Background &aims: Language abilities of autistic children and children at elevated likelihood for autism (EL-siblings) are highly heterogeneous, and many of them develop language deficits. It is as of yet unclear why language abilities of autistic children and EL-siblings vary, although an interaction of multiple influential factors is likely…

Socialization is the process of learning to be a human being that is born with the potential to be human. In this process, the person learns the basic values and norms of the society in which he lives, as well as the skills necessary to sustain his life. This learning takes place through parents, siblings, relatives, neighbors, peers, teachers,…

From an early age, most children choose to play with toys typed to their own gender. In order to identify variables that predict toy preference, we conducted a meta-analysis of observational studies of the free selection of toys by boys and girls aged between 1 and 8 years. From an initial pool of 1788 papers, 16 studies (787 boys and 813 girls)…

Many young children in low- and middle-income countries (LMICs) face heightened risk for experiencing environmental adversity, which is linked with poorer develop- mental outcomes. Children's stress physiology can shed light on why children are differentially susceptible to adversity. However, no known studies have examined whether links between…

Children's early social experiences shape their developing neurological and biological systems for good or for ill, writes Ross Thompson, and the kinds of stressful experiences that are endemic to families living in poverty can alter children's neurobiology in ways that undermine their health, their social competence, and their ability…

Background: Little is known about the nature, range and prevalence of different subgroups in language trajectories extant in a population from 4 to 11 years. This hinders strategic targeting and design of interventions, particularly targeting those whose difficulties will likely persist. Methods: Children's language abilities from 4 to 11 years…

The purpose of this research paper is to find a correlation between peer, genetic, and environmental influences and the behavior and personality development during childhood. This study focuses on the 1999 Columbine High School Massacre to try to explain certain kinds of behavior. The study made on 275 freshmen at Cornell University showed that…

Initial progress has been made in the conceptualization and study of attachment stability over time, and substantial evidence has accumulated on the association between attachment classification and biopsychosocial functioning (including social-emotional competence, cognition, physical health and mental health). The literature supports the…

The author considers cerebral dominance and brain asymmetry, the development of the cerebral cortex and examples of aberrancy, and diseases of the immune system, all of which relate to recent anatomical and epidemiological findings in developmental dyslexia. These discoveries have led to testable hypotheses which may enhance current understandings…

This paper focuses upon the developmental role of rough and tumble (R&T) play with particular attention to the narratives that children use to underpin such activities. A review of the literature suggests that current early years research and practice pays scant attention to children's outdoor free play activities. A piece of original research is…

The introduction to this special issue on nature-nurture interactions notes that the following articles represent five biologically oriented research approaches which each provide a tutorial on the investigator's major research tool, a summary of current research understandings regarding language and learning differences, and a discussion of…

Considers evidence on the criteria and characteristics of critical period phenomena with respect to endogenous and exogenous influences. Describes and evaluates methodology of critical period research and discusses past attempts at subclassification of the field and "recovery of function" as a refutation of the critical period…

The matrix of pre- and perinatal biological and sociocultural correlates are reviewed in relation to infants who are subsequently identified as gifted. (Author/CL)

Presents information from neuroscience which suggests that intelligence has a biological basis and may be physiologically identifiable in the future, noting that the critical time frame for intervening with gifted children may be even earlier than age 1-3 years, and adjustments may be needed to accommodate the precocious developmental time line…

Research on early development is moving apace. Developmental psychology is again giving serious attention to ages and stages. This attention is due, in great part, to the formulations about cognitive development by Piaget. Earlier in the century, the experimental approach to child study came to reflect psychology's generally heavy commitment to…
