This dissertation consists of a theoretical review and two empirical studies investigating college students' academic effort beliefs (AEB) and their relationship to academic functioning. The overarching goal of this project was to (a) better understand how college students think about effort as it relates to their academic endeavors, (b) develop a…

In a sample of 216 high school students, we explored the relationship between hope and school belonging to executive functioning (EF). This examination was carried out to better understand how these, and potentially other psychosocial factors, relate to the neurocognitive decision-making process of adolescent students. This study had several…

We aimed to investigate the effects of phonological awareness -- PA, rapid automatised naming -- RAN, visuospatial and verbal working memory -- WM and executive functions -- EF on the reading and arithmetic skills of children with low- to medium-performance levels. Participants were 472 Brazilian children from 3rd to 5th grades. Quantile…

Objective: Examine how executive functioning (EF), healthcare management, and self-efficacy relate to college students' health-related quality of life (HRQOL). Participants: Undergraduates completed questionnaires at baseline (Time 1; n = 387) and 18-24 months later (Time 2; n = 102). Methods: Participants reported on their EF and healthcare…

Objective: The prevalence of stimulant medication misuse is rising in college students. Motivations to use stimulant medications differ from motivation to use other substances such as alcohol or cannabis. However, no previous research has examined the impact of achievement goal orientation on stimulant misuse in college students. Participants: 309…

Writing is a complex task that requires the activation and coordination of several processes. In addition to the research on the domain-specific factors that contribute to school achievement, there is an increasing interest on general variables, such as mindfulness. Here, we aimed to test the contribution of middle-grade students' trait…

Attention-Deficit/Hyperactivity Disorder (ADHD) is associated with academic failure in high school; however the underpinnings of these difficulties are insufficiently understood. This study examined deficits in self-regulated learning in a sample of high school students with ADHD (n=32) compared to demographically similar classmates without ADHD…

Researchers have found executive functioning (EF) to be important for reading and math performance but have paid less attention to their role in writing. Van Dijk and Kintsch (1983) identified three levels of writing: microstructure, macrostructure, and superstructure. The existing work on EF and writing has several limitations: researchers have…

Executive functions (EFs) show promise as important mediators of adolescent academic performance. However, the expense of measuring EFs accurately has restricted most field-based research on them to smaller, non-longitudinal studies of homogeneous populations with specific diagnoses. We therefore monitored the development of 259 diverse, at-risk…

A person-oriented approach examined the extent to which patterns of school readiness across social and cognitive domains in 944 typically-developing 54-month-old children forecast academic achievement, social-emotional development, risk taking, and executive functioning at age 15. Prior work identified six distinct profiles of school readiness at…

Objective: Emerging adulthood is an important phase in the transition to adulthood. Emerging adults experience minimal social control and incomplete development of executive functioning leaving this age-group at risk for misusing this newfound independence. Hence, it is important to understand pathways to support positive development (PD)…

In an attempt to better understand factors contributing to students' off-task electronic multitasking behavior in class, the research included two studies that developed a scale of students' off-task electronic multitasking predictors (the SOTEMP scale), and explored relationships between the scale and various classroom communication processes and…

Objective: This study tested the relationships among child executive function (EF), child-perceived parent fast food intake, and child self-reported subsequent consumption of high-calorie, low-nutrient (HCLN) food. Design: One year and 6-month longitudinal observation from a larger randomized controlled trial. Setting. Southern California…
