Healthy brain development relies on the quality of early relationships. Supportive relationships and parent-child conversations buffer stress; they contribute to the cognitive and emotional stimulation that developing brains need; and the quality of parent-child conversation is important even before young children are good conversational partners.…

To reduce risk factors for adult disease in our society, we must tackle the problem of toxic stress in early childhood. This condition is associated with the excessive release of a stream of hormones whose persistent elevation can disrupt the wiring of the developing brain and the functioning of the immune system. Children who experience toxic…

Studies indicate investments in social programs that raise a poor working mother's income may be especially beneficial to her children when they are of preschool age. Other studies show that high-quality preschool education interventions can have long-term beneficial impacts on school dropout, lifetime earnings and incarceration rates for…

A case study of Nebraska early childhood legislation, passed unanimously in 2005, shows the role of science in effective policymaking. By combining citizen advocacy, skillful work by legislators, and testimony by local experts as well as national scientists, Nebraska succeeded in producing bipartisan consensus on the importance of early childhood…

The field of developmental psychology offers new insights into the link between the quality and nature of early relationships with caregivers to the healthy social, emotional, and cognitive development of young children. Three dimensions of child care seem to make the most difference: the interactions between young children and their caregivers,…

By bringing together neurologists, developmental psychologists, pediatricians, and economists, the National Scientific Council on the Developing Child offers a unique knowledge base from which early childhood policy and practice can be informed. By communicating how and why early experiences have a lasting impact on brain architecture--and what…

Recent advances in developmental science can teach us a great deal about the value of specific kinds of human interactions in the earliest years of life for the developing brain architecture. Animal experiments indicate that enriched environments with opportunity for frequent interaction and new experiences can help the animals' brains develop…

In 2006, the input of scientists, economists, and private industry representatives inspired nearly unparalleled bipartisan support in Washington state for the formation of a Department of Early Learning. This new cabinet-level department consolidates three separate agencies, provides universal preschool for all children in Washington, and…

Leading economists conclude that investments in young children may be the best way to stimulate economic growth, and investments in young children's social and emotional development may be the most productive of these investments. The science base for these conclusions comes from two independent streams of research: neuroscience and developmental…

A growing body of scientific evidence demonstrates that emotional development begins early in life and is closely connected with the emergence of cognitive, language and social skills. Early emotional development lays the foundation for later academic performance, mental health, and the capacity to form successful relationships. Despite this…

This science brief reports on a study that identified the effects of different experiences on critical periods of learning during early brain development. The study found that the presence of corticosterone in a part of the brain called the amygdala determined whether a normally painful experience was learned as an attractive or fearful event.…

Recent advances in neuroscience show clearly how experience can change brain neurochemicals, and how this in turn affects the way the brain functions. As a result, early negative events actually get built into the growing brain's neurochemistry, altering the brain's architecture. Research is continuing to investigate how children with genetic…

New science shows that exposure to toxins prenatally or early in life can have a devastating and lifelong effect on the developing architecture of the brain. Exposures to many chemicals have much more severe consequences for embryos, fetuses, and young children, whose brains are still developing, than for adults. Substances that can have a truly…

Early experience has a powerful and lasting influence on how the brain develops. The physical and chemical conditions that encourage the building of a strong, adaptive brain architecture are present early in life. As brains age, a number of changes lock in the ways information is processed, making it more difficult for the brain to change to other…

"Science Briefs" summarize the findings and implications of a recent study in basic science or clinical research. This Brief summarizes the findings and implications of "Exposure to Repetitive versus Varied Stress during Prenatal Development Generates Two Distinct Enxiogenic and Veuroendocrine Profiles in Adulthood" (H. N. Richardson; E. P.…
