This study examines the effects of universal public pre-kindergarten for 3-year-olds (Pre-K3) on later public education outcomes, including enrollment, school mobility, special education status, and in-grade retention from kindergarten through second grade. While universal pre-kindergarten programs typically target 4-year-olds, interest in…

Early childhood providers care for infants and toddlers with developmental delays and special needs in their programs and classrooms. This study addressed the problem that there is insufficient professional development (PD) training for early childhood providers working with infants and toddlers with special needs in inclusive settings. The…

Longitudinal research on language abilities and social functioning in young children suggests that gains in one domain affect gains in the other. However, few studies have examined inter-relations of language and social functioning jointly among young children diagnosed with autism spectrum disorder (ASD). Pre-verbal toddlers with ASD are a group…

This study reports feasibility, fidelity and acceptability of a pilot of START; a 12-week parent-toddler, group-based, neurodiversity-affirming programme aiming to support executive function development in toddlers at elevated likelihood of autism or ADHD. After 4 days' training, community early years practitioner pairs delivered START to 13 UK…

Calls to bring more equity into science education research (McWayne and Melzi, 2023) are most notable for early childhood. We know very little about the teaching of science to infants and toddlers, yet this is where science education begins. To address the dearth in research, we undertook an in-depth intervention study in an Australian early…

The objective of this study was to evaluate the motor, cognitive and language development of babies living in two institutional contexts. Seventy babies participated in the study: 35 from prisons and 35 from shelters. Thirty-five mothers of hospitalized babies and 10 caregivers of hospitalized babies also participated in this study. The…

This paper reports on a young Korean boy's target-like and non-target-like uses of the Korean negation marker "ani" to express various types of negation in Korean, observed approximately between the ages of 2;2 and 2;5. Besides the target-like usage of "ani" as a sentential adverb for a 'no' response, he used "ani" in…

Development of professional competencies is a key outcome of undergraduate programs preparing practitioners to work with infants and toddlers. Competencies for working with young children were examined among 1300 undergraduate students at 12 universities. Students completed a series of online questionnaires indicating their knowledge, beliefs, and…

Previous research and theory indicate an importance of the quality of the early caregiving environment in the development of self-regulation. However, it is unclear how attachment security and maternal sensitivity, two related but distinct aspects of the early caregiving environment, may differentially predict self-regulation at school start and…

Identifying children with developmental disabilities is critical in providing early intervention services. This study aimed to evaluate the concurrent validity information of the 24-, 30-, and 36-month Indonesian Ages and Stages Questionnaires third edition (ASQ-3) with Bayley Scales of Infant and Toddler Development 3rd Edition (BSID-III) in…

Early attention bias to threat-related negative emotions may lead children to overestimate dangers in social situations. This study examined its emergence and how it might develop in tandem with a known predictor namely temperamental shyness for toddlers' fear of strangers in 168 Chinese toddlers. Measurable individual differences in such…

The current study took a person-centered approach to examine the heterogeneity of changes in children's emotions and persistence during a goal-blocking task and examined how different profiles of emotions and persistence related to children's self-regulation. Children's anger, sadness, and persistence were rated in a goal-blocking task in…

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…

While the association between shared book reading (SBR) and child language development is well documented, there has been less focus on how book characteristics may differentially elicit parents' language input and hence differentially relate to children's language skills during this activity. Moreover, despite the positive and unique role that…
