Mixed Mood State Behaviors And Circadian Dysfunction Following Homocysteic Acid Treatment: Potential Animal Model For Bipolar Disorder, Lauren Evert, Gonzalo Moya, Ryann Felton, Garrett Fogo, Nicholas Rozema, Sarah Plowman, Tymi Staub

18th Annual Celebration of Undergraduate Research and Creative Activity (2019)

Bipolar disorder is a neuropsychiatric disease characterized by cyclical fluctuations of mood states between mania and depression. Circadian rhythm abnormalities and inconsistent sleep patterns are two common symptoms of bipolar disorder (Millar, Epsie, & Scott, 2004). Elevated levels of homocysteine, in the blood or cerebrospinal fluid, commonly occurs in patients with neuropsychiatric illnesses, including bipolar disorder (Bell et al., 1992; Boushey, Beresford, Omenn, & Motulsky, 1995). Homocysteic acid (HCA), an endogenous metabolite of homocysteine, has been implicated as a harmful neurotoxin and agonist of NMDA receptors. We have previously shown that postnatal administration of HCA (from postnatal day 3-21) in …

Testing The Impact Of Prebiotics On Anxiety-Like Behaviors In Aged Male Rats, Nicholai Shaw, Marny Ehmann, Kenia Urena-Gonzalez, Anna Langholz, Peter Stewart, Jared Stygstra, Emily Zolman, Erin English, Alli Lindquist, Elizabeth Woodford

18th Annual Celebration of Undergraduate Research and Creative Activity (2019)

The composition of gut microbiota has direct impacts on neural structure, neurochemistry, and behavior. Specifically, the gut microbiota has been shown to modulate anxiety-like behaviors. In addition, administering prebiotics, compounds that promote the growth of commensal bacteria, has been demonstrated to reduce anxiety and anxiety-related behaviors. However, this effect has yet to be tested in older animals despite anxiety being implicated as a most common disorder in adult populations. Therefore, this study seeks to fill this knowledge gap by investigating the link between prebiotic interventions and anxiety-like behaviors in aged populations. It was hypothesized that older rats treated with the …

Social Identity And The Use Of Ideological Categorization In Political Evaluation, Ingrid J. Haas, Christopher R. Jones, Russell H. Fazio

Department of Political Science: Faculty Publications

In this research, we address a longstanding question concerning how individuals evaluate social and political issues. We focus on the role that political self-identification plays when individuals evaluate policy statements. In a laboratory setting, participants completed a task facilitation procedure, in which they made paired sets of judgments about a series of policy statements. Relative to a control task, ideological categorization of policy statements as liberal or conservative influenced the ease of evaluation. On experimental trials that began with ideological categorization, policy evaluations that were consistent with the participant’s own ideology were made more quickly than responses that were ideologically …

The Relationship Between Depression, Sleep, And Dream Content Among College Students, Bretta Gerhard

Show Your Stripes Research and Creative Showcase

This study examined any correlation linking depression with the sleep and dream content of college students. A survey was given to Social and Behavioral Science college students at Lincoln University. The survey contained self-report questions on their level of depression, sleep habits, dream content, exercise habits, and basic demographic information. Based on prior research, we expect students who report high levels of depression to have poor sleep quality. We also expect depressed students to report a higher frequency of dreaming, and “bad” dream content then non-depressed students. Results indicating there is a relationship between depression and sleep will serve as …

Using Animal-Assisted Therapy To Treat Children With Autism Spectrum Disorder, Mary Strong

Student Research Symposium

This paper looks at the studies of the relationship between those with autism spectrum disorder and therapy animals in order to determine how effective therapy animals are in reducing problem behaviors and increasing social interaction. For this literature review, nine different studies have been reviewed to answer the research question over a variety of settings. In the nine different studies that were reviewed the animals used were either dogs, horses, or guinea pigs. These studies were used to determine which of these animals were more effective in a therapeutic setting, and more effective in the improvement of the symptoms in …

Cerebellar Vermis: Contributions To The Phenomenology Of Obsessive-Compulsive Disorder, Moriah Eve Stern

Psychology ETDs

Background: Current neurocognitive models of obsessive-compulsive disorder (OCD) implicate dysfunction in top-down inhibitory control mechanisms. Research supports alteration in the functional activity of cortico-basal ganglia-thalamo-cortical loops in OCD, as well as the inferior parietal region, posterior medial cortex, thalamus and cerebellum. The cerebellum, once only known as a region of motor coordination, is now accepted as being highly involved in cognitive regulation as well. Emerging evidence of connectivity between the posterior cerebellum and areas of the brain related to inhibitory functioning, including the basal ganglia, prefrontal, and inferior parietal regions, suggests a potential cerebellar role in OCD-symptomology. In fact, in …

