Observationally induced concept acquisition and generalization were studies in 132 second graders, using a clustering task. Groups were provided with a live or target model and different types of verbal coding. (ST)

Addresses Nelson's commentary on Ward, Vela, and Hass' study of children's category learning (both of which are in this issue). Discusses the issue of whether a holistic processing view provides a better account of children's learning than does an analytical view. (PCB)

Three experiments examined the modes of processing that children and adults use in learning family-resemblance categories. Children and adults exhibited primarily analytic, rather than holistic, modes of learning. (PCB)

Comments on this issue's article by Ward, Vela, and Hass on children's category learning. Suggests that aspects of the authors' methodology may have led them to underestimate holistic processing. (PCB)

Reports the results of one study in which parents taught their two- to four-year-olds basic and superordinate concepts, and another, in which they taught them subordinate concepts. Parents' teaching styles were analyzed in terms of their usefulness for children who are attempting to learn about principles of hierarchical classification. (AS)

Two concept-formation experiments were conducted with groups of American and Liberian Ss differing in age and educational background. (Authors)

Preschool children were trained to acquire transitivity, conservation, and class inclusion of length via feedback to their judgments. Feedback was found to facilitate the learning of all three concepts. (ST)

Results lend support to the notion that children at different ages are differentially responsive to various conceptual-strategy models. (Author)

Examined role of social-referential context in 13- and 18- month-olds' mapping of verbal and nonverbal symbols to object categories. Found that infants at both ages showed evidence of learning both words and sounds when the experimenter produced a label within a familiar naming routine, and failed to learn when labels were emitted from a baby…

Four experiments investigated children's ability to notice and remember events in which the acquisition of factual information occurs. Results indicated that children tend to report they have known newly learned information for a long time, suggesting that children have some understanding of knowledge acquisition, but not at the level of adults.…

Examined the nature of perceptual classification in children and young adults. Found that most children attend selectively to one stimulus dimension when making perceptual classification judgments. Suggests that this developmental trend does not appear to be a holistic-to-analytic shift but rather a trend toward greater consistency in following a…

Two experiments investigated perceptual primacy of dimensional and similarity relations in stimulus classification of mentally retarded children. Results support a distinction between separable and integral stimulus structures, but do not support an integral-to-separable shift in perceptual development. Results suggest implications for…

Presents the results of three studies examining children's conception of the mind itself as an independent, active entity. Findings revealed a developing ability in children to interpret and produce statements personifying the mind and provided considerable evidence of children's movement toward a conception of the mind as an active agent…
