This study investigated a problem within the theoretical structure of cognitive development proposed by Jean Piaget, and used the concepts of classification and projective spatial relationships to investigate the nature of attainment and sequencing of three corresponding logical and infralogical groupings according to the models proposed by…

In an effort to cross-validate a Japanese study, a 16 item test of logical connectives was administered to 223 boys and girls at each grade level (third through ninth grades) and two groups of college sophomore girls. The purpose of the test was to assess their understanding of class inclusion and exclusion, class intersection, and class union.…

Fifty educable retarded children who were determined to be nonconservers by means of three conservation pretests (discontinuous quantity, correspondence, and continuous quantity) were randomly assigned to one of five treatment groups (discontinuous quantity training, correspondence training, continuous quantity training, control, and control…

Two studies attempted to clarify the Intellectual Tasks test assessment of number conservation by testing for two possible artifacts due to procedure: (1) Effects of preceding questions on the following test questions, and (2) operations or manipulations of the test materials by the examiner. Forty Mexican-American first and second graders were…

The research experiments on relational learning in young children contained in this report were guided by two major goals: (1) to examine the extent of conceptual transfer in preschool children, and (2) to explore the relation of both "acquisition" and "transfer" to chronological development. The performance of preschool…

This paper presents the theory that altruistic motives develop out of the synthesis of empathic distress and the child's increasingly sophisticated cognitive development, especially his level of self-other differentiation. An examination of empathy and the sense of other is included, followed by a discussion of empathic distress, various forms of…

This study attempted to determine whether children will relinquish their belief in Piagetian concepts upon presentation of disconfirming evidence. Two age groups were tested: third- and fourth-grade and sixth-grade. Conservation of weight and transitivity of weight were the concepts examined; the discrepant feedback consisted of three trials with…

AN INVESTIGATION WAS UNDERTAKEN TO EXPLORE THE INSTRUCTIONAL IMPLICATIONS OF JEAN PIAGET'S POSITION ON EQUILIBRATION. ONE PURPOSE WAS TO TEST THE GENERAL HYPOTHESIS THAT THE MISCONCEPTIONS OF CHILDREN, WHEN DISPLACED BY EVIDENCE CONTRARY TO THE MISCONCEPTIONS, GIVE RISE TO COGNITIVE CONFLICTS. THE RESULTS, IN GENERAL, CONFIRM THIS HYPOTHESIS. A…

The study was undertaken to determine the possibility of a relationship between the selected traits of cognitive ability, conceptual development, emotional maturity, and perceptual-motor development in disadvantaged kindergarten children, since the knowledge of the relationship between traits might make it possible to strengthen a child's…

Kindergarten and third grade children originally assessed in 1973 were retested one year later on a series of conservation and transitive inference tasks (length and weight content areas). An additional sample of matched cohort/grade subjects was assessed in the second year only to permit evaluation of repeat measurement biases for the…

This study investigates the cognitive and linguistic aspects of the concept of time which is assumed to consist of the components of order (0), simultaneity (S), and duration (D) as well as their coordination, i.e., coordination of order and duration (OD), and coordination of simultaneity and duration (SD). It was hypothesized that each component…

A critical analysis of the current knowlege concerning the development of the concept of death in childhood is the purpose of this paper. Theoretical models and methodological limitations of the literature are addressed. Many factors have been implicated as contributing to the development of the concept of death. (Author/BN)

Describes three studies that examined how young children distinguish between the real, physical world and the mental world; between objects and thoughts; and between doing something and imagining it. (HOD)

Explores the issue of the consistency of use of students' conceptions across different tasks which probed understandings of aspects of pressure, heat, and biological evolution. Findings indicate that children have alternative frameworks for all investigated areas. (ML)

Several studies of the validity of the intensive time-series design have revealed a post-intervention increase in the level of achievement data (the "momentum effect"). Reports on the development and use of a technique to study the effect as it is observed in several data sets on the learning of plate tectonics. (Author/JN)
