This dissertation presents behavioral studies that target the early syntactic representations of "wh"-movement during infancy and early childhood. Previous studies show that by 20 months-old, infants represent "wh"-movement and use this knowledge to respond to "wh"-questions during language comprehension tasks…

Developmental research confirms the importance of early parental language input for building children's vocabulary and language skills (Hart & Risley, 1995). While reading with a caregiver is a common way for language input to occur, the approaches parents utilize often fail to capitalize on techniques for improving language and pre-literacy…

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…

The purpose of this study was to identify malleable practices in the homes of Spanish-speaking toddlers prior to school enrollment. This was achieved by examining daily activities and routines and the role older siblings played in these interactions to obtain a more comprehensive understanding of the home language and literacy environment and…

Outdoor play is a crucial in supporting child development, resiliency, social skills, creative thinking, adaptability, family growth, and family engagement. Unfortunately, children are spending less time outside because of technology, parent fears, and other factors. Parents who have a child with a disability have even more challenges when it…

The prevalence of late language emergence (LLE) in young children is high, comprising 10 to 20% of toddlers. Late language emergence refers to children who do not use at least 50 single words and 2-word phrases at the age of two. Current best practices for the under-three population with or at risk of having disabilities include the use of…

The problem addressed by this study was children's impeded oral language development when parents do not engage them in frequent conversational exchanges during the infant and toddler years. The purpose of the study was to explore parent behaviors and perceptions. Two questions guided the study: when do parents talk with their children? and how do…

Insufficient referral and participation in Part C Early Intervention (EI) services are common among children aged birth to 3 years, including those automatically eligible due to diagnosed medical conditions. States have established lists of diagnosed medical conditions to streamline eligibility determination for these children. However, there is…

Researchers have found young children's academic skills and life outcomes are correlated to teachers' postsecondary education. Despite this, 60% of infant/toddler-PK4 teachers who work in center-based settings in the District of Columbia do not have postsecondary education beyond the high school level. The purpose of this basic qualitative study…

In Taiwan, the high prevalence of emotional and behavioral problems in children has increased public awareness of young children's social-emotional development in recent years. Early identification of social-emotional delays for all young children, and subsequent early intervention (EI) with ongoing monitoring for children with special needs are…

Recent modeling work shows that patterns of shared perceptual features relate to the group-level order of acquisition of early-learned words (Peters & Borovsky, 2019). Here we present results for two eye-tracked word recognition studies showing patterns of shared perceptual features likewise influence processing of known and novel…

Infants and toddlers experience the world in interaction with others. Likewise, social interactions are important in learning about math--concepts of number ("one," "two," "three"), space ("on top," "upside-down," "round"), and magnitude ("more," "big,"…

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…

Rationale: Few communication interventions for Latino Spanish-speaking (LSS) families with young children with language impairments and autism have been experimentally tested. "EMT en Espanol" is a culturally and linguistically adapted language intervention that has been effectively implemented by LSS caregivers of children with…

There has been limited research on interventions with young children encompassing "interoceptive awareness," the awareness and perception of sensations from inside the body. The information in this phenomenological study examines how participants experienced a bidirectional, reflective, online intervention program on interoceptive…
