Jeanette Gundel, Nancy Hedberg, and I finally got our paper, Underspecification of Cognitive Status in Reference Production: Some Empirical Predictions accepted to the journal, Topics In Cognitive Science, a journal of the Cognitive Science Society. It will be appearing in the special issue on “Production of Referring Expressions: Bridging the Gap between Computational and Empirical Approaches to Reference.” Within the Givenness Hierarchy framework we outlined in our 1993 paper, lexical items included in referring forms are assumed to conventionally encode two kinds of information: conceptual information about the speaker’s intended referent and procedural information about the assumed cognitive status of that referent in the mind of the addressee. In this current paper we explore the role of underspecification of cognitive status in reference processing.We show how this framework accounts for a number of experimental results in the literature.
