van der Meer, Larah; Sutherland, Dean; O'Reilly, Mark F.; Lancioni, Giulio E.; Sigafoos, Jeff – Research in Autism Spectrum Disorders, 2012
We compared acquisition of, and preference for, manual signing (MS), picture exchange (PE), and speech-generating devices (SGDs) in four children with autism spectrum disorders (ASD). Intervention was introduced across participants in a non-concurrent multiple-baseline design and acquisition of the three communication modes was compared in an…

Barnes, Clarissa S.; Dunning, Johnna L.; Rehfeldt, Ruth Anne – Research in Autism Spectrum Disorders, 2011
The picture exchange communication system (PECS) is a functional communication system frequently used with individuals diagnosed with autism spectrum disorders who experience severe language delays (Frost & Bondy, 2002). Few empirical investigations have evaluated strategies for training direct care staff how to effectively implement PECS with…

Ganz, Jennifer B.; Earles-Vollrath, Theresa L.; Mason, Rose A.; Rispoli, Mandy J.; Heath, Amy K.; Parker, Richard I. – Research in Autism Spectrum Disorders, 2011
Individuals with autism spectrum disorders (ASD) who cannot speak at all or not intelligibly are frequently taught to use aided augmentative and alternative communication (AAC). The majority of the research on the use of AAC with individuals with ASD has been single-case research studies. This investigation involved a meta-analysis of the…

Angermeier, Katie; Schlosser, Ralf W.; Luiselli, James K.; Harrington, Caroline; Carter, Beth – Research in Autism Spectrum Disorders, 2008
Research on graphic symbol learning suggests that symbols with a greater visual resemblance to their referents (greater iconicity) are more easily learned. The iconicity hypothesis has not yet been explored within the intervention protocol of the Picture Exchange Communication System (PECS). Within the PECS protocol, participants do not point to a…

The Impact of the Picture Exchange Communication System on Requesting and Speech Development in Preschoolers with Autism Spectrum Disorders and Similar Characteristics
Peer reviewed Peer reviewed
Direct linkDirect link
Ganz, Jennifer B.; Simpson, Richard L.; Corbin-Newsome, Jawanda – Research in Autism Spectrum Disorders, 2008
By definition children with autism spectrum disorders (ASD) experience difficulty understanding and using language. Accordingly, visual and picture-based strategies such as the Picture Exchange Communication System (PECS) show promise in ameliorating speech and language deficits. This study reports the results of a multiple baseline across…
