The purpose of this investigation was to compare the transparency of verbs across two graphic symbol sets (Picture Communication Symbols and SymbolStix) frequently used in augmentative and alternative communication (AAC). In order to determine which set represents verbs most transparently, both typically developing children and children with documented speech/language impairments, age 6 to 8 years, were given a forced-choice identification task for both symbol sets. The task required participants to identify their perception of the correct symbol for a named referent verb when given the choice between four symbols. Results indicated that participants were significantly more likely to choose the expected target of the SymbolStix set as opposed to the Picture Communication Symbol set. Findings of this investigation may have clinical implications for children who need picture/symbol boards or booklets to facilitate their communication. Directions for further investigation are discussed. McNair Scholar project. Faculty Advisor: Ann Ratcliff
