Adkins, T. & Axelrod, S. (2002). Topography‐versus selection‐based responding: Comparison of mand acquisition in each modality.

The Behavior Analyst Today, 2, 259‐266.
Abstract: This study examined the acquisition of a mand repertoire by one child with pervasive developmental disorder and ADHD. The subject was taught to request preferred items using American Sign Language (a topography based response form) and the Picture Exchange Communication System (a selection‐based form). There were four types of sessions: (1) training session for PECS, (2) training session for sign language, (3) test for generalization of the PECS words, and (4) test for generalization for the sign words.

Webb, T. (1999). Look who’s talking!

Special Children, April/May.
Abstract: The author who is a teacher at Avalon Special School, Street, Somerset, introduced PECS to a class of 6, 4/5 year old children, with severe communication difficulties, and of whom 5 have autistic spectrum disorders. Lee Mas...

Webb, T. (2000b). The talking goes on ‐The Picture Exchange Communication System.

Special Children, June/July 2000.
Abstract: This article reviews the progress of a group of children 19 months after being introduced to PECS which was reported in Special Children 1999. The group have progressed from using 3‐5 word sentences incorporating attributes to spontaneously requesting and commenting both with and without PECS. As speech developed the teacher continued to use PECS as a framework for teaching further communicative functions and a range of curriculum subjects. Lee Mas...

Travis, J. & Geiger, M. (2010). The effectiveness of the Picture Exchange Communication System (PECS) for children with autism spectrum disorder (ASD): A South African pilot study.

Child Language Teaching and Therapy, 26, 39‐59.
Abstract: This study investigated the effects of introducing the Picture Exchange Communication System (PECS) on the frequency of requesting and commenting and the length of verbal utterances of two children with autism spectrum disorder (ASD) who presented with some spoken language, but limited use of language in communicative exchanges. Lee Mas...

Tincani, M., Crozier, S. & Alazetta, L. (2006). The Picture Exchange Communication System: Effects on manding and speech development for school‐aged children with autism.

Education and Training in Developmental Disabilities, 41, 177–184.
Abstract: We examined the effects of the Picture Exchange Communication System (PECS; Frost & Bondy, 2002) on the manding (requesting) and speech development of school‐aged children with autism. In study 1, two participants, Damian and Bob, were taught PECS within a delayed multiple baseline design. Both participants demonstrated increased levels of manding after implementation of PECS. Lee Mas...

Stahmer, A. & Ingersoll, B., (2004). Inclusive programming for toddlers with autism spectrum disorders: Outcomes from the Children’s Toddler School.

Journal of Positive Behavior Interventions, 6, 67‐84.
Abstract: The passage of the Individuals with Disabilities Education Act of 1990 mandated the provision of interventions for young children with autism spectrum disorders (ASD) under the age of 3 years. Although Strain, McGee, and Kohler (2001) suggested that children with autism benefit from inclusive programming, inclusive early intervention programs are rare. Lee Mas...

Schreibman, L. & Stahmer, A. (2014). A randomized trial comparison of the effects of verbal and pictorial naturalistic communication strategies on spoken language for young children with autism.

Journal of Autism and Developmental Disorders, 44, 1244-1251.
Abstract: Presently there is no consensus on the specific behavioral treatment of choice for targeting language in young nonverbal children with autism. This randomized clinical trial compared the effectiveness of a verbally-based intervention, Pivotal Response Training (PRT) to a pictorially-based behavioral intervention, the Picture Exchange Communication System (PECS) on the acquisition of spoken language by young (2–4 years), nonverbal or minimally verbal (≤9 words) children with autism. Lee Mas...

Greenberg, A., Tomaino, M. & Charlop, M. (2013). Adapting the Picture Exchange Communication System to Elicit Vocalizations in Children with Autism

Journal of Developmental and Physical Disabilities, DOI 10.1007/s10882‐013‐9344‐2.
Abstract: Little is known about the relationship between PECS training and vocalizations in children with limited verbal abilities (e.g., children who are unable to verbally imitate simple phrases). Study 1 used a multiple baseline design across children to examine the vocalizations of four children with autism during and after PECS training. Lee Mas...

Ganz, J., Simpson, R. & Corbin‐Newsome, J. (2008). The impact of the Picture Exchange Communication System on requesting and speech development in preschoolers with autism spectrum disorders and similar characteristics.

Research in Autism Spectrum Disorders, 2, 157–169.
Abstract: 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. Lee Mas...