Preventing Child Sexual Abuse And Juvenile Offending Through Parental Monitoring, Kelly E. Stewart

Dissertations and Theses

In this dissertation, I present three manuscripts to investigate the prevention of a range of crimes committed against, and by, youth, using parental monitoring or guardianship. In the first paper, I tested whether the routine activities of juvenile sexual offenders (JSOs) and their victims' caregivers was associated with the JSO being placed into a supervisory role, and whether subgroup differences existed in the use of modus operandi strategies between JSO supervisors and non-supervisors (Chapter II). Findings indicated that parents' need for childcare assistance predicted JSO supervisor status more strongly than perpetrators efforts to get the child alone or disruptions to …

Disaster Exposure And Mental Health Among Puerto Rican Youths After Hurricane Maria, Rosaura Orengo-Aguayo, Regan W. Stewart, Michael A. De Arellano, Joy Lynn Suárez-Kindy, John Young

Faculty and Student Publications

Importance: Quantifying the magnitude of disaster exposure and trauma-related symptoms among youths is critical for deployment of psychological services in underresourced settings. Hurricane Maria made landfall in Puerto Rico on September 20, 2017, resulting in massive destruction and unprecedented mortality. Objective: To determine the magnitude of disaster exposure and mental health outcomes among Puerto Rican youths after Hurricane Maria. Design, Setting, and Participants: Survey study in which a school-based survey was administered to each public school student at all schools in Puerto Rico between February 1 and June 29, 2018 (5-9 months after Hurricane Maria). Of the 226 808 students …

Negative And Positive Reappraisal After A Romantic Break-Up, Scarlett Horner

Theses

Romantic break-ups can cause sadness, depression, and physical symptoms. The purpose of this study is to compare two methods of alleviating heartbreak: negative reappraisal of the ex-partner and positive reappraisal of the break-up. We expected that positive reappraisal would make people feel more positive than negative reappraisal, but that negative reappraisal would make people feel less in love than positive reappraisal. We expected that negative reappraisal would reduce motivated attention as measured by the late positive potential (LPP) and how upset people were about the break-up more than positive reappraisal. In this study, 24 participants (16 female) who were upset …

Development Of The State Optimism Measure, Rachel A. Millstein, Wei-Jean Chung, Bettina B. Hoeppner, Julia K. Boehm, Sean R. Legler, Carol A. Mastromauro, Jeff C. Huffman

Psychology Faculty Articles and Research

Background

Optimism, or positive expectations about the future, is associated with better health. It is commonly assessed as a trait, but it may change over time and circumstance. Accordingly, we developed a measure of state optimism.

Methods

An initial 29-item pool was generated based on literature reviews and expert consultations. It was administered to three samples: sample 1 was a general healthy population (n = 136), sample 2 was people with cardiac disease (n = 96), and sample 3 was persons recovering from problematic substance use (n = 265). Exploratory factor analysis and item-level descriptive statistics were used to select …

The Roles Of Race And Gender In Contagious Yawning, Daroon Jalil

James Madison Undergraduate Research Journal (JMURJ)

Social psychologists often consider race to be a marker of in- or out-group status. When looking at race, implicit bias can take more subtle forms than outward racism. This study asked two research questions to better understand the psychology behind racial issues. The first question was whether the number of contagious yawns (CY) a person experiences depends on the race of the stimuli being viewed. Yawning more in response to in-group members is a phenomenon seen in chimpanzees, but it has not been studied in humans in a racial context. Black and white males and females were recruited to view …

Perceived Partner Responsiveness, Sleep And Pain: A Dyadic Study Of Military-Connected Couples, Annamarie Sophia O'Neill

Dissertations and Theses

The health-promoting influence of high-quality, supportive close relationships has been extensively documented, yet the mechanisms of this effect are less well-understood. Leading researchers have galvanized the field to test particular relationship processes and the mediating psychological processes they facilitate to pinpoint how close relationships exert their salutary effects. The purpose of this study was to investigate the influence of the intimacy process on health outcomes of sleep and pain and if this effect depends on the facilitation of psychological processes in a sample of veterans and spouses (collectively called military-connected couples; N=147). Sleep problems are highly prevalent among military-connected couples …

The Effects Of Stress Mindset Interventions On University Students' Health And Functioning, Abigail Fate

