Cognitive Functioning In Well-Controlled Asthma, Erin Walsh Jan 2024

Cognitive Functioning In Well-Controlled Asthma, Erin Walsh

West Chester University Doctoral Projects

Asthma is a common lung disease that impacts lung functioning through inflammatory based mechanisms. Past research suggests that decreased blood oxygenation due to asthma attacks may impair cognitive capabilities (Irani et al., 2017). Moreover, the observed differences in cognition between those with and without asthma may be associated with disease severity or asthma control respectively in asthma populations. The current study explored differences in cognitive functioning between college students with and without self-reported asthma. Sociodemographic data, self-reported asthma severity, and measures of asthma control were collected. The current study did not find significant differences in measures of cognitive efficiency between …


Does The Apoe-Ε4 Allele Differentially Influence Cognition: A Longitudinal Investigation In Healthy Older Adults At Risk For Alzheimer’S Disease, Aditya Kulkarni Sep 2023

Does The Apoe-Ε4 Allele Differentially Influence Cognition: A Longitudinal Investigation In Healthy Older Adults At Risk For Alzheimer’S Disease, Aditya Kulkarni

Dissertations, Theses, and Capstone Projects

Background: The apolipoprotein E (APOE) ε4 allele is the strongest susceptibility factor for sporadic, late-onset, Alzheimer’s disease (AD). However, not all persons who carry the ε4 allele show significant cognitive decline, and thus do not progress to dementia. The impact of the ε4 allele on memory decline has been documented primarily in populations already demonstrating cognitive impairment (i.e., those with mild cognitive impairment or dementia), with fewer investigations completed in baseline healthy older adults. Investigations of the ε4 allele and its influence on non-memory domains are also sparse in the literature. Furthermore, these cognitive investigations are typically cross-sectional and …


Pinpointing The Cognitive Structure Of The Cpt-3: A Case For Distribution Appropriate Statistical Methods, Chandler J. Zolliecoffer Aug 2023

Pinpointing The Cognitive Structure Of The Cpt-3: A Case For Distribution Appropriate Statistical Methods, Chandler J. Zolliecoffer

Theses and Dissertations

The present study used the CPT-3 as a model to illustrate the complementary use of distribution-appropriate statistical methods to analyze non-normally distributed empirical datasets. Study results reaffirmed that while group-level analysis (e.g., via traditional parametric group-level analysis or distribution-appropriate group-level analysis procedures) offers insights into performance of the group in aggregate, it is oftentimes inappropriate to presume that patterns reflected by the group are, necessarily, applicable to a smaller subset of respondents. Thus, understanding how subgroups within the population navigate and approach a given task can have direct implications for more personalized/individualized assessment and treatment, especially in clinical and research …


Measurement Invariance Of Impact In Bilingual And Monolingual High School Athletes, Hana Cecilia Kuwabara Aug 2023

Measurement Invariance Of Impact In Bilingual And Monolingual High School Athletes, Hana Cecilia Kuwabara

UNLV Theses, Dissertations, Professional Papers, and Capstones

Given the reported negative consequences of sport related concussion (SRC), establishing the validity of concussion management tools is essential if they are used to determine the severity of concussion, track recovery or decline, implement effective interventions, and assist in return-to-play decision making. Previous research has found cognitive and symptoms differences on ImPACT, the most widely used SRC assessment measure, between monolingual and bilingual student athletes. Before further investigation of these differences can occur, measurement invariance of ImPACT must be established to ensure that differences are not attributable to measurement error. The current study has two aims: 1) to replicate a …

The Impact Of Cannabis Use On Neuropsychological And Neural Biomarkers Of Treatment Response In Schizophrenia Spectrum Disorders, Melanie B. Thies Sep 2022

The Impact Of Cannabis Use On Neuropsychological And Neural Biomarkers Of Treatment Response In Schizophrenia Spectrum Disorders, Melanie B. Thies

