The Impact Of Perceived Discrimination On Mental And Physical Health Among The Hispanic Immigrant Population, Cheyla Tabares Cuesta Apr 2025

The Impact Of Perceived Discrimination On Mental And Physical Health Among The Hispanic Immigrant Population, Cheyla Tabares Cuesta

Undergraduate Theses

Discrimination has profoundly shaped the lives of individuals within disadvantaged communities, but its impact on mental and physical health has often been overlooked. In this project, I review literature on perceived discrimination based on immigrant status and its effects on psychological and physical health and examine a potential mediator and moderator of these relationships. Specifically, the relationships between immigration-based discrimination and both mental health and physical health may be mediated by perceived stress, meaning that discrimination may lead to higher stress levels, which results in poorer health outcomes. Furthermore, these relationships may be moderated by psychological resilience; individuals with higher …

Alcohol withdrawal is characterized by various symptoms that include pain and negative affect in the absence of the drug. The neural underpinnings of these behaviors are not entirely understood, but orexin has emerged as a candidate target for the treatment of substance use disorders. Here, we explored changes in orexin system-related gene expression in brain regions important for mediating reward and stress, including the ventral tegmental area (VTA) and extended amygdala (including the central amygdala, nucleus accumbens shell, and bed nucleus of the stria terminalis), in adolescent and adult female Wistar rats following chronic alcohol exposure. We observed higher numbers …

Role Of Eye-Tracking Technology And Software Algorithms In Enhancing Adhd Detection And Diagnosis: A Systematic Literature Review, Lauren E. Perkins Mar 2025

Role Of Eye-Tracking Technology And Software Algorithms In Enhancing Adhd Detection And Diagnosis: A Systematic Literature Review, Lauren E. Perkins

Honors College Theses

This systematic literature review explores the role of eye-tracking technology and software algorithms in enhancing the detection and diagnosis of ADHD. ADHD, a neurodevelopmental disorder affecting both children and adults, is traditionally diagnosed through behavioral assessments, which may lack objectivity. Recent studies suggest that eye-tracking, specifically focusing on saccades, fixations, and blink rates, offers the potential for more accurate and objective measures of ADHD. The review examines clinical trials, observational studies, and machine learning research to assess the correlation between ADHD and eye movement patterns. Results indicate that individuals with ADHD exhibit distinct eye movement patterns, which can be quantified …

Effects Of Social Isolation On Locus Coeruleus Opioid Receptor Expression And Affective Behavior, John Tkaczynski, Jordan Riser, Maya Patel, Nicole Shellenbarger, Jin Park, Daniel Manvich, Daniel J Chandler

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Social isolation is a stressor that impairs homeostatic neuroendocrine functions and is associated with the development of several mood disorders characterized by persistent negative affect. Persistent feelings of loneliness have been growing public health concerns for several years and were greatly exacerbated by the onset of the COVID-19 pandemic. The problem has grown so severe the U.S. Surgeon General recently declared loneliness to be an epidemic health concern that is associated with poor mental and somatic health outcomes. Therefore, identifying mechanisms of neuroadaptation that contribute to the development of persistent negative affect is a critical step in the identifying better …

Probing For Intentions: The Early Readiness Potential Does Not Reflect Awareness Of Motor Preparation, Jake Gavenas, Aaron Schurger, Uri Maoz Feb 2025

Probing For Intentions: The Early Readiness Potential Does Not Reflect Awareness Of Motor Preparation, Jake Gavenas, Aaron Schurger, Uri Maoz

Psychology Faculty Articles and Research

Voluntary actions are typically preceded by the readiness potential (RP), a negative midfrontal electroencephalography (EEG) deflection that begins ~2 s before movement. What cognitive and neural process the RP reflects and how it relates to conscious intention remain unclear due to conflicting findings. We investigated the neural basis and cognitive significance of the RP in a novel probe-based paradigm. Contrary to prior reports, we found that pre-probe RP buildups were not related to reported awareness of motor preparation. Computational modeling suggested that the best explanation for these results is via metacognitive access to stochastic accumulation. Reported preparation was also related …


A Compelling Case Of The Use Of Electroconvulsive Therapy In Severe Treatment Resistant Depression With Suicidality, Neha Narayanan, Ryan Tam, James Mead Feb 2025

A Compelling Case Of The Use Of Electroconvulsive Therapy In Severe Treatment Resistant Depression With Suicidality, Neha Narayanan, Ryan Tam, James Mead

