Jena McDaniel – Journal of Autism and Developmental Disorders, 2025
Multiple contemporary theories emphasize the quantity and quality of child vocalizations for promoting spoken language acquisition. Yet, empirical evidence for facilitating vocal development is strikingly lacking including for children with autism spectrum disorder (ASD) who have difficulty developing language. We evaluate use of contingent…

Reem Muharib; Virginia Walker; Walker Dunn – Journal of Autism and Developmental Disorders, 2024
The purpose of this review was to assess the effectiveness of tablet-based speech-generating devices (SGDs) in improving communication skills for individuals with autism spectrum disorder (ASD). A total of 31 single-case design intervention studies involving 84 individuals with ASD were reviewed and included in the analysis. We calculated Tau-U to…

Douglas, Sarah N.; Meadan, Hedda; Biggs, Elizabeth E.; Bagawan, Atikah; Terol, Adriana Kaori – Journal of Autism and Developmental Disorders, 2023
Family-centered capacity-building practices have been shown to benefit children and families. However, limited research explores these practices for children who use augmentative and alternative communication. This study explored an intervention to teach family members to implement an Aided Language Modeling (ALM) strategy across natural…

Rose, Veronica; Paynter, Jessica; Vivanti, Giacomo; Keen, Deb; Trembath, David – Journal of Autism and Developmental Disorders, 2020
Comprehensive interventions for children with autism spectrum disorder (ASD) often incorporate augmentative and alternative communication (AAC); however, variability in outcomes exists even among children who access similar intervention. This study investigated predictors of expressive language change for 48 children with ASD aged 31 to 67 months…

Xin, Joy F.; Leonard, Deborah A. – Journal of Autism and Developmental Disorders, 2015
The purpose of this study was to examine the effects of using an iPad to assist students with autism in learning communication skills. Three, 10 years old learners diagnosed with autism who present little or no functional speech, participated in the study. A multiple baseline design with AB phases across academic and social settings was used.…

Ganz, Jennifer B.; Earles-Vollrath, Theresa L.; Heath, Amy K.; Parker, Richard I.; Rispoli, Mandy J.; Duran, Jaime B. – Journal of Autism and Developmental Disorders, 2012
Many individuals with autism cannot speak or cannot speak intelligibly. A variety of aided augmentative and alternative communication (AAC) approaches have been investigated. Most of the research on these approaches has been single-case research, with small numbers of participants. The purpose of this investigation was to meta-analyze the single…

Carr, Deborah; Felce, Janet – Journal of Autism and Developmental Disorders, 2007
The study investigated the impact of mastery of the Picture Exchange Communication System (PECS) to Phase III, on the communications of children with autism. Children aged between 3 and 7 years, formed a PECS intervention group and a non-intervention control group. The intervention group received 15 h of PECS teaching over 5 weeks. Three 2-h…

Bomba, Cheryl; And Others – Journal of Autism and Developmental Disorders, 1996
Facilitated communication (FC) as an augmentative or alternative communication system was evaluated with 14 students having autism. At the end of 10 weeks of instruction, no participants were able to produce functional, typed communication, thereby failing to support the cause-effect relationship proposed by FC proponents. (DB)

Simon, Elliott W.; And Others – Journal of Autism and Developmental Disorders, 1996
This study of an adolescent with multiple disabilities, including moderate mental retardation, who was reported to engage in validated facilitated communication (FC) found he did not engage in validated FC; performance was equivalent whether food or nonfood reinforcers were used; and the Picture Exchange Communication System was a valid and…

Bebko, James M.; And Others – Journal of Autism and Developmental Disorders, 1996
Potential individual variations in the effectiveness of facilitated communication (FC) were examined with 20 students with autism and related disorders. Use of multiple methods (including auditory or visual input, simple point responses, and typing) provided no clear support for validity of FC over students' independent communication. Increased…