Dissertations, Theses, and Capstone Projects

Cannabis use among patients with schizophrenia-spectrum disorders (SSD) is at significantly greater levels than in healthy populations but the impact of cannabis on neural mechanisms of clinical improvement is poorly understood. Cognitive functioning and neural connectivity are disrupted as a result of both SSD and cannabis use, and research indicates that neuropsychological capacity and connectivity of the striatum, a region involved in salience and reward processing, may be integral to effective antipsychotic drug (AP) treatment response. Despite this overlap, no previous research has investigated the effect of cannabis on the brain functions implicated in AP treatment response. The present study …


Serial Position Effect Profiles And Their Neuroanatomical Correlates: Predictors Of Conversion To Alzheimer's Disease, Isabelle K. Avildsen Sep 2022

Serial Position Effect Profiles And Their Neuroanatomical Correlates: Predictors Of Conversion To Alzheimer's Disease, Isabelle K. Avildsen

Dissertations, Theses, and Capstone Projects

The current study was designed to determine whether targeted, premorbid, neuropsychological measures of the serial position effect (SPE) can detect and explain risk for later development of Alzheimer’s disease (AD). The study tested the utility of SPE measures in healthy controls (HC) and individuals already diagnosed with mild cognitive impairment (MCI) or AD. Aim 1 was to determine whether these sensitive, valid neuropsychological measures can explain disease risk. SPE of list-learning are highly sensitive cognitive markers that capture important elements of both linguistic and amnestic mechanisms of encoding, learning, and retrieval. Using the Rey Auditory Verbal Learning Test (RAVLT), we …


Providing Effective Assessment Feedback To Patients: Lessons Learned From Feedback After A Severe Injury, Kelsie Mcquinn May 2022

Providing Effective Assessment Feedback To Patients: Lessons Learned From Feedback After A Severe Injury, Kelsie Mcquinn

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

This paper seeks to articulate lessons learned from feedback received after a severe injury in order to help guide neuropsychologists provide effective feedback to patients. Given that there is no agreed upon conceptual framework for providing neuropsychological assessment feedback, parallels are drawn from what works in clinical psychology – the working alliance. I use personal examples to highlight how the working alliance, as well as other psychological principles, can help inform neuropsychologists provide the most effective feedback to patients.


Changes In Cognitive Networks As A Result Of Sport-Related Concussion, Grace J. Goodwin May 2022

Changes In Cognitive Networks As A Result Of Sport-Related Concussion, Grace J. Goodwin

UNLV Theses, Dissertations, Professional Papers, and Capstones

Given the high prevalence of concussion in sports, assessment of cognition has become a standard part of athletics, and results are used to inform return to play decisions. Neurocognitive measures (e.g., ImPACT) generate cognitive composite scores from individual subtests, and these scores are compared at baseline and post-concussion. Declines in scores provide evidence for concussive injury, and athletes undergo repeated assessments until their scores and symptoms improve. Recent research suggests that changes in the associations between test scores may provide important information about cognitive recovery. A network framework may help identify post-concussive cognitive changes that may not be apparent when …


Association Of Early Life Stressors With Deficits In Child And Adolescent Cognitive Functioning, Emily M. Deming Jan 2022

Association Of Early Life Stressors With Deficits In Child And Adolescent Cognitive Functioning, Emily M. Deming

Graduate Theses, Dissertations, and Problem Reports

The purpose of this study was to determine whether the ACEs questionnaire could be a viable screener tool for identifying children in need of neuropsychological testing. This study consisted of a sample of child participants aged 8-17 years (N=53) who were divided into a no ACEs group or the ACEs group (1 or more ACEs) depending on parental responses to the ACEs questionnaire. Participants completed a series of virtual neuropsychological tests that assessed overall neurocognitive functioning, memory, and attention. No significant differences between the no ACEs group and the ACEs group in performance of the overall Neurocognitive Index, …


Cancer Related Cognitive Impairment In Breast Cancer Patients: Guidelines For Neuropsychological Evaluation And Management, Ali Al-Humadi Jan 2022

Cancer Related Cognitive Impairment In Breast Cancer Patients: Guidelines For Neuropsychological Evaluation And Management, Ali Al-Humadi

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Current literature indicates there is still some debate regarding the scope and severity of cancer treatment related cognitive impairment (CRCI), with a wide variety of complex factors contributing to cognitive decline and discrepancies between objective findings and patient self-report. This paper aims to provide guidelines for neuropsychological evaluation, management, and rehabilitation of CRCI in breast cancer patients based on current research. This paper also aims to discuss current research on proposed mechanisms of action for CRCI, the cognitive domains affected in CRCI, and significant bio-psycho-social risk factors impacting CRCI.


