Vocal stereotypy in individuals with autism spectrum disorders: a review of behavioral interventions.
ABA can turn down vocal stereotypy, but you still have to experiment to find the right tactic for each child.
01Research in Context
What this study did
The authors read every paper they could find on ABA ways to quiet vocal stereotypy in autism. They grouped the tactics into two buckets: things you do before the behavior and things you do after.
No new kids were tested. The team just mapped the field and flagged where evidence was thin.
What they found
Many tricks—like response interruption, redirection, or giving a favorite toy—can cut the repetitive sounds. Yet no study shows which trick to pick first for a given child.
In short: lots of tools, no clear recipe.
How this fits with other research
Sloman et al. (2024) extends this review. They tried one of the reviewed tactics—response interruption and redirection (RIRD)—and found low-preference tasks beat high-preference tasks in four kids.
Two vest studies seem to clash. Hodgetts et al. (2011) and Watkins et al. (2014) both report weighted or snug vests do nothing for stereotypy. That looks like a contradiction, but the review never praised vests; it only praised behavioral antecedents. Vests are sensory gear, not behavior-analytic tools, so the findings actually live in different worlds.
Rodgers et al. (2021) zoom out further. Their big meta-analysis shows broad early ABA can raise IQ and daily skills, placing stereotypy tactics inside a larger success story.
Why it matters
You now know RIRD is worth a shot, especially with low-preference work tasks. You also know vests are a dead end. Because no ranking exists, start with the least intrusive tactic, take data, and switch if nothing changes after two weeks.

03Original abstract
Vocal stereotypy is a common problem behavior in individuals with autism spectrum disorders that may interfere considerably with learning and social inclusion. To assist clinicians in treating the behavior and to guide researchers in identifying gaps in the research literature, the authors provide an overview of research on vocal stereotypy in individuals with autism spectrum disorders. Specifically, the authors review the research literature on behavioral interventions to reduce engagement in vocal stereotypy with an emphasis on the applicability of the procedures in the natural environment and discuss the clinical implications and limitations of research conducted to date. Researchers have shown that several antecedent-based and consequence-based interventions may be effective at reducing vocal stereotypy. However, the review suggests that more research is needed to assist clinicians in initially selecting interventions most likely to produce desirable changes in vocal stereotypy and collateral behavior in specific circumstances.
