The present study investigated the relationship between two major components of executive functioning (EF) and externalizing behavior problems (EBP) during the early elementary years. More specifically, Working Memory (WM) and Cognitive Flexibility (CF) measured in kindergarten through second grade were used to predict teacher ratings of EBP in…

Reading fluency involves a complex interaction of different cognitive skills and abilities that develop with instruction and practice and relies on the automaticity of many distinct reading skills (e.g., pacing, word recognition, expression, phonological awareness). Fluent reading frees cognitive resources, such as working memory, for more…

This dissertation study aimed to explore whether and how individual differences in verbal and visuospatial working memory capacity and executive functions influence elementary students' mathematics fact mastery and mathematics anxiety as they engage in learning using ReflexTM, a game-based, visuospatial rich adaptive learning platform for…

The purpose of this qualitative phenomenological study was to examine teachers' knowledge, attitudes, and beliefs about executive functions utilized in reading instruction of kindergarten through third-grade students. This research study used open-ended, semi-structured interview questions to gain a better understanding of what teachers know and…

The purpose of this study was to examine the role orthographic coding might play in distinguishing between membership in groups of language-based disability types. The sample consisted of 36 second and third-grade subjects who were administered the PAL-II Receptive Coding and Word Choice Accuracy subtest as a measure of orthographic coding…

Executive function skills have a direct link to reading comprehension (Carretti, Borella, Cornoldi, & De Beni, 2009). Specifically, cognitive flexibility and working memory have been shown as a significant contributor to reading comprehension (Cain, Oakhill, & Bryant, 2004; Cartwright, 2002). Understanding the link between cognitive…

This study investigated the differential contribution of auditory-verbal and visuospatial working memory (WM) on decoding skills in second- and fifth-grade children identified with poor decoding. Thirty-two second-grade students and 22 fifth-grade students completed measures that assessed simple and complex auditory-verbal and visuospatial memory,…

Current research suggests that certain cognitive functions predict the likelihood of intervention response for students who receive Tier 2 instruction through an RTI-framework. However, less is known about cognitive predictors of responder status at a theoretically more critical point of divergence within the RTI model: Tier 3. Moreover, no…

The purpose of this study was to evaluate the effect of rhythm and tonality on an academic memory task by comparing three different treatment conditions: a poem, a rhythmic chant (or rap), and a melodic rhythm (or song). A quasi-experimental experiment was designed and implemented, specifically a pretest-posttest-posttest control-group design.…

Calculation fluency weaknesses are a key characteristic of children with mathematics difficulties. The major aim of this dissertation was to uncover early predictors of calculation fluency weaknesses in second graders. Children's performance on number sense tasks in kindergarten along with general cognitive abilities, early literacy skills, and…
