Major findings are reported of a longitudinal, naturalistic study of grammatical morpheme development in an aphasic child from 5;5 to 6;1. The majority of the morphemes were not acquired in the same order nor at the same mean length of utterance (MLU) levels reported for normal children. As an alternative to the normal acquisition model, based on…

This study of cognitive and perceptual development compared low SES minority urban children participating in special programs with middle SES minority urban children and with the national norms on cognitive and perceptual measures. Subjects were 169 4- and 5-year-old minority urban children attending preschools in a large city. Eighteen middle…

This study examines the longitudinal relationships between mastery motivation and differentiated measures of intellectual development assessed at 1 and 3 1/2 years of age in a sample of 35 children (21 boys and 14 girls). At one year three types of mastery motivation were assessed using structured tasks: (1) producing effects (engaging in…

This paper looks into the question of the relationship between language and thought, and in particular, various theories advanced by Soviet psychologists. These theories are to be viewed within the context of the Soviet ideological legacy which proclaims that ideas do not exist apart from language. The current Soviet position can be summarized as…

A SERIES OF STUDIES WAS CONDUCTED TO CLARIFY THE ROLE OF INTELLIGENCE IN PERSONALITY ORGANIZATION AND TO ASSESS A COGNITIVE-DEVELOPMENTAL INTERPRETATION OF IQ-PERSONALITY CORRELATIONS. THE SPECIFIC FOCUS OF THE STUDY WAS THE RELATIONSHIP OF INTELLECTUAL MATURITY TO THE DEVELOPMENT OF SEX-ROLE ATTITUDES. AGE-DEVELOPMENTAL TRENDS IN SEX-ROLE…

In a 1964 investigation of the effects of age and memory on problem solving, using subjects from age three to age nineteen, it was found that the youngest and oldest subjects performed a three-choice probabilistic task significantly different from the "middle-age" children (7 to 9 years old). The three-choice task was an apparatus with a…

In this fourth part of a study of the relevance of existing knowledge about child development to social science curriculum development, some tentative suggestions are made for incorporating some of the fundamental ideas of Piaget into a teaching strategy. The ability of children to deal with classifications on the basis of single discrete…

In investigations of decline of intellectual status with age, cross-sectional and longitudinal studies give divergent results--the former show almost universal declines in test performances among older groups while the latter often show gains. Although few structure-of-intellect (SI) factors have been explored in relation to adult ages, two kinds…

This study investigated the cognitive and behavioral functions associated with iron deficiency anemia in infants and toddlers and the short-term effects of therapy on such behaviors. Subjects were 24 iron deficient and anemic infants, 9 to 26 months old. The subjects were randomly assigned to a treatment or control group. The Bayley Scales of…

Examined were the relative effects of a number of variables, but particularly sex and field-dependence, on performance of secondary school students on Piagetian measures of formal thought. It was hypothesized that males will receive significantly higher mean scores than females on all measures; that field-independent subjects will receive…

This issue provides analytical abstracts, prepared by science educators, of research reports. Two clusters of research are investigated. The first cluster, Piagetian Studies, contains seven studies which reflect a current trend in science education. The second cluster, Inservice Education, contains two studies which examine the outcomes of…

Five elementary school groups, or cohorts, were given the Test Anxiety Scale for Children and the Lie Scale for Children on three occasions over a year's time. This paper examines the results cross-sectionally and reveals between-group, or cohort effects. The youngest and oldest cohorts displayed low anxiety. Within-group longitudinal changes did…

The paper discusses the prevalence of malnutrition in developing countries and the United States, particularly as it relates to debilitating physical and psychological disorders. Educational, social, and political factors which influence the cycle of malnutrition are described. Research on the relationship between malnutrition and intellectual…

This study investigated the question of whether young children can form response chains in problem solving. After reviewing the literature relating to chaining as a component of problem solving, the author argues that a test of chaining should be free of requirements to recall previously learned material, remember general information, or apply…

This document cautions against high expectations on the part of educators for rapid cognitive growth during middle school years--and urges a rethinking of curricular structure for those years--based upon neurological data concerning brain growth patterns. Empirical research (case studies, autopsy studies, cadaver research) conducted by Epstein has…
