Biculturalism, Bilingualism, & Executive Function Among U.S. Latinos: Implications For Cognitive Reserve, Leticia G. Vallejo

Dissertations (1934 -)

The current study was an exploratory investigation of the cultural constructs of biculturalism and bilingualism as predictors of executive function among a community-based sample of 25 older adult Latinos living in the U.S. The potential moderating effects of education and bicultural identity integration were also examined. Using regression analyses, biculturalism and bilingualism were examined independently as predictors of performance on three separate tasks of executive function: trail making tests, a phonemic fluency task, and a clock drawing task. Bilingualism was not found to predict performance on any of the executive functioning tasks. In the overall sample, biculturalism also was not …

Executive Functions And Word Reading Fluency: A Brief Intervention With Economically Disadvantaged Secondary Students, Vanessa Kim

PCOM Psychology Dissertations

This study evaluated the use of a brief intervention that was designed to assist economically disadvantaged secondary students increase their capacity for attention to orthography and increase their ability to shift between rapid sight word recognition and decoding of unknown words in order to improve their word reading accuracy and fluency. The participants (N = 14) were eighth and ninth grade students enrolled in an urban public high school and receiving special education services. The study used analysis of variance for repeated measures and paired measures t-tests to analyze pre- and post-test data. The results indicated significant findings (p < 0.5) in the students’ improvements in their sight word reading fluency and their ability to inhibit impulses and shift cognitive sets with accuracy and speed following the 8-week reading intervention. The findings suggest that exposure to repeated word fluency drills that target attention to orthography and shifting from sight word recognition to decoding may have influenced the students’ self-monitoring skills and offer further support regarding the hypothesized role of executive functions in the act of reading.

The Role And Implications Of Executive Functions On Learning And Performing Math In High School Algebra I Students, Heather Lynn Rickmers Tacovsky

PCOM Psychology Dissertations

Current research is largely lacking in the areas of math, math learning deficits, and math-specific interventions. Even less available is research and interventions specific to high school learners. Some research addresses these areas with a specific focus on executive functions and how they may relate to student learning and performance. The present study sought to determine the relationship between three specific executive functions, Shift, Inhibit, and Working Memory, on learning and performance in math. Other executive functions, as measured by BRIEF rating scales and including Planning and Organization, Initiate, and Monitor, were also reviewed. Results of the present study found …

Examining The Role Of Executive Functions In Focal Processing Of Event-Based Prospective Memory, Tatsuya T. Shigeta

Theses and Dissertations

Prospective Memory (PM) refers to remembering an intention to be acted upon in the future. Such a memory may be triggered by an event (i.e., Event-based PM) where a specific cue reminds one of the previously encoded intention. PM can be assessed in a lab-setting by having subjects learn a baseline task, subsequently receiving a PM instruction, completing a distractor task, and then going through a test phase where the PM task (i.e., responding to PM cues) is embedded within the ongoing task. The multiprocess view (McDaniel & Einstein, 2000) posits that PM can be retrieved primarily using two different …

Chronotype Preference, Partial Sleep Deprivation, And Executive Functions Performance Throughout The Wake-Cycle, Devin Layne Merritt

Doctoral Dissertations

Sleep is vital to survival and well-being. Adequate sleep, which is conceptualized in terms of quantity and quality, is positively related to a number of cognitive functions. In terms of length, it has been recommended that individuals in late adolescence and adulthood should receive no less than eight hours of sleep. Negative effects on higher-order mental processes have been found in states of sleep deprivation. Individuals who experience total sleep deprivation show decrements in performance on tasks of executive function (i.e. sustained attention, planning, and decision making). However, the effects of partial sleep deprivation on executive functions has not been …

An Analysis Of Teacher’S Judgements Of Student’S Executive Functions And Percieved Academic Competency Across Age Groups, Evan Skolnik

PCOM Psychology Dissertations

In the school setting, well-developed executive functions are associated with the metacognitive skills important for learning and are positively correlated with measures of student achievement across children and adolescents; however, development of executive skills has been shown to be inconsistent with chronological age among children. The current study examined if teachers’ ratings of students’ executive functions differ significantly among groups of students whose academic competence is judged to be above average, average, and below average and if these ratings differ significantly by age. Further, the study sought to determine if the relationship between teachers’ ratings of executive functions and teachers’ …

Executive Function Predictors Of Children's Talk, Jacqlyne D. Weber

Undergraduate Honors Theses

Relatively few studies have investigated the relationship between executive functioning (EF) and language development, and even fewer have researched hot and cool EF as a predictor language development. This study is an investigation into the relationship between EF and language development in preschool aged children. More specifically, the ability for hot or cool EF to predict language, this will be the focus of the study. It was found that hot EF was a better predictor of language development in preschool aged children.

