Bookstein, Abraham; Klein, Shmuel T. – Information Processing and Management, 1992
Presents new methods for compressing bit matrices in large information retrieval systems which exploit possible correlations between rows of words and columns of documents. Three encoding methods are tested and compared--Shannon-Fano, arithmetic, and Huffman--and an appendix discusses binomial coefficients. (20 references) (LRW)

Lieven, Elena V. M.; And Others – Journal of Child Language, 1992
Presents a simple scheme, based on formal categories, for coding stylistic variation in the early lexicon. When applied to the first 50 and 100 words of 12 children between 0;11 and 2;3, the major dimensions of difference are found to be the relative proportion of common nouns and the relative proportion of frozen phrases. (31 references) (GLR)

Wu, Xiaolin; Fang, Yonggang – Information Processing & Management, 1994
Proposes a scheme of hierarchical piecewise linear approximation as an adaptive image pyramid. A progressive image coder comes naturally from the proposed image pyramid. The new pyramid is semantically more powerful than regular tessellation but syntactically simpler than free segmentation. This compromise between adaptability and complexity…

Angelo, Jennifer Burgess – International Journal of Rehabilitation Research, 1990
Two rule-based (truncation and contraction) abbreviation expansion encoding methods and 1 non-rule-based (random) method were evaluated for learning curve and retrieval speed with 66 adults. The truncation method resulted in faster retrieval than the other two methods. Results have implications for training users of augmentative communication…

King, Kevin – System, 1992
Coding tasks, a valuable technique for teaching English as a Second Language, are presented that enable students to look at patterns and structures of marital communication as well as objectively evaluate the degree of happiness or distress in the marriage. (seven references) (JL)
Descriptors: Coding, Communication (Thought Transfer), English (Second Language), Marriage

Reynolds, Barbara E. – College Mathematics Journal, 1993
Discusses the history of different methods of representing numbers and how these representations facilitated counting and computing devices such as the abacus. (MDH)

Processing of Visual--Action Codes by Deaf and Hearing Children: Coding Orientation or "M"-Capacity?

Todman, John; Cowdy, Natascha – Intelligence, 1993
Results from a study in which 25 deaf children and 25 hearing children completed a vocabulary test and a compound stimulus visual information task support the hypothesis that performance on cognitive tasks is dependent on compatibility of task demands with a coding orientation. (SLD)
Descriptors: Children, Coding, Cognitive Processes, Comparative Analysis

Cave, Kyle R.; And Others – Cognitive Psychology, 1994
Three experiments involving 107 adults who performed mental rotation tasks explored how location information is incorporated into image representation. Results suggest that image is coded retinotopically in image representations and that there is no spatiotropic transform in the early stages of visual processing. (SLD)
Descriptors: Abstract Reasoning, Adults, Coding, Cognitive Processes

Dixon, Peter; Di Lollo, Vincent – Cognitive Psychology, 1994
Two experiments involving 12 college students suggest that the visual system codes the temporal relationship between stimuli that occur in close temporal contiguity and that the temporal code determines performance in tasks requiring temporal integration. Potential extension to other visual phenomena is discussed. (SLD)

Spangler, David B. – Mathematics Teaching in the Middle School, 1999
Features a question that focuses on the use of cryptology to teach modes. (ASK)

Greenberg, Jane – Journal of the American Society for Information Science and Technology, 2001
Explores what might be the optimal query expansion (QE) processing method with semantically coded thesauri. Examines whether QE via semantically coded thesauri terminology is more effective in the "automatic" or "interactive" processing environment. Results revealed that synonyms and partial synonyms and narrower terms are…

Johnstone, Theresa; Shanks, David R. – Cognitive Psychology, 2001
Evaluated the contribution of rule, exemplar, fragment, and episodic knowledge in artificial grammar learning using memorization versus hypothesis testing training tasks in 5 experiments involving a total of 163 college students. There was no evidence that memorization led to abstraction of rules or encoding of whole exemplars. Results support an…

Steinman, Bernard A.; Kimbrough, B. T.; Johnson, Franklin; LeJeune, B. J. – RE:view: Rehabilitation Education for Blindness and Visual Impairment, 2004
The enormously complex and sometimes controversial project to unify the traditional literary Braille code used in English-speaking countries with the technical and mathematical codes authorized by the Braille Authority of North America (BANA) and the Braille Authority of the United Kingdom (BAUK) proposes to change English Grade Two Braille on a…

Middendorf, Joan; Pace, David – New Directions for Teaching and Learning, 2004
Using the Decoding the Disciplines model, faculty who are deeply ingrained in their disciplinary research answer a series of questions to understand how students think and learn in their field. The cross-disciplinary nature of the process clarifies the thinking for each discipline. (Contains 1 figure.)

Sullivan, Megan – Science Teacher, 2005
For the general public, the field of cryptography has recently become famous as the method used to uncover secrets in Dan Brown's fictional bestseller, The Da Vinci Code. But the science of cryptography has been popular for centuries--secret hieroglyphics discovered in Egypt suggest that code-making dates back almost 4,000 years. In today's…
