Communicative competence as perceived by adults with severe speech impairments associated with cerebral palsy.

The effects of aided message length (single-word vs. phrase-generated messages) and partner feedback (presence vs. absence of expanded message repetitions) on perceptions of the communicative competence of an adult augmentative and alternative communication (AAC) system user were examined. Subjects consisted of 12 nonambulatory adults with severe speech impairments associated with cerebral palsy. Four scripted videotaped conversational conditions involving the AAC system user and a typically speaking partner were employed to manipulate the two independent variables. A balanced incomplete block design was used. Following each viewing, subjects completed a questionnaire designed to assess the communicative competence of the AAC system user. Results indicated that neither independent variable had an impact on the subjects' ratings of communicative competence. Findings are compared with those from an earlier investigation, and clinical implications are discussed.

Variables influencing perceptions of the communicative competence of an adult augmentative and alternative communication system user.

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 aided message length. Furthermore, significant differences between subject groups were found in specific conditions. Future research directions are discussed.

Comparison of nonspeaking and speaking mentally retarded adults' clarification strategies.

Interactions between speaking and nonspeaking persons using communication boards have frequently been found to be plagued by conversational breakdowns. Previous investigators, drawing upon anecdotal evidence, have painted a scenario in which the nonspeaker confuses the listener by transmitting an ambiguous message, the listener then requests clarification, the nonspeaker fails to clarify, and the discourse is abruptly terminated. The present study examined 5 speaking and 5 nonspeaking moderately-severely mentally retarded subjects' responses to their listeners' requests for clarification. An informal conversational format was used to evoke 40 possible repairs from each subject. Few differences were noted with respect to the ways in which speaking and nonspeaking subjects revised or failed to revise their messages. Both groups were highly responsive to their listeners' requests for clarification; subjects rarely ignored or changed the topic of discourse following these listener requests. However, unlike previous reports of nonretarded normally developing language-disordered children operating at comparable mental and linguistic levels, these speaking and nonspeaking subjects generally repeated their ambiguous messages rather than revising them. The results indicated the need to develop techniques for teaching speaking and nonspeaking retarded adults alternate methods of repairing conversational breakdowns.
