Ability-grouping has been studied extensively in relation to children's academic, but not emotional and behavioral outcomes. The sample comprised 7259 U.K. children (50% male) with data on between-class and within-class ability-grouping at age 7. Peer, emotional, hyperactivity, and conduct problems were measured at ages 7, 11, and 14 years.…

This article investigates the influence of wealth, a frequently neglected aspect of the economic circumstances of families, on children's development. Using the UK Millennium Cohort Study, it explores whether parental wealth (net total wealth, net housing wealth, net financial wealth, and house value) is associated with children's cognitive…

Whether and to what extent kindergarten children's executive functions (EF) constitute promising targets of early intervention is currently unclear. This study examined whether kindergarten children's EF predicted their second-grade academic achievement and behavior. This was done using (a) a longitudinal and nationally representative sample (N =…

A critique of research examining whether early experiences with primary caregivers are reflected in adaptation is that relevant longitudinal studies have generally not employed genetically informed research designs capable of unconfounding shared genes and environments. Using the twin subsample (N = 485 pairs) of the Early Childhood Longitudinal…

The prospective relationships of conduct problems and peer coercion and deviancy training during kindergarten (mean age = 5.3 years) to overt and covert conduct problems in third-fourth grade were examined in a sample of 267 boys and girls. Coercion and deviancy training were distinct peer processes. Both were associated with earlier child conduct…

Two models of vulnerability to socioenvironmental risk were examined in 337 African American children (M = 7.8 years) recruited to overrepresent prenatal alcohol or cocaine exposure: The cumulative risk model predicted synergistic effects from exposure to multiple risk factors, and the fetal patterning of disease model predicted that prenatal…

The study attemped to link cognitive and social problems seen in girls with Turner syndrome by assessing the girls' ability to process affective cues.

Examined the association of neighborhood characteristics on competencies of Canadian preschoolers. Found that verbal ability positively related to residing in neighborhoods with affluent residents and negatively to residing in neighborhoods with poor residents and in neighborhoods with low cohesion, even after controlling for family SES. Behavior…

The relation between cognitive and motor performance was studied in a sample of 378 children aged 5-6. Half of these children had no behavior problems; the others were selected for externalizing (38%) or internalizing problems (12%). Quantitative and qualitative aspects of motor performance were related to several aspects of cognition, after…

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…
