The territoriality and aggression of 25 profoundly retarded institutionalized adult males were measured in an examination of potential grouping procedures. (CL)

Evaluation of classification skills of 88 unimpaired children (grades K, 2, 4, and 6) were evaluated using the Iconic-Symbolic test (IS) of the Muma Assessment Program and follow-up interviews. Results found little relationship between the rationales the children reported using and the classification criteria presumed by the IS procedure. (DB)

A 20-item Piagetian-type sorting task was presented to 12 unilaterally brain-injured adult patients and 12 non-injured controls. The left hemisphere brain-injured subjects and the controls showed preferences for the features of shape and texture. In contrast, the right hemisphere brain-injured subjects preferred the feature of size. (Author)

Establishes two categories of numbers: (1) relatively frequent numbers and (2) relatively infrequent numbers. The numbers in the first group are manipulated by people and depend, at least to some degree, on memorization; those in the second group are essentially machine inputs. Examples of the first group are examined. (SED)

Describes features of Bliss Bibliographic Classification (BC2) that make it thesaurus-compatible and a source for thesaurus compilers: facet analysis, terminology source, thesaural relationship source, and updating ease. Problems with using BC2 as a thesaurus source are also considered, and two thesauri based on BC2 are described. (MBR)

The study compares public sector and private sector comparable worth litigation. Findings suggest that private sector organizations use the job classification method less than public sector employers in the litigated cases. Pay and promotion were focal points in public cases; lack of training opportunities was more prevalent in the private sector.…

Assessment of category knowledge and receptive language skills of 16 autistic (3-6 years old), mentally retarded, and normal children indicated that the autistic children's knowledge of function, form, and color categories was comparable to that of the mental-age-matched mentally retarded and normal comparison groups. (Author/DB)

Reviews the problems of classifying gaming techniques and suggests a heuristic approach as one solution. Definitions of simulation, models, role, and game and play are discussed to help develop a classification based on a technique called gaming simulation. (Author/LRW)

Examines geriatric health teams, discussing four dimensions of models for professional functioning (logic of assessment, focus of efforts, locus of responsibility, and pace of action) and three dimensions of models for team functioning (focus of attention, decision-making style, and beliefs about interprofessional dependence). (Author/NB)

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)
