Little research has considered whether prenatal experience contributes to executive function (EF) development above and beyond postnatal experience. This study tests direct, mediated, and moderated associations between prenatal risk factors and preschool EF and IQ in a longitudinal sample of 1,292 children from the Family Life Project. A composite…

This paper used the Early Childhood Longitudinal Study-Birth Cohort (N = 1,258) to examine the influence of hilevels of cognitive stimulation from mothers, fathers, and childcare providers at 24 months and children's pre-academic skills at 48 and 60 months in two parent families. Results from path analysis showed direct positive effects of…

One-quarter of the Head Start population has a mother who participated in the program as a child. This study uses experimental Head Start Impact Study (HSIS) data on 3- and 4-year-olds (N = 2,849) to describe multigenerational Head Start families and their program experiences. In sharp contrast to full-sample HSIS findings, Head Start has large,…

Guided by family risk and allostasis theoretical frameworks, the present study utilized a prospective longitudinal design to examine associations among family risk experiences, basal cortisol patterns, and cognitive functioning in children. The sample included 201 low-income children living within a midsize city in the Northeastern United States.…

The transition into school occurs at the intersection of multiple environmental settings. This study applied growth curve modeling to a sample of 1,364 American children, followed from birth through age 6, who had been categorized by their exposure to cognitive stimulation at home and in preschool child care and 1st-grade classrooms. Of special…

To study the effects of perinatal HIV-1 infection and early institutional rearing on the physical and cognitive development of children, 64 Ukrainian uninfected and HIV-infected institutionalized and family-reared children were examined (mean age = 50.9 months). Both HIV infection and institutional care were related to delays in physical and…

This article uses longitudinal data from approximately 2,000 low-income families participating in the national evaluation of the Comprehensive Child Development Program to examine the associations between preschool children's living arrangements and their cognitive achievement and emotional adjustment. The analysis distinguishes families in which…

Describes a study involving administration of a home environment inventory to a sample of 77 mothers and infants in order to explore its ability to predict later mental test performance. Correlations between home inventory data and measures of infant development over a period of 30 months were higher than those typically reported. (ED)

Results show individual differences in intelligence progressively stabilizing by school age, with each child following a distinct pattern of mental development. Monozygotic twins became increasingly concordant over an Hes and were closely matched on developmental trends. (Author/RH)

Analyzed genetic and environmental contributions to intellectual change in 258 adopted and 93 biological children of 3-14 years. The effect of genes and family environment was significant at the time of the first measurement, but only genes made an additional contribution between the first and the second. (RJC)

The Home Observation for Measurement of the Environment Inventory and the Rheingold and Cook Checklist were respectively used to assess the home environments of children whose mothers were married/working, married/nonworking, or divorced/working. (Author/MP)

A path model of genetic and shared family environmental transmission was fitted to general cognitive ability data from 1-, 2-, 3-, and 4-year-old adopted and nonadopted children and their parents to assess the etiology of longitudinal stability from infancy to early childhood. (HOD)

Assesses ability of infant tests to predict language and cognitive development and to detect infants at risk for developmental problems. The Bayley Mental Development Index was particularly capable of detecting infants at risk for developmental delay. The Caldwell Inventory of Home Stimulation identified home environment as a key factor in…

To examine the development of triplets, 23 sets of triplets were matched with 23 sets of twins and 23 singletons (N138). Maternal sensitivity was observed at newborn, 3, 6, and 12 months, and infants' cognitive and symbolic skills at 1 year. Triplets received lower maternal sensitivity across infancy and exhibited poorer cognitive competencies…

Examines possible correlates of difficult temperament by testing 152 adopted and 120 nonadopted infants at 12 and 24 months. Finds no significant relationships between parental reports of difficult temperament and other aspects of infant development, the home environment, or parental personality. Questions the utility of the construct of difficult…
