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…

Five-year-old children who failed pretests of conservation of Number, Length, Mass, and Liquid Amount, but who possessed counting ability and knowledge of the terms "same" and "different" underwent Training and Conservation Posttests. (Author/CS)

An investigation was made of the extent to which mental operations involved in quantitative conservation and pretense play affect the development of gender constancy. The research design included three phases: a pretest establishing subjects' levels of conservation and gender understanding, a training phase, and conservation and gender constancy…

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

To discover what aspects of number conservation tasks prevent young children from conserving, two components of number conservation tasks were investigated. A test was made of the following two hypotheses: (1) the frequency of conservation responses varies significantly with the materials used, (2) the frequency of conservation responses varies…

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…

In testing conservation of number in preschool children using both equality and inequality; 3- and 4-year-olds tended to use an acquiescence response set while 5- and 6-year-olds responded in terms of relative length. (ST)

Piaget and Inhelder's Water-level Task, the Preschool Embedded Figures Test, and a mental processing measure called Mr. Cucui were administered to 42 four-year-olds. The significant correlation between Mr. Cucui and the horizontal/vertical bottles was discussed from the neo-Piagetian perspective of Pascual-Leone's theory of constructive operators.…

In a replication study, children 3 and 4 years old were given verbal rule training in order to probe the importance of identity, reversibility, and compensation explanations in training number and length concepts. Among the results, as before, identity was found to be the most significant factor in conservation acquisition. (Author/RH)

Two experiments were conducted to investigate children's performance on different number versions of identity and equivalence conservation tasks. Subjects were 88 children ranging in age from four to six years. (MP)

Studies the effects of modeling and reversibility cues in teaching 4-year-olds to conserve length. Results are discussed in terms of a social learning viewpoint of cognitive development. (ED)

The present study was designed to assess the effectiveness of certain cognitive training tasks on children in group settings under natural preschool conditions. Thirty-five children, aged 47-63 months, were divided into six experimental groups and received various cognitive tasks. Results indicated that most children experienced at least moderate…

The Piagetian operations of multiple classification, multiple attributes, seriation and reversibility were used to develop an "equilibrated methodology" to help preschool children conserve quantity. Randomly assigned experimental and control groups within morning and afternoon classes at a nursery school were used to evaluate the…