Undergraduate Honors Papers

In modern society, the overwhelming cultural narrative proclaims that stress is detrimental to health and should be limited and avoided at all costs. However, recent research has demonstrated that it is one’s stress mindset, rather than their stress level, that determines the psychological and physiological outcomes. Mindsets are lenses that simplify and order the world, and have been proven to influence daily behavioral and physiological responses to create cascading effects. Recent research has demonstrated that one’s mindset about stress is the demining factor in health, performance, and productivity in response to stressful conditions, and that these mindsets can be manipulated …

Cbt Plus Humor-Based Psychology Interventions: A Review Of The Research, Rachel Thompson

Psychology Capstone Projects

Cognitive behavioral therapy (CBT) has been demonstrated to be one of the most popular and useful psychological interventions used today (Ellis & Harper,1975; Bredemeier, Beck, & Grant, 2018; Jaya, Ascone, & Lincoln, 2018). However, a limitation of CBT is that it pathologizes behavior. Positive psychology is a supplementary theory that focuses on increasing positive emotions during psychological interventions and does not pathologize behavior. A limitation of studying positive emotions is due to the overlapping relationships between positive emotions. Positive emotions are highly related and are difficult to measure individually as opposed to negative emotions. Humor, amusement/mirth, is an observable positive …

An Investigation Into Self-Efficacy And Academically Successful Minority Students Honors Thesis, Julie Clerge

Honors Program Theses and Projects

Data from the National Center for Education Statistics have indicated that minority students have the fewest conferred degrees in the United States (Snyder, 2016). A review of the literature has attributed this phenomenon to various factors, including socioeconomic status (Harvey, 2016), parents' education level (Faye Carter, 2006) and lack of cultural congruity with the institution (Edman, 2008; Tierney, 1999; Trueba,1988). Ofcourse, there are minority students who defy the statistics and have achieved academic success. Other research has suggested that self-efficacy may be key to such success. The purpose of this study was to determine which factors are correlated with a …

Motivated To Learn: Motivational Differences In High School And University-Level Foreign Language Classroom Experiences, Roy Williams Iv

Mahurin Honors College Capstone Experience/Thesis Projects

Student motivation in the context of foreign language learning is a complex topic that influences many areas of language study. Dornyei’s L2 Motivational Self Model and the concept of future self guides give some insight into the underlying motivational orientations when used to analyze self-reported survey data regarding language learning and its perceived benefits (Dornyei & Ushioda, 2009, p. 456). This analysis brings to light some of the major differences between these two contexts, challenges the idea that they are identical or equivalent in learning outcomes, and suggests some practical application to the foreign language classroom at Western Kentucky University.

The Impact Of Childhood Abuse On Moral Development, Shayla Stogsdill

Orphans and Vulnerable Children Student Projects

Moral development is a topic which has little research to accompany it. Although there is a lack of understanding of where and how children develop morals, there is clear evidence to support that abuse in any form against a child will impact the way they learn morality. Children who experience abuse will face the physical, emotional, and mental impacts which will all contribute to the way they develop. Children also learn behaviors and ideas from caretakers and when those who are supposed to protect them do not, children will become disordered on the ideas of right and wrong. Childhood is …

Mental Health Stigma In College Students By Academic Major, Kristen Miller

Mahurin Honors College Capstone Experience/Thesis Projects

Stigma is best defined as the disapproval and shame felt by people who display characteristics not widely accepted in society. Although mental illness has become more prevalent in society through advocacy and awareness campaigns, it fails to be accepted and often individuals may feel shame that prevents them from seeking help (Dyrbye, Eacker, Durning, Brazeau, Moutier, Massie, S., et al, 2015; Givens & Tjia, 2002). Physicians in particular have been shown to have decreased help-seeking behaviors for psychological issues due to fear of professional repercussions (Dyrbye et al., 2015). Physicians also show increased levels of stress, anxiety, depression, and elevated …

Perception: Exploring Cognition And Consciousness Through Visual Art, Summer Shepherd

Mahurin Honors College Capstone Experience/Thesis Projects

The concept of consciousness has perplexed humankind for thousands of years. Countless scientists, philosophers, and artists have devoted their lifetimes to solving humanity’s questions about our relationship with the world we live within. The creative arts, such as music, theater, and visual art, can facilitate critical thinking and meaningful interpersonal communication. This paper explores the visual artwork of the author, Sunny Shepherd, through examination of historical and contemporary artistic influences on the work, as well as the psychological and philosophical concepts that fuel it. Months of research, planning, and creating went into the manifestation of the final exhibition, Metamorphosis , …

