Description
Summary:Word/picture verification has been found to be a sensitive measure of lexical-semantic abilities in post-stroke aphasia and reveals information about disruptions in semantic and phonological processing. Exploration of the nature of auditory comprehension deficits using word/picture verification has not been replicated in primary progressive aphasia (PPA). We tested 108 individuals with PPA [logopenic variant PPA (lvPPA), n = 50; nonfluent agrammatic PPA (nfaPPA), n = 36; semantic variant PPA (svPPA), n = 22] on a spoken word/picture verification task and a spoken word/picture matching task. The spoken word/picture matching task identified 22 (20%) of individuals as impaired, whereas the spoken word/picture verification task identified 51 (47%) of individuals as impaired (two-tailed p
