What is the relation between factual conditionals: "If A happened then B happened," and counterfactual conditionals: "If A had happened then B would have happened?" Some theorists propose quite different semantics for the two. In contrast, the theory of mental models and its computer implementation interrelates them. It…

Word learning depends critically on the use of linguistic context to constrain the likely meanings of words. However, the mechanisms by which children infer word meaning from linguistic context are still poorly understood. In this study, we asked whether adults (n = 58) and 2- to 6-year-old children (n = 180) use discourse coherence relations…

We examine metonymy at psycho- and neurolinguistic levels, seeking to adjudicate between two possible processing implementations (one- vs. two-mechanism). We compare highly conventionalized "systematic metonymy" (producer-for-product: "All freshmen read 'O'Connell'") to lesser-conventionalized "circumstantial…

According to one view of linguistic information (Karttunen, 1974; Stalnaker, 1974), a speaker can convey contextually new information in one of two ways: (a) by "asserting" the content as new information; or (b) by "presupposing" the content as given information which would then have to be "accommodated." This…

Recent years have seen a surge in accounts motivated by information theory that consider language production to be partially driven by a preference for communicative efficiency. Evidence from discourse production (i.e., production beyond the sentence level) has been argued to suggest that speakers distribute information across discourse so as to…

This paper surveys work on applying the insights of lexicalized grammars to low-level discourse, to show the value of positing an autonomous grammar for low-level discourse in which words (or idiomatic phrases) are associated with discourse-level predicate-argument structures or modification structures that convey their syntactic-semantic meaning…
