Echo questions as a means of building coherence in conversational discourse

The study focuses on the cognitive-communicative characteristics of echo questions in English conversational discourse. Drawing on van Dijk's sociocognitive (mental model) theory and cognitive discourse analysis, the paper suggests viewing echo questions as a means of building/updating a mental context model of a communicative situation.

Based on the mental model theory, the study offers a typology of misunderstandings corrected by echo questions
