Three experiments investigated factors influencing the integration of facts acquired from texts. Subjects encountered related facts in the context of relatively long, meaningful texts, a single text, or in two separate texts. Results indicate that integration can occur in both cases. (SW)

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)

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)

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)
