UNLABELLED Evaluation of client progress is an important topic in communicative disorders research and clinical literature. Goal attainment scaling (GAS) is a technique for evaluating individual progress toward goals. Despite recognition of GAS as a clinical-outcome assessment technique in other clinical professions, the current debate on measuring client(More)
Students with developmental disabilities and limited or no functional speech often use speech-generating devices. While the speech-output function of such devices is considered to have potential advantages, it is unclear whether the length of synthetic speech output influences augmented communication and natural speech production. To this end, we describe a(More)
In this systematic replication of a previous study (R. W. Schlosser, D. M. Blischak, P. J. Belfiore, C. Bartley, and N. Barnett, 1998), the effects of speech and print feedback on spelling performance were evaluated. Four children with autism and no functional speech were taught to spell words with a speech-generating device under 3 feedback conditions. In(More)
The concept of evidence-based practice (EBP) is omnipresent in medicine and allied health care and is gradually gaining a foothold in rehabilitation and disability as well (NCDDR, 2006). EBP is defined as the integration of best and current research evidence and clinical/educational expertise with relevant stakeholder perspectives to inform decisions(More)
OBJECTIVE To assess undergraduates' perceptions of three augmentative and alternative communication (AAC) modes. METHOD We showed 104 undergraduates a video clip of a person using each of the three AAC modes and asked them to rate each option in terms of perceived (a) intelligibility, (b) ease of acquisition, (c) effectiveness/acceptability, and (d)(More)
BACKGROUND Children with neurodevelopmental disorders often present with little or no speech. Augmentative and alternative communication (AAC) aims to promote functional communication using non-speech modes, but it might also influence natural speech production. METHOD To investigate this possibility, we provided AAC intervention to two boys with(More)
