The effects of information and augmentative communication technique on attitudes toward nonspeaking individuals.

This study investigated the effects of printed factual information and three augmentative communication techniques on attitudes of nondisabled individuals toward nonspeaking persons with physical disabilities. Employing a 3 (augmentative communication techniques) x 2 (presence/absence of information) factorial design, subjects viewed a videotape depicting a nonspeaking adult having a conversation with a normal-speaking individual. Subjects in Condition 1 viewed a tape depicting the nonspeaking individual using unaided communication techniques; Condition 2 subjects viewed the individual using an alphabet board; subjects in Condition 3 viewed the individual using a computer-based voice output communication aid (VOCA). A scale assessing attitudes toward nonspeaking persons, the Attitudes Toward Nonspeaking Persons Scale (ATNP), was developed and validated for purposes of this study and was employed as the dependent measure. Results revealed that subjects expressed more favorable attitudes when provided with the additional information concerning the nonspeaking individual. Attitude favorability also increased with the sophistication of the augmentative communication technique.
