This quantitative correlational study investigates caregivers' attitudes toward sexual behavior and sex education for children with Down syndrome, drawing upon the theories of reasoned action and planned behavior. Data was collected from a convenience sample of 112 caregivers. The analysis revealed significant positive associations between…

Statistical learning (SL), the ability to detect and extract regularities from inputs, has been considered as an early-maturing and domain-general mechanism that is critical for typical language development. However, recent evidence in neurotypical adults and children have found that individuals can vary in their SL abilities across linguistic and…

Youth with disabilities are overrepresented in the bullying dynamic and experience poor mental health and school engagement outcomes associated with this involvement. However, limited existing research has looked at differences in bullying involvement based on disability category, and how youth with disabilities make decisions about bullying…

Speech exhibits quasi-rhythmic regularities at multiple timescales, which seem to be crucial to comprehension. Both children's ability to extract rhythm from complex stimuli and to produce rhythmic patterns are known to undergo changes from infancy to adulthood. However, it remains unclear what rhythm skills specifically related to speech look…

Writing is an essential skill that is critical for learning, communication and employment. Female advantages in writing test scores have been reported in several studies. The aims of this study were to systematically quantify sex differences in writing achievement as measured by individually administered achievement tests via multilevel…

Statement of the Problem: This study aimed to understand the impact of exposure to ACEs in childhood on college attainment in adulthood and if safe, stable, and nurturing relationships (SSNRs) in childhood mitigate the risks of exposure to trauma through a contextual lens by exploring results by race/ethnicity and gender. Research: Exposure to…

Adult humans are uniquely proficient in reasoning with abstract relations (relational reasoning) - a capacity which underpins much of human-unique cognition, including scientific analogies, artistic metaphors and many phrases in day-to-day language and thought. An important question for cognitive science, therefore, is exploring the nature of this…

In this dissertation, I explore how international migration and environmental pollution shape human capital accumulation and labor market outcomes.The first chapter examines how college enrollment and major choice decisions of young adults in migrant-sending countries are affected by the removal of international migration barriers. My…

Children in the United States live in a highly racialized society and, as a result, acquire an awareness of race at an early age, eventually developing an understanding of racism (Quintana, 2008). Understanding race and racism is especially relevant for Black children, given their marginalized status in the U.S. and the likelihood that they will…

Across five studies, this dissertation explores the thesis that children are sensitive to information about others' mental states and that this sensitivity scaffolds their learning in both the physical (Chapter 1) and social (Chapters 2 and 3) domain. Chapter 1 explores the interplay between the physical and mental world during visuospatial…

Despite changes in laws and access to education, individuals with disabilities continue to have fewer positive postsecondary outcomes than their non-disabled peers (Shogren et al., 2015). Negative secondary and postsecondary outcomes for individuals with disabilities include failure to graduate from high school, lack of postsecondary education,…

China, classified as a middle-income country by the World Bank, faces a scarcity of resources in providing autism interventions, despite a comparable autism prevalence in the Western world. Most autism interventions in China are imported from high-income countries, highlighting the need to examine whether the focus of the interventions from mixed…

The purpose of this study was to investigate how second-generation emergent bilingual Latina/o/x children are socialized to language and literacy practices in their rural community's school, home, and religious context. Gathering from theoretically grounded and research-based studies on language socialization, a qualitative study using…

Depression is a mental health diagnosis that affects many children and adolescents each year. While traditional methods of treatment include therapy and medication, physical activity could also be used as an additional tool to help combat depressive symptoms. A total of 51 articles were found to address the possible benefits of physical activity…

Researchers interested in understanding the perspectives of U.S. minoritized parents of children with special needs often recruit participants based only on their ethnicity (e.g., Zuckerman et al., 2015; Jegatheesan, 2011; Chiang, 2014). However, this strategy masks the additional, unique challenges of minoritized parents who immigrated to the…
