This is the latest in a series of reported findings for a Guidance Study which followed the same persons from infancy to age 40. The report focuses on: (1) how well the 50 men and 60 women subjects maintained their positions relative to I.Q. during the 22 years since they were last tested at age 18; (2) gains and losses in I.Q. over the 22 year…

The construct of egocentrism within Piaget's theory of intellectual development was evaluated as to its convergent, discriminant, and predictive validity within the concrete-operational stage. A total of eighty Negro children drawn from grades one through four in low and middle socioeconomic level schools, were tested individually on a total of…

This report describes 3 studies that attempted to determine the impact of college on cultural sophistication. The studies focused on items relating to student's interest in and liking for poetry, fiction, serious or classical music, and modern art.

It was hypothesized that the…

This ecological study is one part of a broad research effort to understand the backgrounds and characteristics of culturally disadvantaged children. The study attempted to provide empirical data which could be used to describe differences in home environments and behavior of three young children from deprived and non-deprived homes.

In this book Piaget considers the way children learn about the world. He addresses such questions as the following: How does a child learn to perceive the world around him? How, for example, does he learn that by grasping an object, he can pull it towards him, or that a ball of clay, flattened, is no smaller than it was before? How does he learn…

Through the meaningful interpretation of sensory data and a background in language experiences, an individual can build more effective knowledge structures. With more effective knowledge structures, one can react more discriminatingly to the written and printed word. Sound knowledge structures involve not only the ability to organize and…

This report summarizes the results of the administration of the vocabulary and Block Design subtests of the WISC to a national probability sample of noninstitutionalized youths 12 through 17 years of age. Information is presented on the derivation of percentile equivalents, normalized scale scores, and a short-form estimate of Face Scale Scores.…

Active and passive sentences were presented with probable and improbable semantic content to 100 first graders and 100 kindergartners. "Irreversible" sentences were considered improbable. In a design employing syntax, probability, grade, and sex as factors, probability and syntax were found significant both as main effects and in their…

The Infant Education Research Project was designed to facilitate the intellectual development of disadvantaged children through a program of home tutoring during the second and third years of life. An experimental group of 31 Negro male infants and a control group of 33 Negro male infants were selected from door-to-door surveys of two…

Inadequacies in most life-span developmental studies are emphasized. A typical cross-sectional comparison of a sample of older adults' performances on a battery of measures revealed that non-surviving subjects and those who refused to be retested 5 and 10 years later scored consistently below retestees. These results point to a heterogeneity in…

A method for reading Piaget is presented in this guide, written for practicing teachers who want better understanding of Piaget's writings. An account of a Piagetian experiment is given, followed by a discussion of its theoretical and practical implications. Eight topics are explored: number, measurement, knots, perspectives, coordinates, floating…

Nineteen papers reviewed the major works published during the most recent four years in the field of psychology. Most of the publications reviewed were American, but due to the stated concern with international coverage, the volume began a series of chapters on psychological research in other countries. Topics reviewed were developmental…

The purpose of this study was to inquire into the relation of intellectual and/or psycho-linguistic development and apparent improvement in other behavior factors such as affective and social behavior and development. Thus consideration is given to the second cybernetics (i.e. the concept of positive feedback or deviation-amplifying relationships…

To test the effectiveness of the cloze procedure for developing comprehension skills in reading at the intermediate level, 189 sixth graders were divided into small groups or asked to work independently during this reading program, which lasted five weeks. The materials were presented both as cloze materials and in unmutilated form, followed by…
