Presuppositions, Projection, and Accommodation
This chapter reviews experimental work on presupposition, both in terms of methodological developments and the theoretical implications of experimental results. Presuppositions convey information that is typically assumed to already be taken for granted by the discourse participants. Furthermore, they are characteristically unaffected by a variety of linguistic embedding environments, such as negation, conditionals, and questions. After providing a brief background on the topic, and introducing key issues from the current literature, experimental approaches to investigating presuppositions are discussed, covering both unembedded and embedded environments, as well as the relation of presuppositions to the discourse context. The final section concludes and provides an outlook on future directions for the field.
