Purpose: This study was designed to (a) identify sociodemographic, pregnancy and birth, family health, and parenting and child care risk factors for being a late talker at 24 months of age; (b) determine whether late talkers continue to have low vocabulary at 48 months; and (c) investigate whether being a late talker plays a unique role in…

This National Services Snapshot summarizes key data on demographics and services for children from birth to age five and pregnant women served by Head Start, Early Head Start, and Migrant and Seasonal Head Start programs. The data in this Snapshot is a subset of the annual Program Information Report (PIR) submission to the Office of Head Start.…

This Migrant and Seasonal Head Start (MSHS) Services Snapshot summarizes key data on demographics and services for children from birth to age five and pregnant women served by all Migrant and Seasonal Head Start programs. The data in this Snapshot is a subset of the annual Program Information Report (PIR) submission to the Office of Head Start.…

The present study was designed to examine cross-cultural differences in longitudinal links between infant temperament toddler behavior problems in the U.S. (N= 250) and Russia (N= 129). Profiles of risk/protective temperament factors varied across the two countries, with fewer significant temperament effects observed for the Russian, relative to…

To identify possible early signs of autism spectrum disorder (ASD) within the Danish National Birth Cohort, we studied prospectively collected interviews from 76,441 mothers about their children's development and behaviour at 6 and 18 months. In Danish national registries, 720 children with ASD and 231 children with intellectual disability (ID)…

Four experiments investigated whether infants and adults infer that a novel entity that interacts in a contingent, communicative fashion with an experimenter is itself an intentional agent. The experiments contrasted the hypothesis that such an inference follows from amodal representations of the contingent interaction alone with the hypothesis…

We assessed the eye-movements of 4-month-old infants (N = 38) as they visually inspected pairs of images of cats or dogs. In general, infants who had previous experience with pets exhibited more sophisticated inspection than did infants without pet experience, both directing more visual attention to the informative head regions of the animals,…

Infants in their first year manifest selective patterns of discrimination between languages and between accents of the same language. Prosodic differences are held to be important in whether languages can be discriminated, together with the infant's familiarity with one or both of the accents heard. However, the nature of the prosodic cues that…

Infants often pay special attention to speech sounds, and they appear to detect key features of these sounds. To investigate the neural foundation of speech perception in infants, we measured cortical activation using near-infrared spectroscopy. We presented the following three types of auditory stimuli while 3-month-old infants watched a silent…

This study explored whether the relationships between specific features of child care quality and externalizing and internalizing behaviors in 24-month-old children are moderated by gender and temperament. Questionnaires were used to record children's gender and measure their temperament. Child care quality was observed with the "Échelles…

Infants at risk for autism spectrum disorders (ASD) may have difficulty integrating smiles into initiating joint attention (IJA) bids. A specific IJA pattern, anticipatory smiling, may communicate preexisting positive affect when an infant smiles at an object and then turns the smile toward the social partner. We compared the development of…

Background: Animal research indicates that the neural substrates of emotion regulation may be persistently altered by early environmental exposures. If similar processes operate in human development then this is significant, as the capacity to regulate emotional states is fundamental to human adaptation. Methods: We utilised a 22-year longitudinal…

The world of infants and toddlers is a world of unflagging curiosity and discovery. They are compelled to go, with boundless energy, after the skills that they need for the future. When they are allowed to accumulate as rich and as multifaceted a bundle of formative experiences as possible, teachers expand the material that they have to construct…

Long before empirical neurological research validated her insight, Montessori understood that healthy, full-term babies come equipped with a physiological passion for learning. Brain studies have confirmed that most of the brain's development and inner wiring occurs during the first 2 years of life. A newborn's neurons have sparse, weak…

The aim of the present study was to investigate whether temperament and cognitive abilities are related to recognition performance of Caucasian and African faces and of a nonfacial stimulus class, Greebles. Seventy Caucasian infants were tested at 3 months with a habituation/dishabituation paradigm and their temperament and cognitive abilities…
