During birth to 2 years, babies are motivated by an innate need to know about things. At 3 to 4 years, children tend to wonder about a lot of things. They wonder about scary things, how things work, nature, origins, and the world around them. At 5 to 6 years, they tend to increase their awareness, observe and notice a lot of differences. The…

Researchers who advocate the hypothesis that cognitive development is akin to theory formation have also suggested that young children possess distinct systems for explaining physical, psychological, and biological principles (see, e.g., Wellman & Gelman, 1992). One way this has been investigated is by examining how children explain human action:…

The experiment reported here investigated infants' concept of intention, as well as the relation among intention understanding, general productive vocabulary, and internal state language production during the 2nd year. Results from an imitation task indicated that 18-month-olds are better able to differentiate between intentional and accidental…

Although thermal conditions influence the development of living organisms in a wide variety of ways, this topic has been recently ignored in humans. This paper reintroduces thermal conditions as a topic of importance for developmentalists by presenting an example of how thermal conditions are hypothesized to influence a particular developmental…

The National Institute of Child Health and Human Development (NICHD) and the National Council for Accreditation of Teacher Education (NCATE) collaborated to produce a summary of two roundtable discussions on the critical relevance of child and adolescent development research to teacher preparation practices. The participants in the roundtable…

There is increased interest by parents in communicating with their children about political violence. However, limited attention in the scholarly literature has focused on parent-child communication about war and terrorism. In response, the purpose of this study is to assess, within their respective ecological contexts, American and Northern Irish…

Since the creation of "Sesame Street", children's educational television programs have grown in both number and popularity. However, controversy has shadowed the children's television arena for many years. Some have claimed that viewing television is a passive event, requiring little or no effort on the part of the viewer. However, research on…

During a career spanning five decades, Edward Zigler has combined scholarly research with public service to promote national and state policies that are good for all children. Often called "the father of Head Start," he served on the planning committee for the program in 1965 and became the first director of the Office of Child…

We explore the immediate and longer term consequences of different types of instruction about a central topic in middle school science: the "Control of Variables Strategy" (CVS). CVS represents the procedural and conceptual basis for designing simple, unconfounded experiments, such that unambiguous causal inferences can be made. CVS…

Five papers are presented from a 1982 conference on "Developmental and Clinical Aspects of Young Children's Play." In the first paper ("Cognitive Characteristics of Young Children's Play,") S. Rogers summarizes J. Piaget's theories on developmental stages, discusses the relationship of practice play to learning, and then…

This paper examines the theories of Herman T. Epstein, who has suggested that there may be a correlation between Piaget's stages of intellectual development and the brain growth stages. Epstein's research has indicated that the human brain grows in spurts rather than in simple linear increments across time. Of special significance to educators is…

Children and adolescents have different understandings of death. For the baby, death is equated with separation. For toddlers, grief occurs when they realize the person is not returning. The preschool child who tends to live in the present with no clear concept of past or future will not understand the finality. Around ages 4 and 5, death is often…

"More" and "less" were analyzed into two meaning dimensions, "occurence" and "quantity", which were hypothesized to be developmentally related to acts of addition and subtraction. (SBT)

This study attempted to determine the functional components of rehearsal strategies in children's discrimination learning. When a discrimination list was given without rehearsal instructions, ability to discriminate situational frequencies predicted performance. Without rehearsal strategy, subjects' ability to discriminate between previous usage…

The purpose of this study was to discover if there was a relationship in decisions made between adults and 11-year old students assumed to be at different levels of the formal operations stage in their responses to a situation calling for a moral judgment. (Author)