Advances in Clinical Medical Research and Healthcare Delivery

Treatment-resistant depression is a condition that occurs when an individual, experiencing major depressive disorder episodes, has failed the first line of treatment with medication therapy of adequate dose and duration. This is important to be addressed as there is a high likelihood of progression to having thoughts and an intended plan for suicide. Electroconvulsive therapy is a recommended option for those who have failed medication therapy, but it has been controversial in its use due to its stigma and side effects of memory impairment. Here, we present a case of a patient who had undergone several sessions of ECT with …

Assessment Of Omentin-1 In Diabetic Nephropathy And Insulin Resistance Individuals In Type 2 Diabetic Patients, Nabaa Najam. Abd Zaid Alshamiry, Nibras Hussain. Abdulsada Al-Ghuraibawi

Maaen Journal for Medical Sciences

A case-control study at AL-Sadar Teaching Hospital/Al-Najaf Center found a negative correlation between serum omentin-1 levels and diabetic nephropathy, suggesting early detection of microvascular complications. Long-term diabetes increases the risk of complications, including nephropathy, which worsens over time. High blood pressure is a common comorbidity among diabetics, and careful glycemic control is necessary in advanced stages. Omentin-1 plays a role in enhancing insulin sensitivity and glucose metabolism, but further investigation is needed to determine diabetic nephropathy severity in T2DM patients.

Lifetime History Of Concussions In Relation To Blind Perceptual Distance Estimation Ability, Mackenzie K. Miller Jan 2025

Lifetime History Of Concussions In Relation To Blind Perceptual Distance Estimation Ability, Mackenzie K. Miller

Honors Undergraduate Theses

This study examined the relationship between visuospatial estimation and a lifetime history of concussions. Current literature on concussions investigates visuospatial working memory and estimation ability separately, but not conjointly. In order to examine this relationship, a novel neuropsychological task was designed to measure visuospatial estimation ability in working memory, named the Perceptual Estimation Test (PET). This novel task was designed with three variations that would increase in complexity as they progressed, and each variation would include three trials. Participants were scored on their accuracy performance during the PET. Participants aged 18-25 were recruited from students attending the University of Central …


Forgiveness Of Self And Others: A Group Approach To The Treatment Of Ptsd And Other Trauma Related Experiences, Jarrod A. Mask Jan 2025

Forgiveness Of Self And Others: A Group Approach To The Treatment Of Ptsd And Other Trauma Related Experiences, Jarrod A. Mask

Psychology Doctoral Specialization Projects

Forgiveness is often misinterpreted as the act of forgetting what happened or offering one’s offender the ability to redeem themselves for their wrongdoings. This is simply not the case. Rather, forgiveness is the process of the individual making the unprovoked choice to release their resentment in their own voyage towards living a free and happy life without being imprisoned from the emotions un-forgiveness produces. Forgiveness, as it may be a necessary process for the individual is to attain a sense of peaceful acceptance and liberation from their pain, is not an easy process. Providing a peer-based support system in the …

An Investigation Of The Physiological And Behavioral Correlates Of Mental Imagery, Matthew Daniel Carroll Jan 2025

An Investigation Of The Physiological And Behavioral Correlates Of Mental Imagery, Matthew Daniel Carroll

Graduate Theses/Dissertations

Many conventional theories hold mental imagery to be fundamental to self-regulation. Recently, a current of research into mental imagery has developed, with the terms anaurelia and aphantasia being coined for the inability to experience, respectively, auditory and visual thought content, yet little is known about the impact that such individual differences have on persons’ lives. The present experiment was performed in order to test the hypotheses that self-regulation and mental imagery positively correlate and that mental imagery mediates the correlation of resting heart-rate variability and self-regulation. Self-regulation was measured via a self-report questionnaire (the Short Self-Regulation Questionnaire), as was mental …

Honors Undergraduate Theses

Caffeine is the most consumed and widely used psychoactive substance in the world. Whether someone uses caffeine or not, expectations about use can be influential to some degree. Expectancies exist everywhere and are extremely influential in all aspects of life. Regarding drug use, expectancies can affect behavior, outcomes, and one’s experience with the drug. Caffeine is no exception, caffeine expectancies have been seen to play a role in several actions such as the development, maintenance, and reinforcement of caffeine use. This study examined latent use profiles of caffeine and relationships between the profiles and the activation of caffeine expectancies. Multidimensional …