Cerebellum-Seeded Functional Connectivity Changes In Trait-Anxious Individuals Undergoing Attention Bias Modification Training, Katherine Elwell Jul 2021

Cerebellum-Seeded Functional Connectivity Changes In Trait-Anxious Individuals Undergoing Attention Bias Modification Training, Katherine Elwell

All NMU Master's Theses

Anxiety and anxiety related disorders are increasing at a drastic rate in the past decade, with the NIMH reporting that 31.1% of U.S. adults will experience an anxiety disorder at some point in their lives. Anxiety is commonly characterized by increased attention bias to threat. Attention Bias Modification (ABM) is a new treatment used to reduce individual’s attention bias towards threat. The extent to which ABM leads to underlying neural changes is still unknown. The cerebellum is a neglected brain structure, with new research provides evidence that cerebellum’s functional connectivity and shared networks with threat processing regions has a direct …


Executive Functioning And Purpose In Life Among Emerging Adults In College, Alexis Kaylyn Liberto Jan 2021

Executive Functioning And Purpose In Life Among Emerging Adults In College, Alexis Kaylyn Liberto

Electronic Theses and Dissertations

Background: Executive functioning (EF) is a complex neurocognitive concept that grew from the field of neuropsychology and has been explored through various avenues. The most accepted theoretical organization of EF includes a three-factor model that is comprised of inhibition, updating, and shifting. The three-factor conceptualization can be measured through various objective EF neuropsychological assessments and self-reported levels of EF abilities. Goal-planning and organizing cognitive processes are another important facet of EF, as they involve self-regulation abilities. Individuals able to “regulate” themselves behaviorally and move towards goals tend to be more successful and move towards their purpose in life. A facet …


Psychological Effects Of Testosterone Replacement Therapy For Secondary Hypogonadism, Minerva Spurlock Jan 2021

Psychological Effects Of Testosterone Replacement Therapy For Secondary Hypogonadism, Minerva Spurlock

Walden Dissertations and Doctoral Studies

Hypogonadism negatively impacts various psychological aspects of a male’s life. Males under the age of 50 who experience symptoms of depression or a decreased sense of well-being may not be aware that secondary hypogonadism might be the underlying cause. A gap exists in the literature regarding the psychological effects of testosterone replacement therapy used to treat hypogonadism. The current research project was framed by Engel’s biopsychosocial theory, which encompasses the biological, psychological, and social aspects of a client’s life. The research objective was to determine the relationship between testosterone replacement therapy and the psychological effects of depression and quality of …


The Relation Between Hyperlipidemia, Hypertension, And Downstream Cognitive And Neuroanatomical Function, Victor James Wasserman Dec 2020

The Relation Between Hyperlipidemia, Hypertension, And Downstream Cognitive And Neuroanatomical Function, Victor James Wasserman

Theses and Dissertations

Objective: Cardiovascular risks (CVR) such as hypertension and hyperlipidemia play a critical role in the emergence of dementia syndromes. Medication to treat CVR may not obviate downstream risk for cognitive change.

