Can well-documented gender differences in evaluations of prosocial versus antisocial actions found in childhood and adulthood be traced to sex differences in basic sociomoral preferences in infancy? We provide an answer to this question by meta-analyzing sex differences in preference for prosocial over antisocial agents in a set of 53 samples of…

Speech problems affect about 66% of children with classic galactosemia (CG), but limited evidence is reported on early motor and sensory motor development in this at-risk population. Research has been focused on speech and language development, leaving a paucity of data on motor and sensory differences. This paper describes preliminary data…

Infant and toddler pedagogy has flourished as a specialized area of practice in early childhood care and education settings, yet it remains an under-researched area. There is also limited empirical research internationally that explores cultural meanings of meaningful provision for this young age group. This ethnographic study explored pedagogies…

Background: As delays or disorders in early language and communication are the most prevalent symptom in children with disabilities, early screening is crucial to promote prevention, early diagnosis, and intervention. However, to the best of our knowledge, no screening tool is available for the joint assessment of early language and social…

The annual National Deafblind Child Count is the world's first and longest-running count of children who are deafblind. Begun in 1986 on behalf of the U.S. Department of Education, it represents a collaborative effort between the National Center on Deafblindness (NCDB) and state deafblind projects throughout the country, including those in the…

Play is a central discourse in policy and practice pertaining to young children's learning, development and well-being in many countries around the world. Dominant ways of understanding and advocating for play often construct universalising notions of children and childhood, overlooking that play is always-already culturally situated and…

In order for children to understand and reason about the world in an adult-like fashion, they need to learn that conceptual categories are organized in a hierarchical fashion (e.g., a dog is also an animal). While children learn from their first-hand observation of the world, social knowledge transmission via language can also play an important…

Homelessness is a traumatic experience with long-term consequences, particularly for infants and toddlers in their most critical stages of development. Yet homelessness among young children is hidden. Lack of shelter, fear of having children removed from parental custody, and restrictive eligibility criteria for housing programs mean that most…

Infants and toddlers (birth to age 3) learn what it means to be members of, and to belong to and be accepted by, their societies by adopting behaviors, attitudes, manners, and ways of thinking that are deeply rooted in what is valued in their culture. Infant and toddler teachers play a pivotal role as transmitters and maintainers of culture when…

Policymakers, child care providers, and parents face tradeoffs in determining how much to spend on child care, including how many hours to purchase, and the features of programs that might influence quality. Given these tradeoffs, it is useful to understand what constitutes quality, the cost of care features associated with quality, the effects of…

Certain social context features (e.g., maternal presence) are known to increase young children's exploration, a key process by which they learn. Yet limited research investigates the role of social context, especially peer presence, in exploration across development. We investigate whether the effect of peer presence on exploration is mediated by…

Studies on the relationship between bookreading and language development typically lack data about which books are actually read to children. This paper reports on an Internet survey designed to address this data gap. The resulting dataset (the Infant Bookreading Database or IBDb) includes responses from 1,107 caregivers of children aged 0-36…

Is income during children's earliest years a key determinant of long-term child and adult success in the longer run? The research to date, Christopher Wimer and Sharon Wolf write, suggests that it is. Wimer and Wolf review substantial descriptive evidence that income can enhance child development and later adult outcomes, and that it does so most…

While most early childhood education and care (ECEC) programs taken to scale in the United States have served socially disadvantaged 3- to 5-years-olds, Norway scaled up universal ECEC from age 1. We investigated the consequences of Norway's universal ECEC scale-up for children's early language skills, exploiting variation in ECEC coverage across…

We discuss oral history interviews with academics who laid the foundation of research and pedagogies in daycare for under three-year-olds in Europe and North and South America since the 1970s. Their work is clearly embedded in the social-political context of their country: the left-wing programmes for disadvantaged families in the U.S.A.;…
