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…

Whether high quantities of center-based care cause behavior problems is a controversial question. Studies using covariate adjustment for selection factors have detected relations between center care and behavior problems, but studies with stronger internal validity less often find such evidence. We examined whether within-child changes in hours in…

The benefits afforded to young children through shared reading are well-documented, but few studies have focused on what contributes to enjoyment of shared reading, especially as it pertains to caregivers' enjoyment. This study explored child and caregiver enjoyment of shared reading through an online survey. Caregivers named books their 0- to…

Two experiments examined the development of the ability to encode, maintain, and update integrated representations of occluded objects' locations and featural identities in working memory across toddlerhood. Sixty-eight 28- to 40-month-old US toddlers (13 Asian or Pacific Islander, 6 Black, 48 White, 1 multiracial; 40 girls; tested between…

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…

Around the world, musical engagement frequently involves movement. Most adults easily clap or sway to a wide range of tempos, even without formal musical training. The link between movement and music emerges early--young infants move more rhythmically to music than speech, but do not reliably align their movements to the beat. Laboratory work…

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…

Purpose: Measuring the growth of young children's vocabulary is important for researchers seeking to understand language learning as well as for clinicians aiming to identify early deficits. The MacArthur-Bates Communicative Development Inventories (CDIs) are parent report instruments that offer a reliable and valid method for measuring early…

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…

While the World Federation of Occupational Therapy (WFOT) recommends that occupational therapists (OTs) competently respond to changing environments and new clinical practice and research demands (WFOT, 2012), there are many challenges for therapists to engage in professional development in countries where resources and specialized expertise are…

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…
