Children who lack functional spoken language are candidates for augmentative and alternative communication (AAC). Aided AAC and naturalistic interventions offer the potential to extend the communication functions demonstrated by children with autism spectrum disorder (ASD) who are nonspeaking. Related intervention research, however, has been…

This study evaluated the use of an interrupted chain procedure to establish spontaneous mands (i.e., requests) in three preschool aged children with a diagnosis of autism spectrum disorder. All three participants attended a university based preschool center, which used the methodology of Applied Behavior Analysis. Additionally, all three…

Approximately 30% of individuals with autism have complex communication needs (CCN). These individuals are unable to use vocal speech as their primary form of language and typically require support across several areas of communication such as comprehension, pragmatics, phonology, semantics, and syntax (Ganz et al., 2022; Reichle, 2019).…

Purpose: Speech-language pathologists (SLPs) use prompting hierarchies to facilitate learning and monitor treatment progress. When working with people who use augmentative and alternative communication (AAC), SLPs typically use physical assistance to prompt motor learning. However, there is currently no standardization regarding the number of…

For individuals with autism spectrum disorder (ASD) who have limited to no vocal speech abilities, mobile augmentative and alternative communication (AAC) technology provides opportunities for communication with those around them. Interventionists can incorporate evidence-based practices into AAC instruction to heighten the efficacy of its…

This series of three studies identified an experimental research gap in the field of deafblindness. Study 1, a descriptive study, identified types of articles published, and research designs used, in 37 peer-reviewed special education journals. A total of 4,854 articles published from 2012 through 2017 were examined to determine types of articles…

The present study evaluated a systematic instructional package including the system of least prompts (SLP) to teach differentiation and selection of tangible symbols to continue activities for two children with complex support needs and deafblindness (DB). A multiple probe design across three symbols was used to evaluate the intervention package…

Purpose: This study aimed to explore the feasibility of a telepractice communication partner intervention for children who use augmentative and alternative communication (AAC) and their parents. Method: Five children (aged 3;4-12;9 [years;months]) with severe expressive communication impairments who use AAC and their parents enrolled in a…

Special education teachers are often responsible for training their staff how to support children with autism spectrum disorder in their classrooms. In addition to academic and behavioral interventions, paraeducators also need to be prepared to support students with complex communication needs. This study was designed to investigate the effects of…

This practice report presents the study of a young girl named Laura, with ASD and visual impairment who was taught basic requesting skills through an adapted augmentative and alternative communication (AAC) system, which is an evidence-based practice for addressing communication with children who have ASD but has limited research efficacy for…

Purpose: Children with autism spectrum disorder (ASD) and complex communication needs are increasingly taught to use tablet-based speech-generating devices (SGDs). An important issue in designing such interventions is the selection of an appropriate format for displaying vocabulary. The purpose of this study was to determine (a) whether young…

Identifying potentially effective practices for improving outcomes for individuals with autism spectrum disorder (ASD) is a complex process. In this article, we respond to recent reviews of evidence-based practices for individuals with ASD. We identify possible problems and make suggestions in relation to identifying well-specified practices,…

The purpose of this study was to evaluate the effects of different speech-generating device displays and vocabulary organizations on the acquisition of multi-step requesting responses in children with autism spectrum disorder (ASD). Four young children with ASD were taught to use an iPad® application to make requests using both a taxonomically…

This study aimed to teach individuals with autism spectrum disorder (ASD) and limited vocal speech to emit target vocalizations while using a speech-generating device (SGD). Of the 4 participants, 3 began emitting vocal word approximations with SGD responses after vocal instructional methods (delays, differential reinforcement, prompting) were…

This article provides clinicians and educators a useful conceptualization of general instructional strategies often used to promote the performance of requests in children with developmental disabilities, and which can be applied in interventions that utilize augmentative and alternative communication. A case study illustrates the specialized…
