In the current paper we describe the methodology and results of the Oswego study, in light of D.V. Cicchetti, A.S. Kaufman, and S.S. Sparrow's (this issue) criticisms regarding the validity of the human health/behavioral claims in the PCB literature. The Oswego project began as a replication of the Lake Michigan Maternal Infant Cohort study.…

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…

Different theories offer different factors, each of which partially explain delinquency in young people. An integrated framework incorporating these theories would provide a more complete explanation. Theories that need to be built into such a framework include social control, social learning, strain, and cognitive development theories. Data were…

The nature of professional expertise has been widely debated in the literature. However it has been examined primarily from a dichotomy of perspectives--either from an experiential or a cognitive focus, without the attempt to integrate these, and other aspects of expertise into an integrated and coherent model. This article presents the…

Home-based counseling is an incredibly demanding intervention, yet little is known about the counselors providing this important service. This study sought to profile ego development, conceptual complexity, and supervision satisfaction for 120 home-based counselors. Counselors scored at moderate levels on measures of both ego development and…

Cites studies that show that environmental effects on ability test scores and school attainment are welcomed, while ability is regarded as a social construct. Asserts that an account of cognitive socialization based on the work of Bernstein and Vygotsky would represent an advance in explaining social differences in educational attainment.…

This paper presents a selective review of the literature addressing the influence of young children's conversational environments and interactions on their psychological understanding of persons. Our dual purposes are to reveal some consensus on the current state of knowledge and to foster a programmatic approach to future research. The initial…

This article explores the nature of developmental and cognitive constructivism as it has historically been related to the early childhood curriculum. The author reflects upon her personal experience in moving from a developmental to a socio-cultural theoretical perspective as an informant to her understanding regarding the education of young…

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,…

Autism is a heritable disorder characterized by phenotypic and genetic complexity. This review begins by surveying current linkage, gene association, and cytogenetic studies performed with the goal of identifying autism disease susceptibility variants. Though numerous linkages and associations have been identified, they tend to diminish upon…

Observing young children at play is a very common and useful method for identifying the presence or absence of certain developmentally appropriate skills. Such observations can vary from general overviews of typical classroom activities to extensive and highly detailed data-collection systems. Although educators should use a series of…

Roughly 20 per cent of all students in higher education have sustained clinically significant head injuries during childhood or adolescence. Although these injuries typically do not seem to lead to any long-term intellectual deficits, little is known about their possible impact upon the students' academic attainment. Nevertheless, many…

This study focuses on the ability of deaf children to predict the behaviours of other people, based on an understanding of their beliefs. An unexpected transfer task and a deceptive box task were used with a group of 55 severely/profoundly deaf children. Results reiterate the findings of other studies that many deaf children are grossly delayed in…

The impact of school-based Tae Kwon Do training on self-regulatory abilities was examined. A self-regulation framework including three domains (cognitive, affective, and physical) was presented. Children (N = 207) from kindergarten through Grade 5 were randomly assigned by homeroom class to either the intervention (martial arts) group or a…
