The use of computers and augmentative and alternative communication devices in independent naming practice: Three single-case studies

Computers and augmentative and alternative communication (AAC) devices were used for independent naming practice by individuals with chronic non-fluent aphasia and verbal apraxia. Three participants practiced 10 words on a home computer (Computer Practice) and 10 words on a high-tech AAC device (AAC Device Practice). The two practice conditions were implemented as home practice programs. Verbal naming performance was assessed at baseline, during the practice period (after 5-, 10-, and 15-weeks of practice), and 4-8 weeks post-treatment. Computer Practice significantly improved verbal naming for all participants. AAC Device Practice did not yield significant improvements; however, there was a trend for participants to require less support in naming items. Differences in procedures and motivation were likely contributors to the contrasting outcomes of the two practice conditions.
