This study investigates the relationships of domain-general cognitive abilities and domain-specific verbal and mathematical abilities to students' educational characteristics when two theoretically grounded, but competing structural models are applied. In the standard model, a single latent ability causes interindividual differences in the…

Described in the context of a computer simulation are highlights of a program of research focusing on the storage of mathematics problem solving information in young children's memory and the development of such knowledge structures in older children. Specifically discussed are the problem size effect, the network nature of the memory…

Addresses the utility of a noninvasive measure of cardiac vagal tone in predicting developmental outcome among infants at risk for cognitive disabilities. Results suggest that measurement of cardiac vagal tone may provide an important means for assessing risk in birth-stressed populations. (Author/RH)

Comparison of 72 middle and 72 low socioeconomic status (SES) families of infants with developmental disabilities, on measures of maternal stress and infant development, found that regression analyses predicted 81% of the variance in later developmental level from initial Bayley Mental Age, initial Mental Development Index, SES, initial maternal…

This study addressed the extent to which performance on selected verbal and nonverbal measures contributed to the prediction of inflection learning with 20 normal boys (ages 4 to 5). Results suggested that inflection learning may be tied more to other language abilities than to nonverbal cognitive skills in normally developing boys. (DB)

Studies the effect of intellectual development, degree of field independence, mental capacity, amount of prior genetics knowledge and amount of fluid intelligence on reading comprehension and/or genetics achievement of students enrolled in a nonmajor biology course. Concludes that developmental level was the most consistent predictor of…

To investigate the factors determining why some children succeed at certain intellectual tasks while others of equal or near equal IQ, age, and motivation are unable to master the same task, 145 female and 144 male eighth grade students were administered "An Inventory of Piaget's Developmental Tasks" (IPDT). Labeled as concrete,…

This study examined the relationship among language proficiency, behavior problems, and other areas of development in 36 children (ages 36 to 40 months). A strong association was found between deficiencies in both expressive and receptive language and behavioral difficulties. Specifically, deficits in expressive language at age 2 were more…

Describes a study designed to determine if college students' success in writing computer programs is related to level of cognitive development as described by Piaget, verbal ability, and mathematics reasoning. Regression analysis showed that level of cognitive development, when combined with verbal reasoning, is linearly predictive of programming…

Designed to determine whether computer-assisted instruction could enhance performance on Piagetian classification and conservation tasks, this study divided 44 preschool children into an experimental group, which was exposed to computer lessons, and a control group. Both age and computer exposure were found to be significant variables. (LRW)

This study examined factors that affect student learning and growth in four student populations: seniors who began as freshmen immediately after high school, students who transferred from two-year colleges, students who transferred from four-year colleges, and students who entered Bachelor of Arts programs after military service or work. The data…

A cumulative risk model was used to examine the relationship among failure-to-thrive (FIT), maltreatment, and four aspects of children's development (cognitive performance, adaptive functioning at school, classroom behavior, and behavior at home) in 193 6-year-olds. Risk status was negatively associated with the four developmental outcomes.…

With over half the nation's infants and toddlers in regular, non-parental child care, the quality of that care is a priority concern for policymakers. Many studies show that high-quality child care supports the positive social, emotional, and cognitive development of young children. The research summarized in this policy brief identifies factors…

The results, which contrasted markedly with findings of major group differences at 12 months of age, indicated that by age two no group differences were apparent on any child development, mother-child interaction, or maternal attitude measures, except that preterms were significantly poorer in motor skills than were full-term infants. (RH)

Uses test questions from the Basic Economics Test (BET) to reveal that elementary students are capable of understanding economics concepts. Maintains that neither ethnic background nor parental income makes a difference in economic learning. The most statistically significant determinant of improved scores was the extent to which a concept was…
