- Coherence (Linguistics)
Discourse coherence may be conceptualized as representing the listener's ability to interpret the overall meaning conveyed by the speaker. Discourse schemas serve as the organizing frameworks for placing the essential discourse elements within a language sample (Bloom, Borod, & Santschi-Haywoor, Pick, & Obler, 1996; Peterson & McCabe, 1983). When the essential elements are provided a logical consistency of the discourse schema is maintained and the listener perceives the discourse as coherent (Ditman & Kuperberg, 2010; Trabasso, van den Broek, & Suh, 1989; van den Broek, Virtue, Everson, Tzeng, & Sung, 2002). Global coherence refers to the ability to semantically relate remote utterances in the framework of a given discourse (Marini et al., 2011) and is the focus of the current study. Utterances that are tangential, conceptually incongruent with the story, repetitions, and fillers may all negatively affect maintenance of global coherence.
