Two experiments examined the development of recall organization by observing use of categorical and spatial clustering strategies and how encoding experiences and recall task influence degree of organization. Children and adults recalled furniture from their home. Older subjects organized items spatially; when recalling objects and their…

Summarizes the revised economic and policy types of the Economic Research Service's rural county classification system. The new typology is based on conditions in more recent years, includes Alaska and Hawaii, redefines persistent poverty, includes more county types, makes economic types nonoverlapping, and classifies counties designated as…

Presented a categorization of types of science education research, their possible contributions to cognitive science, and the potential of results from cognitive science for enriching the science education research accounts. Explored the relationship of an example of cognitive work to cognitive science. (15 references) (Author/JRH)

Proposes an instructional transaction class hierarchy and describes capability, knowledge, interactions, and associated transactions for three classes of transactions: (1) component transactions (identify, execute, and interpret); (2) abstraction transactions (judge, classify, decide, generalize, and transfer); and (3) association transactions…

This paper compared clinicians' diagnosis and DSM-III (Diagnostic and Statistical Manual), DSM-III-R (Revised), and ICD-10 (International Classification of Diseases) diagnoses of 52 individuals with autism and 62 nonautistic, developmentally disordered individuals. The DSM-III-R system overdiagnosed the presence of autism, and ICD-10 closely…

A typology of physically abusive parents was developed based upon personality characteristics measured by the Sixteen Personality Factor Questionnaire. Cluster analysis revealed five distinct patterns, with differences among clusters in age, education, number of children, number of parents involved in abuse, and other variables. Possible treatment…

Discusses a study in progress that is analyzing retrieval failures in two full-text computer-assisted legal research (CALR) systems, LEXIS and WESTLAW. Computer searching by experts is compared with manual searching by experts, examples are given, and a taxonomy of causes of retrieval failure is discussed. (13 references) (LRW)

Compared children's cognitive abilities at four years and their prenatal amniotic fluid testosterone levels. For girls, prenatal testosterone levels were related in a curvilinear manner to language comprehension and classification abilities, and inversely related to counting and knowledge of number facts. For boys, no relationships were found. (BC)

Seventeen preschool children, 26 kindergarten, and 26 fourth grade childrens' knowledge structures were examined with a word association task and a match-to-sample picture task to determine whether or not children used slot-filler categories as a mediating structure between event-based and taxonomic knowledge structures as proposed by Nelson…

Presents a framework used at Western State College to teach an interdisciplinary general education course. The framework helps students organize a large volume of material about Contemporary World Cultures according to a taxonomy of human experience, including artistic/literary expression; thought and belief; relationships/associations with…

Four experiments determined that kindergartners' and second graders' inductions are sensitive to the similarity between premise and conclusion categories. Second graders' inductions are sensitive to the similarity of a premise category to a higher order category that includes the premise and conclusion categories. (BC)

Twelve two year olds were taught novel count nouns for related but unfamiliar objects. Children's interpretation of the relations between the nouns was mediated by the similarity of the objects, a result that suggests that, by age two, children have the conceptual and lexical abilities necessary for establishing hierarchical relations.

A participatory model in evaluation is presented as an extension of the stakeholder-based model focusing on the increased participation of primary users. Twenty-six empirical studies that support an organizational learning justification of the model are reviewed and classified. Requirements for participatory evaluation are discussed. (SLD)

Analyzes attributes of symbols and identifies the need for a suitable management system for retrieving images from a database. A classification structure that incorporates graphic, semantic, and bibliographic dimensions is described; experiments with describing, sorting, and drawing symbols are reviewed; and future work on a database management…

Utterances from stuttering and normally speaking children, aged two through four years, were analyzed by clinicians specializing in stuttering, general clinicians, and university students (total n=25). Results indicated that the validity of the data language used by researchers to describe stuttered and normal speech in early childhood may be…
