Although the last decade has welcomed evidence that individuals with Rett syndrome (RTT) can communicate using alternative and augmentative communication (AAC), less is known about effective procedures for teaching various component skills required for expressive communication of individuals with complex communication needs. The purpose of the…

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…

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…

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…

Adolescents with autism spectrum disorder (ASD) often require support both for learning new skills and for communication. This study used a multiple baseline across activities design to evaluate the effect of videos with integrated visual scene displays (video VSDs), presented using a tablet-based app, on the percentage of steps completed…

The most researched and effective practice for instructing children with Autism Spectrum Disorder (ASD) is applied behavior analysis (ABA; Baer, Wolf, & Risley, 1968; Reichow, 2012; Smith & Eikeseth, 2011; Virués-Ortega, 2010). ABA is a scientific approach to systematic instruction, data collection, and data analysis based on observable…

Effective vocational instruction is an essential aspect of preparing students with intellectual and developmental disabilities (IDD) for the world of work. We systematically reviewed research on instructional methods used to teach employment skills to secondary students with IDD. We identified 56 studies involving 766 participants with IDD. Four…

This study evaluated the effects of a peer-delivered least prompts intervention and adapted read-alouds of a grade-level novel on correct listening comprehension responses for participants with moderate intellectual disability. Before the study began, participants were taught concepts for wh- words (i.e., who, what, why, when, and where), to…
