Variables influencing perceptions of the communicative competence of an adult augmentative and alternative communication system user
Abstract
The effects of aided message length, partner reauditorization, and observer background on perceptions of the communicative competence of an adult augmentative and alternative communication (AAC) system user were examined. Two groups of subjects participated: naive adults with minimal exposure to nonspeaking persons, and speech-language pathologists currently working with AAC users. Four scripted videotaped conversational conditions involving an AAC user and a normally speaking partner were employed to manipulate aided message length and partner reauditorization. A balanced incomplete block design was used. Following each viewing, subjects completed a questionnaire designed to assess the communicative competence of the AAC user. Results indicated a significant interaction effect involving subject group and aided message length. The speech-language pathologists were affected by aidedmessage length. Furthermore, significant differences between subject groups were found inspecific conditions. Future research directions are discussed.
