How do children construct a concept of natural numbers? Past research addressing this question has mainly focused on understanding how children come to acquire the cardinality principle. However, at that point children already understand the first number words and have a rudimentary natural number concept in place. The question therefore remains;…

Developmental delays (DD) are missed early childhood developmental milestones in cognitive, motoric or linguistic domains. DD associated with behaviour problems may compound to impact parenting. This study investigated whether DD would moderate the relation between behaviour problems and parenting in families of toddlers. Data were drawn from an…

Social-emotional competence is important for children's lifelong positive developmental outcomes. The dimensionality and psychometric properties of a widely used social-emotional assessment, the Ages & Stages Questionnaires: Social-Emotional Second Edition (ASQ:SE-2), were investigated in this study using item response theory models. A…

Inconsistent findings regarding sex differences in cognition have been found in people with autism spectrum disorder (ASD). This study evaluated sex differences in cognitive-developmental functioning in a large clinical sample of young children diagnosed with ASD. The sample included children 18-68 months of age who received the Mullen Scales of…

There is scant empirical work on associations between current and past cannabis use in parents of young children. As recreational cannabis use is now legal in nearly half of states in the U.S., cannabis use is becoming more ubiquitous. In the current study, parents of toddler and pre-school age children were randomly assigned to participate in an…

We examined the pathway from grandparental childcare support at age 3 to child social and emotional outcomes at age 7 through maternal mental health and mother-child relationship at age 3 in a sample of n = 1495 biological mothers and their children from the UK's Millennium Cohort Study. Structural equation modelling showed that time spent in the…

In 2022-23, SRI Education conducted an evaluation of a pilot implementation of the Maine Early Childhood Consultation Partnership® (ECCP®) for Maine's Department of Health and Human Services, Office of Child and Family Services. Created and developed by Advanced Behavioral Health, Inc., ECCP® is an evidence-based, manualized model of infant and…

This special issue on early self- and co-regulation addresses a topic that is founded on a rich mix of theoretical perspectives, including self-determination theory, socio-cultural theory, attachment theory and artificial intelligence. Reflecting this diversity, the papers adopt a diverse range of approaches to cutting-edge questions regarding…

Background: The majority of children with cerebral palsy (CP) experience challenges in functional communication from a young age. A pivotal aspect of functional communication is language comprehension. A variety of classification systems and questionnaires are available to classify and describe functional communication skills in children with CP.…

Aim: There is a lack of evidence-based tools for measuring problem-solving in young children with motor delays. The purpose of this study was to evaluate the construct validity and responsiveness of the Assessment of Problem-Solving in Play. Methods: 125 young children (10.72, SD 2.62 months) with mild, moderate, and severe motor delays were…

Meta-analyses of head circumference in autistic individuals exist; however, simple meta-analytic approaches are limited. Consequently, we gathered head circumference raw data of autistic (N = 2381) and typically developing participants (N = 994) by re-analysing the data from previously published studies together. The present study found no mean…

Head Start programs engage parents to support children's growth from birth through age 5 through services that promote early learning and development, health, and family well-being. These programs specifically seek to assist families with low incomes and families facing a variety of other adversities. The Head Start REACH: Strengthening Outreach,…

The Autism Classification System of Functioning: Social Communication (ACSF) describes social communication functioning levels. First developed for preschoolers with ASD, this study tests an expanded age range (2-to-18 years). The ACFS rates the child's typical and best (i.e., capacity) performance. Qualitative methods tested parent and clinician…

This study examined an insufficiently studied predictor of functional language, social motivation, in a group of 87 young children with autism spectrum disorder. Participants (age 14-31 months at the start of the study) were assessed at four times over 24 months. We tested total and indirect associations between early social motivation and later…

Adults create and update predictions about what speakers will say next. This study asks whether prediction can drive language acquisition, by testing whether 3- to 4-year-old children (n = 45) adapt to recent information when learning novel words. The study used a syntactic context which can precede both nouns and verbs to manipulate children's…
