Conservation and executive function (EF) are important early childhood skills; however, knowledge about their relationship is scarce. Hence, in this study, this relationship is investigated, and a comparison is conducted between the Piagetian conservation and EF tasks to obtain the total hemoglobin (mMmm) for the left and right brain activity in…

This article describes some aspects of Piaget's Theory of Cognitive Development. It highlights the importance of giving young children specific access to explore conservation in measurement, which will give students invaluable experiences in measurement that in years to come will be regarded as their prior knowledge of the concept. This is…

A total of 4six children with a mean age of 6 years were randomly assigned to either a standard or modified testing condition in order to assess their conservation judgments. Significantly higher levels of "conserving" judgments were obtained in the modified condition. (Author/CI)

This study was supported by a grant from the Carnegie Corporation to Educational Testing Service. (MH)

Micronesian children residing on Truk and Kosrae were examined for performance on eight conservation tasks and on one task each of centration and reversibility (generally precursors of conservation in Piaget's theory of cognitive development). A total of 75 children were tested--33 in the village of Moen, Truk, and 42 in all the villages of…

This study replicated a study by Mehler and Bever (1967) which had reported conservation observed in very young children between 2 years 4 months and 2 years 7 months old. Both Piaget (1968) and Bielen (1968) criticized the Mehler-Bever finding, claiming that true conservation had not been demonstrated. The investigator in the present study sought…

Use and understanding of dimensional language facilitated conservation. (ST)

"For seven to nine year old children, it is easier to conserve weight on plasticine rather than on a rubber band or on alcohol in a thermometer . . . Boys perform significantly better than girls." (Author/AL)

Reports results of short-term training procedures upon the acquisition of the concept of conservation in children. (DR)

Twenty-one male and 21 female adolescents were tested individually for conservation of mass, weight, and volume. (CM)

An empirical test of alternative claims by Bryant and Piaget concerning the development of invariance of quantities in 3- and 4-year-old children was made. Results support the Piagetian thesis in showing that those subjects respond with stereotypic strategies rather than by an invariance of number principle. (Author/JMB)

This study was designed to assess the acquisition of conservation of number on equal addition tasks through scalogram analysis to determine if this analysis defines a scale or continuum. Ten block tasks administered to 85 kindergarten children validated Piaget's theory that cognitive development is sequential and continuous. (Author/ED)

To analyze the relationship of logical development and comprehension of syntax, 60 children aged 5-8 years were individually tested. Measures included class inclusion, conservation of substance and weight, a sorting test, and a test of comprehension of active and passive sentences. Class inclusion was not strongly related to syntactical…
