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)

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)

Investigates how readers use predication for the interpretation of referents in text and to develop a coherent model of the events described in text. Illustrates how two types of predication (scalar copredication and antipredication) induce readers to disambiguate the referents of definite noun phrases in essentially the opposite way, with…

Analyzes the distribution of 33 linguistic markers of complexity across 23 spoken and written registers of English. Identifies a five-dimensional model and uses it to describe the complexity characteristics of spoken and written registers. Finds that, whereas written registers exhibit profiles differing widely in extent and kind of complexity,…

Concludes that spatial information is available to readers only under very specific conditions. Notes that readers told to focus on spatial details had the information available, but that, when told to read for comprehension, spatial information did not become available. Finds also that spatial information was available only when it was required…

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…

Explores whether speakers choose spatial perspectives to minimize effort. Discusses an experiment in which speakers describe locations on a display for addressees who shared their vantage point or had different views. Finds that same-viewpoint speakers spoke differently from speakers with offset views, who did not differ from each other reliably,…

Describes a computational model of high-dimensional context space: the Hyperspace Analog to Language (HAL). Shows that HAL provides sufficient information to make semantic, grammatical, and abstract distinctions. Demonstrates the cognitive compatibility of the representations with human processing; and introduces a new methodology that extracts…

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…

Proposes a "partial explanatory" model of document processing. Describes research underlying the model, presents a grammar of documents, defines and illustrates the variables underlying the model using a set of tasks relating to a bus schedule, and demonstrates the advantages of explanatory over exploratory models of document processing. (SR)

Tests and confirms two hypotheses about the representation of knowledge in memory: that a person's mental representation of a newly learned body of knowledge has two parts (the information presented, and a product of the person's thinking about it); and that a body of knowledge learned from experience is organized into distinct…

Presents evidence that indicates recognition memory consists of three separate representations: a surface representation, a propositional textbase, and a situation model. (KEH)
