The article examines the role of drug treatment stressing the need to treat disorders of brain function rather than direct behavior control. Treatment principles concern classification, dosage, monitoring effects, timing of therapy, the distinction between passive and active disorders as well as syndromal, manipulative, ritualistic, cyclothymic,…

In two studies, preschoolers and second graders were tested on their understanding that members of a category have similar parts. Children in both studies drew many inferences concerning the internal structure of objects in basic-level categories. Suggests that preschool children assume that basic-level categories share internal parts. (RJC)

Six studies, with 174 three-year-olds in California, investigated whether children's knowledge of a label for an object excluded the possibility that they would accept another label for the object. Results indicate that mutual exclusivity motivates children to learn terms for attributes, substances, parts, and objects. (TJH)

Presents a mathematical theory that can be used to define concentration places of objects within unordered classes. The application to research on the evolution of journals and subject areas is illustrated, and an online method of calculating concentration evolution is described. (1 references) (CLB)

Systems theories of personality often describe subsystems (such as conscious and unconscious) and subsubsystems (such as ego, id, and superego). This paper classifies the major systems theories of personality in terms of the number of levels in their analysis. (Author)

A discussion of the development of critical-mindedness through science education looks at scientific attitudes and the stereotype of the objective, detached scientist. It argues that critical-mindedness depends on cognitive and affective inputs as well as critical thinking ability and proposes a concept of scientific critical-mindedness and…

This review of the 1986 literature on subject access covers: (1) general works; (2) organization and history; (3) classification systems; (4) classification theory and method; (5) Library of Congress Subject Headings (LCSH); (6) authority control through LCSH; (7) subject searching through LC-based, assigned subject headings; and (8) other subject…

The role of staff development in establishing charactertistics of an effective school was examined in order to illuminate associations. A framework was used to categorize these characteristics into three critical dimensions. Two consistent patterns emerged that are described and used to present broad guidelines for the conduct of staff…

Changes in children's categorization behavior between 15 and 21 months of age and the relation of these changes to developments in language, object permanence, and means-end understanding are reported. (PCB)

The processes by which Roe (1956) and Holland (1966) developed their structural representations of occupations are compared. Roe, using almost exclusively nonempirical means, formulated an eight-group circumplex, virtually identical to Holland's six-group hexagonal configuration that resulted from empirical research spanning 11 years. The…

Problems in teaching French verb conjugation are traced to problems in morphological classification systems, and a new, descriptive approach using seven criteria is described and illustrated. (MSE)

This second validation study of the Parent Opinion Questionnaire (POQ) compared the unrealistic expectations of child abusing mothers (N=16) with mothers whose partners perpetrated the abuse (N=14). Significantly greater unrealistic expectations of child behavior were found for abusing mothers than for control mothers. A discriminant function…

The paper on learning disability (LD) definition and subtypes considers the nature of the definition and differentiation problems, the importance of placing and keeping LD in perspective vis a vis other learning problems, and future development of a LD classification schema using dimensions of cause, severity, pervasiveness, and chronicity.…

The paper identifies areas of agreement among leaders in learning disabilities (LD) including heterogeneity of the LD population; explores the classification problem as it relates to etiology and/or treatment, and proposes a five-step plan to influence public policy concerned with differentiation and treatment of different types of learning…

Delineates various levels of theory with implications for research in library and information science. Based upon a review of literature on theory building and research methods in the social sciences, a model is proposed which displays a taxonomy of theory in hierarchical form. (EM)
