Abstract

This investigation measured performance of individuals with aphasia on working memory tasks targeting their processing of different information types (phonological, semantic, and structural/syntactic). Participants included 3 adults with aphasia. Tasks included a listening span and three novel n-back tasks. The n-back tasks were presented auditorily, and measured both active working memory maintenance ("identity" level) and processing ("depth" level) for each information type. Results indicate that the tasks may be able to differentiate individual performance along the lines of aphasia classification categories, suggesting that the modified n-back tasks may lead to a more precise description of aphasic performance.