Exploration Of The Wechsler Memory Scale Fourth Edition And Measures Of Executive Function Combined Components Model, Isaac Tourgeman

Theses and Dissertations

While memory is the faculty that affords us learning, adaptation and development, it is our executive function that oversees, manages and organizes these abilities. Still, there is limited research on the interaction between memory and executive function. The present study investigated this relationship through Principal Components Analysis. Performances on accepted measures of memory and executive function were evaluated in an adult clinical sample. Components were retained using three criteria: a predetermined four-component structure, eigenvalues exceeding a value of one, and parallel analysis. Results demonstrated that a four-component model most accurately represented the data. Analyses also revealed that measures of immediate …

The Trends Study : Examining The Relationship Between Executive Function, Temperament, Quality Of Life, And Bmi In Young Adults, Renata Vaysman

Legacy Theses & Dissertations (2009 - 2024)

This study examined the relationship between executive function (EF) abilities, quality of life (QoL),temperamental qualities (EC: effortful control and NA: negative affect), and Body Mass Index (BMI) in a sample of young adults. Previous studies indicated that deficits in various domains of EF are associated with higher BMI and lower QoL. This study did not find statistically significant differences in EF skills based on BMI. Additionally, in this sample, there were no significant relationships between BMI and QoL. However, interesting relationships emerged between EF skills and NA, as well as EF skills and physical QoL. Furthermore, there is some evidence …

Impairment And Executive Functioning Associated With Symptoms Of Sluggish Cognitive Tempo, Adhd, Anxiety, And Depression, Whitney Lee Muhlenkamp Wood

Psychology - Theses

This study examined the relationships among Sluggish Cognitive Tempo (SCT), ADHD, anxiety, and depression symptom sets in a college sample, and the extent to which these symptom sets predicted executive functioning and functional impairment. Also, this study investigated (a) the extent to which functional impairment and executive functioning (EF) problems were uniquely accounted for by SCT symptoms when controlling for ADHD, anxiety, and depression symptoms, and (b) which high symptom group accounted for the greatest amount of impairment. College students (N = 458) completed a demographic questionnaire and self-report scales of ADHD, SCT symptoms, anxiety, and depression symptoms, as well …

Biases In Children's Cognitive Styles: Investigating Local, Global, And Rule-Based Processing In Autism Spectrum Disorders And Typical Development, Sandra Beatriz Vanegas

Dissertations

Autism Spectrum Disorders (ASD) is classified as a pervasive developmental disorder that presents a triad of impairments across communication, social behavior, and restricted interests (American Psychiatric Association, 2000). To date, many attempts have been made to explain the cognitive profiles of children and adults with ASD. Three prominent theories, Weak Central Coherence (Frith, 1989), Systemizing (Baron-Cohen, 2002), and Executive Dysfunction Theory (Pennington & Ozonoff, 1996), may together provide a plausible explanation for the cognitive biases of individuals with ASD.

Weak Central Coherence (WCC) Theory proposes that individuals with ASD have difficulty learning new information due to a fixation towards local …

The Multi-Scale Dynamics Of Executive Function, Jason Anastas

Master's Theses

Cognitive control is a central issue in developmental psychology. Traditional theories of psychology solve this problem by positing a top-down central executive, which coordinates cognitive resources in pursuit of goals. We propose an alternative explanation: cognitive control arises from physical interactions across many different timescales within the system. College and preschool aged participants were asked to complete a simple executive function task, card sorting. We found that multi-scale physical interactions differed depending on experimental constraints, and that executive function in these cases was driven primarily by flexibility in multi-scale interactions, rather than the dominance of one scale. This suggests that, …

Executive Functions In The Schools: What Do Teachers Know About Executive Functions And How They Impact Student Progress?, Larissa Morgan-Borkowsky

