Plasticity in Memorial Networks
Hayes-Roth, Barbara; Hayes-Roth, Frederick – Journal of Verbal Learning and Verbal Behavior, 1975
An adaptive network model is proposed to represent the structure and processing of knowledge. Accessibility of subjects' stored information was measured. Relationships exist among (a) frequency of verifying a test relation, (b) other relations involving concepts used to evaluate test relation, (c) frequency of verifying those relations. (CHK)

The Prominence of Lexical Information in Memory Representations of Meaning
Hayes-Roth, Barbara; Hayes-Roth, Frederick – Journal of Verbal Learning and Verbal Behavior, 1977
Many theories of memory assume memory representations are abstract and exclude specific lexical information. Results of three experiments in this study suggest lexical information is present and persists in memory representations of meaning. A word-based theory of memory should be preferred over available theoretical alternatives. (CHK)

Text Annotation: A Technique for Facilitating Knowledge Integration.
Miller, James R.; Hayes-Roth, Barbara – 1977
Thirty-six undergraduate students participated in a two-hour experiment that measured the effect of fact and inference text annotation on the integration of information. The subjects were asked to read four pairs of meaningful stories, each of which contained four pairs of related facts about a mythical country. The texts of the experimental group…

Concept Learning and the Recognition and Classification of Exemplars
Hayes-Roth, Barbara; Hayes-Roth, Frederick – Journal of Verbal Learning and Verbal Behavior, 1977
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)

Hayes-Roth, Barbara – Psychological Review, 1977
The knowledge-assembly theory is proposed to explain the acquisition, representation, and processing of knowledge. The theory assumes that both the representation and processing of knowledge change qualitatively as learning progresses. (Editor)

Structurally Integrated Versus Structurally Segregated Memory Representations: Implications for the Design of Instructional Materials.
PDF on ERIC Download full text
Hayes-Roth, Barbara – 1977
Two kinds of memory organization are distinguished: segregrated versus integrated. In segregated memory organizations, related learned propositions have separate memory representations. In integrated memory organizations, memory representations of related propositions share common subrepresentations. Segregated memory organizations facilitate…

Lexical Information in Memory for Text.
Hayes-Roth, Barbara – 1977
Cued-recall and two-alternative, forced-choice recognition measures were used to evaluate subjects' retention of the specific wordings of studied texts. Results obtained after 10-minute and 24 hour retention intervals suggest that the studied wordings of texts are functional components of their memory representations. Theories that assume…
