This article argues that multisentence discourses give rise to Gricean quantity implicatures that go beyond the mere sum of the implicatures of the sentences they consist of. We formulate two theories of discourse-level implicature: the null theory, which only has a mechanism for sentence-level implicature and does not rely on any specific notion…

Purpose: The goal of the current research study was to advance our knowledge of cognitive-communicative disorders following traumatic brain injury (TBI) by identifying the cognitive and communicative processes underlying narrative discourse ability. The study (1) examined the role of working memory (WM) and inferencing in narrative discourse, (2)…

This thesis describes new approaches to the formal modeling of narrative discourse. Although narratives of all kinds are ubiquitous in daily life, contemporary text processing techniques typically do not leverage the aspects that separate narrative from expository discourse. We describe two approaches to the problem. The first approach considers…

Investigates the hypothesis that one of the processes used in situation model development is an inferential process in which the reader employs knowledge to form expectations when predictive text opportunities arise. Suggests that predictions are available to the reader at an abstract level of representation. (HB)

Outlines three basic views of how readers infer causal connections and how they generate causal inferences. Evaluates these three hypotheses with reference to current research in the field. (HB)

Discusses the differences among current researchers interested in inferences, including the types of inferences studied and the methodologies used. Presents a theoretical and methodological framework for organizing empirical investigations of inferential processes of reading. (HB)

Considers the difference between commonplace inferences versus more elusive inferences in reading processes. Claims that higher level inferences may be restricted in part because they do not operate in response to simple memory symbols but depend on complex compositional representations not always available. (HB)

Suggests that the term "inference" itself has had a negative effect on the study of how information is elaborated and reduced in text processing. Discusses some of the current views of inferencing in text comprehension. Suggests viewing information reduction processes within the same framework as information accretion. (HB)

Considers whether causal antecedent and causal consequence inferences are generated on-line during comprehension and also determined the time course of their activation. Supports a bridging model of inference generation, since causal antecedents were generated online, whereas causal consequences were not. (HB)

Argues that an adequate theory of inference generation should accurately predict whether particular classes of knowledge-based inferences are generated online during text comprehension. Proposes a "constructionist" theory which accounts for the findings of cognitive psychology and discourse processing. (HB)

In recent years several mathematics education researchers have attempted to analyse students' arguments using a restricted form of Toulmina's ["The Uses of Argument," Cambridge University Press, UK, 1958] argumentation scheme. In this paper we report data from task-based interviews conducted with highly talented postgraduate mathematics students,…

Studies whether global, causal inferences are made during comprehension. Provides verbal protocol data in the form of talking aloud during reading. Discusses the data with reference to processing claims and working-memory models. Considers what verbal protocols reveal about processing. (HB)
