TL;DR: The present paper shows how the extended theory can account for results of several production experiments by Loftus, Juola and Atkinson's multiple-category experiment, Conrad's sentence-verification experiments, and several categorization experiments on the effect of semantic relatedness and typicality by Holyoak and Glass, Rips, Shoben, and Smith, and Rosch.
Abstract: This paper presents a spreading-acti vation theory of human semantic processing, which can be applied to a wide range of recent experimental results The theory is based on Quillian's theory of semantic memory search and semantic preparation, or priming In conjunction with this, several of the miscondeptions concerning Qullian's theory are discussed A number of additional assumptions are proposed for his theory in order to apply it to recent experiments The present paper shows how the extended theory can account for results of several production experiments by Loftus, Juola and Atkinson's multiple-category experiment, Conrad's sentence-verification experiments, and several categorization experiments on the effect of semantic relatedness and typicality by Holyoak and Glass, Rips, Shoben, and Smith, and Rosch The paper also provides a critique of the Smith, Shoben, and Rips model for categorization judgments Some years ago, Quillian1 (1962, 1967) proposed a spreading-acti vation theory of human semantic processing that he tried to implement in computer simulations of memory search (Quillian, 1966) and comprehension (Quillian, 1969) The theory viewed memory search as activation spreading from two or more concept nodes in a semantic network until an intersection was found The effects of preparation (or priming) in semantic memory were also explained in terms of spreading activation from the node of the primed concept Rather than a theory to explain data, it was a theory designed to show how to build human semantic structure and processing into a computer

Journal ArticleDOI
TL;DR: The ACT theory of factual memory as mentioned in this paper states that information is encoded in an all-or-none manner into cognitive units and the strength of these units increases with practice and decays with delay.

Journal ArticleDOI
TL;DR: A computer model that implements the spreading-activation theory of conceptually driven lemma retrieval is shown to be able to account for many basic findings on the time course of object naming, object categorization, and word categorization in the picture-word interference paradigm.

Journal ArticleDOI
TL;DR: The FUSS model can capture generalizations presented in the literature, in particular those related to category-related deficits, and can predict semantic effects in behavioral experiments for object and action words better than other models such as Latent Semantic Analysis.
