Developmental scholars, parents, and policymakers alike have long heralded the opening years of life as disproportionately influential. Recent work on adolescence has revealed, however, greater influence of these later years--but without considering how experience during these two periods interact. We address this issue by studying adverse…

Evolutionary-minded developmentalists studying predictive-adaptive-response processes linking childhood adversity with accelerated female reproductive development and health scientists investigating the developmental origins of health and disease (DOoHaD) may be tapping the same process, whereby longer-term health costs are traded off for…

Data from 508 Caucasian children in the NICHD Study of Early Child Care and Youth Development shows that the DRD4 (but not 5-HTTLPR) polymorphism moderates the effect of child-care quality (but not quantity or type) on caregiver-reported externalizing problems at 54 months and in kindergarten and teacher-reported social skills at kindergarten and…

Background and methods: In two birth cohort studies with genetic, sensitive parenting, and attachment data of more than 1,000 infants in total, we tested main and interaction effects of candidate genes involved in the dopamine, serotonin, and oxytocin systems ("DRD4", "DRD2", "COMT", "5-HTT", "OXTR") on attachment security and disorganization.…

This article presents theoretical arguments and supporting empirical evidence suggesting that attachment experiences in early life may be important in the later development of self-regulation and conscientious behavior. Analyses of data from the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care and Youth…

Much research on the quality of child care reveals it--in the case of low-quality child care--to be related to poorer child functioning, net of confounding factors, perhaps especially in the case of cognitive-linguistic performance. Recent work using data from the National Institute of Child Health and Human Development (NICHD) Study of Early…

After questioning the practical significance of evidence that parenting influences brain development--while highlighting the scientific importance of such work for understanding "how" family experience shapes human development--this paper reviews evidence suggesting that brain structure and function are "chiselled" by parenting. Although the…

Background: Some contend that attachment insecurity increases risk for the development of externalizing behavior problems in children. Method: Latent-growth curve analyses were applied to data on 1,364 children from the NICHD Study of Early Child Care to evaluate the association between early attachment and teacher-rated externalizing problems…

Research on differential susceptibility to rearing suggests that infants with difficult temperaments are disproportionately affected by parenting and child care quality, but a major U.S. child care study raises questions as to whether quality of care influences social adjustment. One thousand three hundred sixty-four American children from…

Background: Inconsistencies regarding developmental effects of non-maternal childcare may be caused by neglecting the possibility that children are differentially susceptible towards such experiences. Method: Interactions between difficult/negative child temperament and childcare type, quantity, and quality on teacher-rated behavior problems and…

Background: An area-based initiative, Sure Start Local Programmes (SSLPs), was established by the UK government to reduce social exclusion through improving the well-being of children aged 0-3 years and their families in disadvantaged communities; a true community intervention in that all children under four and their families in specified areas…

Two general evolutionary hypotheses were tested on 756 White children (397 girls) studied longitudinally: (1) rearing experiences would predict pubertal timing; and (2) children would prove differentially susceptible to rearing. Analysis of pubertal measurements, including some based on repeated physical assessments, showed that mothering and…
