A Conceptual Proposal For The Epigenetically Causal Relationship Between Parental Ptsd And Inflammatory Disease In Post Hoc Offspring., Emma Griffith Jan 2021

A Conceptual Proposal For The Epigenetically Causal Relationship Between Parental Ptsd And Inflammatory Disease In Post Hoc Offspring., Emma Griffith

Williams Honors College, Honors Research Projects

Could a combat veteran's horrific experiences in early-2000s Afghanistan have a direct, biological impact his now-adult daughter's risk of a heart attack later in her life? This concept would have been unapologetically mocked a mere twenty years ago, and it has only been in the past decade that the new field of epigenetics has revealed a distinct possibility for this event to actually take place—for parents' experiences to profoundly influence the biology of their children. The major objective of this research project is to argue for the legitimacy of this theoretical phenomenon by discussing the latest data regarding PTSD's interaction …


Relationships Between Adverse Childhood Experiences, Inflammation And Pain In Youth And Emerging Adults With Sickle Cell Disease, Angela Pascale Jan 2021

Relationships Between Adverse Childhood Experiences, Inflammation And Pain In Youth And Emerging Adults With Sickle Cell Disease, Angela Pascale

Theses and Dissertations

Sickle cell disease (SCD) is a prevalent genetic disorder involving red blood cells. SCD is a multisystem disease and is connected to various severe medical complications, including debilitating pain. Though pain and inflammation have been connected to adverse childhood experiences (ACEs) in other populations, no prior work has investigated ACEs within a SCD population. The current study examined the prevalence of ACEs as well as the association of ACEs, inflammation, and pain in a sample of youth and young adults with SCD. Utilizing the biopsychosocial model of pain, I examined individual and cumulative ACEs as possible factors relating to inflammation, …


Efficacy Of Creative Interventions In Virtual Reality, Matthew Thomas Richesin Aug 2020

Efficacy Of Creative Interventions In Virtual Reality, Matthew Thomas Richesin

Masters Theses

Engaging in creative activities is known to increase well-being by reducing levels of stress, anxiety, and improve life satisfaction. Interventions utilizing creative activities have proven to enhance therapeutic results in various mental disorders. Similarly, virtual reality has emerged as an effective method of decreasing negative aspects of mental disorders. While both creative interventions and virtual reality show promise in enhancing well-being, the efficacy of combining the two has not been explored. This study aimed to combine and compare 2-dimensional and 3-dimensional art-making on stress, anxiety, and mood in a non-clinical college student sample. To accomplish this, both physiological and self-report …

Student Beliefs About What Factors Influence Their Gpa, Emma R. Denelsbeck

Senior Honors Projects, 2020-current

There are many different factors that contribute to grade point averages (GPAs) in college. Students may attribute their academic performance and GPAs to any number of different variables such as stress levels, sleep quality and alcohol use. The current study investigated what students believed had an effect on their GPA, and if these differed based on concussion history. This study examined if students thought that concussions affected their GPA. Participants were University students who completed an online survey consisting of the Texas Evaluation of Concussion History (TECH), and the Depression, Anxiety, and Stress Scale (DASS-21). The results of a Mann-Whitney …


Cognitive Behavioral Therapy For Comorbid Posttraumatic Stress Disorder, Traumatic Brain Injury, And Associated Sleep Disturbances, Aubretia D. Snyder May 2020

Cognitive Behavioral Therapy For Comorbid Posttraumatic Stress Disorder, Traumatic Brain Injury, And Associated Sleep Disturbances, Aubretia D. Snyder

Intuition: The BYU Undergraduate Journal of Psychology

With an increasing number of veterans returning from combat with significant head injuries, research interests have begun to turn to the neuropsychological relationship between traumatic brain injury and posttraumatic stress disorder. Research has found that these dysfunctions often occur together and that both disorders may cause an exacerbation of symptoms in one another. This relationship may be negatively affected further by the presence of sleep disturbances. The complexity of this relationship requires extra consideration in regards to treatment, and cognitive behavioral therapy may be effective in treating this comorbid condition. This paper discusses the functional relationship of posttraumatic stress disorder …

Yoga To Decrease The Stress Response: Gentle Yoga Encourages Faster Decline In Salivary Cortisol Concentrations Following Participation In Tsst, Tabetha Gaile Hopke Aug 2019

Yoga To Decrease The Stress Response: Gentle Yoga Encourages Faster Decline In Salivary Cortisol Concentrations Following Participation In Tsst, Tabetha Gaile Hopke

