SPPT = Sentence Production Priming Test; SCT = Sentence Comprehension Test; Agr = agrammatic; An = anomic; C = canonical sentences; NC = non-canonical sentences; SWQ = subject extracted wh-question; OWQ = object extracted wh-question; SR = subject relative clause; OR = object relative clause. By canonicity, aindicates p < .013 for between-group comparisons and 0indicates p < .01 for within-group comparisons. By sentence type, bindicates p < .0042 for between-group comparisons, and each superscript number indicates significantly greater difficulty with a particular structure compared to active1, SWQ2, SR3, passive4, and OWQ5 at least p < .05 within each group.