Methods: To examine the relation between history of treatment with medications to treat CVR and cognitive outcomes, participants were seen at time points ~7 years apart, completed neuropsychological evaluations, assessed for history of treatment with medication associated with hypertension and hyperlipidemia as indicators of CVR, and classified into 3 groups: Not Treated, Inconsistently Treated, and Consistently Treated. Regression models associating neuropsychological outcome measures of cognition and CVR were explored …


The Association Of Aerobic Fitness With Resting State Functional Connectivity And Verbal Learning And Memory In Healthy Young Adults, Kyle Joseph Jennette Aug 2020

The Association Of Aerobic Fitness With Resting State Functional Connectivity And Verbal Learning And Memory In Healthy Young Adults, Kyle Joseph Jennette

Theses and Dissertations

The beneficial effects of exercise and cardiopulmonary fitness on general health, quality of life, and reduction of mortality are well known in older adults. There is evidence to support the positive effects of exercise and aerobic fitness on psychiatric and neurocognitive function in children, adults, and older adults. Indeed, many studies have explored the positive effects of aerobic fitness on slowing cognitive decline associated with normal and pathological aging. However, comparatively fewer empirical studies in the literature exist to support and understand the effects of aerobic fitness on the developing brain, particularly during adolescence and young adulthood, especially as it …


Examining Patterns Of Executive Functioning Across Dimensions Of Psychopathology, Scott Roye Jul 2020

Examining Patterns Of Executive Functioning Across Dimensions Of Psychopathology, Scott Roye

LSU Doctoral Dissertations

Executive functioning is a multifaceted collection of higher-order cognitive processes used to perform goal-oriented tasks. Although this construct is heavily researched, a major issue regarding the current literature stems from the influence of task impurity, which interferes with how executive functioning performance is interpreted. Additionally, while executive functioning has been previously explored in clinical populations, less work has evaluated this topic measuring dimensional psychopathology. The present study sought to examine the role of executive functioning, as it relates to dimensional psychopathology. Data was analyzed from a total of 731 individuals between the age of 18-59 years who took part in …


The Relationship Between Neuropsychological Functioning, Biomarker Av-1451, And Subjective Memory Impairment In A Cognitively Normal Sample, Amberrose Reale-Caldwell Jun 2020

The Relationship Between Neuropsychological Functioning, Biomarker Av-1451, And Subjective Memory Impairment In A Cognitively Normal Sample, Amberrose Reale-Caldwell

Dissertations

Mild cognitive impairment (MCI) is often a prodromal stage for Alzheimer’s disease (AD) development, with those diagnosed with MCI at increased risk for developing AD. The present study aimed to provide data to support a prodromal stage of MCI via analysis utilizing the neuropsychological domain of memory, subjective memory impairment (SMI), and the PET tau biomarker, AV-1451. It was hypothesized that individuals with SMI would differ significantly from participants without SMI (nSMI) on measures of memory and level of tau binding in the entorhinal cortices and the hippocampi. It was further hypothesized that differences in memory would be mediated by …


Off-Topic Verbosity And Sustained Attention Among Young Adult And Older Adult Age Cohorts, Jessica H. Helphrey May 2020

Off-Topic Verbosity And Sustained Attention Among Young Adult And Older Adult Age Cohorts, Jessica H. Helphrey

Psychology and Counseling Theses

Off-topic verbosity (OTV) is tangential discourse with excessive and irrelevant information. Older adults have been historically labeled as having high OTV, and research has suggested that high OTV in older adults may be linked with cognitive decline. While past studies have utilized brief cognitive measures to further expound upon the links between cognition and OTV, studies have lacked consistency and lengthy measures. This study sought to elucidate the relationship between OTV and cognition in both older adult and young adult age cohorts utilizing a sustained attention measure. Young adults (n = 61; age range: 18-28, M = 20.57, SD = …


The Role Of Awareness In Traumatic Brain Injuries: Interviews With Experts, Dominique Chao Jan 2020

The Role Of Awareness In Traumatic Brain Injuries: Interviews With Experts, Dominique Chao

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Approximately 2.8 million US citizens sustain a traumatic brain injury (TBI) annually, with more than 275,000 requiring inpatient rehabilitation (Taylor, Bell & Breiding, 2013). As rehabilitation techniques are refined and adapted to increase the speed of recovery and functional independence following TBIs, there is an ongoing need for better prognostic assessment tools. Research has shown that a lack of self-awareness following TBI is associated with poorer outcomes (e.g. employability, community reintegration) following discharge from inpatient hospitalizations (Cheng & Man, 2006; Robertson & Schmitter, 2016) and can result in decreased motivation (Simmonds & Fleming, 2003), compromised safety, poor community re-integration, and …


