Research Findings: This study investigated the sequential mediating effects of parental material investment (MI) and time investment (TI) upon the correlation between family socioeconomic status (SES) and toddlers' development (TD). Data derived from a 2016 data set, including a sample of 1,316 toddlers based in 117 villages across 22 counties…

Childhood adversity can lead to cognitive deficits or enhancements, depending on many factors. Though progress has been made, two challenges prevent us from integrating and better understanding these patterns. First, studies commonly use and interpret raw performance differences, such as response times, which conflate different stages of cognitive…

The present study examined individual differences in the development of sustained attention across toddlerhood, as well as how these individual differences related to the development of language and sleep. Toddlers (N = 314; 54% male) were assessed at 30, 36, and 42 months using multiple measures of attention, a standardized language assessment,…

The purpose of this study is to examine the predictive effect of the variables of fathers' durations of working and spending time with their children on the aggression levels of 5-6-year-old children. The sample group of the study consisted of 90 children and their fathers. It was found that the fathers' daily and weekly working duration, the…

Grounded in the bioecological model of human development and attachment theory, this study examined whether the proportion of time children spend in activity settings in the kindergarten classroom moderated the relationship between teacher-child relationship quality and children's kindergarten academic and social-emotional outcomes. Participants…

The earliest experiences of children can ensure their future success, and parenting is noted to be an influential factor (Bronfenbrenner, 1979; Lamb et al., 2002). Many researchers theorized that parental involvement could encourage children to actively engage and improve their academic achievement in schools (Epstein, 2018). However, less…

Throughout the life span, we are capable of representing quantities in the absence of language, or nonsymbolically. Additionally, over the course of development, we learn many symbolic measurement systems for representing quantities such as time and number. Despite substantial evidence of a relation between the acquisition of symbolic and…

The role of early child care experiences on the development of the mother--child attachment relationship has been studied extensively. However, no prospective studies of early child care have addressed how these experiences might be reflected in the content of attachment representations during adolescence and beyond. The goal of this study was to…

The proliferation of electronic content and limited exposure of children to books in Jordan has made both parents and health-care providers more concerned about healthy child development. This research aimed to determine if pediatric primary prevention programs were helpful in reducing screen-time and improving reading habits of children in…

Each game within the Ignite by Hatch™ gaming environment belongs to an overall developmental domain and skills-based subdomain and is intended to meet the developmental needs of children at specific skill levels. These skill levels (Beginning, Emerging, Intermediate, Accomplishing, and Proficient+) form an intended developmental pathway. Children…

State-level policies in Ohio during the early months of the COVID-19 pandemic in the United States involved physical school closures and work-from-home requirements when possible. Presumably, these policies and resulting impacts on homes with children would alter parent time investments in their children with respect to home-learning activities.…

This dissertation consists of three independent chapters in applied microeconomics. In the first chapter, I study the causal effect impact of early life circumstances on adult psychological well-being using the property reform in China as a positive and policy driven change in economic resources in early life. Exploiting the staggered adoption of…

Research evidence suggests children experiencing adversity are at risk of language disparities in early childhood. This puts these children at risk of poor language outcomes, perpetuating disadvantage in later development and academic life. This study aimed to investigate associations between Early Childhood Education and Care (ECEC) attendance,…

Understanding the role of negative emotionality in the development of executive functioning (EF) and language skills can help identify developmental windows that may provide promising opportunities for intervention. In addition, because EF and language skills are, in part, genetically influenced, intergenerational transmission patterns are…

First-order and advanced theory of mind (ToM and AToM), and their structures and relations were investigated in 229 children aged 5-8 years. ToM was assessed using 6 tasks from the first-order ToM scale, while AToM was measured using an 18-item battery (higher-order false-belief understanding; strange stories; faux pas test; eyes test;…
