摘要：Discourse coherence may be conceptualized as representing the listener’s ability to interpret theoverall meaning conveyed by the speaker. Discourse schemas serve as the organizing frameworksfor placing the essential discourse elements within a language sample (Bloom, Borod, SantschiHaywoor, Pick, & Obler, 1996; Peterson & McCabe, 1983). When the essential elements areprovided a logical consistency of the discourse schema is maintained and the listener perceives thediscourse as coherent (Ditman & Kuperberg, 2010; Trabasso, van den Broek, & Suh, 1989; van denBroek, Virtue, Everson, Tzeng, & Sung, 2002). Global coherence refers to the ability to semanticallyrelate remote utterances in the framework of a given discourse (Marini et al., 2011) and is the focusof the current study. Utterances that are tangential, conceptually incongruent with the story,repetitions, and fillers may all negatively affect maintenance of global coherence.
