Discusses Needham's findings by asserting that they extend understanding of infant perception by showing that the memory representations infants draw upon have bound together information about shape, color, and pattern. Considers the distinction between two senses of "recognition" and asks in which sense object recognition contributes to object…

Examined analog number representations in 5- to 7- year-olds. Found that subjects accurately estimated rapidly presented groups of 5 to 11 items. Children's data were qualitatively and to some degree quantitatively similar to adult data, with one exception. The ratio of the standard deviation of estimates to mean estimates decreased with age.…

Three experiments examined assumption that children attribute human properties to nonhuman agents. Two- to 8-year-olds participated in false-belief tests concerning human and various nonhuman agents, including animals and God, and in a modified perspective-taking task including nonhuman agents. Results suggested that children do not consistently…

Presents a developmental model integrating attachment theory and cognitive developmental approaches in order to further understanding of the processes involved in loss and grief. Considers the relevance of attachment theory to understanding grief and research evidence for the role of continuing attachment bonds after death as a strategy for…

Three studies explored 2- to 4-year-olds' ability to categorize objects based on novel underlying causal power. Children saw that a "blicket" would set off a machine and participated in categorization, induction, and association tasks. Results demonstrated that even 2-year-olds easily learn about an object's new causal power and…

Investigated strategies used by preschoolers to accomplish a repeatedly requested practical task. Participants satisfied customer requests for vegetables in a play store, with the number of moves and strategy type recorded and coded. Arithmetic pre- and posttests were also administered. Found that with repeated exposure, the children became…

Describes an ethnographic study of African American toddlers and families that focused on children's productive competence in naturally occurring narrativelike conversation. Examines emergence of narrative competence; posits definition incorporating minimal requirements for child participation within the fundamental essence of narrative structure.…

Reviews Thelen and Smith's book and its account of "how knowing develops from doing." Concentrates on the nature of dynamic systems. (DR)

Examines preschoolers' understanding of non-observable causal mechanism in causes of illness. Three studies were conducted using subjects from university child care centers. Subjects average five years of age. Results indicated that preschoolers recognize that appearances may be deceiving when it comes to judging causes of illness. Discusses…

Two studies examined the acquisition of automatic processing in a total of 22 persons with and 34 persons without mental retardation. An effect of search set size was found for both groups which disappeared with practice. Evidence of automaticity occurred with less practice for subjects without mental retardation. (Author/DB)

Investigated how different contexts for learning affect the development of memory-enhancing strategies in children. Subjects were children four to seven years old. Results indicated that the number of items recalled in the lesson condition was significantly greater than in the game condition, and the grade effect was also significant. (MOK)

Examined the relationship between 6- to 8-year olds' conceptual understanding of additive composition, commutativity, and associativity principles and addition problem-solving procedures. Results revealed that conceptual understanding was related to using order-indifferent, decomposition, and retrieval strategies and speed and accuracy in solving…

Examines the distinctions and interrelations between necessary and contingent knowledge and relates these concepts to the distinction between scientific and empirical validity. Considers how these distinctions can be applied to an understanding of morality, arguing for a relational rather than absolutist approach to questions of necessity. (JPB)

Maintains that there are core-specific and non-core-specific domains of knowledge, but that only the core-specific domains benefit from innate skeletal structures. Asserts that core skeletal domains are universally shared, even though their particular foci may vary. Emphasizes that individuals vary in terms of the noncore domains they acquire.…

Compares and contrasts working memory theory of Baddeley and theory of constructive operators of Pascual- Leone. Concludes that although the theory of constructive operators is complementary with working memory theory (explains developmental and individual differences that working memory theory cannot), the converse is not true; theory of…