Assessing The Relationship Between Perceived Psychological And Physical Pain In Adults With Orthopedic Pain, Daniel C. Karimi Dehkordi Jan 2025

Assessing The Relationship Between Perceived Psychological And Physical Pain In Adults With Orthopedic Pain, Daniel C. Karimi Dehkordi

Honors Undergraduate Theses

Suicide remains a public health concern in the U.S., particularly among individuals experiencing chronic pain and psychological distress. This cross-sectional study investigated the relationship between perceived physical and psychological pain in 41 adults with chronic orthopedic conditions. The relationship between other risk and protective factors and perceived levels of pain distress was also examined. Results showed a significant positive correlation between psychological distress and physical pain (r(39) = 0.388, p < .05) and psychological distress and depressive/anxiety symptoms (r (39) = 0.477, p < .01). Psychological distress was moderately associated with feelings of hopelessness (r (39) = 0.403, p < .01), however, the relationship between physical pain and hopelessness was weak and nonsignificant (r (39) = -0.06, p = .71). Contrary to expectations, emotional support did not buffer the effects of psychological distress (r (39) = 0.07, p = 0.66). Mediational analysis confirmed that emotional support did not influence the relationship between physical pain and psychological distress (Beta (β) = -0.969, p = 0.572; Sobel Z = 0.5598, p = 0.575). Age was not correlated with psychological distress (r (39) = -0.24, p = 0.13) or mental health symptoms (r (39) = -0.05, p = .77). While there was no significant difference across sex, males reported higher mental health symptomatology and psychological distress scores than female counterparts. These findings underscore the direct impact of physical pain on psychological distress and challenge assumptions about the protective role of social support. The study highlights the need for integrated, multidisciplinary interventions targeting both physical and psychological pain to mitigate suicide risk among individuals with chronic orthopedic conditions. Future research should iii explore alternative support mechanisms and resilience-building strategies to address the complex interplay of pain, distress, and suicidality.

The Effect Of Need For Cognition & Need For Affect On Human Reliance And Artificial Intelligence Interactions, Aliyah Mcgowan

Doctoral Dissertations and Master's Theses

Abstract

With the increased use of Artificial Intelligence (AI) automations in fields like medical diagnoses and mental health queries, there are concerns regarding an individual’s trust and reliance on the technology. Reliance on AI output may lead an individual to accept inaccurate or incorrect information without further analysis. Trust may influence reliance and trust formation may be a product of affective processing. This study investigated the relationship between Need for Affect (NFA), Need for Cognition (NFC), and trust and reliance on AI interactions. Participants were assessed on the NFA scale for willingness to approach or avoid emotional stimuli, the NFC …


Effects Of High-Frequency Repetitive Transcranial Magnetic Stimulation On Impulse Control Disorders In Patients With Parkinson’S Disease On Dopamine Replacement Therapy, Katherine Muksuris Jan 2025

Effects Of High-Frequency Repetitive Transcranial Magnetic Stimulation On Impulse Control Disorders In Patients With Parkinson’S Disease On Dopamine Replacement Therapy, Katherine Muksuris

Graduate Theses, Dissertations, and Problem Reports (ETD)

Parkinson’s Disease (PD) is a debilitating neurodegenerative disorder that causes motor deficits, cognitive impairment, and depression. The mainstay treatment for motor symptoms is dopamine replacement therapy (DRT). DRT takes the form of levodopa or dopamine receptor agonists (DAs) and can be associated with impulse control disorders (ICDs). Currently, the approach to mitigating these side effects is to decrease or stop DRT, which may cause motor symptoms to return, making the management of the disorder more difficult. Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive neuromodulation treatment for multiple disorders, including its approved use for smoking cessation. It has also shown …

The Gut-Brain Axis: Investigating The Effects Of Diet, Physical Activity, And Prior Adversity On Anxiety Via Autonomic Nervous System, Jenna L. Pennella

UNF Graduate Theses and Dissertations

Previous literature has highlighted a bidirectional relationship between the gut and brain called the gut-brain axis (de Punder & Pruimboom, 2015; Hill et al., 2008; Leistner & Menke, 2020). The current study aimed to investigate directional relations between different stressors (e.g. poor diet, vigorous activity, and prior adversity) and anxiety and how interactions with gut issues and autonomic dysfunction may impact these relationships. Based on previous literature, we examined (a) physical activity and diet as moderators of stress and anxiety as well as stress and GI symptoms, (b) GI symptoms as a mediator between various predictors (i.e., diet, stress, physical …
