Three experiments tested 3-year-olds' subordinate classification. The first experiment found that novel noun presentation hindered classification. The second and third experiments found that provision of information for the purpose of distinguishing relevant subclasses, and introduction of novel nouns in conjunction with familiar basic level…

Reports the results of a content analysis of research in library and information science based on articles in international journals. The classification scheme used to classify article topics is explained, the distribution of research articles and professional articles is compared, data collection methods are discussed, and research strategies are…

Classification accuracies of models for predicting later high school dropouts from data available in student records for grades 4 through 8 were examined for 503 dropouts and 282 persisters (nondropouts) in Florida. Separate prediction models for each grade level have practical importance; implications for dropout prediction are discussed. (SLD)

A sample of 175 maltreated children (mean age 51.9 months), 39 children in mental health treatment, and 176 normative children was assessed for type and severity of maltreatment. Results showed that psychological maltreatment was present in almost all cases of physical maltreatment and was more related to detrimental child outcome than was…

A study analyzed relationships of 7 institutional characteristics and 5 fund-raising outcomes over 605 institutions in 10 types. Statistical analysis was used to describe how relationships of characteristics and outcomes vary by institution type and specific donor and to identify institutions with effective fund-raising programs based on…

A study involving elementary school students in three age groups examined two explanations for the finding that young children tend to classify objects according to similarity relations, whereas adults emphasize dimensional structure. Results countered the view that children perceive objects according to a more primitive holistic structure. (RH)

In response to Larry Silver (EC 231 774) concerning whether attention deficit-hyperactivity disorder is a learning disability via a related disorder, this article proposes an interactional perspective that stresses the educational needs of the child within his/her total environmental context. It also summarizes the current empirical and clinical…

This paper discusses studies of visual dyslexia, the nature of visual processes involved in word recognition, and the contribution of visual memory to word recognition. The paper concludes that, though defects in the physiological aspects of visual processing can lead to reading difficulties, evidence does not indicate the existence of visual…

This article presents an overview of literature relating to a nonverbal learning disabilities subtype. The article addresses the relationship between nonverbal learning disabilities and socioemotional functioning, generalizability of research outcomes, individual differences, and treatment validity. (Author/JDD)

Examination of the role of psychometrics in the development of multiple-choice tests and performance-based assessments and consideration of validity and reliability issues leads to this conclusion: Choice of assessments for instruction or large-scale accountability depends on which is more appropriate for the particular purposes. Taxonomic…

Reviews trends in social work assessment that are likely to shape future of clinical practice. Contends that, in contrast to rich contextual information provided by traditional psychosocial approaches to assessment, classification systems like Diagnostic and Statistical Manual of Mental Disorders (Third Edition, Revised) can lead to…

This paper examines the extent to which the 1992 American Association on Mental Retardation (AAMR) definition of mental retardation provides decision rules to guide clinicians and researchers in classification efforts. The paper examines concerns about the intelligence quotient criterion, the adaptive skill areas, and proposed differentiation by…

Describes a project to help students shift from the precision they expect in science to the more ambiguous nature of taxonomy. Students are asked to project themselves 500 years into the future when, as a result of humankind's pollution, there are only 10 remaining organisms. Some organisms are unlike any previously known. Students name and…

In their book entitled Scientific Knowledge, Barry Barnes, David Bloor, and John Henry repudiate the notion that physical environment plays no role in the creation of scientific knowledge, thereby removing a major bone of contention between scientists and practitioners of the sociology of scientific knowledge. A physicist discusses ways in which…

Examines some medical classification systems with a long history--notably the "International Classification of Diseases (ICD)." States that this classification scheme retains many traces of its own administrative and organizational past in its current form. Suggests that ICD, like other large-scale classification systems, performs so…
