Abstract:
There are many children with autism spectrum disorder who are nonverbal and can’t communicate their wants and needs to other individuals. The Picture Exchange Communication System (PECS) is used for individuals who have no, or limited speech and provides an opportunity for augmentative /alternative communication. PECS is an effective way for an individual who is nonverbal to initiate requests using a binder, velcro strips, and single laminated symbolic cards. A survey was used to determine if the procedures that were found effective in the literature were used by the participants and if so, how effective these procedures were rated to be by them. The literature revealed a variety of effective procedures including PECS used to increase communication of children with autism spectrum disorder. These procedures included the use of point-of-view modeling (Rodrigues et al. 2020), technology (Hill et al. 2014), and systematic prompting (Doherty et al. 2018). The results of the study showed that the intervention packages including PECS used by most participants were least to most prompting, differential reinforcement, and vocal requests; used by 94% of participants, systematic prompting and reinforcement by 75%, and phases I-IV of PECS plus reinforcement by 69%.
