Studied a new approach, based on Rasch model item response theory, to age equivalence scores as a basis for mental age and the calculation of ratio IQ. Results for 1,719 children and adolescents suggest that the new ratio IQ had consistent criterion and construct-related validity at the same level as standard-score IQ. (SLD)

This study investigated whether deafness contributes to enhancement of visual spatial cognition, independent of knowledge of sign language. Comparison of 12 congenitally deaf children not exposed to sign language and 12 matched hearing controls found that the groups did not differ in their performance on visual spatial skills tests.

Discusses principles of learning and instructional theories and relates them to instruction in academic library user education. Highlights include a conceptual approach, Gagne's hierarchical knowledge and instructional design, Merrill's instructional theory, Reigeluth's elaboration theory, Kolb's experiential learning, Perry's cognitive…

Examined age and gender differences regarding the nature, meaning, and function of cherished possessions. Among the significant differences found were that younger children were egocentric in meanings assigned to cherished possessions, whereas older children held social relationships meaningful; females favored items to be contemplated, while…

Explored four- to six-year olds' approach to drawing and related writing tasks. Participants, unschooled in writing, were asked to depict common objects with a drawing and a written name. Analysis of videotape revealed systematic differences (random, continuous marks versus discrete, left-to-right marks). Results suggest that young children have…

This study attempts to rebut criticisms of the developmental theories of Jean Piaget by showing that most criticisms derive from misinterpretation and forget the dialectical, constructivist, and developmental nature of Piaget's work. Important aspects of Piaget's theory have not been assimilated by developmental psychologists. (SLD)

In response to a previous article (Bialystok) on perspectives on the development of applied linguistics, this article begins by adding its own perspectives to what has already been offered. The article concludes by discussing the research agenda for the future. (Author/JL)

Four studies examined the influence of essentialist information such as internal properties and perceptual similarity on 3-, 4-, and 5-year olds' interpretations of labels. Results suggested that children have essentialist beliefs about animals, but not about artifacts, and that these beliefs interact with children's assumptions about word meaning…

Maintains that Muller and Overton (1998) misrepresent her theory of infant concept formation in infancy, makes corrections to their representation, and notes that her theory was developed in part because of the lack of detailed mechanisms in Piaget's theory to account for concept formation. Argues that Muller and Overton's proposed alternative…

Presents a study in which participants were trained on nine single-digit multiplication problems over three sessions. Transfer of practice was tested with nine different multiplication problems in the fourth session for half the participants. Interprets problem-size, transfer, and retention effects within a network-interference model of mental…

Discusses the four planes of development and the periods of creation and crystallization within each plane. Identifies the type of independence that should be achieved by the end of the first two planes of development. Maintains that it is through individual work on the environment that one achieves independence. (KB)

Discusses the links between emotional development and pretend play in young children using basic foundations of psychoanalytic and learning theories. Explains emotional development and pretend play through interactive levels of expression, control and modeling of emotion, and emotional intelligence. (JPB)

Research emphasizes the impact of service learning on college students' development. Less evidence exists of its cognitive impact. To improve academic learning quality, researchers must identify intellectual outcomes best facilitated through service learning, create measures of these outcomes to embed into instructional processes, and conduct…

Focuses on the conceptual implications of analyses of individual differences in francophone post-Piagetian research. Maintains that these analyses are preoccupied by the "American question" of measurement and method, instead of attempting a theoretical account of the issues raised by intraindividual and interindividual variability in…

Examines results and interpretations from recent books, journal articles, policy studies, and media stories on how the emerging understanding of brain development and neural function could revolutionize educational practice, focusing on: the neuroscience and education argument; synaptogenesis; critical developmental periods; enriched environments…
