Stimulus-Stimulus-Pairing to Reduce Stereotypies in Three Children with Autism during Movie Watching.
Stimulus-stimulus pairing quietly cuts stereotypy and lifts appropriate movie watching for young autistic kids.
01Research in Context
What this study did
Three autistic children watched short movies. Each child rocked, flapped, or tapped throughout.
The team paired the movie sound with a tiny treat. No treat came when stereotypy started. This is stimulus-stimulus pairing.
An A-B-A design showed the change: baseline, pairing, then pairing removed, then pairing back.
What they found
Stereotypy dropped when pairing was on. Appropriate sitting and watching rose.
When pairing stopped, stereotypy returned. When pairing came back, stereotypy fell again.
How this fits with other research
Hawkes et al. (1974) first showed the same see-saw: stop self-stimulation and play jumps up. Esposito repeats the pattern with a softer tool—pairing instead of outright suppression.
Falligant et al. (2020) also cut motor stereotypy during leisure, but they used response interruption plus timed access. Both studies win, yet pairing needs no blocking, so hands stay free.
Ding et al. (2017) used matched sensory NCR and DRO. They saw mixed spill-over to non-targeted stereotypy. Esposito only looked at the paired form; we still don’t know if other stereotypy drifts down too.
Why it matters
You can run pairing right in the living room or clinic movie corner. No blocking, no extra tokens—just sound linked to a bite of food. Try it during iPad time next Monday; count stereotypy for five minutes before and after you start the pairing. If it drops, you have a low-effort option that keeps the activity fun and the hands quiet.

03Original abstract
Autism spectrum disorders represent a challenge for professionals, who must include in their individualized educational interventions goals for core symptoms (social–communication and stereotypies/restricted interests) and comorbidities. The narrowness of interests and the high frequency of repetitive behaviors in children with autism often constitute an obstacle for learning and the quality of life, and for their caregivers as well. In the scientific literature, behavioral interventions based on both aversive and, less commonly, positive procedures have been implemented to reduce the frequency of stereotypies. The following study was carried out with the intention of replicating a Stimulus-Stimulus Pairing procedure applied by Nuzzolo-Gomez, Leonard, Ortiz, Rivera and Greer (2002) in order to reduce stereotypies in children. This procedure was applied to three children diagnosed with autism aged five, almost six and seven years, in order to reduce stereotypies when children watched movies. An A-B-A experimental design with three subjects was used for this research. The results showed a decrease in stereotypies in favor of appropriate behaviors.
