A 2003 paper in this journal reported results from a large sample of twins assessed at 2, 3 and 4 years of age on parent-administered tests and reports of their verbal and nonverbal ability. We found clear evidence for phenotypic general cognitive ability (g) that accounted for about 50% of the variance, for modest genetic influence on g (about…

This report was prepared by the National Child Care Information and Technical Assistance Center (NCCIC) in partnership with staff from the Child Care Bureau. NCCIC compiled data reported in approved CCDF Plans and relevant attachments submitted by Lead Agencies for a selected number of questions. The information presented reflects some of the…

Over the course of the past decade, the state of Louisiana has developed several documents to articulate expectations for children's learning and development and provide guidance for early childhood educators. The experiences and skills that children develop during the early years are critically important to their success later in school. What…

In this paper we present a cross-cultural study of toddler interactions with other juveniles (1-15 years of age) in two small-scale societies, the Bofi farmers and foragers of Central Africa. This paper provides a unique perspective because child development studies have predominantly been conducted in Western industrialized settings. Most studies…

This report summarizes the roundtable "Infants and Toddlers in State and Federal Budgets: Yesterday's Choices, Today's Decisions, Tomorrow's Options" conducted by the Urban Institute, with support from the A.L. Mailman Family Foundation, on March 30, 2009. The roundtable's focus grew out of the widely perceived mismatch between sharply limited…

This brief synthesis provides a summary of intervention practices that are supported by empirical evidence for promoting adaptive social-emotional behavior of young children in group contexts (e.g., pre-K classrooms; child care settings). The focus of the synthesis is on toddlers and preschool children who are identified as having disabilities or…

Evidence-based psychosocial interventions for externalizing behavior problems in children born premature have not been reported in the literature. This single-case study describes Parent-Child Interaction Therapy (PCIT) with a 23-month-old child born at 29 weeks gestation weighing 1,020 grams, who presented with significant externalizing behavior…

Speech and language difficulties can be indicative of other cognitive, social and developmental problems. Tools used in the UK have not (1) targeted two-year-old children, (2) included both parents' reports and independent observations, and (3) simultaneously evaluated expression, understanding and speech. This cross-sectional study of two…

Background: A broad capacity for deliberate self-regulation plays a key role in emotion regulation. This longitudinal investigation from infancy to preschool age examines genotype by environment (G x E) interaction in the development of self-regulation, using molecular measures of children's genotypes and observed measures of the quality of early…

The belief that a child has to abandon his home language to learn English implies that the young brain has limited learning capacity. Early childhood teachers need to help families understand that children can learn two languages at the same time. What matters is that the infant/toddler is in an effective language-learning environment, whether it…

This article investigates the acquisition of the focus particle "auch" "also" by German-learning children. We report data from spontaneous and elicited production of utterances with the focus particle "auch" by 1- to 4-year-olds complementing earlier findings of a delayed production of the unaccented "auch" compared to the accented one. But in…

Studies 16 three-year-olds' and 17 adults' hedonic reactions to odorants by using a forced-choice procedure embedded in a simple game. Analyses revealed essentially the same pattern of preferences in both groups. In general, the odorant was a much better predictor of its hedonic quality than was the age of the subject. (RJC)

White noise generators were turned on at 75 dB at bedtime and kept on all night to treat resistance going to sleep and night wakings in one-year-old toddlers. In a multiple baseline design four sets of parents recorded duration of resistance going to sleep, number of night wakings, completed surveys of their child's feeding and sleeping patterns…

To examine interactions between young children's vocabulary size and their phonological abilities, spontaneous language samples were collected from 24-month-olds with precocious lexicons, their age mates (24-month-olds with average-sized lexicons), and their vocabulary mates (30-month-olds with average-sized lexicons). Phonological ability was…

Comorbid psychopathology and challenging behaviors often occur among persons with developmental disabilities. However, little attention to this issue has been reported in young children. In this study, individuals 17 through 36 months of age with varying diagnoses, such as intellectual disability, developmental delay, and Down syndrome, among…
