Innovative solutions to support individuals with disabilities accessing public transportation: A case study.

Individuals with cognitive disabilities have challenges with personal navigation and wayfinding, especially when traveling on public transportation. The purpose of this case study is to describe the structure and implementation of the Personal Navigation for Individuals with Disabilities (PNID) education and training program, which is based on a socio-technical architecture for individuals with cognitive disabilities within a fixed-route public bus system. A case study methodology was used to describe preliminary findings of the skills, attributes, and experiences of three individuals with cognitive disabilities as it relates to transportation on fixed-route bus systems in a midsized urban setting. The three individuals completed five training activities: safety, public bus, smartphone, WayFinder App, and fixed-route bus system. The case study provided a preliminary mixed-methods overview of training travelers with cognitive disabilities to use the WayFinder system while accessing fixed-route public bus system. The insights and strategies identified through the case study demonstrate the potential opportunities for development, implementation, and sustainability of the PNID program in other midsized urban settings. The PNID program (i.e. AT service delivery process), in combination with the WayFinder system (i.e. assistive technology), has the potential to meet the unique needs of individuals with cognitive disabilities when accessing public transportation.

Examining core vocabulary with language development for early symbolic communicators.

PURPOSE: Core vocabulary lists are frequently used to select vocabulary for early symbolic communicators who require augmentative and alternative communication (AAC). The current study extended existing work by investigating how core vocabulary lists overlap and diverge from typical language development. METHOD: We investigated when the words on seven core vocabulary lists emerge in typical language development, the composition of the lists based on their parts of speech, and how the composition of the words on the lists compare to the MacArthur Bates Communication Development Inventories (CDI). RESULT: On average, the words on the seven core vocabulary lists appear after the second year of life in children with typical spoken language development (25, 27, 37, 45, 47, 50, and 66 months). Verbs were the most prevalent part of speech in all but one of the core vocabulary lists. Core vocabulary words made up only a small percentage of words on the CDI. CONCLUSION: The words on the core vocabulary lists do not emerge until later points in typical lexical development. Focussing on core words when working with early symbolic communicators who require AAC may lead to limited and variable lexicons with wide gaps.
