Six experiments examined how children approach the task of learning novel count nouns. Findings indicated that three- and four-year olds function with an antithematic bias and that children do not reliably extend novel count nouns to subordinate exemplars when perceptual similarity is controlled until about age 7. (MDM)

Twenty-two children (ages 5-8) with mild mental retardation who received learning set instruction on unidimensional classification and seriation improved on these precursors to concrete operations; 22 children who received more conventional instruction did not. Improvement on classification and seriation was accompanied by improvement on measures…

A study concerned with factors that may affect three-year olds' acquisition of subordinate categories considered salience of the attribute or attributes that differentiate a subordinate category, presence or absence of linguistic input, and child characteristics. Correlational analyses pointed to a series of relationships between child…

In a cost-effective way to assess training benefits, replies to open-ended questions are analyzed for patterns, and common themes are grouped hierarchically. Trainees perceived benefits in terms of improved professional skills; their managers stressed personal and attitudinal changes in trainees. (SK)

A method is presented for estimating the accuracy and consistency of classifications based on test scores. The reliability of the score is used to estimate effective test length in terms of discrete items. The true-score distribution is estimated by fitting a four-parameter beta model. (SLD)

Three studies investigated the influence of principle-based inferences and unprincipled similarity relations on new category learning by three- to six-year-old children. Results indicated that categorization into newly learned categories may activate self-initiated, principle-based reasoning in young children, suggesting that spontaneous…

This study compared DSM-III-R (Diagnostic and Statistical Manual III, Revised), Childhood Autism Rating Scale, and clinical diagnoses of 138 admissions to a program for diagnosis and treatment of autistic and related communication-handicapped individuals. Results indicated generally high agreement on the diagnosis of autism, with DSM-III-R…

This paper assesses to what extent the ICD-10 (International Classification of Diseases) criteria differ from other diagnostic systems for Asperger syndrome. The paper concludes that the variety of criteria in use makes interpretation of research findings difficult and that the ICD-10 criteria are the most stringent and closest to Hans Asperger's…

Identifies deficiencies in reference services offered by archives and examines factors preventing effective use of archival resources, including changing clientele, organization of collections based on the principle of provenance, and the uniqueness of archival collections. Suggestions for improving public service, including user studies and…

Three experiments investigated the ability of 79 college students to solve similar algebra word problems. Data indicate that students are able to perceive and use similarities in such problems at the level of a conceptual structure. A training session to explain relevant structural principles was effective in improving performance. (SLD)

Discusses skills development and presents a matrix that combines two skills classifications: closed and open skills, and discrete and continuous skills. Examples of each type of skill are given, implications for instructional design are considered, and the creation of a museum of examples of open-skilled products and performances for instructional…

This study assessed the nonspeech behaviors associated with young stutterers (n=30, mean age 54 months) and normally fluent children's comparable fluent utterances. Findings suggested that children can be classified as stutterers on the basis of their nonspeech behaviors, which may reflect cognitive, emotional, linguistic, and physical events…

Investigated stability of sociometric classification system. Found that, among 137 students in kindergarten through grade 4, scores upon which sociometric classifications were based were moderately stable, but sociometric status was unstable over 1-year interval. Reclassification rates for extreme groups (rejected, neglected, controversial,…

Discusses the history of information science and its understanding of and approach to relevance; explains human categorization theory and applies it to the idea of relevance; shows that information science research is flawed because it fails to adequately explain experience; and suggests implications for future research.

Offers several strategies for implementing cooperative learning in the classroom. Suggests sample exercises including (1) a scavenger hunt; (2) a reaction wheel; (3) cooperative brainstorming and classification; (4) a "pair of pairs" exercise; and (5) a three-step interview. Explains that the examples are starting points that have been used in…
