Examined was the association between affective and cognitive development in 14 Down's Syndrome infants (4- to 8-months-old). Mothers administered a series of 30 laughter items each month, and experimenters gave the Uzgiris-Hunt scales of cognitive development at 13 and 16 months, and the Bayley scales and Infant Behavior Record at 16 months.…

The inventory is an individually administered procedure designed to assess the cognitive skills of preschool children enrolled in the Living Room School (LRS) program. It was developed to measure change in the cognitive behavior of the 2- to 5-year-old child as well as to diagnose his performance patterns in order to formulate an individualized…

The generalization of acquired competencies, specifically flexibility of closure, was the subject of this research. Flexibility of closure was defined as the ability to demonstrate selective attention to a specified set of elements when presented within various settings (the larger the number of settings from which the desired set of elements can…

This paper describes a program of research in the application of scalogram analysis to the validation of learning hierarchies, together with the development of an alternative method for assessing hierarchical relationships among tests of instructional objectives. The relationship between scalability of tests and positive transfer between…

Studies of the infant's distribution of attention to stimuli of varying complexity, and of his differential attention to familiar versus novel stimuli (discrepancy), have attempted to shed light on the development of cognitive structures in the non-verbal infant. The subjects have typically been normal infants ages 4 to 6 months. For testing, the…

This study reports a factor analysis of the data resulting from a 3-year longitudinal investigation into conservation of number and related mathematical type concepts. Conservation of number, which represents a subset within the concept of conservation, was measured by use of a 20-item, criterion-referenced testing device. The subjects, who were…

The language, intellectual, and social deficits of economically deprived children are the targets of a 4-year study designed to follow the educational progress of a group of deprived children from preschool through grade 3. This document reports on the preschool year, the first phase of the longitudinal study, which investigated whether or not…

The study was divided into three major phases: to develop a mathematics curriculum for educable mentally handicapped; to develop a measurement instrument to evaluate the children's learning at various cognitive levels; and to determine the relative effects of two instructional approaches (inductive and deductive), two forms of repetition (exact…

Studied were attitude changes as results of instructional procedures for success in problem solving by 350 eighth grade students in two school systems during the 1968-69 school year. Mimeographed instructional materials and techniques incorporating five levels of problem solving difficulty were developed. Procedures for student success…

To continue exploration of the educational problems of deprived children, 32 disadvantaged and 32 advantaged children ranging in age from 4 years, 8 months to 5 years, 8 months, were selected to take a battery of tests designed to measure some of the skills and characteristics thought to be related to academic success. The factors measured and the…

This study investigated (1) the nutritional status of urban American disadvantaged children, (2) the relationship of nutritional status to mental growth and development, (3) the relationship of physical maturation to the development of perceptual-motor factors of intelligence, and (4) if found, the effects of undernutrition on intellectual…

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…

This study was planned to examine differences in the ability to stop and think, and knowledge of comparative concepts, among children who succeeded or failed in solving verbally presented class inclusion problems. Thirty third-grade boys were classified as non-Inclusion subjects, and 30 others as Inclusion subjects. The children were classified as…

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…

This paper discusses beginning reading instruction in the light of Piaget's theory, which demands that we think more broadly about the term "where the child is" in terms of his level of thinking, not simply his reading level or reading skill level. Using Piaget's four major developmental stages as the basis, the task of instruction in…
