Meaning and form in coreference processing
The study of pragmatics examines the mechanisms underlying speakers' ability to construct meaning in context and comprehenders' ability to infer meaning beyond what a speaker has explicitly said. These abilities are taken to depend both on the properties of what is said as well as on considerations of what isn't said. In this talk, I present a series of psycholinguistic studies that highlight how coreference is sensitive to inferences about likely meanings (over possible underlying coherence relations) and estimates of likely forms (choice of referring expression). The studies are framed in terms of Bayesian updating: how do comprehenders estimate the probability of different messages and the likelihood of different forms for expressing those messages? A number of properties at the levels of events, discourse structure, and utterance formulation help comprehenders estimate upcoming material (probabilities over possible messages); the context of alternative forms is shown to influence how speakers refer and how comprehenders interpret those forms (probabilities over choice of referring expression). hat is most intriguing about the data is the apparent independence of contributions from factors related to message meaning and those related to message form.
