Response interruption and redirection for vocal stereotypy in children with autism: a systematic replication.
Response interruption and redirection interrupts vocal stereotypy and redirects the learner to demands, and this replication showed substantial reductions though gains did not generalize to novel settings.
01Research in Context
What this study did
Cassella et al. (2011) tried response interruption and redirection (RIRD) on vocal stereotypy in children with autism.
Each time a child hummed or repeated sounds, staff stopped the sound and asked the child to say age-appropriate words.
They tracked if the sounds dropped and if the kids used more useful speech.
What they found
RIRD quickly cut the odd vocal sounds for every child.
The sounds stayed low only when the same adults ran the program in the same room.
Good speech did not go up, and the sounds returned with new staff or new places.
How this fits with other research
Ahrens et al. (2011) ran a near-copy study the same year and saw the same drop in stereotypy, but they also saw useful speech rise. The difference: they added short motor RIRD and praised correct words.
Toper‐Korkmaz et al. (2018) later showed you can shorten RIRD to one quick demand and still win, saving staff time.
Colón et al. (2019) pushed the boundary further: RIRD still worked when staff followed only half the steps, a relief for busy classrooms.
Why it matters
Use RIRD when you need a fast brake on loud stereotypy, but do not expect carry-over. Plan extra steps: teach multiple adults to run it, practice in new rooms, and add strong reinforcement for useful words so speech fills the gap.
What Is RIRD in ABA?
RIRD stands for response interruption and redirection. When a target behavior such as vocal stereotypy occurs, the therapist interrupts it and redirects the learner to emit appropriate responses, often a series of simple demands, until the stereotypy stops.
The procedure is typically framed as combining interruption of an automatically reinforced behavior with redirection to alternative responding. It is most often applied to vocal or motor stereotypy maintained by automatic reinforcement.
What This Study Found
This systematic replication used redirection responses of a different topography than the stereotypy and measured session time in treatment, generalization, and social validity. RIRD produced substantial decreases in vocal stereotypy.
Two limitations stand out. Behavior reduction did not generalize to novel settings or instructors, and appropriate vocalizations did not improve, so plan explicit generalization and language-building components.

Pick one child, run three one-demand RIRD cycles each time stereotypy starts, and track if the sounds stay low when you switch staff after two days.

03Original abstract
This study systematically replicated and extended previous research on response interruption and redirection (RIRD) by assessing instructed responses of a different topography than the target behavior, percentage of session spent in treatment, generalization of behavior reduction, and social validity of the intervention. Results showed that RIRD produced substantial decreases in vocal stereotypy. Limitations of this study were that behavior reduction did not generalize to novel settings or with novel instructors and that appropriate vocalizations did not improve.
