Evaluation Of An Eeg Task For Detecting Latent Infections, Ryan Weels, Savanah Bishun, Bruce Brown Jun 2019

Evaluation Of An Eeg Task For Detecting Latent Infections, Ryan Weels, Savanah Bishun, Bruce Brown

Journal of Undergraduate Research

Ultimately our goal is to develop methods for diagnosing neuropsychiatric illnesses through measurement and analysis of the electrophysiological stream of consciousness. In this project we test how well EEG adaptations of the Sternberg (1966) memory search task and the n-back cognitive task can discriminate between individuals who are positive for Herpes-simplex-1 and healthy controls.


Do Support Groups For Medical Patients Reduce Risk For Mortality? A Meta-Analytic Review, Connor Workman, Dakota Jake, Daniel Rallison, Timothy Smith, Phd, Julianne Holt-Lunstad, Phd Jun 2019

Do Support Groups For Medical Patients Reduce Risk For Mortality? A Meta-Analytic Review, Connor Workman, Dakota Jake, Daniel Rallison, Timothy Smith, Phd, Julianne Holt-Lunstad, Phd

Journal of Undergraduate Research

Recent scientific findings show that loneliness is found among the highest predictors of mortality. This information could prove to be a major influence on future interventions for medical patients. However, the literature is inconclusive on how best to implement these findings in the real world. Given that research is limited, a meta-analysis of all appropriate scientific articles was performed to find how social support affected mortality in a medical setting.


Role Of Electrical Synapses In Dopamine Transmission In The Brain, Josh Nelson, Seth Stapley, Scott Steffensen Jun 2019

Role Of Electrical Synapses In Dopamine Transmission In The Brain, Josh Nelson, Seth Stapley, Scott Steffensen

Journal of Undergraduate Research

Drug addiction has long been a major detriment to society. Its pervasive effects can tear apart the lives of addicted individuals. Many of these individuals go without seeking professional help. In 2015, 22.7 million Americans (8.6 percent) needed treatment for a problem related to drugs or alcohol, but only about 2.5 million people (0.9 percent) received treatment at a specialty facility. This may be due to inadequate treatment methods and therapies in use by professionals. The goal of this project is to better understand the mechanism of dopamine (DA) transmission in the brain in order to develop more effective treatment …


The Effects Of Caffeine On Visual Attention In Caffeine-Naïve Participants, Eva Tveten, Steven Luke Jun 2019

The Effects Of Caffeine On Visual Attention In Caffeine-Naïve Participants, Eva Tveten, Steven Luke

Journal of Undergraduate Research

Controversy exists concerning the effects of caffeine on cognitive function. One of the greatest challenges in resolving this controversy stems from the fact that caffeine is the most widely used drug in the United States, consumed daily by a majority of the population. The frequent and widespread use of caffeine means that most research participants are already using it regularly. When this is the case, effects attributed to caffeine in studies can just as easily be explained by relief from withdrawals. What seems to be an improvement in cognitive function in participants who are given caffeine may simply be a …


Multimodal Neuroimaging Of Insomnia During Non-Rapid Eye Movement Sleep (Mni_Nrem), Daniel Kay Jun 2019

Multimodal Neuroimaging Of Insomnia During Non-Rapid Eye Movement Sleep (Mni_Nrem), Daniel Kay

Journal of Undergraduate Research

The impact of insomnia on brain regions/networks during sleep may represent mechanisms through which insomnia contributes to the risk for mood disorders. As a first step toward understanding the risk relationship linking insomnia to mood disorders, this study will utilize functional magnetic resonance imaging (fMRI) with multimodal techniques to investigate alterations in brain regions and networks during wake and NREM sleep in patients with insomnia relative to good sleeper controls. We also intend to investigate the pathophysiology of insomnia across 8 units of analysis by combining these data with Dr. Kay’s larger study, the MNI_RDoC (IRB #16377). The units of …


Social Learning In The Digital Age: The Impact Of Technoference On Mother-Child Attachment And Social Skills, Danielle N. Zayia Jun 2019

