ASPT-A = Argument Structure Production Test, Code A; ASPT-G = Argument Structure Production Test; Code G; ASPT-W = Argument Structure Production Test, Code W; ASPT-2–1 = Argument Structure Production Test, 2–1; ASPT-3–1 = Argument Structure Production Test, 3–1; NAVS = Northwestern Assessment of Verbs and Sentences; NC-C = Noncanonical minus canonical; SCT = Sentence Comprehension Test; SPPT = Sentence Production Priming Test; WAB-R = Western Aphasia Battery-Revised, aphasia quotient.
Correlation is significant at the 0.05 level (uncorrected; two-tailed); n range = 64–71 (not all participants were able to complete all NAVS tasks).
Correlation is significant at the 0.0009 level (p < 0.05 with Bonferroni correction; two-tailed).
