Abstract

We classified and analyzed the speech errors of 15 individuals during the acute recovery stage from aphasia. Results from the regression analysis revealed that 3 error types were prognostically significant for recovery of language function at 8 months. Semantically-related errors and target-related neologisms produced initially were associated with good outcome, and conversely “no responses” with poor outcome. Initial speech errors systematically converted to “smarter” errors at eight months. Our results support Bhatnagar’s et al’s (2004) observation that lexical deficits and their sequential resolution are correlated to the changing physiology of the brain as it recovers.
