The purpose of this study was to test the effects of an experimental method of instruction upon the cognitive development of disadvantaged first grade children. The hypotheses formulated were: (1) there is no difference between the medians of the control and experimental groups or between the numbers of subjects in each group placing at the…

This document reports an investigation of the relationship between maternal practices as observed in the home and the cognitive development of young children from low-income families. The purpose of the study was to determine if lower-class maternal warmth was associated with intellectual growth of the child. Fifty-two lower class mothers were…

This study compared the effects of two specific post-laboratory discussion strategies in science on the development of the four cognitive skills of observation, inference, verification and classification. The two strategies were: (1) teacher-dominated, in the form of organized lectures based on the data students had collected; and (2)…

The purposes of this study include: (1) determining whether socioeconomic status (SES) or verbal ability (VA) exerts greater influence on childrens' performance of Piagetian tasks; (2) devising an instrument for measuring childrens' level of cognitive development which does not depend on verbal ability alone; and (3) adapting materials for teacher…

This pamphlet summarizes the interim report of the Head Start Planned Variation Study although information from other sources is included. During the pilot phase (1969-1970) eight distinct approaches to preschool education were analyzed with regard to the nature and extent of implementation of early education models and program effects. The first…

Three language models (Staats, Lenneberg, and Piaget) are reviewed, and implications for reading are suggested. Staats' behaviorist stance maintains that imitation, mediation, generalization, and discrimination are key concepts in language learning behavior. Critics contest the importance of these concepts and claim that behaviorists cannot fully…

Language as an identifiable cognitive behavior must be studied in relation to identity and memory, all of whose structures undergo progressive changes as the child develops. The organization of the development of the organism depends upon relatively ordered structures of growth, following foreseeable pathways or creodes. The processes occurring…

The study assessed contributions of different novelty pairings and reward types to exploration behavior across three successive discrimination learning problems in a 3 x 2 x 3 mixed design. After learning a simple two choice discrimination problem, Headstart subjects responded to six double reward trials and six extinction trials. A…

The sequence of development as hypothesized by Piaget has been confirmed for various groups of children by cross-sectional and longitudinal studies. Such consistency has increased interest in constructing scales based on Piaget's theory according to psychometric principles. Three major problems are discussed which present definite obstacles in the…

Chapters contained in this volume, each with a list of references appended, are: "Scientific Psychology in Transition" by Gregory A. Kimble; "Higher Mental Processes as the Bases for the Laws of Conditioning" by Eli Saltz; "Reification and Reality in Conditioning Paradigms: Implications of Results When Modes of Reinforcement are Changed" by David…

The pleasures and benefits of talking to one's self are presented in the context of self-understanding. The types of "self-talk" noted are writing, the trying out of future conversations to one's self, and soliloquizing before groups of people. Futhermore, speculation about the relation of the right and left hemispheres of the brain and…

A study was conducted to clarify a number of issues related to Piaget's theory of invariant sequantiality in child cognitive development. Ss were 143 middle-class white children of bright, average and retarded psychometric abilities (measured by performance on the Stanford-Binet Intelligence Test). Bright and average Ss were chronologically aged…

A booklet is presented for parents of blind children. This booklet lists various toys that are useful for the child in his development and cognitive growth. Three kits of toys are presented. Each of these kits was developed for children of approximate age groups. Kit #1 is for the very young blind infants and contains toys that usually interest…

This document is an English-language abstract (approximately 1,500 words) of a book in which the author sums up her research on the problem of training and transfering various types of mental activity. The second part of the book deals with one of the most important problems of mental development, that of the evidences and conditions of…

The author presents a discussion of certain portions of Arthur Jensen's controversial article. The general conclusion is that Jensen has not provided substantial evidence that there are differences in neural structure among children from different social or ethnic groups which are genetically determined. The reviewer reacts to Jensen's conclusion…
