A lack of functional communication negatively impacts a student's academic and social-emotional success. Schools are in the position to create systems and protocols that would allow students to be taught a method to communicate functionally. This dissertation project sought to answer the question: How can early childhood students with no verbal…

For children with autism or intellectual and developmental disabilities who also have complex communication needs, communication is a necessary skill set to increase independence and quality of life. Understanding the how, where, and communication style being taught is important for identifying deficits in the field as well as which interventions…

Purpose: Providing telepractice services to young children with autism who use augmentative and alternative communication (AAC) can present many challenges for speech-language pathologists (SLPs). At the same time, telepractice can be a valuable service delivery option with unique benefits, such as improving partnerships with families, integrating…

This study compared a picture exchange (PE) system and an iPad®-based speech generating device (SGD) when teaching requesting skills to preschoolers with developmental disabilities and limited functional speech. A multiple baseline design with counterbalancing the order of two instruction conditions across participants was applied to compare the…

Purpose: Social interaction poses many challenges for adolescents with autism spectrum disorder (ASD) and complex communication needs. The purpose of this study was to investigate the impact of video visual scene displays (video VSDs) on communication during interactions between adolescents with ASD and peer partners. Method: This study used an…

The purpose of this study was to investigate the effects of an augmentative and alternative communication (AAC) app with transition to literacy (T2L) software features (i.e., dynamic text and speech output upon selection of a graphic symbol within the grid display) on the acquisition of 12 personally relevant single words for individuals with…

This paper provides an overview of five review studies that analyzed 92 single subject studies on the effectiveness of major augmentative and alternative communication (AAC) systems for individuals with developmental disabilities including autism. This paper offers recommendations useful for AAC decision-making points. Research on the…

Smartwatches may provide a natural, portable, and unobtrusive strategy by which to support directive-following for individuals with autism spectrum disorders (ASD). A mentor can send visual supports (e.g., photographs, videos, text) "just-in-time" (JIT) to a learner's smartwatch. This may reduce the need for extraneous face-to-face…

The purpose of this study was to examine the effects of special educators' delivery of training that included an initial training session and follow-up coaching on paraprofessional implementation of an evidence-based practice for students with autism spectrum disorder (ASD). Three special educators each trained a paraprofessional in their…

Peer networks are a promising intervention for increasing social interactions between students with severe disabilities and their peers. However, this approach has not been well studied with high school students who have complex communication needs and use augmentative and alternative communication (AAC). In this study, we used a multiple probe…

Autism is a disability characterized by impaired social interactions, limited verbal and nonverbal communication, and restricted and repetitive patterns of behavior. Children with autism may not make friends, spend more time alone than with others, and may not develop empathy or other forms of social reciprocity. This study explores the effect of…

Purpose. This quantitative study examined parent perceptions regarding augmentative and alternative communication (AAC) interventions for their children with autism to determine if, according to parent perceptions, a relationship existed between AAC and functional communication. Those faced with cognitive and developmental delays like autism face…

Students with complex communication needs require well-designed supports to communicate effectively in school settings. Although paraprofessionals are often charged with supporting these students, they are rarely trained in how to promote communication, and there is limited research on how they might be trained. In this study, we used a multiple…

Students with autism spectrum disorder (ASD) have challenges with communication, social interactions, and behavior, which can limit their functioning in school settings. They need to have functional communication skills to access the curriculum and have their needs met across all social environments. Special education teachers often experience…

This paper provides an overview of the literature investigating the functional relationship between the use of the Picture Exchange Communication System (PECS) and maladaptive behavior (i.e., aggression, tantrums) in individuals with autism spectrum disorders (ASD). Digital searches were conducted to identify single subject design studies…
