Studied 2-year olds' understanding of pretense expressions of independent agency in scenarios in which a doll acted as the agent of a series of pretend events. Found no gender differences in the doll's imaginary intentions, but older toddlers performed reliably better than younger. Episodes requiring enacting conclusions to events that began with…

Four experiments assessed infants' ability to solve isomorphic problems and explored the nature of early representations. Found that 13-month-olds transferred a modeled strategy across isomorphic problems, whereas 10-month-olds transferred only after multiple source problems or high perceptual similarity between problems. Comprehension of the…

Examines the effects of mothers' strategies of combining employment and welfare receipt during the first three years of their child's life on the child's cognitive development, behavior problems, and home learning environment at ages five and six. No negative association was found on most child outcomes with a mother's employment whether or not it…

Examined in 4 experiments 2-year-olds' knowledge of solidity in search tasks. Found no evidence that 2-year-olds represented solidity and support constraints on trajectories of falling objects; two experiments included 2.5-year-olds who succeeded on search tasks. Explored implications of 2-year-olds' poor performance in light of very young…

Reflects on Needham's findings on infants' object recognition and segregation. Examines the role for perceptual bias in explaining infant performance, places Needham's studies in historical perspective, and assesses their theoretical significance. Discusses the merits of positing different kinds of information sources for object segregation, and…

Examined how 6- to 9-year-olds and adults judged expected value of complex gambles in which alternative outcomes had different prizes. Found that participants at all ages used multiplication rule for integrating probability and value of each individual outcome, and based judgment of overall expected value on alternative outcomes. Even youngest…

Three studies examined lexical categorization in 2-year- olds. Findings indicated that even with minimal opportunities to familiarize themselves with novel artifacts, children generalized their names in accordance with the objects' functions, even when they had to discover the functions on their own or when all the test objects had some…

Three experiments assessed children's abilities to track behavioral, representational, and truth aspects of conventions. Three- and 4-year-olds recognized that conventional stipulations would change behavior, but not how stipulations might affect representations. Three- and 5-year-olds confused pretenses and conventions; 7-year-olds consistently…

Notes contemporary models of human development have expanded to address a wider set of issues underlying personal change. Discusses the social cognitive model of self-regulatory development. Emphasizes the crucial development of self-regulatory competence: the point at which the processes of development become fully and reciprocally interactive…

Five experiments using the visual habitation paradigm with 158 infants demonstrated that these 10-month olds did not use property/kind information to establish representations of 2 numerically distinct objects, a finding that provided support for the object-first hypothesis. (SLD)

Compares differences in Noam's (PS 524 984) and Cicchetti's (PS 524 985) viewpoints to their shared idea that our understanding of human development has much to gain from the emerging field of psychopathology. Describes Noam's approach as intended to blur the boundaries between optimal and pathological development, and Cicchetti's approach as more…

Discusses the two major theoretical traditions from which the ideas discussed in the Noam (PS 524 984) and the Cicchetti (PS 524 985) articles in this issue are drawn. Describes their divergences from traditional Piagetian and attachment theorists, and the approaches each has taken to common themes in their work. Concludes by setting out…

Reviews concepts of meaning making in classical and contemporary writing. Examines models of cognitive and ego development linked with meaning making and draws a model of the relationship of meaning making to adult learning and development. (SK)

Argues that the limited resources with which organisms start their development make possible certain kinds of learning which otherwise would be highly problematical. Discusses limitations of the cognitive structure of the organism, learning, and its problems in connectionism. Maintains that the knowledge gained from efforts to overcome problems…

Comments on Raftopoulos article (PS 528 649) on facilitative effect of cognitive limitation in development and connectionist models. Argues that the use of neural networks within an "Artificial Life" perspective can more effectively contribute to the study of the role of cognitive limitations in development and their genetic basis than…