MSU Graduate Theses

Short-term, activation of the human stress response system is beneficial as it prepares the body to deal with stressors at hand (McEwen & Stellar, 1993). If this system is overactive or chronically active however, it can negatively impact health and longevity (Cohen, Janicki-Deverts, & Miller, 2007). According to a review conducted by Ross & Thomas (2010) implementation of a yoga practice has been shown to down-regulate the stress response system. The present study aimed to expand on current research involving yoga for stress reduction by exploring whether participation in gentle yoga could decrease the stress response more quickly than naturally …


The Effects Of Relationships On Ans Function And Wellness, Olivia M. Maples Apr 2019

The Effects Of Relationships On Ans Function And Wellness, Olivia M. Maples

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

The quality of relationships and social networks plays a vital role on well-being (Feeney & Collins, 2015). Social support is linked to positive biological profiles in that social support protects against the negative effects of changes in cardiovascular, neuroendocrine, and immune function. Furthermore, when exploring Autonomic Nervous System (ANS) function, higher heart rate variability has been shown to reflect a psychophysiological state compatible with social interaction (Quintana, Guastella, Outhred, Hickie, & Kemp, 2012). Social support has been shown to buffer against the negative effects of life stressors (Cohen & Wills, 1985), and ultimately, mortality (Holt-Lunstad, Smith, & Layton, 2010). In …


Redefining Burnout: Exploring Common Conceptualizations And The Neurophysiology Of Chronic Stress To Establish An Integrated Allostatic Model, Danny A. Guzzi Apr 2019

Redefining Burnout: Exploring Common Conceptualizations And The Neurophysiology Of Chronic Stress To Establish An Integrated Allostatic Model, Danny A. Guzzi

Dissertations

Burnout is a widely researched stress-related phenomenon associated with numerous adverse outcomes for employees and organizations. Unfortunately, burnout is not well understood and research to this point has been flawed due to a lack of consensus on the definition, dimensionality, and context of the construct. Prevalent conceptualizations of burnout have been criticized for being arbitrarily developed without solid theoretical foundation and for failing to clearly distinguish burnout from depression or other work-related conditions such as compassion fatigue, secondary traumatization, and vicarious traumatization. The current project first examines relevant literature to identify commonalities among prevalent burnout conceptualizations. Then relevant stress research …


Lateralized Difference In Tympanic Membrane Temperature: Emotion And Hemispheric Activity, Ruth E. Propper, Tad T. Brunyé Mar 2019

Lateralized Difference In Tympanic Membrane Temperature: Emotion And Hemispheric Activity, Ruth E. Propper, Tad T. Brunyé

Ruth Propper

We review literature examining relationships between tympanic membrane temperature (TMT), affective/motivational orientation, and hemispheric activity. Lateralized differences in TMT might enable real-time monitoring of hemispheric activity in real-world conditions, and could serve as a corroborating marker of mental illnesses associated with specific affective dysregulation. We support the proposal that TMT holds potential for broadly indexing lateralized brain physiology during tasks demanding the processing and representation of emotional and/or motivational states, and for predicting trait-related affective/motivational orientations. The precise nature of the relationship between TMT and brain physiology, however, remains elusive. Indeed the limited extant research has sampled different participant populations …


Findings Of An Effect Of Gender, But Not Handedness, On Self-Reported Motion Sickness Propensity, Ruth E. Propper, Frederick Bonato, Leanna Ward, Kenneth Sumner Mar 2019

Findings Of An Effect Of Gender, But Not Handedness, On Self-Reported Motion Sickness Propensity, Ruth E. Propper, Frederick Bonato, Leanna Ward, Kenneth Sumner

Ruth Propper

Discrepant input from vestibular and visual systems may be involved in motion sickness; individual differences in the organization of these systems may, therefore, give rise to individual differences in propensity to motion sickness. Non-right-handedness has been associated with altered cortical lateralization of vestibular function, such that non-right-handedness is associated with left hemisphere, and right-handedness with right hemisphere, lateralized, vestibular system. Interestingly, magnocellular visual processing, responsible for motion detection and ostensibly involved in motion sickness, has been shown to be decreased in non-right-handers. It is not known if the anomalous organization of the vestibular or magnocellular systems in non-right-handers might alter …


A Combined Fmri And Dti Examination Of Functional Language Lateralization And Arcuate Fasciculus Structure: Effects Of Degree Versus Direction Of Hand Preference Author Links Open Overlay Panel, Ruth E. Propper, Lauren J. O'Donnell, Stephen Whalen, Yanmei Tie, Isaiah Norton, Ralph O. Suarez, Lilla Zollei, Alireza Radmanesh, Alexandra Golby Mar 2019

