Abstract

This study examined production and comprehension of nouns and verbs using the Northwestern Naming Battery (NNB), a new test designed to assess naming ability in individuals with stroke-induced or primary progressive aphasia (PPA). Scores derived from the NNB were also compared to scores from published, standardized tests to evaluate the NNB’s validity. Dissociations between word classes in production were observed for participants with stroke-induced anomic and Broca’s aphasia with agrammatism and individuals with logopenic and agrammatic variants of PPA, with the two agrammatic groups showing greater impairment for verb compared to noun naming. Clinical and theoretical implications will be discussed.
