This study examined language ability in children of the same mental age who differed in their level of cognitive development. Subjects were 68 first-graders, 33 male, 35 female, from a predominantly middle-class elementary school. (Author/SB)

Results of two experiments with five-year-olds indicated that: (1) conservation can be quickly taught with lasting results; (2) training on a limited range of exemplars will produce generalized correct responses to other, untrained classes of conservation problems; and (3) children's explanations of their judgments change as a result of exposure…

Event-related potentials (ERPs) of five- to seven-year-old girls were measured while the girls performed a visual selective attention task and a Piagetian conservation task. Results suggested more anterior ERP sources for nonconservers than conservers during early stimulus analysis, and more lateralized ERP sources for conservers than…

A central component in the young child's construction of a number system is an understanding of correspondence. Although current research demonstrates that preschool children use correspondence in a variety of tasks, the nature of the relationship between the use of correspondence action patterns and the use of correspondence as a quantifier is…

Second grade children were pretested for the ability to conserve, after which conservers were paired with nonconservers. Pairs were then instructed to resolve their opposing answers on the conservation tasks. (JMB)

Topics briefly discussed include awareness or consciousness, recollection, reconstitution, and conceptualization; the nature of causal exploration and contradiction; and conservation. Examples are provided in relation to children's perception. For related articles, see TM 501 289 and 290. (RC)

Presents two studies which investigated the importance of subtle contexture factors on the young child's performance on cognitive problems--specifically, conservation. (ST)

The influence of perceptual factors and language comprehension on quantity judgments (number conservation) was assessed in children, aged 2-5. (ST)

Research supported by National Science Foundation grant GE-3 to the University of Minnesota.

The effects of different conditions of peer interaction on the conservation judgments of first and second grade children were investigated. Children were subjected to either a control group situation or one of four types of peer interaction (cognitive conflict, social interaction, modeling, or cognitive dissonance) in which they were presented…

The author attempts to analyze and synthesize the literature on the development of conservation (Piaget) in children in order to aid its use as a routine assessment instrument of an important aspect of cognitive development. The nature of conservation, a review of the literature, task variables, and training variables are discussed. The author…

Tested was the hypothesis that science instruction based on task analysis will lead to the acquisition of the ability to perform certain Piaget volume tasks which have been characterized as requiring formal operations for their solutions. A Test on Formal Operations and a Learning Hierarchies Test were given to fourth- and sixth-grade students in…

This document describes experimental attempts to teach young children the concepts of conservation of number. Subjects were 48 nursery school children who were divided into experimental and control groups. All children were individually pretested for conservation, after which the experimental group alone received two training sessions. The…

Twenty-six children ranging in age from 6 to 12 years whose tested IQ's were over 160 were tested on three Piagetian tasks of advanced concrete operations and two tests of formal operations. All children passed all concrete operations problems, but only four of the oldest boys passed the formal operations tasks. Findings are discussed in terms of…

The general objective of this study was to study Piaget's notion of the sequential development of number conservation in 85 children averaging 5.9 years of age. The question addressed was to determine if a set of ten equal addition conservation of number tasks were scalable. A large coefficient of reproducibility, .912, was computed. Other indices…