A Combined Fmri And Dti Examination Of Functional Language Lateralization And Arcuate Fasciculus Structure: Effects Of Degree Versus Direction Of Hand Preference Author Links Open Overlay Panel, Ruth E. Propper, Lauren J. O'Donnell, Stephen Whalen, Yanmei Tie, Isaiah Norton, Ralph O. Suarez, Lilla Zollei, Alireza Radmanesh, Alexandra Golby

Ruth Propper

The present study examined the relationship between hand preference degree and direction, functional language lateralization in Broca’s and Wernicke’s areas, and structural measures of the arcuate fasciculus. Results revealed an effect of degree of hand preference on arcuate fasciculus structure, such that consistently-handed individuals, regardless of the direction of hand preference, demonstrated the most asymmetric arcuate fasciculus, with larger left versus right arcuate, as measured by DTI. Functional language lateralization in Wernicke’s area, measured via fMRI, was related to arcuate fasciculus volume in consistent-left-handers only, and only in people who were not right hemisphere lateralized for language; given the …


Superior Episodic Memory Is Associated With Interhemispheric Processing, Ruth E. Propper, Stephen D. Christman Mar 2019

Superior Episodic Memory Is Associated With Interhemispheric Processing, Ruth E. Propper, Stephen D. Christman

Ruth Propper

The dependence of episodic memories on interhemispheric processing was tested. In Experiment 1, positive familial sinistrality (FS+; e.g., the presence of left-handed relatives) was associated with superior episodic memory and inferior implicit memory in comparison with negative familial sinistrality (i.e., FS-). This reflected a greater degree of interhemispheric interaction in FS+ participants, which was hypothesized as facilitating episodic memory. In Experiment 2, the authors directly manipulated inter- versus intrahemispheric processing using tests of episodic (recognition) and semantic (lexical decision) memory in which letter strings were presented twice within trial blocks. Semantic memory was superior when the 2nd presentation went to …


Why Girls? The Importance Of Developing Gender-Specific Health Promotion Programs For Adolescent Girls, Amanda Birnbaum, Tracy R. Nichols Mar 2019

Why Girls? The Importance Of Developing Gender-Specific Health Promotion Programs For Adolescent Girls, Amanda Birnbaum, Tracy R. Nichols

Amanda Birnbaum

Adolescence is a time when many girls begin to develop unhealthy behaviors that can affect myriad short- and long-term health outcomes across their lifespan.2There is evidence that smoking, physical activity, and diet are habituated during adolescence, and some physiologic processes of adolescence, such as peak bone mass development, have direct effects on future health.3-4 Establishing healthy practices, beliefs and knowledge among adolescent girls will decrease morbidity and mortality among adult women and potentially affect the health of men and children through women’s role as healthcare agents. This paper provides a brief review of lifestyle health behaviors among women and girls …


Self-Management Strategies Mediate Self-Efficacy And Physical Activity, Amanda Birnbaum, Rod K. Dishman, Robert W. Motl, James F. Sallis, Andrea L. Dunn, Greg J. Welk, Ariane L. Yung, Carolyn C. Voorhees, Jared B. Jobe Mar 2019

Self-Management Strategies Mediate Self-Efficacy And Physical Activity, Amanda Birnbaum, Rod K. Dishman, Robert W. Motl, James F. Sallis, Andrea L. Dunn, Greg J. Welk, Ariane L. Yung, Carolyn C. Voorhees, Jared B. Jobe

Amanda Birnbaum

Self-efficacy theory proposes that girls who have confidence in their capability to be physically active will perceive fewer barriers to physical activity or be less influenced by them, be more likely to pursue perceived benefits of being physically active, and be more likely to enjoy physical activity. Self-efficacy is theorized also to influence physical activity through self-management strategies (e.g., thoughts, goals, plans, and acts) that support physical activity, but this idea has not been empirically tested.


