Word Retrieval Measures with the AphasiaBank Stimuli: Test-Retest Reliability Proposal for CAC 2014

TL;DRAbstract

Research into treatment for improving word retrieval ability in aphasia is increasingly focused on assessing outcomes at a discourse level. For example, the AphasiaBank project (http://talkbank.org/AphasiaBank/ ) uses a number of tasks to elicit discourses from individuals with aphasia. The discourses can then be analyzed with a set of analysis tools from the Computerized Language Analysis (CLAN) system. MacWhinney, Fromm, Holland, Forbes, & Wright (2010) have suggested that the AphasiaBank tools can be used to study recovery from aphasia and the effects of aphasia treatments. The AphasiaBank protocol is promising because of its ability to quickly and accurately perform a number of analyses that are time-consuming, cumbersome, and vulnerable to error when performed manually. However, except for a report on VOCD, a measure of lexical diversity that is part of the CLAN system (Boyle, 2013), there have been no reports about the test-retest reliability of the various language measures incl
