Concludes that, whereas inference processing may be impeded by the relative lack of familiarity of the content of expository text, it is not strictly precluded. Indicates rather that inference processing in the comprehension of expository text is regulated by the information-processing constraints of the reading task and by the discourse and…

Tests two views of how relevant global information becomes readily available to readers. Demonstrates that backgrounded information became readily available if it shared features in common with the current contents of working memory. Shows that this occurred independently of whether the information was relevant or thematically related;…

Presents principles of dialog cooperativity derived from a corpus of task-oriented spoken human-machine dialog. Analyzes the "corpus" to produce a set of dialog design principles intended to prevent users from having to initiate clarification and repair metacommunication that the system would not understand. Proposes a "more…

Investigates the degree to which listeners are sensitive to the social relations expressed in choice of a name when referring to a third person during a conversation. Concludes that the social information inherent in names is picked up by readers and encoded into memory. (HB)

Analyzes different strategies used by speakers/writers and hearers/readers to deal with underspecified coherence relations, phrased in terms of Horn's (1984) Q- and R- principle. Presents data from the psycholinguistic literature on the interpretation of underspecified relations and data from language-acquisition research suggesting that both…

Hypothesizes a resonance process in which concepts and propositions in the discourse resonate in response to related elements in the current sentence, initiating a process that makes available a subset of the information in the representation. Reviews research; presents explicit assumptions about the discourse representation; and describes results…

Provides a definition of comparison questions and shows how they relate to the semantic categories of two taxonomies for classifying questions, both of which omit comparison questions. Examines the comparison questions that auditors generate when they diagnose problems in a company. (SR)

Contributes to communication theory and research by adding to a discussion of a computational model called latent semantic analysis (LSA). Argues that LSA does not handle all aspects of language processing, but offers a biologically and psychologically plausible mechanistic explanation of the acquisition, induction, and representation of verbal…

Finds that temporal markers modify the availability of preceding words: segmentation markers like "around two o'clock" and "then" reduce this availability, whereas continuity markers like "and" improve this availability. Supports the hypothesis that segmentation markers lead readers not to integrate new information…

Examines how type of referent (name versus pronoun) influences comprehension of short passages. Provides strong support for central predictions of centering theory: (1) using a repeated name to refer to the central entity of a discourse disrupts comprehension; and (2) this disruption interacts with whether there is a continuing or shifting…

Proposes the subsuming theory criterion for experiments on common ground in mutual knowledge (i.e., the design must keep common information constant and only vary whether or not it is common). Demonstrates how doing so makes stronger claims. Illustrates how experiments can be designed to satisfy the criterion by evaluating some earlier studies…

Describes the seven main components of QUEST, a cognitive model of question answering that attempts to simulate the answers adults produce when they answer different types of questions, both closed class and open class. Illustrates how the model could be applied to different types of knowledge structures, including causal networks, goal…

Tests the QUEST model of question answering in two experiments. Examines which components of QUEST could predict good answers to why-questions and how-questions in the context of short stories. Supports the validity of arc-search procedures and structural distance for both question categories. Finds only partial support for number of information…

Tests the QUEST model of question answering in naturalistic settings and in settings with complex pragmatic constraints: telephone surveys, business interactions, filmed interviews, and interviews on popular television programs. Finds that QUEST explains most of the answers in these contexts and virtually all of the answers that refer to the…

Supports the hypothesis that literal and metaphorical interpretations can result from similar contextual constraints. Finds that a metaphorical interpretation may be selected because a literal interpretation would have been inappropriate and that likewise a literal interpretation may be selected because a metaphorical interpretation would have…