Relations Among Maternal And Paternal Behavior And Children's Stress Biology, S.K. Jiaming Lin, Stacey N. Doan, John Milton Jan 2019

Relations Among Maternal And Paternal Behavior And Children's Stress Biology, S.K. Jiaming Lin, Stacey N. Doan, John Milton

Scripps Senior Theses

Parenting behavior has been shown to have a wide range of effects, influencing children’s psychological and biological stress outcomes. Most research focuses on maternal parenting behaviors, with few studies observing the effects of paternal behaviors or the influence of both parents on their children. In this study, the relationship between maternal and paternal parenting behaviors was examined in its association to predict children’s cortisol levels. Cultural differences in parenting styles was also observed. American (N=86) and Chinese (N=97) families participated in the study, with parents reporting their behaviors. Children’s cortisol was collected during a stressor task and correlational analysis was …


Short-Term Abstinence Effects In Experienced Electronic Cigarette Users, Nicholas J. Felicione Jan 2019

Short-Term Abstinence Effects In Experienced Electronic Cigarette Users, Nicholas J. Felicione

Graduate Theses, Dissertations, and Problem Reports

Nicotine/tobacco dependence is a problem that negatively affects health at an individual and population level. Nicotine/tobacco dependence may be best assessed by measuring withdrawal symptoms of a nicotine/tobacco user who abstains from use. Withdrawal symptoms experienced by cigarette smokers are well characterized, including deficits in attention and memory, as well as self-reported cravings, urges, and other symptoms. While withdrawal in cigarette smokers has been studied extensively, little is known about dependence and withdrawal associated with newer products, such as electronic cigarettes (ECIGs). ECIGs can deliver nicotine comparably to tobacco cigarettes, indicating that they may have the potential to cause dependence. …


Portion Size Influences Intake In Samburu Kenyan People Not Exposed To The Western Obesogenic Environment, Kevin P. Myers, Jeffrey M. Brunstrom, Peter J. Rogers, Jon D. Holtzman Jan 2019

Portion Size Influences Intake In Samburu Kenyan People Not Exposed To The Western Obesogenic Environment, Kevin P. Myers, Jeffrey M. Brunstrom, Peter J. Rogers, Jon D. Holtzman

Faculty Journal Articles

For people in the modernized food environment, external factors like food variety, palatability, and ubiquitous learned cues for food availability can overcome internal, homeostatic signals to promote excess intake. Portion size is one such external cue; people typically consume more when served more, often without awareness. Though susceptibility to external cues may be attributed to the modernized, cue-saturated environment, there is little research on people living outside that context, or with distinctly different food norms. We studied a sample of Samburu people in rural Kenya who maintain a traditional, semi-nomadic pastoralist lifestyle, eat a very limited diet, and face …


Dispositional Empathy And Autonomic Reactivity During A Comfort Interaction, Alaina G. Tiani Jan 2019

Dispositional Empathy And Autonomic Reactivity During A Comfort Interaction, Alaina G. Tiani

Graduate Theses, Dissertations, and Problem Reports

The purpose of the current study was to examine the association between dispositional (trait) empathy and autonomic reactivity during dyadic interactions among women enrolled in undergraduate psychology courses. The primary research question was: do individuals who are deemed higher in dispositional empathy according to self-report exhibit differential autonomic reactivity patterns during a task in which they are asked to comfort another student experiencing emotional distress than those who are deemed lower in dispositional empathy? The literature on this relation has been mixed and has utilized photos or videos to evoke emotion; thus this study sought to examine the relation between …


The Effects Of Oral Contraceptives On Mood And Affect: A Meta-Analysis, Erica M. Motter Jan 2019

The Effects Of Oral Contraceptives On Mood And Affect: A Meta-Analysis, Erica M. Motter

Cal Poly Humboldt theses and projects

Combined oral contraceptive (COC) pills are widely used by women of reproductive age, but there is still little conclusive evidence that exists about the mood-related side effects associated with their use. This meta-analysis examined the relationship between oral contraceptive use and mood effects such as depression and anxiety to determine what role, if any, that COCs may have in the worsening or improvement of women’s mood when taking them. Effect sizes compared the differences in women’s mood scores before taking COCs and after one or more cycles of use. Seventeen studies made up of 25 individual samples contributed 71 effect …

To encourage forward movement in this burgeoning research area, measurement and design issues in the study of PA and health are discussed, as are the connections between PA and a range of different health outcomes. Plausible biological, social, and behavioral pathways that allow for positive feelings to get under the skin and influence physical wellness are …


A Functional Neuroimaging Study Of Self-Regulatory Control In Adults With Gambling And Obsessive-Compulsive Disorders, Nidhi Parashar Sep 2018

A Functional Neuroimaging Study Of Self-Regulatory Control In Adults With Gambling And Obsessive-Compulsive Disorders, Nidhi Parashar

Dissertations, Theses, and Capstone Projects

Objective: Recent findings suggest phenomenological similarities across gambling and obsessive-compulsive disorders. The key similarity between the disorders is the failure to inhibit or control a repetitive behavior (or urges to engage in a behavior) and intrusive thoughts. Our current understanding of the neural pathophysiological mechanisms linking gambling and obsessive-compulsive disorders is limited. Thus, the aim of the present study was to examine the functioning of frontostriatal brain regions that support self-regulatory control in adults with gambling and obsessive-compulsive disorders.

