Two studies (Stoner et al 2006;Tincani et al 2006, Study 2) used an ABAB design, while one (Ganz and Simpson In several studies, a changing criterion was included, reflecting the PECS phase changes but it was secondary to the main design (Bock et al 2005;Chambers and Rehfeldt 2003;Cummings and Williams 2000;Rehfeldt and Root 2005;Stoner et al 2006;Tincani 2004;Tincani et al 2006;Yokoyama et al 2006).

The Picture Exchange Communication System (PECS) is a communication program that has become widely used, especially with children with autism. This paper reports the results of a review of the empirical literature on PECS. A descriptive review is provided of the 27 studies identified, which included randomized controlled trials (RCTs), other group designs and single subject studies. For 10 appropriate single subject designs the percentage of nonoverlapping data (PND) and percentage exceeding median (PEM) metrics were examined. While there are few RCTs, on balance, available research provides preliminary evidence that PECS is readily learned by most participants and provides a means of communication for individuals with little or no functional speech. Very limited data suggest some positive effect on both social-communicative and challenging behaviors, while effects on speech development remain unclear. Directions for future research are discussed including the priority need for further well-conducted RCTs.

“…Individuals who lack intelligible speech are often candidates for such augmentative and alternative communication systems as manual sign, which involves approximations of hand gestures used in American Sign Language, a complex visual-spatial language that is used by the deaf community in the United States and English-speaking parts of Canada (Nakamura, 1995), and the Picture Exchange Communication System (PECS) (Bondy & Frost, 1993, 1994, in which a picture of a desired item is exchanged with a caregiver for access to the item itself (see Chambers & Rehfeldt, 2003). Vocal mand training may be appropriate for individuals who possess minimal vocal repertoires with some speech that is intelligible to others.…”

Specifically, we evaluated whether a history of reinforced relational responding would give rise to untrained vocal requests for novel items. Participants were first taught to request preferred items using their category names. They were then taught conditional discriminations between pictures of preferred items that were categorically related. Finally, participants were tested for their abilities to request items that had not been originally presented during request training, using their category names. All participants demonstrated untrained requests, and for some participants, changes in the mand repertoire were accompanied by changes in the tact repertoire. Some participants also showed generalization of skills across settings.

“…PECS was also better generalized to other situations (Anderson, 2002). Better generalization was also found in the other comparative study by Chambers & Rehfeldt (2003). One interesting review that reports manual signing being used within the frame of positive behaviour support is written by Bopp, Brown & Mirenda (2004).…”