Social Learning In The Digital Age: The Impact Of Technoference On Mother-Child Attachment And Social Skills, Danielle N. Zayia

Theses and Dissertations

Research has shown links between parenting practice and children’s social development. However, there is little research examining the role of parental technology use or technoference, which is the disruption caused by technology. In this study, parental technology use, child attachment style, maternal insularity, and children’s development of social skills were examined. Rating scales examining theses variables were completed by 80 mothers-child dyads between the ages of 18 and 50 with children between 6 and 10 years old. Confirmatory factor and measurement invariance analyses were conducted to examine and confirm the psychometric properties of each scale used in this study. Linear …


An Examination Of The Effects Of Post-Identification Feedback On Jurors, Daniella Cash Jun 2019

An Examination Of The Effects Of Post-Identification Feedback On Jurors, Daniella Cash

LSU Doctoral Dissertations

Post-identification feedback (PIF) occurs when witnesses are given feedback following their identification choices. This feedback has been shown to alter witnesses’ retrospective judgments regarding their witnessing experience (e.g., they are more confident that they made a correct identification). PIF effects are robust; they impact witnesses’ memory of their experience, and also appear to act as confirmation to jurors who are asked to assess witness reliability. A current recommendation for eyewitness procedures is that identifications should be recorded and shown to jurors at trial, but this might be harmful if jurors are also negatively impacted by this suggestive feedback. The goal …


Self-Affirmation Theory And The Change Of Perception Of Self And Threats, Isaac Wicker Jun 2019

Self-Affirmation Theory And The Change Of Perception Of Self And Threats, Isaac Wicker

Theses and Dissertations

In today’s American culture, people experience high rates of distress and depression (Kessler et al., 2005). Self-affirmation theory has been shown to help people reduce stress and defensiveness in the face of a wide variety of stressors. A shortcoming of self-affirmation exercises is that there are barriers to using them in naturalistic settings. One such barrier is that the affirmation content needs to be regulated so that it is not closely related to the salient stressor or else the effects of the affirmation could be counteracted. The current study sought to use a prompt-guided value selection for the self-affirmation exercise …


The Influence Of Spirituality, Moral Reasoning, And Personality Factors On Misogyny, Rachel Mcpherson Jun 2019

The Influence Of Spirituality, Moral Reasoning, And Personality Factors On Misogyny, Rachel Mcpherson

The Pegasus Review: UCF Undergraduate Research Journal

Sexism, prejudice or discrimination typically against women, is an attitude that causes emotional distress and can negatively affect women's psychological and physical health. Studies have shown that psychological distress heightens when women are subjected to sexist events (Szymanski, Gupta, Carr, & Stewart, 2009). Sexism exists in the classroom, workplace, and politics, and is virtually inescapable for women (Miner-Rubino, 2007). It is common for women who are in positions of power to be unjustly branded with cruel epithets (Manne, 2016). Despite the modernity of today's culture and progression of gender equality, sexism is still a prevalent issue. This study assesses underlying …


Development Of A New Scale For Evaluating Authoritarianism, Melodie Spiegel Jun 2019

Development Of A New Scale For Evaluating Authoritarianism, Melodie Spiegel

The Pegasus Review: UCF Undergraduate Research Journal

Despite the existence of multiple scales purporting to measure degree of authoritarianism as a personality trait, there exists disagreement within current research as to whether these measures reliably measure the three hypothesized domains of authoritarian submission, aggression, and traditionalism. This study focuses on the development of a new scale in response to methodological and validity concerns of previously-used measures. The new scale provides a reliable measure of authoritarian belief within the tested sample of college-aged students. Factor analysis of responses to the items of the new measure also provides evidence of the multidimensionality of authoritarianism as a construct. Further, significant …


Spontaneous Mimicry Of Emotional Facial Expressions As A Function Of Trait Sadism, Cathleen Fleury, Mary Ritchie, Derek Mitchell Jun 2019

Spontaneous Mimicry Of Emotional Facial Expressions As A Function Of Trait Sadism, Cathleen Fleury, Mary Ritchie, Derek Mitchell