Methods: The study compared functional magnetic resonance imaging blood oxygen level dependent response in 19 adults with pathological gambling (PG), …


Wellness And Karate, Cristina Kumpf Aug 2018

Wellness And Karate, Cristina Kumpf

Electronic Theses and Dissertations

The promotion of wellness is an integral part of the counseling field and is considered to be a central focus to the counseling process (Barden, Conley, & Young, 2015; Myers, 1992). The counseling profession adopted the concept of wellness because it harmonizes with many of the founding principles of the ACA and is seen as a process of questing toward optimal health and well-being in body, mind, and spirit (Barden, Conley, & Young, 2015; Myers, 1992; Myers, Sweeney, & Witmer, 2000). Additionally, ACA Code of Ethics (2014) state that counselors “engage in self-care activities to maintain and promote their own …

Treating Adhd With Suggestion: Neurofeedback And Placebo Therapeutics, Robert T. Thibault, Samuel Vassière, Jay A. Olson, Amir Raz May 2018

Treating Adhd With Suggestion: Neurofeedback And Placebo Therapeutics, Robert T. Thibault, Samuel Vassière, Jay A. Olson, Amir Raz

Psychology Faculty Articles and Research

Objective: We propose that clinicians can use suggestion to help treat conditions such as ADHD. Methods: We use EEG neurofeedback as a case study, alongside evidence from a recent pilot experiment utilizing a sham MRI scanner to highlight the therapeutic potential of suggestion-based treatments. Results: The medical literature demonstrates that many practitioners already prescribe treatments that hardly outperform placebo comparators. Moreover, the sham MRI experiment showed that, even with full disclosure of the procedure, suggestion alone can reduce the symptomatology of ADHD. Conclusion: Non-deceptive suggestion-based treatments, especially those drawing on accessories from neuroscience, may offer a safe complement and potential …


The Ush2a Gene: An Analysis Of Ultrasonic Vocalizations In A Mouse Model Of Usher Syndrome Type 2, Kiana R. Akhundzadeh May 2018

The Ush2a Gene: An Analysis Of Ultrasonic Vocalizations In A Mouse Model Of Usher Syndrome Type 2, Kiana R. Akhundzadeh

Honors Scholar Theses

Usher syndrome type 2 is a complex autosomal recessive genetic disorder that is characterized by moderate to severe congenital sensorineural hearing loss, the onset of retinitis pigmentosa in the second decade of life, and in some cases, vestibular dysfunction. Mutations in the USH2A gene account for 85% of cases of type 2. The USH2A gene is responsible for encoding the protein usherin, which has an important role in the development and function of inner ear hair cells and retinal photoreceptors. Until recently, it has been believed that carriers of the USH2A mutation were phenotype free. However, recent data has suggested …


Detecting Suicide Risk From Wristworn Activity Tracker Data Using Machine Learning Approaches, Pallavi Atluri Apr 2018

Detecting Suicide Risk From Wristworn Activity Tracker Data Using Machine Learning Approaches, Pallavi Atluri

Electrical Engineering Theses

Suicide is a prevalent cause of death worldwide and depression is a primary concern of many suicidal acts. It is possible that an individual during depression never has any suicidal thoughts at all. On the other hand, some individuals in stable condition with no apparent symptoms of depression feel urges to commit suicide (suicidal ideation). Many such individuals never let anyone know what they are feeling or planning. Suicidal ideation considered an important precursor to suicidal acts.

Detecting the suicide risk in individuals with mood disorders is a major challenge. The current clinical practice to assess suicide risk in these …


Mental Disorders As Brain Disorders: The Impact On Stigma Of Neuroscience-Based Mental Health Education, Katherine Tighe Mar 2018

Mental Disorders As Brain Disorders: The Impact On Stigma Of Neuroscience-Based Mental Health Education, Katherine Tighe

Honors Theses

Stigmatization of mental illness is undoubtedly detrimental to those with mental health concerns as it limits employment, self-esteem and social support (Markowitz, 1998). In effort to combat the issue of stigma, previous research has evaluated the effectiveness of education as a method to reduce stigma in a college sample; finding that peer-led presentations are effective in reducing stigma (Kosyluk et al., 2016). The current study sought to evaluate the effectiveness of neuroscience-oriented presentation for reducing the stigma of mental illness among college students. Researchers asked 53 Union College students to complete seven-item Social Distance Scale (SDS; Penn et al., 1994) …
