Cognitive Functioning In Well-Controlled Asthma, Erin Walsh
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
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
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
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 Effects Of Traumatic Brain Injury On Empathy And Quality Of Life, Nicholas James Pek
The Effects Of Traumatic Brain Injury On Empathy And Quality Of Life, Nicholas James Pek
Theses, Dissertations and Culminating Projects
Physical, emotional, cognitive, and social problems can all result from a traumatic brain injury. The focus of this present research was to investigate individuals with moderate-to-severe TBI who lack empathy and how that lack in empathy might impact their quality-of-life. Individuals with moderate-to-severe TBI between ages 18 and 65 (N=39) completed questionnaires including the Quality of Life after Brain Injury (QOLIBRI) and Empathy Quotient (EQ) as part of a larger study. A correlational analysis was completed between the total scores on the EQ and total scores on the QOLIBRI before splitting the participants into groups. A relationship between total scores …
Videoconference Administration Of The Delis-Kaplan Executive Function System, Zachary T. Stine
Videoconference Administration Of The Delis-Kaplan Executive Function System, Zachary T. Stine
Doctor of Psychology (PsyD)
Neuropsychological assessments rely on standardization, reliability, validity, and normative data to increase the accuracy of clinicians’ interpretations (Lezak et al., 2012). One particular assessment that focuses on examining comprehensive executive functioning is the Delis-Kaplan Executive Function System (D-KEFS; Delis et al., 2001). Videoconference is gaining in use to provide services within multiple healthcare domains to increase access to care and convenience, potentially reduce costs, and sustain patient satisfaction (Brearly et al., 2017). The literature has shown support for the growing field of telehealth neuropsychology (Brearly et al., 2017); however, many neuropsychological assessments, such as the D-KEFS, have not been normed …
The Relationship Between Maternal Emotion Socialization And Child Executive Functioning And Behavior: Exploring The Moderating Role Of Cortisol, Mayela Norwood
The Relationship Between Maternal Emotion Socialization And Child Executive Functioning And Behavior: Exploring The Moderating Role Of Cortisol, Mayela Norwood
CMC Senior Theses
In the early years of life, the development of children’s executive functioning (EF) and behavior regulation are critical to their later growth and self-sufficiency. Previous studies have indicated that one pathway by which children learn to regulate their emotions is through their immediate social environments (de Cock et al., 2017). Parents, in particular, play a significant role in the development of their children‘s emotion regulation and executive functioning (Fernandes et al., 2022). At the same time, physiological responses to stress also matter. Cortisol, the end product of the hypothalamic-pituitary-adrenal axis, has also been associated with children’s executive functioning and behavior …

The Impact Of Cannabis Use On Neuropsychological And Neural Biomarkers Of Treatment Response In Schizophrenia Spectrum Disorders, Melanie B. Thies
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
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
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
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 …
Culture And Language Influence How Hispanics/Latinos In The U.S. Think About Themselves Through Time, Alicia Camuy
Culture And Language Influence How Hispanics/Latinos In The U.S. Think About Themselves Through Time, Alicia Camuy
Senior Theses and Projects
Culture has been implicated in episodic memory, but this has not been explored in episodic future thought. Episodic information helps to form an identity. Thus, this is an exploratory study to identify unique ways in which Spanish-English Hispanic/Latino populations remember and project to the future, perceive themselves over time, and perceive the passage of time. Participants (n = 50) were healthy bilingual Hispanics/Latinos living in the U.S. tested over Zoom. Materials included background information, an acculturation scale, Temporal Focus Scale (TFS), and Thinking About Life Experiences (TALE) Scale. A time estimation measure and Pre- and Re- experiencing Mental Events (PRIME) …
A Comparison Of Teleneuropsychological And Traditional Neuropsychological Battery Factor Structures, Alison Datoc
A Comparison Of Teleneuropsychological And Traditional Neuropsychological Battery Factor Structures, Alison Datoc
Theses and Dissertations
This study compared the factor structures of a traditional neuropsychological battery, administered in-person, and a teleneuropsychological battery, administered remotely. Participants were divided into two groups dependent on test condition (i.e., in- person or remote). Individuals in the in-person test condition group (n = 100) were selected from a sample of individuals who were assessed in-person in a previous archival study, and individuals in the remote testing condition group (n = 100) were assessed via teleneuropsychology in their home environment.
