Observations of 22 preschool children with cognitive delays during home-based play, made approximately 13 months apart, found no statistically significant change for the proportion of time spent in various categorical play behaviors. Children's relative ranking on play sophistication also remained stable. Significant changes were found in…

Introduces the concepts of online and offline sampling and highlights the role of online sampling in agent-based models of learning and development. Compares the strengths of each approach for modeling particular developmental phenomena and research questions. Describes a recent agent-based model of infant causal perception. Discusses limitations…

Explores children's play as social behavior in relation to cognitive style and identifies the social factors underlying both young children's play and cognitive style. Indicates that field-dependent children participated more in social play activities, while field-independent children engaged in more nonsocial play activities. Discusses the…

Explores pediatric and child psychiatric research covering five areas of potential biological and social risk to infants and children in orphanage care, specifically, infectious morbidity, nutrition, growth, cognitive and socioaffective development, and physical and sexual abuse. Results showed that institutionalization in early childhood…

A total of 270 children from 3 ethnic groups were tested for understanding of concepts of heating and cooling. A strong horizontal decalage effect was seen, with children of all ethnic groups using more sophisticated explanations at earlier ages for heating than cooling. Implications for developmental theory are discussed. (SLD)

Presents the findings of a study that was designed to determine approaches to the content of correctional-upbringing work with limited-ability children of preschool age. Considers aspects of correctional-upbringing work with preschool age children who have abnormalities in mental development. (CMK)

A study examined theory of mind acquisition in 34 children (ages 5- 10) with deafness using four traditional false-belief tasks. Results indicate the age of the child was strongly related to theory of mind development and that the children were delayed by approximately 3 years in this cognitive developmental milestone. (Contains references.)…

Maintains that advances in the literature on perception-action development suggests that tool use may be a more continuous developmental achievement than previously believed. Suggests new research directions, including efforts to investigate the processes by which children detect and relate affordances between objects, coordinate spatial frames of…

Discusses the importance of Montessori's Practical Life exercises for building character and self-esteem, more concern for others, better understanding for academic learning, and a self-nurturing, respectful classroom community. Considers aspects of movement and silence exercises for developing the child's contemplative and reflective nature that…

Surveys constructivism and developmental psychology, including work by Piaget, Vygotsky, Bruner, Gardner, Kamii, and DeVries. Considers the influence of Montessori pedagogy on early childhood education in contrast to its neglect in professional literature. (JPB)

Examines Marilyn Zimmerman's pioneering work on the applications of Piagetian theory to the study of children's musical development. Discusses "music conservation" and addresses the Piagetian model regarding (1) the implications of the sociocultural perspective and (2) the study of musical creativity. Develops the concept of…

Discusses children's musical intuitions and two methods of meaning construction, pathmaking and mapmaking. Traces the work of one child who builds the tune Hot Cross Buns with Montessori bells and explains in detail the development. Considers educational implications. (CMK)

This article examines elementary music curricula. It presents an overview of research on childhood mental development; the importance of the early experiences of children on childhood development; the impact of environmental factors on language development; children's acquisition of music ability; enhancing elementary music curriculum; and…

Background: Fragile X syndrome is one of the world's leading hereditary causes of developmental delay in males. The past decade has witnessed an explosion of research that has begun to unravel the condition at its various levels: from the genetic and brain levels to the cognitive level, and then to the environmental and behavioural levels. Our aim…

The dramatic increase in our understanding of the brain's development throughout childhood has increased our knowledge of the significance of micronutrients, such as iron and vitamin B-12, for this development. Deficiencies of these micronutrients have been shown to have an impact on students' cognitive development. Regardless of this knowledge,…
