In this article, we present an analysis of the complexity of grammatical constraints and their impact on early language acquisition of inflectional morphemes in Malayalam. We use the natural speech production data of two monolingual children acquiring Malayalam between the ages 1;9-2;10 and 2;3-3;0 and three bilingual children acquiring…

The separation of young children from their families for most of their awake hours, and the specific segregation of children by discrete chronological age through classrooms and grade levels, is a relatively new phenomenon in the history of human society. Such settler colonial constructs continue to influence early learning design, policy and…

This study examines how individuals assess administrative burdens and how these views change over time within the context of the Special Supplemental Nutrition Assistance Program for Women, Infants, and Children (WIC), which provides food to pregnant and breastfeeding women and children under age five. Using interview data from the Baby's First…

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…

The present study investigated German-learning 6-month-old infants' preference for visual speech. Visual stimuli in the infants' native language (German) were contrasted with stimuli in a foreign language with similar rhythmical characteristics (English). In a visual preference task, infants were presented with 2 side-by-side silent video clips of…

The purpose of the current study was to examine effects of bilingual language input on infant word segmentation and on talker generalization. In the present study, monolingually and bilingually exposed infants were compared on their abilities to recognize familiarized words in speech and to maintain generalizable representations of familiarized…

In their first year, infants begin to learn the speech sounds of their language. This process is typically modeled as an unsupervised clustering problem in which phonetically similar speech-sound tokens are grouped into phonetic categories by infants using their domain-general inference abilities. We argue here that maternal speech is too…

Bilingual acquisition presents learning challenges beyond those found in monolingual environments, including the need to segment speech in two languages. Infants may use statistical cues, such as syllable-level transitional probabilities, to segment words from fluent speech. In the present study we assessed monolingual and bilingual 14-month-olds'…

This research investigates the development of constraints in word learning. Previous experiments have shown that as infants gain more knowledge of native language structure, they become more selective about the forms that they accept as labels. However, the developmental pattern exhibited depends greatly on the way that infants are introduced to…

Child's crying is the stimuli serving the development of a child-parent relationship through evoking child-oriented and parent-oriented parental reactions. Individual differences in parental reactions to crying have been partly explained by parental and child's temperament. We conducted two studies to verify the predicting effects of temperamental…

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…

Congenital heart disease (CHD), the result of structural changes to the heart present at birth, is the most common congenital birth condition. As survival rates for infants with complex CHD have increased in recent years, risk for neurodevelopmental challenges has also increased. Early referral to developmentally supportive care is recommended as…

Research indicates that the early years are a pivotal time for developing foundational mathematical knowledge, and that early experiences with mathematics have a lasting impact on later numeracy skills and academic achievement. However, the importance of early mathematical thinking and learning is often undervalued or overlooked in early childhood…
