The purpose of this study was to gather normative data bearing on the hierarchical organization of semantic memory. (Author)

To what extent does prior knowledge of a superordinate category facilitate recognition of an instance of that category? The results of this study reveal that the facilitating effect of a category prime on perceptual processing is inversely related to the quality of the stimulus information available. (Author/RK)

The salience of encoding attributes in instances of differing levels of category membership was examined using the release from proactive interference (PI) task with college students. Results are discussed in terms of providing converging evidence for Rosch's (1973,1975) theory of semantic category structure. (Editor/RK)

Two experiments demonstrate that individuals are limited in the number of unrelated words they can apprehend and assign to a particular semantic dimension and also that retrieval from long-term memory is subject to the same kind of limitation. (Author/RK)

The latency to classify a test item as not being from a memorized list of category words is usually slower when the test items are categorically related to memorized words than when they are unrelated. This observation has been explained by four models of recognition, which are evaluated here. (Editor/RK)

Four experiments were conducted where words were recalled after presentation either in hierarchical fashion or in a matrix. The intention was to examine whether the original advantage for hierarchical retrieval systems could be duplicated for matrix systems, and if there was any particular advantage or disadvantage for either type of structure.…

The ability of preverbal infants to abstract a prototypical representation of a category, when presented with examples of an artifically constructed category, was investigated. It was determined that infants could process visual information constructively and could take a more active role in category formation than previously believed. (Author/MH)

Two codes that provide access to the identity of an item in memory are the initial letter of its name and the name of a category to which it belongs. This research compares the characteristics of these two modes of access to the identity of a memory trace. (Author/RK)
