May 17, 2010 · We evaluated differential reinforcement of alternative behavior (DRA) plus prompting to increase peer-directed mands for preferred items using a picture exchange communication system (PECS). Two nonvocal individuals with autism participated.

Nov 21, 2022 · Using Picture Exchange Communication System (PECS). There are many different types of mands. Mands can be requests for: Information using “wh questions”: what, where, who, which, how, and why. Mands are among …

Chambers and Rehfeldt (2003) compared the acquisition of mands via PECS and signed language with four adults with intellectual disabilities. The authors simultaneously taught PECS and signed mands for the same four items (M&M, puzzle, string beads, and carrots) for each participant using identical graduated prompting strategies; however, the ...

Three common forms of alternative communication include sign language, the Picture Exchange Communication System (PECS), and aided Augmentative and Alternative Communication (AAC) devices. Beyond these difficult choices, the side effects of language delays, such as self-injurious behavior (SIB), must also be addressed.

The mand repertoire is essential for early language learners and is therefore of clinical importance. First, mands increase the probability of obtaining access to specific items, activities, actions, information, etc., when access to those stimuli is …

We evaluated the effects of systematic prompting plus reinforcement on listeners’ independent responses to peer mands and on speakers’ peer-directed mands using the picture exchange communication system (PECS) in two studies.

Oct 30, 2018 · The results indicated that PECS effectively increased vocal mands and decreased aggressive behavior maintained by access to preferred items in all three settings. The results also suggested that vocal mands were potentially controlled by pictures in the PECS book.

The purpose of this study was to investigate the effects of the Picture Exchange Communication System (PECS) on vocal mands and aggressive behavior displayed by a child with autism in China. One 4-year-old boy with autism participated in this study.

The current investigation evaluated the effects of extinction and prompts on training and generalization of peer-directed mands for preferred items using a picture exchange communication system with 2 children diagnosed with autism.

Generalization of mand skills consistent with mastery of Phase 3 was assessed for mands acquired using PECS across both settings and communicative partners. Generalization probes occurred prior to training and immediately following mastery of five mands.
