Proposes an alternative model of language comprehension regarding how people understand idioms in which literal meanings are systematically used to constrain the use and variation of conventional idioms and to generate novel idiom variance. Presents three experiments on how people process variant idioms. (SR)

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…

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…

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…

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…

Outlines the scenario-mapping and focus (SMF) account of text interpretation, which puts mapping of text onto knowledge in a key position with respect to processing. Reviews supporting evidence. Uses plural reference and nonlogical quantification as illustrations of problems that might be better understood within the SMF framework. (SR)

Presents three mini-essays reviewing progress made on three problems in text comprehension (two traditional and one newer problem): their relationship between sentence processes and text processes; individual differences in discourse comprehension; and the representation of multiple-text information, which exposes fresh views of problems of…

Notes that memory-based text processing (MBP) is a label that has been used to refer to a theoretical perspective shared by contributors to this special issue. Defines the domain addressed by MBP; identifies the major shared assumptions of researchers representing the MBP perspective; and raises some challenges for MBP researchers. (SR)

Proposes a top-down procedural model for the dynamic extraction and use of context structure to resolve references. (FL)
