Non conserving first- and second-grade children were tested on conservation tasks. Eye movements were recorded during the response period for each task. Trained conservers showed more visual exploratory behavior and less perceptual centration than control subjects. (ST)

Investigated whether children will relinquish belief in Piagetian concepts upon presentation of disconfirming evidence. The conservation of weight concept extinguished more readily than transitivity of weight, and only for the latter was a developmental trend evident. (DP)

Preschool children were trained on a color relevant oddity problem by one of 3 methods: (1) increased salience of the oddity relationship, (2) instruction on solution rule, or (3) a combination of both. Generality of results were probed with a form-relevant transfer problem. (DP)

Discusses the concept of bioplasmic forces--the foundation of human growth, regeneration of cells, and life energy--and the relationship between physical and mental development of the child, focusing on the theory that premature or forced learning may cause intellectual or academic retardation. (TO)

Three tables outline a framework for conservation and environmental studies curriculum development. (KM)

Preschool and kindergarten nonconservers (N=114) were examined for their use of dimensions relevant to quantity in two conservation-of-substance tasks. The results were interpreted as being counter to Piaget's 4-step equilibration model of the development of compensation and conservation. (ST)

Using a developmental model, this article uses a hierarchy to describe the developmental reinforcement process as it occurs in a child's life and discuss some educational consequences of a deficit in this development. (Author)

Paper present the findings from a study focusing on the relationship between levels of object concept construction and achievements in several other branches of functioning. (Author/CB)

According to transfer index testing, chimpanzees who had been reared in restricted laboratory environments for the first two years of life were inferior in cognitive skills to wild born control subjects. Findings are discussed in terms of the role of early experience in cognitive development. (DP)

Investigated developmental changes in children's judgments of age of people in photographs with emphasis on judgments correlating age and physical size. Results were discussed in terms of previous age perception studies and Piagetian Theory. (DP)

Explored children's conceptions of death from a Piagetian framework. Significant changes in the direction of more realistic attitudes by children were noted as levels of cognitive development advanced. (DP)

Piaget's constructs of concrete-operational and formal-operational stages are illustrated by quoting comments from Piaget and Inhelder (1958), summarizing the kinds of reasoning to be expected at each substage, and relating this reasoning to specific mathematical items. (DT)

This paper relates the function of history as a discipline of knowledge to the student's cognitive abilities and development. (Author)

Results were interpreted supporting a social learning view of observational learning that emphasizes contral processing of response information in the acquisition phase and motor reproduction and incentive processes in the overt enactment of what has been learned. (Author)
