Fifty-nine healthy infants were filmed with their mothers and with a researcher at two, four, six and nine months in face-to-face play, and in toy-play at six and nine months. During toy-play at both ages, two indices of joint attention (JA)--infant bids for attention, and percent of time in shared attention--were assessed, along with other…

Emerging phonotactic knowledge facilitates the development of the mental lexicon, as demonstrated by studies showing that infants use the phonotactic patterns of their native language to extract words from continuous speech. The present study provides a computational account of how infants might induce phonotactics from their immediate language…

Atypical attention, while not a diagnostic feature, is common in individuals with autism spectrum disorders (ASD). The study of these atypicalities has recently gained in both quantity and quality, due in part to an increased focus on attentional atypicalities as one of the earliest signs of ASD in infancy. A range of attentional processes and…

The federal Early Head Start (EHS) program was created in 1994 to address the comprehensive needs of children under age 3 in low-income families and vulnerable low-income pregnant women. In addition to early learning opportunities, EHS's comprehensive early childhood development programs provide children and families with access to a range of…

The purpose of the study was to evaluate the language status of 120 young, Latino dual language learners living in poverty in the United States. Maternal language input and home language and literacy environments were examined with regard to language development at 24 and 36 months. Results suggested that even when combining English and Spanish…

Nearly half a million children in the United States are currently being served by the foster care system. Infants and toddlers represent the largest single group entering foster care. While these very young children are at the greatest peril for physical, mental health, and developmental issues and tend to spend the longest time in the foster care…

Current clinical diagnosis of Autism Spectrum Disorders (ASD) occurs between 3 and 4 years of age, but increasing evidence indicates that intervention begun earlier may improve outcomes. Using secondary analysis of the Early Childhood Longitudinal Study-Birth Cohort data set, the current study identifies early predictors prior to the diagnosis of…

This resource provides parents with widely held expectations for their child's development prior to kindergarten and ways parents can encourage their child's growth. Although a child's growth and development follows a general pattern, all children grow at different rates. Some children will be doing things earlier or later than others. There's no…

Adults experience a paucity of memories from infancy and early childhood. This childhood amnesia contributed to the impression that infants and young children lacked the ability to remember the experiences of their lives. The development of nonverbal tests of memory led to a revision of this perspective and a wealth of evidence that young children…

Navigating the social world is an extraordinarily difficult and complex task. How do we think about other people's minds, and how do we come to infer other people's intentions from their actions? Developmental psychologists have shown that even very young infants are attuned to the emotions of those around them, imitate facial expressions and…

ZERO TO THREE's executive director and members of the board offer their thoughts on working to support the healthy development of infants, toddlers, and their families over the past 30 years, and where we need to go as we look to the future.

Recognizing word boundaries in continuous speech requires detailed knowledge of the native language. In the first year of life, infants acquire considerable word segmentation abilities. Infants at this early stage in word segmentation rely to a large extent on the metrical pattern of their native language, at least in stress-based languages. In…

Using a socio-cultural lens, this study explores two unique populations participating in an intergenerational music experience: seven infants/caregivers (ages 3-16 months) and eight retired women religious (ages 70-94). I was curious to examine how music-making across ages might facilitate new-found meaning for old people whilst simultaneously…

Recent research has shown that infants as young as 13 months can attribute false beliefs to agents, suggesting that the psychological-reasoning subsystem necessary for attributing reality-incongruent informational states (Subsystem-2, SS2) is operational in infancy. The present research asked whether 18-month-olds' false-belief reasoning extends…

The capacity to engage and communicate in a social world is one of the defining characteristics of the human species. While the network of regions that compose the social brain have been the subject of extensive research in adults, there are limited techniques available for monitoring young infants. This study used near infrared spectroscopy to…
