Looks at the general effects of bilingualism on cognitive development and highlights the specific effects of bilingualism on third language acquisition. Examines effects of bilingualism on cognitive development, metalinguistic awareness, and communicative skills, then focuses on the specific effects of bilingualism on third language proficiency by…

Developmentalists have overlooked the problem of the real impermanence of things. Though the metaphor of impermanence is central to Piagetian and neo-nativist accounts of representation, the development of the understanding of impermanence is unstudied. This article proposes that the development of the concept of impermanence is distinct from the…

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…

Critiques the metaphor of child-as-theoretician. Argues that comparisons between the cognitive development of an individual and the historical development of a scientific theory are deeply misleading. Further argues that, although there are similarities between children's cognitive enculturation and adults' continuing education, individual…

Used a framework-isolating analysis of knowledge and control of processing components to investigate preschoolers' acquisition of cardinality. Found that cardinality emerges gradually in children between ages three and five. Also, tasks that increase the processing burden of a basic counting problem by adding demands for either analysis or control…

Investigated the pedagogical quality of physical space by adapting a classroom to create a material "educational field" and testing children's performance on a "go to the front and right of the tower" activity. Found that the educational field made it possible for children to put into relation two spatial reference systems and…

Three studies investigated how experiencing nearby locations together in time influenced memory for location in 7-, 9-, and 11- year-olds and adults. Findings suggested that experiencing nearby locations together in time increased the weight children assigned to categorical information in their later estimates of location. Results were similar…

Explores the question, What is the role of school grounds as sites for learning? Observation and interview data from five Australian primary schools displayed large differences between schools in the types of play that 8- to 10-year-old children engaged in, particularly play behaviors categorized as involving environmental cognition. Explores the…

Integrates recent views of early perceptual-cognitive growth with accounts on the development of communication in infancy. Emphasizes supporting evidence for a view that combines innate perceptual and constructive mechanisms with associative memory in explaining how human infants process information. Also considers how the sociocultural…

Two experiments with monolingual German-speaking 2.5- to 4.5-year-olds showed a consistent developmental gap between children's memory/inference of what someone wanted and what someone wrongly said or thought. Correct answers emerged with mastery of the false-belief task. It was concluded that the observed gap constrains de Villiers's linguistic…

Considers how theories of learning can inform the practice of science teaching in formal settings and describes two broad strands of learning theory that have been drawn upon in science education, namely individual and sociocultural views. Shows how aspects of both views can usefully inform understanding of teaching and learning in science in…

Explores new doctors' perceptions of their educational development during the first year of postgraduate training. Uses semi-structured open interviews with pre-registration house officers and investigates their views on the importance of their experience to the General Medical Council's competencies. (Author/KHR)

Attempts to integrate the formulations of Brehm and Brehm and of Guidano and sets forth a cognitive theory of resistance and reactance within a cognitive developmental and individual differences context. Differentiates resistance from reactance and explores developmental antecedents of characterological reactance. Describes implications for…

Explores the use of the term "voice" in written discourse as a metaphor for "authority," a quality that distinguishes an effective writer. Proposes a "scale of negotiation" and a sequence of assignments for a 15-week term in which students gradually establish a position of authority over their texts. (RS)

Investigated the hypothesis that the meaning young children attribute to the word "big" may depend differentially on the object of reference. Children three and five years of age who were shown pairs of buildings and pairs of cars used a height rule for both classes of objects when interpreting big. (NH)
