This study aimed to evaluate the impact of a speech-generating device (SGD) application on manding skills in Chinese children with autism spectrum disorder (ASD). Given the communication challenges faced by many individuals with ASD, alternative methods for expressing needs are crucial. The SGD utilized speech synthesis technology to provide…

This comprehensive review reports on methodological quality of 162 single-case studies on augmentative and alternative communication interventions for communication and challenging behavior in individuals diagnosed with autism or intellectual disabilities and with complex communication needs. Following review for inclusion criteria, documents were…

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…

In the present study, we aimed to make an evaluation, conduct comprehensive descriptive analyses, and calculate the effect sizes of studies which compare AAC applications designed according to single-subject research designs and conducted for individuals with ASD. Within the scope of this aim, 21 studies meeting the inclusion criteria were…

There is a lack of research on effective interventions to improve the early numeracy skills of children with severe disabilities---autism spectrum disorder, developmental disability, and intellectual disability---and complex communication needs. While preliminary research suggests the Early Numeracy curriculum is effective for teaching children…

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 contribute to the secondary-tier evidence of the three-tier video modeling intervention model (3TVM), using a group-based generic video, and to explore a new form of augmentative and alternative communication (AAC) intervention using a Chinese-language interface for teaching children with developmental disabilities. A multiple…

Percentages of correct responses to decoding probes (i.e., phoneme identification, blending phonemes to identify words, blending phonemes to identify pictures) were measured across three participants with moderate intellectual disability or autism in elementary school. Time delay and system of least prompts were used in conjunction with an AAC…

The Picture Exchange Communication System (PECS) is an augmentative and alternative communication (AAC) program used to teach functional requesting and commenting skills to people with disabilities (Bondy & Frost, 1993; Frost & Bondy, 2002). In this study, tangible symbols were added to PECS in teaching requesting to four students (ages 7-14) with…

A structured intervention package including direct, scaffolded, instructional lessons was implemented using an error correction learning system and a picture book-based phonological and phonemic awareness activity for four participants with complex communication needs, ranging from 12 to 15 years, in a junior high school setting. Although…
