2021) worked with one child with autism who flapped and rocked a lot.

They mixed two tricks: first, praise and small prizes when the child played or talked without flapping. Second, they taught the child to count his own flaps and give himself tokens for quiet hands.

Sessions happened in different rooms and with different people to see if the fix would travel.

02

What they found

Motor flapping dropped sharply as soon as the package started.

At the same time the child began starting games, answering questions, and looking at adults far more often.

The gains stayed high even when staff stepped back and let the child run his own counter.

03

How this fits with other research

Chandler et al. (1992) did the first self-management test for social skills in autism. Their kids also talked more and acted out less after learning to score their own behavior. Tereshko adds differential reinforcement to the mix and shows the same social lift while also cutting stereotypy.

Crossman et al. (2018) used backward chaining plus differential reinforcement to raise toy play and saw stereotypy fall for two of three children. The new study swaps chaining for self-management and targets social bids instead of play, yet the stereotypy drop looks just as large.

Segal-Gavish et al. (2016) and Burrows et al. (2018) trimmed repetitive grooming in autism-model mice with stem cells or a drug. Those biologic cuts were small; the behavioral package here produced a large, quick change in a real child—no lab mouse required.

04

Why it matters

You can run the same one-two punch in an afternoon: set a timer, deliver praise or tokens for quiet hands plus any social move, and hand the counter to the learner. The child in the study kept the wins without adults hovering, giving you a low-effort route to slash stereotypy while building the social responses that matter for friendships and classroom success.

03Original abstract

Repetitive and stereotypic motor movements and vocal behavior are among the diagnostic characteristics of autism spectrum disorder (American Psychiatric Association, 2013, Diagnostic and Statistical Manual of Mental Disorders [5th ed.]. Washington, DC: Author). Motor stereotypy can interfere with the acquisition and demonstration of many adaptive skills and may socially stigmatize individuals, limiting the development and maintenance of peer relationships. The current study evaluated the effects of a differential reinforcement procedure used to establish discriminative stimulus control over the rate of motor stereotypy. In the second experimental phase, the child was taught a multistep self-management program using the differential reinforcement procedure. The data indicate that the procedure was effective in decreasing the rate of motor stereotypy across all evaluated settings for an increased duration. Although motor stereotypy was not completely eliminated by the procedure, a large reduction in rate was observed, as well as a large increase in the initiation of and response to social interactions. The findings are discussed in terms of social validity and the establishment and transfer of stimulus control.
