Showing papers in "Cognitive Science in 1979"

TL;DR: A cognitive model of the planning process that generalizes the theoretical architecture of the Hearsay-II system and illustrates its assumptions with a “thinking aloud” protocol is presented and the performance of a computer simulation of the model is described.

TL;DR: In this paper, formal definitions are given for several coherence relations, based on the operations of an inference system; that is, the relations between successive portions of a discourse are characterized in terms of the inferences that can be drawn from each.

TL;DR: This paper explores the truism that people think about what they say and proposes that, to satisfy their own goals, people often plan their speech acts to affect their listeners' beliefs, goals, and emotional states.

TL;DR: Seven features which in practice seem to differentiate belief systems from knowledge systems are discussed, including nonconsensuality, “existence beliefs” alternative worlds, evaluative components, episodic material, unboundedness, and variable credences.

TL;DR: There appears to be a deep-rooted psychological tendency for a representational tool which functions well procedurally to become subsequently a problem-space per se.

TL;DR: In this article, it is argued that complex objects are assigned hierarchical structural descriptions by being parsed into parts, each of which has its own local system of significant directions, and that the difficulty of certain mental imagery tasks is dependent on which of the alternative structural descriptions of an object is used, and interpreted as evidence that structural descriptions are an important component of mental images.

TL;DR: A story content oriented approach to studying story understanding is advocated instead of the structural story grammar approach because grammars would add nothing to semantic models that focus on the story content.

TL;DR: The purpose of this note is to call attention to the dative neglect of the "problem of the problem" by offering some tentative observations regarding the significance of problem finding in thought, the nature and variety of problems, and the human being as problemfinder.

TL;DR: A new approach to natural language processing is described which results in a very robust and efficient system which enables the parser to benefit from predictions that the rest of the system makes in the course of its processing.

TL;DR: It is argued that knowledge about actions and interactions can account not only for how stories are constructed, but also for why some stories are more interesting and enduring than others.

TL;DR: It is shown that identifying and configuring relevant facts in order to support hypothesized inferences is extremely difficult unless the facts have been committed to memory, and a model of search and memory mechanisms is proposed.

TL;DR: Two descriptions of KRL are presented to the A1 community which explicate both a high level A1 programming language and a theory of knowledge representation, and each represents a courageous break by the two authors from their past opinions.

TL;DR: The mechanisms a program may use to learn conceptual structures that represent natural language meaning, along with the conditions under which each is invoked and the effect each has on existing memory structures are described.

TL;DR: In Experiments 3 and 4 incongruent world knowledge slowed response times for both inference types, suggesting that linguistic and factual knowledge are both part of the initial representation of a sentence.

TL;DR: The question is prompted by Eugene Charniak's (1978) recent editorial introducing the new 'Theoretical Notes' section, which is excellent, but I am dubious about one aspect of it.
