Three experiments tested a model identifying object labels as discrete attributes of the object in which the relative weight of the label decreases with children's age. Results indicated that labels contribute to similarity judgment in a quantifiable manner, labels' weight decreased with age, and effects of labels were likely to stem from the…

Presents a morphological classification of languages from the information retrieval (IR) perspective. Discusses differences in inflection, derivation, and compounding; index of synthesis and index of fusion; cross-language retrieval research; the need for semantic and syntactic typologies; and the effects of morphology and stemming in IR.…

Discusses the shift in the organization and classification of knowledge as a result of the World Wide Web and considers implications for the liberal arts and education in the liberal arts. Highlights include the postmodern period and the obsolescence of knowledge hierarchies; and personal meaning schemes. (LRW)

Sidman's (2000) theory regarding the origin of equivalence relations predicts that a reinforcing stimulus common to distinct equivalence classes must drop out of the equivalence relations. This prediction was tested in the present study by arranging class-specific reinforcers, R1 and R2, following correct responding on the prerequisite conditional…

We document a typology of perfectionism in a sample of academically talented adolescents and directly examine its relationship to indices of psychiatric symptomatology, adjustment, self-esteem, and coping. Adolescents enrolled in a state-funded residential academy for academically gifted high school students (N = 141) responded to the…

More often than not, metafiction is approached more on philosophical than aesthetic grounds. In metafictional works the ontological or epistemological dimensions of works of art, literature in particular, are being highlighted by the art works themselves. Moreover, metafictional works of art are singled out as a specific type, almost a genre. This…

Course developers can be distracted from applying sound instructional design principles by the amount of flexibility offered through online course development resources (Kidney & Puckett, "Quarterly Review of Distance Education," 4 (2003), 203-212). Distance education course management systems (CMS) provide multiple features that can be easily…

Existing estimates of the prevalence of intellectual disability vary substantially between different studies and among different populations (AIHW: Wen, 1997; Roeleveld, Zielhuis, & Gabreels, 1997; Leonard & Wen, 2002), often affected by differences in operational definitions and methods of estimation. For example, in Australia, operational…

This paper reviews an ongoing debate about moral standards for vocational education in German speaking countries. At the centre of the controversy is the question of universalistic versus domain-specific moral orientations, namely the question of whether business people ought to develop different moral points of view in different situations (such…

Sometimes the questions that art poses and the paths taken to answer them can be as important as the answers themselves. Questions in aesthetics--the branch of art that deals with philosophical issues--involve exploration of big ideas that have varied and multiple responses. Providing opportunities for students to consider and reflect upon their…

Biological classification embodies the most fundamental idea in all of biology, especially evolution. The contrast between biological classifications and those of manufactured objects for instance hardware-based collection of screws, nails and bolts, help illustrate the central biological ideas and induce student interest, however, this could be…

A brief history is given of approaches that aim at achieving a connectedness of the content of organic chemistry courses to real world issues. Recently, such approaches have relied more and more on online media resources, the tools of the Internet and the World Wide Web. We propose a six-level taxonomy of 'authentic news media-based learning…

In two experiments, we examined the role of labels in guiding preschoolers' extension of three types of familiar adjectives: emotional state adjectives, physiological state adjectives, and trait adjectives. On each trial, we labeled a target animal with one of the three different types of adjectives and asked whether these terms could apply to a…

The authors conducted 3 experiments addressing the issue of how observations and multiple sources of prior knowledge are put together in category learning. In Experiments 1 and 2, learning was faster for critical features, which were predictable on the basis of prior knowledge, than for filler features, and this advantage increased as more…

Disentangling bottom-up and top-down processing in adult category learning is notoriously difficult. Studying category learning in infancy provides a simple way of exploring category learning while minimizing the contribution of top-down information. Three- to 4-month-old infants presented with cat or dog images will form a perceptual category…
