Sixty middle class children (mean age 78.6 months) were tested to determine if recognition of identity precedes recognition of quantitative equivalence when dealing with quantities of liquids. When measuring conservation, the importance of two aspects of language (semantics and syntax) is stressed. (Author/AJ)

Attempts to clarify the meaning of differentiation in the Piagetian concept of object permanence. (BD)

Tests designed to measure conservation, visual memory, and static and anticipatory imagery were administered to 1st and 2nd grade children. Conservation and memory correlated significantly with IQ. The different mental processes may be involved in the development of anticipatory imagery and conservation. (CS)

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…

Hypothesizes that children may misunderstand the task required by Piaget's test and that researchers may therefore underestimate the children's cognitive capacities. Tests the hypothesis by dividing 48 children of both sexes into two groups, those taking the standard tests and those taking a test restructured to limit ambiguity. (BE)

A pretheoretical model of cognitive development is proposed which is based on the empirical establishment of Gagne's cumulative learning sequences. (Author)

Suggests some difficulties and challenges in understanding and teaching Piaget's new theory. Outlines some differences between Piaget's new and standard theories, such as the diminished status of the emergent skills that mark the onset of concrete operational thinking and the perception of achievements in concrete operations as empirical…

The influence of language and familiarity with clay upon performance of traditional tasks involving conservation of quantity and weight was examined. Children from a village in which all the women are potters did not perform differently from their peers in a neighboring village on any task. (MS)

Examines the possible effects of cultural and epistemological factors, such as mythicomagical and empiricoscientific thought, on conservation task performance. (BD)

Suggests that although Piaget's psychological theory is developmental and dialectical in a general way, the lack of a developed philosophical basis leads to the subordination of a dialectical approach to static, anti-dialectical concepts. Hegel's theory of interaction and contradiction is examined to show that dialectical theory has a precise…

Although the ability to conserve number held up well with age, quantity conservation performance was generally lower in the subjects over 65 years of age than in the college and adult age groups. (Author)

Suggests that Greenberg's challenge to the centrality of object permanence in developmental thinking reveals that developmentalists' theories about childhood speak about their own self-images. Notes that developmentalists have been guilty of not only the object permanence fallacy but also the genetic fallacy, or the mistaken belief that describing…

Results of administering Piagetian tests of concrete and formal operations to 6- to 11-year-olds whose IQ's were in excess of 160 support the reality of Piaget's stage structures but suggest that the speed with which tasks within a stage are mastered is a function of intelligence in the psychometric sense. (Author/SDH)

Provides clarification of the Piagetian theory of the development of conservation and reviews the state of knowledge regarding the theory. It is concluded that reasonable evidence exists suggesting that conservation by identity precedes and induces the emergence of conservation by inversion and compensation. (Author/DB)

This paper examines structural paradigms for the analysis of narratives drawn from Levi-Strauss, Propp and Piaget. It shows that all are successful in differentiating between the stories freely told by children of different age levels ranging from 2 to 12 years. (MS)
