The Effectiveness of the Picture Exchange Communication System with Nonspeaking Adults

Abstract

Picture Exchange Communication System (PECS) training was implemented with 5 nonspeaking adults with mental retardation who were not currently using any type of functional communication system. A modified ABAB, single-subject design was used to assess the effectiveness of PECS in enhancing the functional communication skills of these individuals. Three individuals progressed through 4 PECS training phases relatively quickly and developed functional skills that they were able to display in home and community settings. Two other individuals demonstrated limited progress, and the PECS training did not meaningfully alter their level of communicative competence. Implications for teaching functional communication skills to nonspeaking adults are discussed, and recommendations for future research are provided.

“…The present reported outcomes replicate and extend the use of PECS to increase communication (Flippin et al, 2010;Miller et al, 2006;Stoner et al, 2006).…”

A Review of the Efficacy of the Picture Exchange Communication System Intervention

“…Adkins and Axelrod (2001), Chambers and Rehfeldt (2003) and Tincani (2004) Yokoyama et al 2006) used a multiple baseline across participants, while two (Frea et al 2001;Kravits et al 2002) used a multiple baseline across settings, one (Marckel et al 2006) used a multiple baseline across descriptors taught, and one (Cummings and Williams 2000) used a multiple baseline across activities. 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). Comparative group designs were employed in five papers.…”

“…Sesuai juga dengan penelitian Stoner, et al (2006) bahwa PECS adalah salah satu tehnik yang dapat digunakan untuk meningkatkan kemampuan komunikasi fungsional dan memperluas temuan sebelumnya pada orang dewasa yang tidak memiliki sistem komunikasi fungsional.…”
