Relations between children's peer play competence and other relevant competencies were investigated using two samples of urban Head Start children. Dimensions of peer play were examined concurrently with emotion regulation, autonomy, and language. Children exhibiting high levels of peer play interaction were found to demonstrate more competent…

The seven cohort studies of the relation between prenatal and postnatal exposure to polychlorinated biphenyls (PCBs) to cognitive, neuropsychological and behavioral development have suggested that exposure to PCBs can cause persistent changes in cognitive functioning. D.V. Cicchetti, A.S. Kaufman, and S.S. Sparrow (this issue) apply six scientific…

In this paper we address the points raised by groups of scientists who were invited to respond to our initial critique of polychlorinated biphenyl (PCB) research in this special issue. In that article, we applied six objective criteria to more than two decades of published PCB research and concluded that much of the research was badly flawed. The…

The explosion in the rate of multiple births has led to new questions about how adequately prepared parents are for the demands of raising triplets and the implications for the healthy development of the infants. The authors examined the relationship between mothering, infant social behavior, and cognitive development in a longitudinal study of 23…

This study investigates young children's humourous activity as a form of play and considers the implications on their cognitive development and learning. The study was conducted in an infant room of a university based group child care center and multiple qualitative data collection methods were used. The findings of this study suggest that during…

This longitudinal study examined the extent to which dimensions of infant negative temperament in the first year predicted IQ at age 3, and whether these associations depended on the quality of the infant-mother attachment relationship. In a sample of 63 infant-mother dyads, mothers completed Rothbart's (1981) IBQ when infants were 4 and 12…

This article outlines six primary stages of a child's development. These basic functions show the way mental capacities work together as a team. Cognitive, motor, language, emotional, and social skills act together to help the child learn to deal with the world. Helping a child through these stages and fostering these core capacities requires a…

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…

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…

Childhood abuse has been implicated in such difficulties as developmental lags, family dysfunction, social problems, and emotional distress. This paper presents a review of the empirical literature which examines the relationship between physical abuse and object relations impairment. Data in the literature were commonly derived from either…

This book articulates and defends the "theory theory" of cognitive and semantic development: the idea that very young children just beginning to talk are engaged in profound restructurings of several domains of their knowledge. These restructurings are analogous to theory changes. The children's early semantic development is closely tied…

The phenomenon known in cognitive psychology as U-shaped behavioral growth is discussed in relation to second language learning. The U-shaped growth concept focuses on the fact that some behaviors appear, disappear, and then apparently reappear over time. It has been documented in children's learning of physical concepts, musical concepts,…

Focusing on the development of systematic observation procedures, this document provides guidance in choosing methods to assess the development of children within an early childhood program. The document discusses how to use observation data to guide decisions about curriculum and teaching, provide feedback on educational and developmental…

In the past 25 years, there has been an explosion in research on the development of perception. The research has produced discoveries at multiple levels: ecological analyses, models of representation and process, and improved understanding of biological mechanisms. This book provides a comprehensive treatment of infant perception, bringing…