Two Exploratory Factor Analyses (EFA) using Principal Component Analysis (PCA) method were conducted on the T-scores and scaled scores of each …
Neural Correlates And Neuroanatomy Of Juvenile And Adult Contextual Fear Memory Retention, Natalie Odynocki
Neural Correlates And Neuroanatomy Of Juvenile And Adult Contextual Fear Memory Retention, Natalie Odynocki
Legacy Theses & Dissertations (2009 - 2024)
AbstractFear is an evolutionarily conserved mechanism that allows an organism to discern potential harm and act accordingly by engaging in defensive behaviors. While fear is an adaptive response, dysregulation of fear by means of a traumatic event can lead to psychiatric conditions such as post-traumatic stress disorder (PTSD). Animal research using rodents in Pavlovian context fear conditioning experiments allows for the ability to study the underlying neural circuitry of threat-appropriate and aberrant fear learning and memory that may contribute to PTSD. However, despite reports that women are more than two times more likely to develop PTSD compared to men, the …
Cancer Related Cognitive Impairment In Breast Cancer Patients: Guidelines For Neuropsychological Evaluation And Management, Ali Al-Humadi
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.
Investigation Of A Misophonia And Fluid Intelligence Relationship: Sound Spectrum Variation Impact On Fluid Intelligence Task Responses, Leslie Watson
Investigation Of A Misophonia And Fluid Intelligence Relationship: Sound Spectrum Variation Impact On Fluid Intelligence Task Responses, Leslie Watson
Master's Theses
ABSTRACT Studies of misophonia have not assessed the impact of music and sound complexity on intelligence in individuals with misophonia. Edelstein et al. (2013) have provided work which pools trigger sound characteristics including sound repetitiveness yet does not include a substantial music subcategory. Utilizing the Cattell–Horn–Carroll model of intelligence, the current study explores the nature of music and music complexity on fluid intelligence, as described by Sternberg (2012). The hypotheses for this study focused on the relationship that complexity and music might have with misophonia. The rate of misophonia in the Mechanical Turk population was hypothesized to be 20%. The …
Association Of Early Life Stressors With Deficits In Child And Adolescent Cognitive Functioning, Emily M. Deming
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, …
Cerebellum-Seeded Functional Connectivity Changes In Trait-Anxious Individuals Undergoing Attention Bias Modification Training, Katherine Elwell
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 …
Golf Brain: A Neuropsychological Study Of Performance In Competition, Taylor S. Broughton
Golf Brain: A Neuropsychological Study Of Performance In Competition, Taylor S. Broughton
Doctor of Psychology (PsyD)
Golf, as a sport, has been described by its masters as a mental game first and a technical skill second. Many players logged countless practice hours only to find suboptimal performance in tournaments; when it matters the most. I investigated the relationship between executive functioning specific to decision-making under anxious arousal and golfers’ performance under anxious arousal. I used a repeated measures design including variety of executive functioning tests to examine participants’ abilities. Participants were recruited from western Oregon including collegiate golfers and university students, and were grouped into non-golfers and golfer groups based on whether they played golf and …
The Roles Of Cardiovascular Disease And Depression In The Relationship Between Respiratory Disease And Neuropsychological Functioning In Older Adults, Alexander J. Gordon
The Roles Of Cardiovascular Disease And Depression In The Relationship Between Respiratory Disease And Neuropsychological Functioning In Older Adults, Alexander J. Gordon
Theses and Dissertations
