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…

The current study addresses gaps in our understanding of the relationship between creative cognition, intelligence (IQ), and executive functioning (EF). Undergraduate students completed an IQ test, verbal and figural divergent thinking (DT) tests, and a self-assessment of EF, across four study sessions. Participant data (N = 199) were analyzed…

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…

Studies of switching between tasks and studies of error commission have both provided solid behavioral measures of executive control. Nonetheless, a gap remains between these strands of research. In three experiments we sought to reduce this gap by assessing the impact of task errors on N-2 repetition costs, an effect supposedly related to…

This study investigates the relationship among working memory (WM), mathematics, and language, with the aim of understanding: (1) whether the functions and capacities of WM components can predict achievement in language and mathematics; and (2) whether competence in the first language (L1) and achievement in mathematics can predict success in…

Objective: Children with ADHD often experience functional impairments across various aspects of daily life. This study addresses the dearth of longitudinal research on functional impairment trajectories from preschool to school age in children with symptoms of ADHD and comorbid disorders. Methods: We investigated the extent to which functional…

Background: While there is now considerable evidence in support of a relationship between executive function (EF) and academic success, these findings almost uniformly derive from Western and high-income countries. Yet, recent findings from low- to -middle-income countries have suggested that patterns of EF and academic skills differ in these…

Adolescents with attention-deficit/hyperactivity disorder (ADHD) are at heightened risk of experiencing academic difficulties due to organizational deficits. Impairment can be exacerbated through poor sleep hygiene and excessive daytime sleepiness, prevalent sleep challenges for adolescents with ADHD. Given established relationships among sleep,…

This study examined relations between intentional self-regulation (ISR) and executive functions (EFs) among 84 Icelandic youth in Grade 6 (mean age 11.7 years; 51% girls) and their contributions to healthy and problematic outcomes a year later. ISR was indicated by the Selection, Optimization and Compensation model (SOC) and Self-Regulated…

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…

Socioeconomic status (SES) and bilingualism have been shown to influence executive functioning during early childhood. Less is known, however, about how the two factors interact within an individual. By analyzing a nationally representative sample of approximately 18,200 children who were tracked from ages 5 to 7 across four waves, both higher SES…

Autistic traits and executive function (EF) were assessed in 413 typically developing children aged 6-9 years. The children were divided into the high- autistic-trait (HAT) and low-autistic-trait (LAT) groups based on their total autistic traits. Results suggested that there were gender differences in specific autistic traits in children with LAT.…

For young children, sleep is essential for healthy development. Inadequate sleep can affect emotional, behavioural, cognitive, and health outcomes. Low family income and resources can put children at risk for poor sleep quality, impairing their subsequent cognitive abilities. The current study examined low socioeconomic status (SES) as a factor…

Despite research demonstrating the importance of mathematics achievement to children's educational success and trajectories, many children enter kindergarten without the foundational mathematics skills needed to succeed (Garcia & Weiss, 2015). Children's executive function (EF) skills and their learning-related behaviors (Anthony & Ogg,…

The development of beginning decoding and encoding skills is influenced by linguistic skills as well as executive functions (EFs). These higher-level cognitive processes include working memory, inhibition, and cognitive flexibility, and individual differences in these EFs have been shown to contribute to early academic learning. The present study…
