This review evaluated the effects of augmentative and alternative communication (AAC) on speech development in children with autism spectrum disorders (ASD); replicated, updated, and extended the systematic review by Schlosser and Wendt (American Journal of Speech-Language Pathology 17:212-230, 2008). Twenty-five single case design articles and…

The effectiveness of using Augmentative and Alternative Communication (AAC) with individuals with Autism spectrum disorder (ASD) is well documented in descriptive reviews and meta-analytic investigations published in international journals in the last decade. Most of these analyses include researches conducted in North-American or European…

Augmentative and Alternative Communication (AAC) is a core component of special education for many children with learning disabilities and/or autism who have minimal or no speech. Much literature focuses on implementation of AAC in the classroom or therapy setting, but less is known about how AAC is used in the family home. Few studies are…

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…

The present study evaluated the effects of online training on educators' knowledge and use of system of least prompts (SLP) to support the communication of individuals with autism who use augmentative and alternative communication (AAC). A pre/posttest group design with switching replications was utilized. Three dependent variables: (a) knowledge…

The extant literature on facilitated communication suggests facilitator control rather than independent communication. We used a novel assessment to evaluate a participant's correct identification of words produced during facilitated communication sessions. The participant was unable to recognize common words that she was being facilitated to…

Children with autism spectrum disorder (ASD) sometimes display an inability for information sharing through functional verbal communication. This may interfere with professional oral care. These children tend to process visual information more efficiently than auditory information. Picture schedules can briefly suffice as visual cues serving a…

Children with autism spectrum disorder (ASD) who have limited speech are often taught to communicate using a speech-generating device (SGD). We evaluated procedures for teaching a mand for information (i.e., "Where" is [item]?) using an interrupted behavior chain procedure. In Experiment 1, all participants (3 children with ASD who…

Purpose: This study reports a secondary analysis of the nature of communicative functions and modalities used in initiations and responses of minimally verbal preschoolers with severe autism spectrum disorder (ASD) from a previously published study (Thiemann-Bourque, Feldmiller, Hoffman, & Johner, 2018). This analysis focused on the final…

This study provides an example of using single case experimental design to guide data-driven, low-inference interventions for an individual using customized displays on a speech-generating device and can serve as an example for interventionists who need to compare intervention strategies to identify approaches that are most appropriate for a…

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…

In this paper, we examine the barriers to, and possibilities of, recognizing individuals labelled intellectually disabled as producers and contributors to knowledge about their experiences. Through engaging perspectives within the fields of philosophy of education and disability studies, we examine contrasting research about the use of facilitated…

Purpose: Many aided augmentative and alternative communication (AAC) systems require the use of an external display that is represented via a visual modality. It is critical to evaluate and understand visual-perceptual processing in individuals with disabilities who could benefit from AAC. One way to evaluate how individuals process visual…

The students with nonverbal autism are challenged in communicating their needs which is fundamental in the everyday life of a person. Augmentative and Alternative Communication (AAC) aids children with a speech impediment in expressing necessities. However, the Philippines might be one of the most numerous smartphone users in the world but it…

The present study evaluated the efficacy of a set of procedures for bringing tact extensions of abstract tactile properties under stimulus control. Two participants with disabilities who communicated via a picture-based communication system received reinforcement for tacts of tactile properties of four wet/dry and four hard/soft stimuli. Test…
