Stimulus-Stimulus-Pairing to Reduce Stereotypies in Three Children with Autism during Movie Watching.

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.
