Examined influences on African-American children's cognitive development between 6 months and 8 years. Found that more optimal patterns of development were associated with intensive early educational child care, responsive home stimulation, and higher maternal IQ. Child care experiences were related to cognitive performance through enhancing…

Comprehension of reversible active and passive sentences was studied with 48 Japanese children between the ages of two and six. Four types of sentences were constructed using passive and active structures and two word orders: subject-object-verb (SOV) and object-subject-verb (OSV). The basic order of elements in a simple sentence in Japanese is…

TWO STUDIES DEAL WITH THE THOUGHT PROCESSES CHILDREN DISPLAY WHEN FACED WITH PROBLEMS INVOLVING THE CONCEPTS OF QUANTITY AND NUMBER. INVOLVING CHILDREN IN KINDERGARTEN, FIRST GRADE AND SECOND GRADE, THE STUDIES USE PIAGET'S THEORIES IN BOTH A CROSS-SECTIONAL AND A LONGITUDINAL APPROACH TO STUDY CHILDREN'S THINKING IN AN EDUCATIONAL SETTING. TO…

Two studies examined modifiability in intellectual functioning in older adults. The fluid-crystallized theory provided a theory base for the research. (Fluid intelligence follows a normative decline through adulthood, while crystallized intelligence remains stable or even increases.) In the first study thirty subjects (average age 69.2)…

The recent experimental literature on the acquisition of English antonyms is reviewed, with special reference to the position of Eve Clark and the particular ontogenetic assumptions her position entails. The assumptions examined are: (1) in a hierarchically organized lexical domain, the order of acquisition appears to be from the top of the…

Written in 1973, the document describes the application of Jean Piaget's pedagogical principles to an elementary and secondary social studies curriculum: Social Encounter and Research Curriculum for Humanization (SEARCH). In Part I, it is stressed that SEARCH is the first innovative curricular program that strives to teach the major concepts of…

This paper reviews studies in which scores on Piagetian tests of logical thought were correlated with IQ, mental age (MA) and chronological age (CA), and examines the possible effects of the size of the age range and mean age of subjects on these correlations. The data included 44 groups of subjects obtained from 36 studies in which Piagetian and…

This report is the 2-year followup evaluation of a proposed 4-year grant, studying the effects of a sequential learning program on disadvantaged children. Four- and 5-year-olds (N=86) were matched on several developmental variables, with one group at each age entering the Learning to Learn Program at either the nursery or kindergarten level. The…

Results of several studies of cognitive and cultural correlates and determinants of early IE development are discussed, and some implications of the findings are pointed out. In studies of correlations between IE and intelligence test scores, results show that the scores increase regularly with age, from age 4 through 8, and there are fairly…

A twenty-six-month follow-up study was made of 75 Anglo- and Spanish-American primary school children who were examined on the Wechsler Intelligence Scale for Children, the Illinois Test of Psycholinguistic Abilities, and the Bender Visual-Motor Gestalt Test in order to determine the specific cognitive deficits which might account for the poor…

This document is an English-language abstract (approximately 1,500 words) of a book containing the results of many years of experimental research aimed at ascertaining the intellectual ability of students in the junior grades to assimilate theoretical knowledge. Chapter one analyzes the problem of the age peculiarities of children. The author…

This paper examines evidence supporting the hypothesis that environment differentially affects intelligence in a sex-specific manner. The current position that environment and heredity contribute interactively to intelligence obscures the greater vulnerability and exposure of males to environmental influences and the reciprocal lack of equivalent…

Performance data for 42 subjects pertaining to seven course objectives and ten propositional logic tasks were analyzed for hierarchical relationships using ordering theoretic technique. The resulting hierarchy indicated that simple implication and particular contraposition propositional logic tasks were prerequisite to some course objectives. This…

Cognitive style identifies the ways individuals react to different situations. Cognitive styles include stable attitudes, preferences, or habitual strategies that distinguish the individual styles of perceiving, remembering, thinking, and solving problems. Intended for researchers, psychologists, child development specialists, and early childhood…

Describes a set of Science Reasoning Tasks which are valid and reliable for assessing the ability of children to use concrete and formal reasoning strategies and can be used by science teachers without professional training in Piagetian studies. Thirty pupils can be tested on each task in about 50 minutes. (Author/DS)
