Most words spoken to infants are produced in larger units, such as clauses, phrases, and sentences. As such, language learners must recognize words amidst the words that surround them. However, the phonetic forms of words change based on surrounding context. Here, we investigate the effects of a common source of phonetic change--phonological…

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…

The topic of the three chapters of this dissertation is empowering caregivers of children with or at high likelihood for autism to implement interventions in home settings with high fidelity to promote their child's social communication development. Chapter 1 provides an overview of the previous studies focused on caregiver-implemented early…

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…

Joint engagement--the sharing of events during social interactions--is an important context for early learning. To date, sharing topics that are only heard has not been systematically documented. To describe the development of auditory joint engagement, 48 child-parent dyads were observed 5 times from 12 to 30 months during seminaturalistic play.…

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…

This current article is drawn from a qualitative study investigating the motivations and uses of digital devices of Singapore parents with their toddlers and preschoolers (age range: 1-5-year-old children). The article focuses on three prominent empirical findings. First, parent participants tend to try using a digital device with children to…

Children with neurogenetic syndromes (NGS) experience comorbid challenging behaviors and psychopathology. We examined challenging behaviors in 86 toddlers and preschoolers across three NGS [Angelman syndrome (AS), Prader--Willi syndrome (PWS), and Williams syndrome (WS)] and 43 low-risk controls (LRC), using the Child Behavior Checklist for Ages…

The timing of events (e.g., how long it takes a child to exhibit a particular behavior) is often of interest in developmental science. Multilevel survival analysis (MSA) is useful for examining behavioral timing in observational studies (i.e., video recordings) of children's behavior. We illustrate how MSA can be used to answer 2 types of research…

Universal screening and progress monitoring are evidence-based practices in early intervention/early childhood special education (EI/ECSE). Individual Growth and Development Indicators (IGDIs) for infants/toddlers are measures that programs can use for universal screening, progress monitoring, intervention decision-making, and accountability.…

Previous studies show that infants store functional morphemes for inferring syntactic categories of adjacent words, and they generally perform better with nouns than with verbs. In this study, we tested whether toddlers can exploit phrasal groupings for syntactic categorization in the face of noisy co-occurrence patterns. Using a visual fixation…

The present study aimed to investigate the communicative characteristics of children with cochlear implants (CIs) and their mothers in interaction, whether and how they differ from those of mother-child dyads with normal hearing, and whether mother and child influence each other over the first year after implantation. Eighteen Italian-speaking…

Extensive evidence and theory suggest that the development of motor skills during infancy and early childhood initiates a "developmental cascade" for cognitive abilities, such as reading and math. Motor skills are closely connected with the development of spatial cognition, an ability that supports deductive reasoning. Despite the…

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.…

Based on case studies in three states (CO, RI, and TX), this brief examines promising strategies to address the developmental and mental health needs of infants and toddlers involved in Child Welfare (CW). Due to family adversities, trauma, maltreatment, and separation from primary caregivers, these infants and toddlers are at substantial risk of…
