Adapted Picture Exchange Communication System using tangible symbols for young learners with significant multiple disabilities

Abstract

Practitioners need validated strategies for teaching children with significant multiple disabilities (e.g., cognitive, motor, and sensory disability) to use tangible symbols for expressive communication. This single-case experimental design study replicated the positive effect of an adapted protocol for teaching Phase 1 of the Picture Exchange Communication System (PECS) using tangible symbols and extended it to a younger group (4–7 years old) of learners with multiple disabilities. It also tested the effect of an adapted protocol for Phase 2 of PECS to incorporate use of a single switch speech-generating device to gain the attention of an adult communication partner. Two of three students who reached mastery in Phase 1 also reached mastery in Phase 2 and may have generalized requesting behavior from the interventionist (i.e., researchers) to their classroom teacher. Results add to the growing evidence base that shows that the adapted PECS Phase 1 procedures are a promising practice for learners with multiple disabilities, including sensory impairment, and provide preliminary evidence for a more efficient and effective approach to adapting PECS Phase 2 than previously studied for this group of learners. Directions for future research and recommendations for practice are provided.
