The Picture Exchange Communication System (PECS) is an augmentative and alternative communication (AAC) program used to teach functional requesting and commenting skills to people with disabilities (Bondy & Frost, 1993; Frost & Bondy, 2002). In this study, tangible symbols were added to PECS in teaching requesting to four students (ages 7-14) with…

Shared stories have been shown to help increase emerging literacy skills in students with significant intellectual disabilities. One important literacy skill is the development of listening comprehension. In this study, least-to-most prompt system was used to promote listening comprehension during shared stories for two students with significant…

The Picture Exchange Communication System (PECS) is an augmentative and alternative communication program (Frost & Bondy, 2002). Although PECS has been effectively used to teach functional requesting skills for children with autism, mental retardation, visual impairment, and physical disabilities (e.g., Anderson, Moore, & Bourne, 2007; Chambers &…

Positive reinforcement was used to effectively treat aggressive and noncompliant behavior of two visually impaired, multiply handicapped male students (an 18-year-old and an 11-year-old). In one case positive effects of treating aggressive behaviors generalized to a reduction in self injurious behaviors. (DB)

Positive reinforcement (food) presented both regularly and variably was effectively used to reduce self-stimulatory behavior in a 12-year-old profoundly retarded visually impaired male over a 2-month period. The improved behavior was maintained after the summer break and into the new school year. (DB)

In a single-subject design with replication across Ss, teacher prompts were used in an attempt to increase the rate of social behavior of three severely and profoundly retarded adolescents who were legally blind. Training took place in the classroom on successive school days with the teacher prompting each S to engage in positive social…
