This study attempted to identify the factors of intelligence associated with the solution of a Piagetian task. Liquid conservation and 18 psychometric tests which included subtests from the WISC, ITPA, Raven Matrices, Primary Mental Abilities, and others were administered to 133 first- and second-grade boys and girls. (MS)

Preservice teachers administered Piagetian tasks to elementary students. On the whole data collected compared favorably with the findings of Renner (EJ 044 727) in showing that students achieved conservation of substance (liquids and solids), length, area, and weight at later ages than stated by Piaget. No significant sex differences were found.…

The purpose of this investigation was to determine the relationship between the acquisition of conservation skills and achievement in mathematics. The conservation skills measured were numbered, mass, area and volume. Mathematics achievement was measured by the Computation, Concepts, Problem-Solving and Total Mathematics scores on the Metropolitan…

This investigation was an attempt to determine the best predictors of behavior, explanation, and composite scores for conservation of two-dimensional space, substance, continuous quantity and weight in non-retarded and retarded children. The subjects were 60 non-retarded children randomly selected from grades K-2 in one school, and 58 children…

The study attempted to trace the relationship between facility with cardinal-ordinal aspects of number; attention to dimensions of number, length, and density; and the presence and absence of number conservation. On the basis of performances on the standard test for number conservation, 25 nonconserving kindergarteners, 34 conserving…

Piagetian conservation tasks in relation to standard intelligence tests with mildly mentally retarded students from different ethnic groups were investigated. Seventy-five boys between the ages of 10 and 15, who scored between 65 and 80 on the WISC, were studied. Elkind's procedures for conservation of substance, weight, and volume were used.…

Reported is a study of the development of conservation and measurement concepts, with reference to certain task factors which may affect performance. A group of 129 first and second graders were given a test of conservation and measurement consisting of five problem types crossed with three transformation types. The problems all involved moving…

A group of 47 kindergarten and first grade children from a school chiefly composed of Negro children from low-income families was involved in this study which followed a Solomon four group design. All children received a pretreatment of 17 lessons on matching relations and length relations. The pretest group was then given six tests on relations,…

Examined the development of stable concepts of "boy" and "girl" in kindergarteners and first and second graders. Gender constance was explored in relation to: performance on conservation tasks; application of gender label to self or other; application of gender label to live person or pictorial representations; and sex role…

This study examined the effects of 3 situational contexts varying in demands for accuracy and speed on the performance of 45 kindergarteners and 45 second grade students on the Matching Familiar Figures test of cognitive style. (JMB)

First graders' length conservation was measured using a verbal and nonverbal test, and the results were compared as predictors of mathematics achievement. Findings showed that verbal conservation scores were superior to nonverbal conservation scores and to intelligence scores for predicting achievement. (DT)

The primary purpose of this study was to investigate conservation acquisition across subcultural groups. (Author)

A combination of readiness and body-part training was the most effective in producing number conservation with external objects. (Authors)

Results provide little support for viewing decentering ability as the major cognitive skill underlying developmental trends on tasks of cognitive perspective taking, peer description, humor understanding, and causal attribution. (Author/BH)
