Does category size affect categorization time

01 Aug 1970-Journal of Verbal Learning and Verbal Behavior (Academic Press)-Vol. 9, Iss: 4, pp 432-438
TL;DR: The authors found that it takes longer to categorize object names (e.g., collie or tulip) into larger categories than into smaller categories, and attributed this effect to the fact that their different-size categories were always nested.
About: This article is published in Journal of Verbal Learning and Verbal Behavior.The article was published on 1970-08-01. It has received 132 citations till now. The article focuses on the topics: Categorization.

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

TL;DR: A theory of memory retrieval is developed and is shown to apply over a range of experimental paradigms, and it is noted that neural network models can be interfaced to the retrieval theory with little difficulty and that semantic memory models may benefit from such a retrieval scheme.
Abstract: A theory of memory retrieval is developed and is shown to apply over a range of experimental paradigms. Access to memory traces is viewed in terms of a resonance metaphor. The probe item evokes the search set on the basis of probe-memory item relatedness, just as a ringing tuning fork evokes sympathetic vibrations in other tuning forks. Evidence is accumulated in parallel from each probe-memory item comparison, and each comparison is modeled by a continuous random walk process. In item recognition, the decision process is self-terminating on matching comparisons and exhaustive on nonmatching comparisons. The mathematical model produces predictions about accuracy, mean reaction time, error latency, and reaction time distributions that are in good accord with experimental data. The theory is applied to four item recognition paradigms (Sternberg, prememorized list, study-test, and continuous) and to speed-accuracy paradigms; results are found to provide a basis for comparison of these paradigms. It is noted that neural network models can be interfaced to the retrieval theory with little difficulty and that semantic memory models may benefit from such a retrieval scheme.

TL;DR: The authors showed that the language-as-fixed-effect fallacy can be avoided by doing the right statistics, selecting the appropriate design, and sampling by systematic procedures, or by proceeding according to the so-called method of single cases.

TL;DR: KRL is an attempt to integrate procedural knowledge with a broad base of declarative forms to give flexibility in associating procedures with specific pieces of knowledge, and to control the relative accessibility of different facts and descriptions.

TL;DR: The results of a true-false reaction-time task were found to support the hypothesis about memory organization that a canary is a bird and birds can fly.
Abstract: To ascertain the truth of a sentence such as “A canary can fly,” people utilize long-term memory. Consider two possible organizations of this memory. First, people might store with each kind of bird that flies (e.g., canary) the fact that it can fly. Then they could retrieve this fact directly to decide the sentence is true. An alternative organization would be to store only the generalization that birds can fly, and to infer that “A canary can fly” from the stored information that a canary is a bird and birds can fly. The latter organization is much more economical in terms of storage space but should require longer retrieval times when such inferences are necessary. The results of a true-false reaction-time task were found to support the latter hypothesis about memory organization.

TL;DR: This fifth edition brings Roget's original category concept towards the 21st century, including 31 entirely new categories, such as computers, fitness and exercise, and all kinds of sport.
Abstract: This thesaurus is based on the system devised by Peter Roget for his original thesaurus of 1852. Words and phrases are arranged according to the ideas or concepts that they express within an overall system of categories and classes. Thus the user can start from an idea and explore different ways to express it. This fifth edition brings Roget's original category concept towards the 21st century. 325,000 words and phrases are grouped by concept into 1073 categories with all synonyms, antonyms and related words presented together for quick and easy reference. The text has been fully revised and expanded, including 31 entirely new categories, such as computers, fitness and exercise, and all kinds of sport. The whole range of language from archaisms to the latest slang (labelled) is included.
