This paper proposes that patterns of proximity data that have been characterized in terms of asymmetric similarity may be alternatively characterized in terms of differential bias. An additive similarity and bias model is reviewed, and it is proposed that biases can be stimulus based as well as response based. (SLD)

Discusses problems of general interest in developmental psychology that can be successfully studied in the domain of food; these include (1) development of food likes and dislikes; (2) establishment of the edible/inedible distinction; (3) disgust and contagion; (4) transgenerational communication of preferences; and (5) transition to food…

To begin formal thinking skills instruction teachers need a plan which consists of a taxonomy of skills, a timetable, and effective teaching techniques. This article presents a condensed version of an existing in-place taxonomy and a scope and sequence timetable which can serve as a guideline for teachers. (IAH)

Describes characteristics of experimental predictor battery of tests developed to supplement the Armed Forces Vocational Aptitude Battery for making selection and classification decisions for entry-level enlisted personnel. Explains procedures used to develop new test battery. Basic psychometric properties of each measure, as determine by large…

Used data from 4,039 job incumbents from 9 military jobs to determine degree of validity generalization across major components of performance and degree of validity generalization across jobs within each major performance factor. Major findings were that different predictor equations were needed for each of 5 criterion factors. (Author/NB)

In 5 experiments, 10 month olds were habituated to exemplars of a form category and tested for categorization in paired-comparison trials involving in-category versus out-of-category stimuli. Results suggest infants' internal representation for category will not include stimulus dimension not varied in exemplars from which the category was…

Taxonomies are unavoidably infused with recommendations of what ought or ought not to be. Thus, use of descriptive taxonomies may have a normatively conservative effect independent of user intentions. The importance of taxonomies to adult education necessitates a critical understanding of their normative features. (SK)

Proposes a taxonomy of moral values to be used by researchers in developing unbiased instruments for assessing the nature of people's moral reasoning. Discusses six ways of defining "moral" and selects one as a means of illustrating the use of the proposed taxonomy in constructing such an instrument. (KO)

The mechanisms of both language-based and non-language-based learning disabilities are presented within the framework of central nervous system development and the compromises to that development that arise from genetic, hormonal, antibody, medication, and postnatal compromises. Also reviewed is the need for a taxonomy of learning disabilities.…

Investigation into the relative effectiveness of four input strategies for two-year-olds' (N=56) category evolution found that the most effective strategy involved labelling an object and providing both a physical demonstration and a verbal description of important attributes. (Author/CB)

Five experiments involving children of 4-11 years investigated partonomic knowledge and its relation to the use of taxonomic organization. Results suggest that children are sensitive to parts of common objects and appear to be able to use this sensitivity to group objects in abstract, function-based, superordinate categories. (RJC)

Provides a historical review of copymarking, a conceptual description of various types of copymarks, and a taxonomy of copymarks used in electronic conversion systems. Issues raised by the development of document interchange standards and conversion systems are reviewed, and implications for future research on documents and document processing are…

Investigates the knowledge of thematic and taxonomic relations of 15 children of 26 months and 24 children of 34 months. Both age groups were able to identify thematic matches. However, 34-month-olds were able to recognize a wider range of thematic associations than 26-month-olds. (RJC)

Discusses the need to retrieve ideas in addition to content retrieval by such means as classification, subject headings, and keywords. Three models for idea retrieval are described, and a new model is proposed which combines selection, a controlled vocabulary, and logical structure. (seven references) (CLB)

Explains seven types of subject descriptions commonly used in databases--hierarchical classification, category codes, subject headings, descriptors, faceted classification, post-controlled vocabulary, and natural language--and describes specific search techniques for taking advantage of the strengths of particular types of vocabularies. An overall…