Annual Research Review: Educational Neuroscience: Progress And Prospects, Michael S.C. Thomas, Daniel Ansari, Victoria C.P. Knowland

Brain and Mind Institute Researchers' Publications

© 2018 The Authors. Journal of Child Psychology and Psychiatry published by John Wiley & Sons Ltd on behalf of Association for Child and Adolescent Mental Health. Educational neuroscience is an interdisciplinary research field that seeks to translate research findings on neural mechanisms of learning to educational practice and policy and to understand the effects of education on the brain. Neuroscience and education can interact directly, by virtue of considering the brain as a biological organ that needs to be in the optimal condition to learn (‘brain health’); or indirectly, as neuroscience shapes psychological theory and psychology influences education. In …

Intuitive Eating Promotes A Healthy Lifestyle, Krista Oezer

Classical Conversations

“Intuitive eating is a dynamic process integrating attunement of the mind, body, and food.” (Tribole and Resch 23). Essentially, intuitive eating is a way of life. By listening to inner, natural signals, intuitive eating integrates mind, body, and food for optimal health. Speaking from my own personal experience, intuitive eating truly does promote a healthy lifestyle. I don’t just know about intuitive eating; I live it. I want to share my knowledge and my experience with intuitive eating to those who have never heard of it. Although intuitive eating has gained popularity, especially among dieticians and nutritionists, it still remains …

Conformity And Cognitive Load In An Asch-Like Paradigm Study, Kaylee Baker

CUP Undergraduate Research

Objective: Conformity is an important phenomenon to examine as it has the potential to influence a vast majority of people in everyday life, especially with the current technology of social media available. Factors that affect conformity rates have had little examination in the past, but are important to note in order to fully understand this behavior of conformity. I designed this study to observe the potential effects of one such factor, cognitive load, on conformity rates in an online setting with the goal of generalizing results to the effects of social media in our contemporary society. Design: I devised an …

Reintegration Of Women Perpetrators In Post-Genocide Rwanda, Terrie Soule

Independent Study Project (ISP) Collection

Women tend to be victims during times of violence. Due to this the breadth of research on women who perpetrate violence is limited. Due to stereotypes women are more often than not seen as peace makers and nurturers, which ignores the fact that women have just as much capability as men to inflict violence. During the Genocide against the Tutsi in Rwanda, average citizens, including women, became perpetrators of genocide. As this genocide only occurred in 1994 research on the reintegration of perpetrators is limited. This paper asks the question how are women perpetrators of Genocide being reintegrated into society? …

The Word Frequency Effect In English Second Language Students: An Eye Movement Monitoring Study, Chase Alexandria Rathfoot

Senior Theses

Reading has been the subject of hundreds of thousands of studies. Reading is fundamental skill not only to an individual’s education, but to their socialization and an understanding of the behavior is a rapidly expanding area of research. One of the least understood areas of reading behavior can be found is the growing English Second Language (ESL) population – or those who are learning English after demonstrating competence in their native language. As their native language has its own unique set of properties and is presented in its own unique written form, the influence this language has on their reading …

Mind Over (What Doesn’T) Matter: De-Stigmatizing Mental Health From Senegalese Women’S Perspectives, Jenna Marks

Independent Study Project (ISP) Collection

As a matrilocal and collectivist society, Dakar is an urban space where the woman is at the center. With this in mind, it is possible to understand all the pressures women in urban Senegalese society face. Women are the center of the household, thus being responsible for the family, finances, and the social aspect of welcoming visitors. In addition to these factors, women in Senegal also deal with community expectations and responsibilities since there is larger emphasis on the community, rather than the nuclear family in Senegalese society. This paper examines how these two aspects of Senegalese society (matrilocality and …

Examining Non-Targeted Effects Of The Connect Through Play Project: Implications For Addressing Mental Health Of Underserved Middle School Youth, Jessica Dandan

Theses and Dissertations

Early adolescence is a developmental phase accompanied by several changes occurring in various biopsychosocial domains, associated with an increased vulnerability to mental and physical health problems. Youth of minority status and/or low socio- economic status have been shown to be more susceptible, as they are more likely to incur greater exposure to stressors accordingly. Coincidently, as psychological problems emerge such as internalizing disorders, physical activity engagement declines; those trends seem to persist into adulthood and have been associated with numerous negative health outcomes. Evidence points to the direct impact of physical activity, as well as, social variables such as social …
