Communication deficits in children with Autism Spectrum Disorder (ASD) can manifest in a myriad of lifelong social and educational challenges. Many children with ASD fail to learn vocal verbal behavior and may require intensive individualized intervention to learn early verbal operants. The current research aimed to evaluate the effects of a parent delivered stimulus-stimulus pairing (SSP) procedure on target vocalizations of two young children with ASD who did not present with vocal verbal behavior. Results indicated the intervention was successful in increasing the frequency of the target vocalizations for both participants. Social validity results indicated that parents were satisfied with the intervention and their own implementation of these procedures. These results are discussed in terms of their implications for parent delivered interventions.
