Five experiments involving children of 4-11 years investigated partonomic knowledge and its relation to the use of taxonomic organization. Results suggest that children are sensitive to parts of common objects and appear to be able to use this sensitivity to group objects in abstract, function-based, superordinate categories. (RJC)

Provides a historical review of copymarking, a conceptual description of various types of copymarks, and a taxonomy of copymarks used in electronic conversion systems. Issues raised by the development of document interchange standards and conversion systems are reviewed, and implications for future research on documents and document processing are…

Investigates the knowledge of thematic and taxonomic relations of 15 children of 26 months and 24 children of 34 months. Both age groups were able to identify thematic matches. However, 34-month-olds were able to recognize a wider range of thematic associations than 26-month-olds. (RJC)

Discusses the need to retrieve ideas in addition to content retrieval by such means as classification, subject headings, and keywords. Three models for idea retrieval are described, and a new model is proposed which combines selection, a controlled vocabulary, and logical structure. (seven references) (CLB)

Explains seven types of subject descriptions commonly used in databases--hierarchical classification, category codes, subject headings, descriptors, faceted classification, post-controlled vocabulary, and natural language--and describes specific search techniques for taking advantage of the strengths of particular types of vocabularies. An overall…

Claims that authors of a November 1988 "Kappan" article on special education are conducting a campaign to change special education in their own image. Asserts that special and regular education are interwoven, not separate or segregated, processes and that support teams are designed to help teachers improve student learning and behavior in the…

Review of the 1987 subject access literature covers: (1) general works; (2) organization, history, theory, and method of classification; (3) classification systems; (4) subject headings and the Library of Congress; (5) subject authority control through the Library of Congress Subject Headings; (6) subject searching in online catalogs; and (7)…

Three experiments using the familiarization-novelty preference procedure confirmed the hypothesis that three-month-old infants could form categorical representations of spatial relations above and below. The infants, after being shown a familiarization diagram with a dot appearing in multiple locations below a line, showed a preference for a novel…

Three experiments involving 128 infants studied whether and how novel words influence object categorization in 12- to 13- month-old infants. Data revealed that a linkage between words and object categories emerged early enough to be a guide in infants' efforts to map word meanings. (SLD)

Using the original validation sample for the Halstead-Reitan Neuropsychological Battery, a discriminant function analysis was performed to determine the best set of weights for the measures in its Impairment Index. Findings suggest that an empirically derived set of weights is probably no more useful than equal weighting commonly used. (SLD)

Describes a new data compression technique that utilizes the common morphological structure of languages. Topics include classification of languages and their morphological structure; structured text compression; the algorithm and an example using Turkish; theoretical implications; and implementation. (LRW)

Fifty-two undergraduates completed a questionnaire identifying 40 acquaintances, from which 4 were picked systematically from the list. Role descriptions for the four acquaintances, ratings of their relationships, and characteristics of the relationships were assessed. Found evidence for the existence of truly discrete cognitive forms of social…

Three experiments compared the assignment of gender to masculine and feminine pictured objects as classified by Spanish grammatical gender, by English- and Spanish-speaking children, and by adults. Results revealed artificial-male/natural female conceptual division among speakers of English and delayed effects of grammatical gender among speakers…

Describes investigation utilizing sickle cell disease subjects from a stress and coping project. Found little stability in classification of individuals' adjustment, low congruence in behavior problem patterns and diagnoses, and less stability in adjustment by child report than mother report. Suggests children's coping strategies are intervention…

Factors affecting the development of a taxonomy of psychopathology for children with mental retardation are considered, along with the following diagnostic areas to address: stereotypic behavior and self-injury, autism, organic brain syndromes, and pervasive developmental disorders. Using data from multivariate studies and findings related to…
