Few studies have examined the relation between maternal caloric intake during pregnancy and growth in child academic achievement while controlling for important confounding influences. Using data from the National Longitudinal Survey of Youth, the current study examined the effects of reduced prenatal caloric intake on growth in scores on the…

One hundred and ten English-speaking children schooled in French were followed from kindergarten to Grade 2 (M[subscript age]: T1 = 5;6, T2 = 6;4, T3 = 6;11, T4 = 7;11). The findings provided strong support for the Home Literacy Model (Sénéchal, M., 2002) because in this sample the home language was independent of the language of instruction. The…

Panel mediation models and fixed-effects models were used to explore longitudinal relations among parents' reactions to children's displays of negative emotions, children's effortful control (EC), and children's math achievement (N = 291; M age in fall of kindergarten = 5.66 years, SD = 0.39 year) across kindergarten through…

Although the research literature regarding language growth trajectories is burgeoning, the shape and direction of English Language Learners' (ELLs) language growth trajectories are largely not known. This study used growth curve modeling to determine the shape of ELLs' language growth trajectories across 12,248 oral narrative language samples…

Speech productions of 40 English- and 40 Japanese-speaking children (aged 2-5) were examined and compared with the speech produced by 20 adult speakers (10 speakers per language). Participants were recorded while repeating words that began with "s" and "sh" sounds. Clear language-specific patterns in adults' speech were found,…

A model of the relations among cognitive precursors, early numeracy skill, and mathematical outcomes was tested for 182 children from 4.5 to 7.5 years of age. The model integrates research from neuroimaging, clinical populations, and normal development in children and adults. It includes 3 precursor pathways: quantitative, linguistic, and spatial…

Examined relationship between emotion regulation at ages 5, 10, and 18 months, and compliance at 30 months. Found that infants with low levels of regulatory behavior were more likely to be noncompliant as toddlers. High cardiac vagal tone was related to noncompliance to toy clean-up, whereas low cardiac vagal tone was related to noncompliance to…

Activities of 28 primiparous mothers and their infants that occurred during naturalistic interactions at home were observed when infants were two and five months of age. Findings indicated that infants appeared to be flexible and plastic in their behavioral repertoires, and were influenced by their mothers. Mothers adapted to the behaviors of…

Tested prefrontal and hippocampal functions in school-aged individuals with Down syndrome (DS) compared functions with those of typically developing children individually matched on mental age. Found that hippocampal and prefrontal composite scores contributed unique variance to the prediction of mental age and adaptive behavior. Noted a…

Explores whether transactional/interactional, environmental, or developmental status models best represent growth from infancy to early childhood. Attempts to identify features of the social environment important for specific developmental outcomes. Observations of interactions between 40 mothers and their three-month-old infants were used to…

Describes a model of risk potential for developmental outcome that was based on cardiac, medical, surgical, and family stress factors in 31 children with transposition of the great arteries. All children had undergone reparative open heart surgery utilizing cardiopulmonary bypass during infancy. (Author/RH)

Studied perceptions of self-competence and task values, documenting domain-specific growth trajectories for 761 children from grade 1 through 12. Found that self- perceptions of competence and subjective task values declined as children got older, although extent and rate of decline varied across domains. Found significant gender differences in…

Proposed and tested a diathesis-stress model in which the joint forces of individual vulnerability (anxious solitude) and interpersonal adversity (peer exclusion) predict children's depressive symptoms over time. Found that anxious solitude and peer exclusion co-occur in children soon after kindergarten entry and that anxious solitary children who…

Findings yielded a comprehensive portrait of the predictive relations among children's aggressive or withdrawn behaviors, peer rejection, and psychological maladjustment across the 5-12 age period. Examination of peer rejection in different variable contexts and across repeated intervals throughout childhood revealed differences in the timing,…

Event history analysis, spanning grades 7 through 12, was used to test a developmental model of the timing of first sexual intercourse among boys at risk for delinquency. As predicted, antisocial/delinquent behavior and substance use along with early physical maturity and parental transitions predicted early onset of sexual intercourse. Anxiety…
