Three experiments examine how preschoolers partition their basic level categories to form subordinate level categories and whether these have inductive potential. Results suggest that contrastive information promotes the emergence of subordinate categories as a basis of inductive inference and newly established subordinate categories can retain…

Trial-by-trial strategy assessments and a microgenetic design were used to examine the learning of rules for solving balance scale problems by 70 4- and 70 5-year olds. Developmental differences in learning that emerged seemed to reflect both distal and proximal influences. Encoding and initial rule use were related to different learning process…

Respondents' Bem Sex-Role Inventory (BSRI) classifications may differ considerably on the basis of the form and scoring method used. The BSRI was reexamined with respect to past and present relevance. (Contains 62 references and 3 tables.) (Author)

Includes "Seven Key Issues for Management Development" (Paauwe, Williams); "Typology of Management Development" (Jansen, van der Velde, Mul); "Management Development at Royal Dutch/Shell" (Mahieu); "Management Development in Unilever" (Reitsma); "International Co-ordination and Management…

Uses data concerning all young sex offenders (N=56) to construct and validate an introductory young sex offender typology based solely on offense characteristics. A 5-cluster solution received optimal support from cluster analysis of 15 offense-related variables. Survival analysis revealed that the clusters differed with respect to sexual but not…

Two studies explored one university's application of learner-type segmentation to enable a better understanding of its undergraduate students. Tested the hypothesized segments of "job focused,""knowledge seeker,""socio-economic advantage,""stepper," and "undecided" through surveys and focus groups.…

Four experiments investigated 3-year-olds' understanding of the differential importance of shape for categorizing solid objects. Found that they categorized rigid and deformable objects differently in a non-naming task and knew that material was important for deformable items and shape for rigid items. In two naming tasks, they generalized names…

Investigated whether Brazilian 4-year-olds held essentialist beliefs about animal categories. Found that middle class and poor children were equally likely to interpret labels as referring to mutually exclusive animal categories, and more likely to accept a common label for animals sharing internal properties than superficial properties,…

Defines dichotomous keys as common learning tools based on identification rather than memorization. Provides an example of a dichotomous key developed for introducing histology in human anatomy and physiology (A&P) courses and explains how students can use the dichotomous key. Discusses the goals of the exercises and the process of…

This study compared four systems for diagnosis of autism (Diagnostic and Statistical Manuals of Mental Disorders III, III-R, and IV, and the International Classification of Disabilities-10) with 2 empirically derived taxa and 3 social subgroups (aloof, passive, and active but odd) in 194 preschool children with social impairment. Findings support…

A classification system for risk communication can serve two major purposes: it provides a practical guide to techniques and establishes a framework for further development. By using traditional models of communication elements and management operations, this taxonomy has the advantage of being more readily adapted to the needs of environmental…

People categorize items and concepts according to a prototypical image they build in their mind of what it is that represents the particular item or concept in question. The article argues that the notion of prototypicality has important implications for a discussion of genre. (35 references) (Author/CK)

The validity of intuitive classifications of experienced diagnosticians was examined for 10 experienced diagnosticians evaluating child behavior problems. Results showed that intuitive prototypes corresponded poorly with empirical core syndromes in the assessment system of T. M. Achenbach and others. Reasons for differences are discussed. (SLD)

Presents a brief review of the research on workaholism and the family and offers a typology of workaholism that more adequately portrays the various work styles of workaholics. This typology, based on level of work initiation and completion, denotes 4 types of workaholics: relentless, bulimic, attention-deficit, and savoring. (Contains 18…

Analyzes responses to the College Student Experiences Questionnaire from 51,155 undergraduates at 128 institutions to develop a student typology based upon their patterns of engagement in educationally purposeful activities and the progress they reported making toward important outcomes of college. The typology reported yields new insights into…