PCOM Psychology Dissertations

The current study surveyed middle school teachers on their knowledge, attitudes, beliefs, and expectations regarding executive functions in relation to students’ academic success. The results of this study indicated that teachers perceived themselves as knowledgeable of executive functions. A disconnect was found between teacher responses to an open-ended question regarding abilities and skills required for academic success and their endorsements of specific questions regarding executive functions. Motivation, problem-solving, and basic academic skills were indicated as being most important for success, but two of these are considered capacities students possess intrinsically. When asked about specific executive functions however, they rated them …

Self-Regulation: The Link Between Academic Motivation And Executive Function In Urban Youth, Sara Ferry Walker

PCOM Psychology Dissertations

The present study investigated the relationship between academic motivation and executive function skills through teacher reports of prototypical students, perceived to lack motivation. Second, the study examined the effect of grade level (i.e., elementary, middle, high) on both teacher-perceived academic motivation and executive function skills for these prototypical students. It was hypothesized that there were significant relationships between executive function processes and academic motivation. It was also hypothesized that due to the decline in academic engagement during adolescence, middle school and high school teachers would perceive higher levels of executive dysfunction and deficits in academic motivation than would elementary teachers. …

Program Evaluation Of An Executive Functions Intervention At A Middle School Setting, Minu S. Poulose

PCOM Psychology Dissertations

Executive functions play an important role in children’s cognitive, academic and social functioning. The present study investigated the changes in executive functions in students who were enrolled in an academic support period everyday for forty-five minutes. Participants included twenty-six eighth-grade students eligible for Special Education and Related Services in a suburban middle school in New Jersey. The study used archival data consisting of items from the 44-item Executive Functions (EF) Rating Scale, a questionnaire that was completed by middle school special education teachers. To examine differences within groups, repeated measures analysis of variance (ANOVA) were conducted to examine teacher ratings …

The Implications Of Executive Function And Prototypical Student Performance In Middle School, Sabrina Anne Hartman

PCOM Psychology Dissertations

Over the course of the past 25 years, “executive functions” have been investigated more and more frequently in relation to cognitive functioning across the lifespan. Within that time frame, researchers have examined various changes that are specific to the adolescent brain. The research has begun to elucidate the relationship between executive functioning and the developmental period of adolescence. Previous studies have examined the utility of using specific rating scales as a means to assess executive functioning across the lifespan, with most of these utilizing scale level analyses. Given the lack of specificity regarding what elements exactly comprise “executive functioning,” the …

Profiling Executive Dysfunction In Adolescents With Autism, Nicole R. Rogers

PCOM Psychology Dissertations

Executive Functions (EF) have been assigned a causative role in a number of disorders, including schizophrenia, Tourette syndrome, autism, obsessive compulsive disorder, violent and criminal behavior, and nearly all learning disabilities. While the term executive functions in the professional literature easily yields more than 150 references, empirical research in which executive functions are studied and linked with specific disorders, such as autism, continues to help answer long-held questions about the disorder and adds to the literature base in order to better understand and treat the disorder. The purpose of this study was to review archival data collected using the Behavior …

An Exploration Of The Relationship Between Personality Traits And Cognitive Functioning In Neuropschological Outpatients In Community Based Treatment, Stacey Rivenburg

PCOM Psychology Dissertations

This study examined whether behavioral disturbances in obsessive compulsive personality disorder and borderline personality disorder were related to executive functioning. An archival database was used; this consisted of 104 subjects who had been given the Millon Clinical Multiaxial Inventory-III (MCMI-III) and the Wisconsin Card Sorting Test (WCST) at a local neuropsychology practice. Comparisons in executive functioning abilities were made between groups of subjects identified as reporting obsessive compulsive personality disorder traits or borderline personality disorder traits, and also between groups of subjects identified as reporting both obsessive compulsive personality traits and borderline personality traits. Findings concluded that a relationship does …

The Relevance Of Executive Functions In Academic Production In Middle School, Norina Bobik

PCOM Psychology Dissertations

The present study investigated the role that executive function plays on academic production in middle school from a prototype perspective. It was hypothesized that middle school teachers' prototypical ratings of the executive function capacities of middle school students who are academically successful would differ significantly from these same middle school teachers' prototypical ratings of the executive function capacities of middle school students who are academically unsuccessful. The study used archival data consisting of items from the Behavior Rating Inventory of Executive Function (BRIEF), a questionnaire that was completed by middle school teachers during a professional in-service workshop at four large …
