Reviews selected research on children's early formation of categories. Finds sophistication in how children group objects and think about those groupings. Notes findings related to type of grouping (thematic or taxonomic), multiple classifications, overgeneralization, the role of background knowledge on classification abilities, the…

Discusses the importance of science education in early childhood education and describes different approaches in incorporating physics into the preschool curriculum. Provides examples of experiments and encourages parent participation in children's science activities. Concludes by looking at science as an equity issue and emphasizes that science…

Presents six articles on brain research and child development: "Brain Research, Infant Learning, and Child Care Curriculum" (J. R. Lally); "The Thinking Brain" (P. Schiller); "Early Experiences Shape Social Development" (B. Caldwell); "Facing the Challenge of Motor Development" (P. Weikart); Language…

Two studies examined developmental outcomes associated with services in inclusive and self-contained preschool classrooms. Children functioning at relatively higher levels of social and emotional functioning performed better in inclusive settings than in specialized settings and children in full-day classrooms achieved higher rates of progress…

Considers the implications of nonparental care for cognitive development and behavior problems in Swiss young children. Finds that the effect of nonparental care on behavior problems was mediated by the pattern of attachment to the mother and that the effect on cognitive development was mediated by the quality of care.

Interviews with 47 Mexican-American children in grades 2 and 6 and their parents revealed that parental ethnic socialization about ethnic discrimination was associated with children's development of ethnic knowledge. Children's understanding of ethnic prejudice was related to their ethnic knowledge but not their ethnic behaviors. Contains 24…

This study investigated families of children with autism spectrum disorders using early intervention and early childhood services, as well as the perceived efficacy and developmental outcomes related to the services and service delivery methods. Results indicated that a variety of recommended practices are not being used by families and…

Our purpose in this report is to evaluate scientifically that body of literature relating the effects of prenatal and postnatal exposure to polychlorinated biphenyls (PCBs) upon neurobehavioral, health-related, and cognitive deficits in neonates, developing infants, children, and adults. The data derive from seven cohorts: six cohorts of mothers…

Inflammation during the perinatal period has become a recognized risk factor for developmental brain injuries over the past decade or more. To fully understand the relationship between inflammation and brain development, a comprehensive knowledge about the immune system within the brain is essential. Microglia are resident immune cells within the…

Successful treatment of many childhood diseases once considered terminal has resulted in the emergence of long-term effects of the disease or consequences of treatment that were previously unrecognized. Many of these long-term effects involve the central nervous system (CNS) and are developmental in the way that they emerge over time. Because we…

Due to the relatively late age of clinical diagnosis of autism, the early brain pathology of children with autism has remained largely unstudied. The increased use of retrospective measures such as head circumference, along with a surge of MRI studies of toddlers with autism, have opened a whole new area of research and discovery. Recent studies…

Standardized clinical assessments from the point of view of children are rare. A standardized narrative assessment measure, developed to assess children's perceptions of their caregiving environments, the Narrative Story-Stem Technique (NSST), was used with two fraternal twins, age 8, with histories of severe maltreatment and multiple foster…

This policy brief explores kindergarten readiness observation and its benefits to local and state level stakeholders; highlights efforts by California counties and other states to measure school readiness; and makes recommendations for moving toward statewide use of kindergarten readiness observation tools. Key points include: (1) Early efforts to…

School readiness tests are significant predictors of early school achievement. Measuring school readiness on a large scale would be necessary for the implementation of intervention programs at the community level. However, assessment of school readiness is costly and time consuming. This study assesses the predictive value of a school readiness…

Objective: To examine how maternal depressive symptoms are related to infant development among low-income infants in rural Bangladesh and to examine how the relationship is affected by maternal perceptions of infant irritability and observations of caregiving practices. Methods: Development was measured among 221 infants at 6 and 12 months with…
