In this article, a theoretical model of the role of parental intrusiveness in the development of childhood separation anxiety disorder is presented and tested. Parents who act intrusively tend to take over tasks that children are (or could be) performing independently, thereby limiting mastery experiences and inducing dependence on caregivers.…

This report presents findings supporting the hypothesis of a clinically relevant subtype of childhood speech sound disorder, provisionally titled speech delay--developmental psychosocial involvement (SD-DPI). Conversational speech samples from 29 children who met inclusionary criteria for SD-DPI were selected from a case record archive at a…

Many early childhood professionals recommend the use of learning centers in classrooms for young children (Kostelnik, Soderman, & Whiren, 2004). Centers provide children with opportunities for making choices, working with others, being involved in hands-on activities, and becoming fully engaged in learning. In contrast, traditional classroom…

In this year's Distinguished Educator department, we feature six educators whose research has focused on the role of early literacy in early childhood education. Each of the six addresses a vitally important aspect of early childhood literacy teaching and learning. Sections include: "Working with Families as Partners in Early Literacy," by Dorothy…

Using nonword repetition tasks as an experimental approach with both adults and children has become quite common in the past 10 to 15 years for studying lexical learning and phonological processing (e.g., Bailey & Hahn, 2001; Gathercole, Frankish, Pickering & Peaker, 1998; Munson, Edwards, & Beckman, 2005; Storkel, 2001; Vitevich & Luce, 2005). In…

The infant-toddler years are incredibly important in producing a nation of readers. Every family can, in culturally appropriate ways, help infants and toddlers learn to read the world. Every caregiver can, in culturally appropriate ways, help infants and toddlers grow in language and literacy. The authors argue that early childhood programs must…

Both clinical and laboratory studies demonstrate that seizures early in life can result in permanent behavioral abnormalities and enhance epileptogenicity. Understanding the critical periods of vulnerability of the developing nervous system to seizure-induced changes may provide insights into parallel or divergent processes in the development of…

Studies on human patients and animal models of disease have shown that disruptions in prenatal and early postnatal brain development are a root cause of mental retardation. Since proper brain development is achieved by a strict spatiotemporal control of neurogenesis, cell migration, and patterning of synapses, abnormalities in one or more of these…

Positron emission tomography (PET) is a technique that enables imaging of the distribution of radiolabeled tracers designed to track biochemical and molecular processes in the body after intravenous injection or inhalation. New strategies for the use of radiolabeled tracers hold potential for imaging gene expression in the brain during development…

This article discusses issues in measuring lexical diversity, before outlining an approach based on mathematical modelling that produces a measure, D, designed to address these problems. The procedure for obtaining values for D directly from transcripts using software (vocd) is introduced, and then applied to thirty-two children from the Bristol…

In Sweden most of the young children are in preschool from early years. The government has taken responsibility by introducing different reforms such as child allowance, maternity leave, access to preschool for all children etc. Preschool (in Sweden for children aged 1-5 years and preschool class for 6 years old) is, since 1998, the first step in…

Prematurity and low birth weight (LBW) are two major biological factors that put infants and young children at high risk for developmental delays or disabilities. While survival rates for premature and LBW children have improved, incidence figures have changed little over the past 20 years; in fact, the incidence of LBW has increased. Although the…

The scientific study of child witnesses has influenced both developmental science and jurisprudence concerning children. Focusing on the author's own studies, 4 categories of research are briefly reviewed: (a) children's eyewitness memory and suggestibility; (b) memory for traumatic events in childhood; (c) disclosure of child sexual abuse; and…

This article takes issue with the behavior-genetic analysis of parenting style presented by M. McGue, I. Elkins, B. Walden, and W. G. Iacono. The author argues that the attribution of their findings to inherited genetic effects was without basis because McGue et al. never indicated how those genetic effects manifested themselves. Instead, McGue et…

Changing times and postmodern perspectives have disrupted the taken-for-granted relationship between child development knowledge and the preparation of early childhood teachers. Despite ongoing exchanges about how best to respond to the critique of the developmental knowledge base, few descriptions of how particular teacher educators have gone…