Associations Between Adolescent Cannabis Use Trajectories And Anxiety, Jacqueline C. Duperrouzel Dec 2019

Associations Between Adolescent Cannabis Use Trajectories And Anxiety, Jacqueline C. Duperrouzel

FIU Electronic Theses and Dissertations

Understanding the effects of cannabis use is critical for reducing adverse behavioral, social, and academic outcomes, particularly among adolescent users who are most at risk for cannabis related problems. Although support from both the animal and human literatures suggests the relationship between cannabis and anxiety may be associated with levels of use, much is still unknown. Thus, examining relationships between the most common mental health issue in adolescence and one of the most commonly used drugs is of great public health significance and impact. Prior longitudinal studies assessing effects of cannabis use on anxiety have not evaluated different patterns of …


Evaluation Of Cognitive Control Using Non-Gaussian Reaction Time Distributions In Fractionated Executive Function Tasks, Dmitriy Kazakov Aug 2019

Evaluation Of Cognitive Control Using Non-Gaussian Reaction Time Distributions In Fractionated Executive Function Tasks, Dmitriy Kazakov

Theses and Dissertations

The present study seeks to further investigate and refine the three-factor model of executive function (EF; Inhibition, Shifting, and Monitoring/Updating) known as the unity/diversity framework (Miyake et al., 2000). Past work in this area utilized “power” tasks that prioritize accuracy and difficulty, but real-world problem-solving incentivizes quick and efficient solutions. Ten computerized reaction time (RT) tasks: four elementary cognitive tasks (ECTs; Jensen, 1987; Santos, 2016) with progressively increasing task demands and six EF tasks. The ratio scale of RT necessitated the use of non-Gaussian statistics to better describe distribution shape, while diffusion modeling (DM; Ratcliff, 1978) was used to interpret …

The purpose of the study was to conduct two meta-analytic reviews examining cognitive functioning and schizophrenia. The first review examined the literature comparing the cognitive functioning of schizophrenic patients to healthy controls. A second review examined the cognitive functioning within schizophrenic patients, examining the differences between individuals with primarily positive symptomatology and those with primarily negative symptomatology. The first meta-analysis included 19 studies which assessed 861 schizophrenic patients and 858 healthy volunteers overall. The second meta-analysis included 10 studies comparing the cognitive functioning of 1,263 schizophrenics across positive and negative symptoms. Results of the first review indicated that healthy controls …


Ante- And Perinatal Risk Factors And Neuropsychological Outcome: Exploration Of The Role Of Multiple Birth And Acid-Base Status In Preterm Born Preschoolers, Jamie Piercy Jan 2019

Ante- And Perinatal Risk Factors And Neuropsychological Outcome: Exploration Of The Role Of Multiple Birth And Acid-Base Status In Preterm Born Preschoolers, Jamie Piercy

Wayne State University Dissertations

Increased attention to medical risk factors that precede or accompany preterm birth is necessary in order to better understand functional deficits in this vulnerable population. Children who are born preterm are subject to increased risk of neurodevelopmental deficits in the preschool years and beyond. As such, the current study aimed to gain a better understanding of the influence of two disparate biological risk factors, one antenatal and the other perinatal, on neuropsychological development. More specifically, the influence of twin gestation and low arterial pH (reflecting hypoxic risk) on neuropsychological outcomes was examined in a sample of preterm-born (before 34-weeks gestation) …

The Utility Of Neuropsychological Measures On The Differential Diagnosis Of Adhd-Inattentive Type Versus Anxiety In A Pediatric Outpatient Behavioral Health Population, Emily Stapleton