The pathophysiology of severe respiratory diseases, such as asthma and chronic obstructive pulmonary disease (COPD), supports the theory that oxygen deprivation to the brain may impact the brain’s execution of cognitive functions. Imaging studies also suggest that neuroanatomical changes in areas of the brain responsible for cognitive processes may be associated with respiratory diseases. Research in this area has failed to conclude definitively, especially in an older adult population, which is more likely to experience comorbid depression and cardiovascular disease, universally acknowledged predictors of poorer cognitive performance, the extent of the relationship between respiratory illness and cognitive functioning. The current …
Executive Functioning And Purpose In Life Among Emerging Adults In College, Alexis Kaylyn Liberto
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
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 …
Neuropsychological Implications Of Nocturnal Hypoxemia In Sickle Cell Disease, Sheena Ram
Neuropsychological Implications Of Nocturnal Hypoxemia In Sickle Cell Disease, Sheena Ram
Theses and Dissertations
Neuropsychological impairments have been observed in both individuals with sleep-disordered breathing and in individuals with sickle cell disease (SCD), but there has been little research on the potential effect of sleep-disordered breathing on neuropsychological function in individuals with SCD. This study aims to examine the effect nocturnal oxygen desaturations have on neuropsychological functioning in individuals with sickle cell disease when compared to those with non-sickle anemia and healthy controls. Thirty-four participants with SCD, 18 non-sickle anemia controls (ACTL), and 29 healthy controls (CTL), ages 9 to 63 years, participating in an IRB-approved Children’s Hospital Los Angeles study of cerebral blood …
The Relation Between Hyperlipidemia, Hypertension, And Downstream Cognitive And Neuroanatomical Function, Victor James Wasserman
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 …
Network Analysis Of Cognitive Symptom Domains In Alzheimer's Disease (Ad), Abigail Rose Baily
Network Analysis Of Cognitive Symptom Domains In Alzheimer's Disease (Ad), Abigail Rose Baily
UNLV Theses, Dissertations, Professional Papers, and Capstones
Alzheimer’s Disease (AD) is a degenerative neurological disease process that results in cognitive and functional declines and ultimately results in death. The pattern and course of cognitive and functional decline has been well characterized in AD, however little is known about the interactions between the symptoms. Network Analysis is a recently developed mathematical approach of examining the interactions between symptoms, by exploring the covariance of symptoms. The current study utilized network analysis to examine the multivariate structural dependencies among cognitive domains known to be affected in Alzheimer’s disease. The sample consisted of 864 older adults (60-90 years old), selected from …
The Association Of Aerobic Fitness With Resting State Functional Connectivity And Verbal Learning And Memory In Healthy Young Adults, Kyle Joseph Jennette
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
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 …
An Exploration Of Atypical Recovery From Pediatric Mild Traumatic Brain Injury (Mtbi), Kathryn Ann Ritchie
An Exploration Of Atypical Recovery From Pediatric Mild Traumatic Brain Injury (Mtbi), Kathryn Ann Ritchie
Dissertations (1934 -)
Mild traumatic brain injury (mTBI) is a significant public health concern, particularly for children and adolescents. Existing research suggests that pre-injury and injury-related factors influence recovery. The current study simultaneously considered variables relevant to recovery from pediatric mTBI, including pre-injury diagnoses, symptom burden, neuropsychological and emotional functioning, performance validity, and medical service utilization in an archival sample of children referred to a multidisciplinary concussion clinic. Consistent with a broad literature, female sex and initial symptom burden predicted referral for neuropsychological evaluation. Initial symptom burden also predicted neuropsychological performance and service utilization. A meaningful proportion of the sample reported clinically significant …
The Relationship Between Neuropsychological Functioning, Biomarker Av-1451, And Subjective Memory Impairment In A Cognitively Normal Sample, Amberrose Reale-Caldwell
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 …
