Reports on connectionist models that simulated the formation of global-level and basic-level representations in young infants; revealed a global-to-basic order of category emergence; uncovered formation of two global-level representations--initial "self-organizing" perceptual level and subsequent "trained," non-perceptual…

Tested a knowledge-based view of early memory development. Assessed preschool children's knowledge about two different scenes and their recall and location memory for objects in those scenes. Found that age, knowledge about categories, and memory for unrelated objects were significant predictors of memory of objects in the scenes. (MM)

Examines the nature of prior mathematical knowledge that facilitates the construction of useful problem representations in the domain of geometry. Indicates that high achievers build schemas that are qualitatively more sophisticated than low achievers, which in turn helps them construct representations that are conducive to understanding the…

Adapted Keil's predictability method to examine adults' and preschoolers' conceptions of numbers, focusing on the ontological distinction between numbers and sets of objects. Found that children, like adults, attribute spatial-arrangement properties to collections much more than to numbers, although both are considered to have quantitative…

This paper briefly reviews research on tasks in knowledge-rich domains including developmental studies, work in artificial intelligence, studies of expert/novice problem solving, and information processing analysis of aptitude test tasks that have provided increased understanding of the nature of expertise. Particularly evident is the finding that…

Using similar research in Britain as a basis, a study in New Zealand explored schema learning in young children. The primary purpose of the study was to determine the effects of a curriculum intervention designed to increase the richness and amount of stimulation teachers and parents give 4-year-olds in response to observations of children's…

Collected qualitative data through interviews and triad elicitation with 5-year-olds in London to determine children's current knowledge and understanding of their "making" activity and of Lego construction kit components. Data provided triangulation for another study that found that young children could achieve a great deal with…

The set of goals and plans that a writer might select to accomplish a given piece of writing is guided by the writer's conception of knowledge. In terms of cognitive theory, conceptions of knowledge may be viewed as epistemological schemata--structured clusters of knowledge about the nature of knowledge itself. William Perry's scheme of the…

Two experiments examined preschoolers' and adults' relative reliance on visual and verbal information in identification of animals and machines. Findings include both children and adults can use either visual or verbal cues in categorization, and a stricter definition is used in identifying animals. Results suggest that a perceptual to conceptual…

Schemas are cognitive structures or forms of thought, like pieces of ideas or concepts. Patterns in children's behavior, or in their drawings and paintings, indicate common themes or threads (schemas) running through them. The action research study described in this report examined the effects on children's learning of intervening in their…

This research investigates the development of analogy, in particular, the study of the development of systematicity in analogy. Systematicity refers to the mapping of systems of mutually constraining relations, such as causal chains or chains of implication. A preference for systematic mappings is a central aspect of analogical processing in…

Describes the characteristics of progressive schematization with regard to column multiplication and column division. Contrasts this with column arithmetic based on progressive complexity. Presents a summary of research data concerning column arithmetic. (TW)

Investigates whether distinctions in cognitive structures between formal and concrete operational students effect their ability to produce an accurate cognitive structure, retain geometric content, and retain cognitive structures. Concludes that clear structures can be derived for the students. (Author/YP)

Reviews recent research in the area of mathematical understanding and compares and contrasts it with a model formulated for the growth of understanding. Uses the analysis of a transcript from an interview with an eight-year-old boy to illustrate the power of the model to describe and map the growth of his mathematical understanding. (18…

In this article, the author gives a general introduction of a few ideas on cognitive development in children. In the first part, he deals with the topic of development, a process which concerns the totality of the structures of knowledge. He reviews the stages of development of operational structures, distinguishes four main stages of development,…
