Notes that the hobby of collecting is a way families can reinforce and expand a child's learning when not in school by encouraging development of classification, categorizing, and decision-making skills. Describes resources on and what can be learned by collecting rocks, seashells, cards, and stamps. (DR)

This paper reviews 20 studies that investigated the internal or external validity of various subtypes of autistic spectrum disorders. At least three groups could be distinguished from autism on clinical grounds: an Asperger syndrome subtype, and two atypical subtypes characterized by either low intelligence quotient or high intelligence quotient.…

Defines a fuzzy retrieval model as the basis for extending a weighted Boolean information retrieval system in which numeric query weights are replaced by linguistic descriptors that specify the degree of importance of the terms. A relevance classification process is described, and implementation and evaluation of the fuzzy retrieval model is…

Adults and five and seven year olds were presented with slides of facial expressions with different parts of faces exposed. Subjects judged either discrete emotions of happiness, surprise, fear, and anger or global emotions of feeling good and bad. Subjects more easily recognized global than discrete emotions. (BC)

Developed typology of college students using dating violence. Findings from 97 females and 69 males who expressed violence toward their partners identified 4 subgroups of students who differed in their use of coping and negotiation strategies, in their feelings of love and ambivalence, in their experience of conflict and violence, and in their…

A framework is presented to document the process of category development. This two-dimensional model designed to facilitate the documentation of procedures used to generate categories specifies components associated with the development of categories and addresses the temporal aspects of category development. A study of preservice teachers…

High point profile analysis of scores from the General Occupational Theme scale of the Strong Vocational Interest Blank-Strong Campbell Interest Inventory and the General Aptitude Test Battery for 516 males and 330 females indicated that interests correlated with high abilities. A theoretically coherent typology of individuals' vocational…

The ability of six-month-old infants to remember a functional category acquired in a specific context was assessed in three experiments. Findings revealed that at six months, information about the place where categories are constructed is prerequisite for retrieval of a category concept from long-term memory. (GLR)

Classifies explicit verbal comparisons in 53 popular children's books both syntactically and semantically. Comparison types found in these books were contrasted with comparisons used as comprehension stimuli in extant developmental research. Implications for the design of future stimulus sets are discussed. (17 references) (GLR)

Presents critical analysis of a paper "Testing Reading Comprehension Skills, Part One," in which the consideration concerns the inadequacy of taxonomies of skills to describe individual readers' processes and, hence, their usefulness in test construction. (15 references) (GLR)

An investigation was conducted of the displayed biobehavioral states of 5 students (ages 8-20) with profound mental retardation. Results indicated that state level can be reliably specified and that overall state characteristics can be used to classify subjects according to profile groups. (Author/JDD)

This response to Stanovich's (EC 607 092) proposal of a new type of learning disability, dysrationalia, looks at implications for the entire learning disabilities field, especially increasing differences between operational and substantive definitions and the ongoing creation of new types of learning disabilities to overcome perceived definitional…

Emotional characteristics of gifted children are examined. Frameworks developed by G. Betts and M. Neihart and by A. Roeper, which classify children by features of their characteristic emotional response, are described. Gifted children's unusual levels of sensitivity and intensity are noted and illustrated with a case example. (JDD)

Capitalizes on students' interest in driving by using road signs, which are classified by shape as well as by color, to teach about geometric shapes. (HTH)

This article describes the strengths and weaknesses of different models of classification (primarily monothetic and polythetic) and then focuses on cluster analysis as a method of pursuing a polythetic model. Design features that need to be incorporated in a cluster analytic study are discussed in relation to theory formulation, internal validity,…
