C = canonical; NC = non-canonical; A= active; P = passive; SWQ = subject extracted wh-question; OWQ = object extracted wh-question; SR = subject relative clause; OR = object relative clause; Under the heading of ‘by canonicity’, the superscript “a” indicates significant difference between canonical and non-canonical forms (p < 0.05). Under the heading of ‘by sentence type’, the superscript “b” indicates significant difference between a structure as compared with others (p < 0.05). Superscript numbers indicate significant difference between a structure as compared to active¹, SWQ², OR³, passive⁴, OWQ⁵, SR⁶ at the level of p < .05.
