Discusses the cognitive processes involved in constructing linear orderings from pairwise relationships of information items. Examines the effects that sentence types used in presenting information have on these processes, and tests two models designed to clarify the acquisition of spatial knowledge and the processing of locative and comparative…

Two experiments tested a set of predictions regarding category definitions and categorization latencies. Neither prediction was supported by the experiment results, leading to the formulation of an alternative feature-based model of category definitions using the notion of a polymorphous concept.

A Markov model was proposed to account for the short-term retention of the spatial arrangement of letters. The model was fit to three spatial location recall conditions in experiments which differed in distractor task. The rate of information transfer from primary to secondary memory was affected by changes in distractor task. (SW)

This study examines two views of lexical storage and word production, a derivational hypothesis and an independent unit hypothesis. Reaction times and errors were related to derivational complexity. A model of lexical retrieval process incorporating derivational processes is proposed. (Author/SW)

Describes a process model for sentence verification, including sentences expressing the implications of their antecedents. The model's distinctive features are the assumption that verification is based upon a focal element in the test sentence, and the comparison of this element with information corresponding to it in the antecedent…

The "property-set model" is proposed for concept learning and subsequent recognition and classification of old and new exemplars. In an experimental evaluation of alternative models, the property-set model was the best predictor of both recognition and classification performance. (Author/RM)

Describes an experiment to test two assumptions concerning what is stored in the memory with regard to sentence structure: (1) that the linear effect observed is based on a tally model rather than on an integrationist mechanism; (2) that this linear effect is not uniquely the result of a mechanism operating at comprehension. (CLK)

Presents a computer simulation testing semantic networks and spreading activation models of human memory. Describes how a sentence is encoded by building a working memory structure from its words and from semantic memory concepts related to its meaning. Retrieval processes use cue words or sentences to locate working memory structures. (Author/MES)

Two experiments investigated the relationship of verification to the answering of yes-no questions. Subjects verified simple statements or answered simple questions. Various proposals concerning the relative difficulty of answering questions and verifying statements were considered, and a model was proposed. (SW)

This study deals with the patterns of word-by-word reading times over a sentence when the subject must code the linguistic information sufficiently for immediate verbatim recall. A class of quantitative models is considered that would account for reading times at phrase breaks. (Author/RM)

Discusses a sequential, three-stage model of how nonliteral expressions are understood, as proposed in recent linguistic, philosophical, and psychological studies. Testing the model's implication that nonliteral meanings of sentences are ignored whenever literal meanings are plausible, finds evidence that both meanings are processed simultaneously…
