Peer social interactions are particularly important for young children's social-emotional competence, language development, and social inclusion (Guralnick, Hammond, Connor, & Neville, 2006; Joseph, Strain, Olszewski, & Goldstein, 2016). Adequate social communication assists children in forming and sustaining these social relationships. Although there is a clear link between social interactions and positive outcomes, interaction rates of children with disabilities are generally lower than those of typically developing children (Honig & McCarron, 1988). Moreover, children who use augmentative and alternative communication (AAC) devices are at a particularly greater risk for social isolation (Clarke & Kirton, 2003). High quality inclusive early childhood environments provide an avenue for these important social interactions between typically developing children and children with disabilities (Strain & Bovey, 2011; Wolery & Hemmeter, 2011); however, placing children in inclusive environments is not sufficient for increasing positive interactions (Odom, Buysse, & Soukakou, 2011). In inclusive environments, typically developing children tend to interact with their typically developing classmates without adult intervention or interference (Guralnick, Connor, Hammond, Gottman, & Kinnish, 1996). Thus, to improve rates of interactions between children with and without disabilities, adults may need to provide prompting and reinforcement. Stay-play-talk (SPT) is a peer-mediated intervention designed to increase the social interactions of children with and without disabilities in inclusive preschool classrooms (Goldstein, Kaczmarek, Pennington, & Shafer, 1992). Typically developing peers are taught specific strategies to stay, play, and talk with their peers with disabilities, and teachers prompt and reinforce the peers for engaging in SPT behaviors in free play or other settings or activities throughout the
