The objective of this study was to assess the ability of a previously prepared diagnostic test to detect the need for remediation in preschool children and then to assess the effectiveness of specially designed remedial materials. The subjects consisted of 47 boys and 25 girls from four private kindergartens in Nashville, Tennessee. All subjects…

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…

The purpose was to investigate the influence of variations in conservation form and perceptual modality on the expressed level of understanding of the conservation of weight concept, and to determine if these variations result in significantly different observed rates of concept development. Sampling included 225 children, five to twelve years…

Suggests that although Piaget's psychological theory is developmental and dialectical in a general way, the lack of a developed philosophical basis leads to the subordination of a dialectical approach to static, anti-dialectical concepts. Hegel's theory of interaction and contradiction is examined to show that dialectical theory has a precise…

Presents a study of the development of conservation of weight among socially deviant adolescents. (BD)

Examined the relationship of ability to conserve and comprehend of logical riddles in 33 first-, third- and fifth-grade boys of average intelligence. Although both riddle comprehension and cognitive maturity as assessed by Piagetian tasks increased with grade, the relation between them was not clearly demonstrated. (Author/JMB)

The relationships between perception and conservation of length were investigated in a developmental comparison of judgments of length made by 5-year-olds, 8-year-olds and adults. (GO)

A comparison of 28 mildly mentally retarded children with 28 children of average intelligence (mean mental age six years) in learning conservation skills found both groups benefited from Direct Instruction methods, but retarded children acquired only pseudoconservation from Observational Learning methods. Their learning was not tenacious and did…

A longitudinal investigation on development of conservation skills in 31 learning disabled (LD) children suggested that delayed transition between preoperational and concrete operational thought may be an important factor in understanding the continued school failure of learning disabled children. (Author/CL)

Perceptual counterparts of a series of conservation of length tests were presented to subjects who were categorized as conservers or nonconservers conservation of length pre-tests, and to conservers and nonconservers given conservation length training. Perceptual performance of the untrained nonconservers was significantly worse than that of the…

An abstract of a study done during doctoral work (Temple University, Philadelphia, Pennsylvania). (RJ)

Data gathered on 92 girls (6-10 years of age) tested on Piagetian conservation tasks supports a theory of perceptual activity leading to decentration and indicates a change in viewing strategy associated with change in conservation status. (WY)
