Changes in intelligence among Swedish 13-year-olds during a 20-year period was studied. Results show: (1) the average of spatial and reasoning intelligence has risen; (2) verbal intelligence increased during the 1960s, but declined thereafter; and (3) by the 1980s girls surpassed in verbal ability and equalled in spatial ability.

Assessed the quality of home and out-of-home care environments, child temperament, and the development of verbal abilities among infants at 18 months and then at 8 years of age. Found that both tested and rated cognitive abilities at age 8 were related to earlier measures of verbal ability and to paternal involvement during preschool years. (MOK)

A study designed to examine biological, sociological, and early maturational correlates of intelligence collected data prospectively, from birth to 15 years of age, on a sample of 987 black children. Multiple indicators of eight independent and three dependent variables were tested in a structural equation model. Altogether, clear sex differences…

The major issue investigated in this paper is whether or not any change appears over a five-year peiod in the differences in performances between minority and non-minority students in that district. Since the relative performance advantage of non-minority students is frequently ascribed to their better backgrounds, socio-economic factors are held…

Identified groups of economically disadvantaged children showing high externalizing behavior in first grade that persisted (persistent) or decreased (improver) in third grade, or low first- grade levels that were stable (unproblematic) or increased (new problem) in third grade. Found that verbal ability, behavioral impulsivity, parent…

Longitudinal study of mathematics achievement and gender of (n=60) students progressing from 6th to 12th grade found consistent gender differences in stereotyping mathematics as a male domain; identified no difference in spatial, verbal, or mathematics skills; and found positive correlation between achievement and confidence. (17 references)…

Describes the design and findings of the Victoria Day Care Research Project. Concludes that early day care experiences and family environments were associated with verbal abilities in early childhood and with competencies in early and late adolescence. Found that children from higher-resource families were most likely to have higher-quality day…

Research is examined on learning and memory from text across the adult life span. The outcomes of the extant studies are contradictory. Clarification of these confusing findings is obtained by examining variations in the learner variables of education level and performance on vocabulary tests. Problems are considered in equating the learner…

STUDIES OF CREATIVITY AND OF PSYCHOLOGICAL DISTURBANCES IN CHILDREN HAVE SUGGESTED THE PRESENCE OF SLUMPS (OR INVERSIONS) WHICH MAY BE CORRELATED WITH DEVELOPMENTAL TRANSITIONS. THE MOST NOTABLE OF THESE OCCURS AT ABOUT THE FOURTH GRADE AND IS THE OBJECT OF THIS STUDY. THREE SETS OF INVESTIGATIONS WERE UNDERTAKEN--(1) A STUDY OF CREATIVE…

Genetic involvement in specific verbal and spatial abilities and memory and perceptual speed was assessed using 163 adopted and 142 non-adopted 7-year-olds and their biological, adoptive, and non-adoptive parents. Results imply the existence of some genetic continuity from the early school years to adulthood for verbal and spatial abilities. (TJH)

This study investigated the sustained effects of Project Head Start for disadvantaged, black children in kindergarten and first grade. Participation in Head Start was compared to other forms of preschool experience and no preschool experience for disadvantaged children in two American cities in 1969-1970. Both preprogram background and cognitive…

IN THE LONGITUDINAL BERKELEY GROWTH STUDY, SUBJECTS WERE TESTED AT 16, 18, 21, AND 26 YEARS ON THE WECHSLER-BELLEVUE, AND AT 36 YEARS ON THE WECHSLER ADULT INTELLIGENCE SCALE, WHICH CONTAIN BOTH VERBAL AND NON-VERBAL SUBSCALES. THE MOST CONSISTENT INCREASES IN MEAN SCORES OVER THE PERIOD WERE IN INFORMATION, VOCABULARY, AND COMPREHENSION. DIGIT…

Changes in verbal, spatial, and reasoning intelligence among Swedish 13-year olds were studied from 1960 to 1990. Rising verbal scores until 1980 have been followed by a decline to essentially the 1960 level. Spatial and reasoning results have risen continuously. Gender and social class differences are discussed. (SLD)

This segment of the national evaluation study of the Follow Through Planned Variation Model presents an analysis of the longitudinal effects of Follow Through program models and a study of Follow Through children who were identified as being at academic risk. The longitudinal analysis examines three dimensions of program effects: (1) differences…

This study investigated possible changes in verbal, spatial, and reasoning intelligence in Swedish 13-year-olds over a 20-year period. The first sample included about 12,000 students born in 1948. Data consisted of (1) information from school records, (2) information on personal background, (3) scores on three intelligence tests and three…
