Previous research has found mixed results for a link between executive function and perspective-taking. One proposed reason for this is that perspective-taking during comprehension tasks may not be internally reliable. This dissertation presents two large individual differences experiments with multiple perspective-taking during comprehension and…

Over two-thirds of youth participate in a structured sport, making it a vital context in which transactional relations with cognitive development can occur. Yet, little is known about how these constructs inform one another across childhood. Most previous studies have focused on health benefits of sport participation, or on demographic and family…

Learning to read is an important milestone in children's development. Factors in the home environment is been linked to the behavioral and neural correlates of reading, but further work is needed to unpack the underlying mechanisms. The home literacy environment (HLE) plays a role in children's reading and language development, while parental…

Sleep is a vital human function, critical to health across the lifespan. However, college students report significant disturbances in sleep quality and sleep hygiene (ACHA, 2019; Moulin & Chung, 2016). The consequences of poor sleep include lower cognitive and executive functioning abilities (Honn et al., 2019; Whitney et al., 2015) and poorer…

School models have been slow to evolve, however, expectations of students in terms of schoolwork and homework have increased year over year. These increased demands require a high level of Executive Functioning (EF). However, a disconnect between the demands of schools and children's developing EF system have led to increased incidences of…

Executive function is deficient in individuals with ADHD. Playing a musical instrument has been shown to improve executive functions. This study examined if participants with ADHD perceived a connection between playing an instrument in a music ensemble and improved executive functioning, as well as improved ADHD presentations. The research design…

The problem was the decline in executive functioning skills of Grade 5 students in a consolidated independent school district in suburban Austin, Texas since the COVID-19 pandemic. The purpose of this qualitative critical instance case study was to better understand the perceptions of teachers regarding the impact of COVID-19 on the executive…

Anxiety in Children can develop into pervasive disorders in adulthood if not treated. Research shows dysfunctional Executive Function (EF) and anxiety are both shown to have a negative impact on math achievement in children and adolescents (Trezise & Reeve, 2018; Kalaycioglu, 2015; Owens, Stevenson, Hadwin & Norgate, 2012). Chung, Weyandt,…

The shift to online learning management systems such as Canvas seemed to assume students would become more independent and self-regulated, yet little research has been conducted in this area, especially with school-age students. This study examined the ways middle school students engaged with an online learning management system (LMS) and their…

This dissertation presents a series of case studies concerned with whether the signal in a given set of measurements that we take in the course of linguistic inquiry reflects grammatical competence or performance factors. We know that performance and competence do not always covary, yet it is not uncommon to assume that measurements that we take…

Executive function (EF) is a term used to describe the processes responsible for purposeful, goal-directed behavior and has been described as the "air traffic controller" or "CEO" of the brain. EFs are an important factor in overall quality of life, including school and job success. EFs are measured predominately through two…

Early childhood adversity, particularly poverty, can be a source of chronic stress that contributes to emotion dysregulation at the start of formal schooling. Children's reactivity to novel challenges in the classroom is associated with externalizing behavior and subsequent difficulties developing academic and social emotional skills (Blair &…

The purpose of this study was to examine the role of executive function (EF) skills (i.e., working memory, cognitive flexibility, and inhibition) in supporting the development of reading fluency in elementary school students with dyslexia. Participants were 47 students (i.e., second to sixth grade) attending a private school in the Mid-South…

Executive functioning abilities have been associated with important behaviors such as adaptive skills and cognitive abilities in children with and without disabilities. Executive functioning has primarily been measured as a strong predictor of later abilities in children with neurodevelopmental disabilities, such as attention-deficit/…

Technology is ubiquitous and takes many forms. Digital media consumption (e.g., television, video games, etc.) has increased significantly in its prevalence in our lives as well as in social acceptability. However, it has also been consistently implicated in poorer health outcomes. The extent to which cognitive functions are adversely affected by…
