Video-Based Visual Scene Displays May Boost Peer Communication in Minimally Speaking Autistic Children
New Study Explores Communication Support for Autistic Children
Minimally speaking autistic children often face challenges in engaging in back-and-forth social communication with peers. A recent study investigated whether augmentative and alternative communication (AAC) interventions using video-based visual scene displays (VSDs) could improve symbolic communication directed toward peers during play.
Study Design and Participants
The research employed a single-case, multiple-probe design across dyads, involving 15 autistic children with minimal speech and 15 age-matched neurotypical peers. These participants were grouped into three cohorts of five pairs each, allowing for staggered introduction of the intervention. Initial baseline assessments used static printed VSDs to evaluate communication before introducing the video-based intervention.
Intervention Details
The intervention featured video-based VSD AAC tools that combined dynamic visual supports with speech-generating communication devices. This approach aimed to provide contextualized and interactive communication opportunities embedded within reciprocal play sessions.
Key Findings
Results showed immediate and consistent increases in peer-directed symbolic communication among autistic children following the introduction of the video-based VSD AAC intervention. Visual and statistical analyses demonstrated significant improvements with minimal overlap between baseline and intervention phases. Additionally, follow-up assessments indicated that these communication gains were maintained after the intervention ended.
Implications for Families and Educators
These findings suggest that incorporating video-based VSD AAC within naturalistic, play-based interactions may enhance social participation and meaningful communication for minimally speaking autistic children. Embedding AAC tools in peer play contexts could create more opportunities for reciprocal social engagement.
Limitations and Considerations
While the study provides promising evidence, it involved a relatively small sample and focused on specific dyads in controlled play settings. Further research is needed to explore long-term effects and generalizability across diverse environments and populations.
