Note: Western Aphasia Battery Aphasia Quotient (WAB AQ) is a composite score of 10 WAB subtests that represents aphasia severity; a score <93.8 is considered aphasic (Kertesz, 1982). BNT represents the total correct of 60 items from the Boston Naming Test (Kaplan, Goodglass, & Weintraub, 1983). PPVTrs represents the total correct of 228 items from the Peabody Picture Vocabulary Test-IV. PPVTss represents patients’ scaled score on the PPVT-IV (M = 100, SD = 15) (Dunn & Dunn, 1997). Speech rate is defined as the number of discrete syllables produced per second as participants completed a narrative speech sample. Speech productivity represents the ratio of total speaking time without silences over total speaking time with silences during a given interval. Audible struggle represents the average rating on articulatory struggle by three independent speech-language pathologists evident during one’s production (1 = most struggle, 5 = least struggle) (Park et al., 2011).