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

This study examined the differences in inattention and executive function between a group of children diagnosed with ADHD and a group diagnosed with anxiety disorders to establish differential profiles for these two disorders. This study evaluated the differences among children with ADHD and anxiety disorders, using parent-report and performance-based measures of inattention and anxiety. A retrospective chart review was completed for a total of 58 patients who met the criteria for an anxiety disorder or for ADHD-C and ADHD-I at the completion of the neuropsychological assessment. Analyses compared the ADHD group and the Anxiety group on select scales and subscales …


Underlying Contribution Of Executive Functioning To Cognition And Academic Achievement In Individuals With Dystrophinopathy, Robert Fee Sep 2018

Underlying Contribution Of Executive Functioning To Cognition And Academic Achievement In Individuals With Dystrophinopathy, Robert Fee

Dissertations, Theses, and Capstone Projects

Dystrophinopathy is a genetic disorder that results in the lack of or abnormal expression of the protein dystrophin. It is a disorder that alters cell structure and function, impacts the developing brain and brain function, presents with multi-domain cognitive deficits, and influences both mood and behavior. Cognitive impairments appear to be more localized to specific areas of functioning rather than a global deficit; however, deficits have been identified across multiple cognitive domains including language and aspects of executive functioning. A careful examination of the cognitive phenotype and its association to mutations affecting CNS isoforms is necessary to clarify the neuropsychological …


Attention Deficit Hyperactivity Disorder With Comorbid Anxiety/Depression In Adults: Impacts On Neuropsychological Functioning, Cristina Valdivieso Bain Jul 2018

Attention Deficit Hyperactivity Disorder With Comorbid Anxiety/Depression In Adults: Impacts On Neuropsychological Functioning, Cristina Valdivieso Bain

Psychology Theses & Dissertations

ADHD comorbidity with other disorders is high in the adult population (over 44% of individuals carry a second diagnosis, 25% anxiety, 18.6% in depression). Separately, these disorders can impact scores on neuropsychological assessments. Little research has investigated how comorbidity among ADHD and other disorders impacts test scores collectively. Given high rates of comorbidity between ADHD and anxiety/depressive disorders and the potential impact on neuropsychological functioning, the current study examined how these comorbid disorders collectively impact cognition. Specifically, the present study investigated differences in full scale intelligence, general ability, and cognitive proficiency on the WAIS-IV between those diagnosed with ADHD only …


Latent Class Analysis Of Malingering Classifications Using Performance And Symptom Validity Measures In A Civil Forensic Setting, Willie Floyd Mcbride Iii Jul 2018

Latent Class Analysis Of Malingering Classifications Using Performance And Symptom Validity Measures In A Civil Forensic Setting, Willie Floyd Mcbride Iii

Psychology Theses & Dissertations

The study examined the applicability of various validity measures and their ability to identify patterns of invalid responding (i.e., malingering) in an archival sample of civil forensic litigants. A latent clustering approach was used to create profiles comprised of the response patterns from validity measures of different domains including three performance validity tests (PVT), five symptom validity scales (SVT), and an embedded validity indicator (EVI). Latent class analysis (LCA) was used to enumerate subgroups of malingering and to assess differences between the subgroups.

Results demonstrated five distinct classes. The classes revealed complex patterns of symptom endorsement and performance on validity …


Examining Attentional Control And Processing Speed Deficits As Underlying Mechanisms Of Neuropsychological Impairment In Schizophrenia, Mayte Forte Dec 2017

Examining Attentional Control And Processing Speed Deficits As Underlying Mechanisms Of Neuropsychological Impairment In Schizophrenia, Mayte Forte

Graduate Masters Theses

Neuropsychological impairment is a key characteristic of schizophrenia (SZ), but its cognitive profile and underlying information processing mechanisms are not yet well understood. We compare patterns of neuropsychological functioning in 85 persons with SZ and 76 healthy controls across measures of intelligence, memory, and executive function. We then test the hypothesis that neuropsychological impairment in SZ is related to dual deficits in two related but distinct information processes: processing speed and attentional control. All research participants completed Wechsler Adult Intelligence Scale-Third Edition (WAIS-III), Wechsler Memory Scale Third Edition (WMS-III), and Wisconsin Card Sorting Test (WCST), all of which provided measures …
