Comparison of Semantic versus Syntactic Message Formulation: A Pilot Study
Patel, Rupal; Schooley, Katherine; Radhakrishnan, Rajiv
Assistive Technology Outcomes and Benefits, v3 n1 p96-109 Fall 2006
Two prototype voice output communication aids were implemented to compare methods of graphic symbol message formulation; one emulated current devices that require syntactical ordering of icons (Default) and the other used semantic frames (iconCHAT). Message constructions of eight typically developing children (7-10 years of age) using both prototypes were compared in terms of accuracy, speed, complexity, and preference. Although there were slight differences in speed, all participants formulated equally complex and grammatically accurate sentences using both prototypes. These findings demonstrate that semantic frame-based message formulation may be a viable alternative to conventional methods based on syntax. Future research to assess whether these findings extend to children who use AAC is warranted. Outcomes and benefits of semantic composition are particularly relevant for children with emerging grammatical skills since semantic schemas provide scaffolding for constructing complete utterances that may in turn foster increased self-confidence and improved perceptions of communicative competence.
