Augmentative and alternative communication is a compilation of methods and technology designed to supplement spoken communication for people with limited speech or language skills, including children with developmental and intellectual disabilities. The field of AAC has evolved rapidly within the last 10 years, due to a combination of empirical…

This paper addresses questions raised about the validity of facilitated communication with autistic individuals and others having severe disabilities and offers examples from the authors' program to support the validity of facilitated communication. Published studies showing a high rate of unfounded claims of abuse under facilitated communication…

This study, with 96 sales clerks, examined conversational trade-offs with customers using augmentative or alternative communication (AAC) in scripted videotaped conversational conditions. The clerks rated the conditions involving slowly delivered relevant messages higher than quickly delivered partly relevant messages. Also, messages preceded by a…

This study examined the frequency and nature of augmented input that adult partners provided to 13 youth with moderate to severe mental retardation as they began to use the System for Augmenting Language. Analyses revealed differences in the frequency and in the manner and style with which home and school partners provided augmented input.…

Facilitated communication (FC) as an augmentative or alternative communication system was evaluated with 14 students having autism. At the end of 10 weeks of instruction, no participants were able to produce functional, typed communication, thereby failing to support the cause-effect relationship proposed by FC proponents. (DB)

This study evaluated the use of TALK, a computer-based augmentative and alternative communication (AAC) system, in the social communications of a nonvocal woman with motor neurone disease. She was able to achieve an average conversational rate of 42 words per minute (wpm) using TALK, compared with 2 to 10 wpm with other AAC systems using…

Six individuals (ages 10 to 44) with communication disorders who used augmentative and alternative communication were provided instruction on the acquisition, generalization, and long-term maintenance of partner-focused questions. Instruction used least-to-most prompting hierarchy in real-world interactions and simulations. All subjects learned…

This study evaluated the use of facilitated communication (FC) paired with a direct instructional strategy to improve the basic academic skills of 12 youths and young adults with autism. Results did not support use of FC as an educational tool, with subjects averaging below-chance performance in FC and both control conditions. (DB)

This study of an adolescent with multiple disabilities, including moderate mental retardation, who was reported to engage in validated facilitated communication (FC) found he did not engage in validated FC; performance was equivalent whether food or nonfood reinforcers were used; and the Picture Exchange Communication System was a valid and…

Potential individual variations in the effectiveness of facilitated communication (FC) were examined with 20 students with autism and related disorders. Use of multiple methods (including auditory or visual input, simple point responses, and typing) provided no clear support for validity of FC over students' independent communication. Increased…

This longitudinal study first administered the Uzgiris and Hunt scales (to predict learning of manual signs) to 34 children (mean age 5) with severe and profound mental retardation. Evaluation four years later indicated that achievement of stage five on the Uzgiris and Hunt scales was necessary for even minimal learning and use of manual signs.…
