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 …
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) …
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.
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 …
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 …
Off-Topic Verbosity And Sustained Attention Among Young Adult And Older Adult Age Cohorts, Jessica H. Helphrey
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 = …
Evaluation Of Cognitive Control Using Non-Gaussian Reaction Time Distributions In Fractionated Executive Function Tasks, Dmitriy Kazakov
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 …
Attention Deficit Hyperactivity Disorder With Comorbid Anxiety/Depression In Adults: Impacts On Neuropsychological Functioning, Cristina Valdivieso Bain
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 …
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 …
A Statistical Examination Of Impaired Performances Across Concussion Screening Instruments, Kathryn Ann Ritchie
A Statistical Examination Of Impaired Performances Across Concussion Screening Instruments, Kathryn Ann Ritchie
Master's Theses (2009 -)
It is well documented that healthy individuals routinely obtain impaired scores on neuropsychological tests, which confounds the differential diagnosis process. Relatively little is known regarding the rates at which healthy individuals obtain impaired scores on measures that are used to detect cognitive symptoms associated with sports related concussion (SRC). The current study generated expected rates of impaired performance on the Standardized Assessment of Concussion (SAC), the Automated Neuropsychological Assessment Metrics Sports Battery (ANAM), Immediate Post-Concussion and Cognitive Testing (ImPACT), and Axon Sports (Axon) neurocognitive measures by conducting Monte Carlo analyses using data obtained from a large normative sample of amateur …
Title: Parents And Teachers’ Perceptions And Clinical Diagnosis Of Autism Among White And Non-White Groups, Margaret Gopaul
Title: Parents And Teachers’ Perceptions And Clinical Diagnosis Of Autism Among White And Non-White Groups, Margaret Gopaul
Walden Dissertations and Doctoral Studies
The pervasiveness of autism has significantly increased over the past 2 decades with the 2014 Center for Disease Control and Prevention report indicating 1 in 68 children are diagnosed with Autism Spectrum Disorder (ASD). Early intervention is recommended as the most effective treatment approach. Nevertheless, previous research has indicated that White children are diagnosed with ASD about 1.5 years earlier than are Non-White children. A current gap remains in literature regarding ASD and different racial groups, and evidence has been inconclusive regarding disparities in identifying and diagnosing ASD. To fill this gap, this study investigated the relationship between child race, …
Invariant Two Component Structure Of The Rbans, Elisabeth M. Vogt
Invariant Two Component Structure Of The Rbans, Elisabeth M. Vogt
Master's Theses (2009 -)
The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS: Randolph, 1998, 2012) is a brief neurocognitive instrument used to evaluate cognitive functioning in clinical settings. While this test is used regularly, investigation of the factor structure has resulted in inconsistent findings across samples. It was hypothesized that inconsistent RBANS dimensional structures are the result of methodological differences and not solely due to unique sample characteristics. The present study utilized empirically supported extraction criteria (Parallel Analysis; Minimum Average Partial Procedure) and uniformly investigated five samples. RBANS data from four samples were previously published (Carlozzi, Horner, Yang, & Tilley, 2008; Duff, …
The Neuropsychological Deficits In Cannabis Users : Does Motivation Play A Role?, Rayna Beth Ericson
The Neuropsychological Deficits In Cannabis Users : Does Motivation Play A Role?, Rayna Beth Ericson
Legacy Theses & Dissertations (2009 - 2024)
Prior research of the neuropsychological functioning of cannabis users has yielded mixed results, in that some studies identified differences compared to non-users, while others found no group differences at all. A meta-analysis revealed a small effect of cannabis use on the cognitive domains of learning and forgetting, while domains such as attention and processing speed yielded no effect (Grant et al., 2003). However, none of the previous studies assessed the participants' motivation to perform well on the assessment, which may have influenced the results. The present study sought to determine whether motivation is differentially demonstrated in cannabis users compared to …
Neurocognitive Deficits And Functional Outcome In Bipolar Disorder, Danielle T. Bello
Neurocognitive Deficits And Functional Outcome In Bipolar Disorder, Danielle T. Bello
UNLV Theses, Dissertations, Professional Papers, and Capstones
Bipolar disorder affects approximately 1% of the population. It is a severe and debilitating illness, causing serious impairment of interpersonal, occupational and social functioning. The disorder is characterized by marked mood swings as well significant neurocognitive deficits. Based on work with other psychiatric and neurological disorders, neurocognitive deficits in bipolar disorder are expected to be strong predictors of functional capacity. However, few studies have evaluated the consequences of neurocognitive deficits in this disorder. Most available studies have focused on the clinical correlates of functional outcome, such as number of hospitalizations, age of disorder onset, and severity of symptoms. While useful, …
