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…

Purpose: The goal of this study is to examine how shyness affects a child's performance on language assessments that vary in sociability. We hypothesized that accuracy on language tasks would be driven by shyness such that shyer children would perform better on nonsociable tasks compared to sociable tasks. Method: The procedures followed a…

Research Findings: Social constructivist theories have proposed that caregivers' perceptions of children as morally responsible agents are an important factor in children's moral development. However, there is substantial variance in caregivers' ascriptions of moral agency to young children. The present study examined caregiver social conformity…

Proactive interference (PI) occurs when previously learned memories compete with currently relevant information. Despite extensive literature investigating the effect in adults, little work has been done in young children. In three preregistered studies (N = 38, 35, 172; convenience samples from the Northeastern United States), first, we showed…

Young children's (n = 108) and adults' (n = 40) ability to compute ad-hoc quantity conversational implicatures was assessed using a new implicit task that relied on eye-tracking. The children were 2 and 5 years old. Looking times reveal that all participants interpreted simple references by relying on implicatures. However, 2-year-olds failed to…

Young learners are known to extend verb regularity further than it actually is. When it happens, this children's overregularization phenomenon can be a result of several reasons: a failed linguistic development due to confusion between rules and memory, a lack of feedback from adults, and problems with cognitive development. The present study…

Maternal substance use and unpredictable maternal sensory signals may affect child development, but no studies have examined them together. We explored the unpredictability, frequency and duration of maternal sensory signals in 52 Caucasian mother-child dyads, 27 with and 25 without maternal substance use. We also examined the association between…

Little is known about the modes of active commuting to and from school (ACS) in toddlers (2-3 years old). The aims of the present study are threefold: (a) to describe the modes of transport to and from early childhood education and care (ECEC) institutions in toddlers; (b) to analyze the role of different barriers and neighbourhood…

Background: In typically developing (TD) children, gesture emerges around 9 months of age, allowing children to communicate prior to speech. Due to the important role gesture plays in the early communication of autistic and TD children, various tasks have been used to assess gesture ability. However, few data exist on whether and how tasks…

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…

This study aimed to determine the effectiveness of a designed training program for nurses toward early detection of developmental disabilities among children aged 0-3 years. A group of 21 licensed nurses with professional experience ranging from 5-11 years participated in the study. The participants completed the measurements to evaluate their…

A best-evidence synthesis and meta-analysis were conducted to evaluate interventions designed to decrease noncompliance in early childhood settings. Studies were examined for quality, intervention components, and outcomes for young children (ages 2-8 years) across settings. Results indicated most designs were high-quality and produced desired…

Functional magnetic resonance imaging (fMRI) studies with adults provide evidence that functional brain networks, including the default mode network and frontoparietal network, underlie executive functioning (EF). However, given the challenges of using fMRI with infants and young children, little work has assessed the developmental trajectories of…

In their first three years, children begin to maintain topics and add new information in conversation. In turn, caregivers create opportunities for language learning. Compared to children with no family history of autism (typical likelihood, TL), the younger siblings of children with autism spectrum disorder (ASD) are at elevated likelihood (EL)…

Parents are in a powerful position to teach sexual topics to their children, promoting positive sex attitudes and lifelong sexual health. However, parents may lack sexual knowledge and confidence to address such topics. This study, grounded in social learning theory, tested the effects of an active learning intervention to increase parental…
