Children learn words in a social environment. In my dissertation, I examine how caregivers' social cues facilitate young children's word learning in settings that mirror their typical, dynamic learning environments. In Chapter 1, I overview prior work examining how social cues may support word learning, focusing on possible mechanisms underlying…

The home numeracy environment (HNE) is an essential factor to explain family engagement in relation to numeracy. Research in this field has mostly focused on English-speaking families and has not taken into consideration cultural differences that contextualize the home environment. Measuring HNE in more ethnically diverse samples might counter…

Background: Educational attainment is connected to many important life outcomes, and the previous research has already focused on identifying its genetic and environmental components. However, most of these studies used twin data only and did not incorporate information from other family members. Twin studies typically decompose the phenotypic…

The purpose of this study was to gain a clearer understanding of the relation between parental relationship qualities and overall emerging adulthood (EA) marijuana use processes. The present study drew from an ethnically and socioeconomially diverse sample of EAs (ages 19-22) and their parents (n = 470) from the Pacific Northwest region. This…

Previous research about children's digital play has predominantly focused on parental perspectives and parental mediation strategies. Although research on the effects of digital play on young children's development is plentiful, there is little evidence on young children's digital play addiction tendency. Herein, preschool children's digital play…

Background: Home mathematics environment (HME) research has focused on parent--child interactions surrounding numerical activities as measured by the frequency of engaging in such activities. However, HME survey questions have been developed from limited perspectives (e.g., "Early Childhood Research Quarterly," 27, 2012, 231;…

Today's youth will inherit the brunt of climate change. Science literacy plays a critical role in raising future adults who commit to climate change mitigation by reducing daily household energy use. The objective of this study was to examine the mediating role of climate change knowledge efficacy on the positive influence of science literacy on…

Children spend a large period of their lives close to their mothers gaining knowledge, learning many skills, and emulating them. Therefore, the objective of this research is to identify the relationship between mothers' educational levels and their children's academic performance. To achieve this objective, a quantitative research method…

Background: Reading interest plays an important role in predicting and regulating the literacy development of deaf children, but the family factors influencing their reading interest have not been previously explored. The purpose of this study was to explore the effects of parents' education and home literacy environment (HLE) on reading interest…

Consistent evidence points to the importance of the early childhood home environment for children's concurrent and subsequent development. Yet little is known about the long-term association between parental warmth in early childhood and children's social-emotional well-being in late childhood for children with and without disabilities. To explore…

The present study aimed to develop and validate a questionnaire assessing parents' beliefs about, and attitudes toward, supporting young children's English as a second/foreign language development -- Parent English Language Belief and Attitude Questionnaire (PELBA-Q). The PELBA-Q was piloted with 173 parents of kindergarten-aged children and…

Unintentional injury represents a significant health threat to children, and infancy marks a particularly vulnerable stage. This multi-method study (questionnaire, diary) measured parents' (N = 143) use of three popular home-safety practices (teaching about safety, environment modification to reduce access to hazards, supervision) and child injury…

Real-time attention coordination in parent-toddler dyads is often studied in tightly controlled laboratory settings. These studies have demonstrated the importance of joint attention in scaffolding the development of attention and the types of dyadic behaviors that support early language learning. Little is known about how often these behaviors…

Children's daily contexts shape their experiences. In this study, we assessed whether variations in infant placement (e.g., held, bouncy seat) are associated with infants' exposure to adult speech. Using repeated survey sampling of mothers and continuous audio recordings, we tested whether the use of independence-supporting placements was…

With the rapid progress of technological development, self-efficacy in reference to digital devices (i.e., information and computer technology [ICT] self-efficacy) is an important driver that helps students to deal with technological problems and support their lifelong learning processes. Schools, peers, and home learning environments are…
