Child environmental health (CEH) science has identified numerous effects of early life exposures to common, ubiquitous environmental toxicants. CEH scientists have documented the costs not only to individual children but also to population-level health effects of such exposures. Importantly, such risks are unequally distributed in the population,…

Longitudinal data from a large sample of twins participating in the Netherlands Twin Register (n = 42,827, age range 3-16) were analyzed to investigate the genetic and environmental contributions to childhood aggression. Genetic auto-regressive (simplex) models were used to assess whether the same genes are involved or whether new genes come into…

Infants are curious learners who drive their own cognitive development by imposing structure on their learning environment as they explore. Understanding the mechanisms by which infants structure their own learning is therefore critical to our understanding of development. Here we propose an explicit mechanism for intrinsically motivated…

This study reanalyzes data presented by Ritchie, Bates, and Plomin (2015) who used a cross-lagged monozygotic twin differences design to test whether reading ability caused changes in intelligence. The authors used data from a sample of 1,890 monozygotic twin pairs tested on reading ability and intelligence at five occasions between the ages of 7…

Studies from both high and low-middle income (LAMI) countries have documented how being reared in poverty is linked to compromised child development. Links between poverty and development are mediated by the timing and extent of exposure to both risk factors nested under poverty and to protective influences which can attenuate the impact of risk.…

This study examined differences in kindergarten children's behavioral functioning across rural and non-rural communities, as well as explored the effect of risk in each setting (i.e., rural, nonrural) on these children's behavior. Data from 116 kindergarten students and their parents and teachers was analyzed. Multileveling modeling was used to…

Background: Despite the increased risk of depression and conduct problems in children of depressed parents, the mechanism by which parental depression affects their children's behavioral and emotional functioning is not well understood. The present study was undertaken to determine whether parental depression represents a genuine environmental…

Background: Empirical studies demonstrate that maternal sensitivity is associated with attachment security in infancy, while maternal frightening/frightened behavior is related to attachment disorganization. However, attachment disorganization is also predicted by individual dispositions in infancy. Indeed, recent studies indicate a link between…

This paper presents a new perspective on the transition from early to middle childhood (i.e., human juvenility), investigated in an integrative evolutionary framework. Juvenility is a crucial life history stage, when social learning and interaction with peers become central developmental functions; here it is argued that the "juvenile transition"…

Community violence has emerged as a major risk factor for the development of mental health problems in children and adolescents. The goal of this article is to present an ecological-transactional model of community violence as a conceptual framework for understanding the existing literature and for guiding future research on community violence…

An alternate compensatory strategy for assisting persons from disadvantaged milieus is presented. A compilation of data from different areas to support consideration of the proposal is given. The proposal is such that it provides an opportunity to control and account for many of the factors that have previously confused and confounded compensatory…

Parents are one of the most important influences in positive child and youth development, yet too many caregivers, especially those in higher risk families, fail to receive supports that would improve parenting and family functioning. By strengthening parent/caregivers and their connections to resources, communities can improve child and youth…

This paper addresses the unevenness of the existing knowledge base on development and individual differences, and presents a structural model diagraming organismic and environmental influences on development. The model identifies sets of conditions which can result in gifted performance, the development of giftedness, and the maintenance of…

Examines evidence on the effects of perinatal and postnatal factors (e.g., anoxia and child abuse) on later development to determine if causality exists. The inadequacies of current developmental models are discussed. (BRT)

This paper, which introduces the theme issue, examines the concept of children "at risk" and proposes a framework which includes not only risk but also opportunity factors in child behavior and development. A table presents 30 variables influencing human development and functioning, with associated risk and opportunity factors. (DB)