Western Research Forum

Using electromyography (EMG), it has been shown that facial muscles imperceptibly mirror the facial expressions of others, a phenomenon referred to as spontaneous facial mimicry. Facial mimicry may be involved in empathy processing, and is impaired in several empathy deficit disorders. It was previously believed to follow the direct-matching principle, a theory postulating that spontaneous facial mimicry involves the observer mirroring their partner’s expression exactly. However, several recent studies have demonstrated that context and individual differences may be influencing factors of spontaneous facial mimicry. In the present study, we propose to investigate the relationship between facial mimicry and empathy through …


The Combinative Role Of Traits Cheerfulness And Seriousness In Predicting Resiliency And Well-Being: A Moderated Mediation Model, Chloe Lau, Fransceca Chiesi, Lital Yosopov, Don Saklofske Jun 2019

The Combinative Role Of Traits Cheerfulness And Seriousness In Predicting Resiliency And Well-Being: A Moderated Mediation Model, Chloe Lau, Fransceca Chiesi, Lital Yosopov, Don Saklofske

Western Research Forum

Cheerfulness can be defined as the habitual tendency to possess a cheerful composure both alone and in social interactions (Ruch, Köhler, and van Thriel, 1996; 1997). While the construct of cheerfulness has been of significant interest to researchers, little attention has been given to trait seriousness. Both cheerfulness and seriousness have important clinical implications; for instance, depressed patients have reported lower cheerfulness and higher seriousness compared to healthy controls (Falkenberg, Jarmuzel, Bartels, & Wild, 2011). Thus, the present study seeks to address these traits collectively, providing a more comprehensive understanding of their roles in predicting resiliency and well-being. It was …


Oxytocin And Social Affiliation: A Study Of The Genetic Underpinnings Behind Social Behavior In Rhesus Macaques, Ryno Kruger, J. Dee Higley Jun 2019

Oxytocin And Social Affiliation: A Study Of The Genetic Underpinnings Behind Social Behavior In Rhesus Macaques, Ryno Kruger, J. Dee Higley

Journal of Undergraduate Research

Studies suggest that social relationships play a critical role in physical and mental health1, with effect sizes similar to that seen for smoking and alcohol abuse. Those experiencing real or perceived social isolation show higher rates of mortality3, while those with stronger social relationships show decreased rates of mortality4. Also, genetic variation has been associated with the degree of individual sociability2. The serotonin (5-HT) and oxytocin (OT) systems are believed to influence social behavior6,2. The serotonin transporter (SERT) gene codes for efficiency of the serotonin system, with the long (L) allele associated with greater efficiency, when compared to the short …


The Impact Of Perceived Support On Multi-Cultural And International College Students In Utah, Erin Kaseda, Wendy Birmingham Jun 2019

The Impact Of Perceived Support On Multi-Cultural And International College Students In Utah, Erin Kaseda, Wendy Birmingham

Journal of Undergraduate Research

College is a time in which young adults face a large number of stressors, including academic adjustment, education and career planning, evolving family relationships, struggles with financial independence, dating and marriage, and exposure to new cultures and ideas.1 Previous studies have suggested that college students face high levels of stress, with 75% of college students reporting themselves as moderately stressed and 12% as highly stressed.2 Prolonged stress can have serious effects on both mental and physical health, including an increased likelihood of developing symptoms of depression and anxiety, decreased immune function, sleep disruption, poor cardiovascular health, increased body mass, and …


“A” For Effort: Rewarding Effortful Retrieval Attempts Improves Learning From General Knowledge Errors In Women, Damon Abraham, Kateri Mcrae, Jennifer A. Mangels Jun 2019

“A” For Effort: Rewarding Effortful Retrieval Attempts Improves Learning From General Knowledge Errors In Women, Damon Abraham, Kateri Mcrae, Jennifer A. Mangels

Publications and Research

Previous research has shown that the prospect of attaining a reward can promote task engagement, up-regulate attention toward reward-relevant information, and facilitate enhanced encoding of new information into declarative memory. However, past research on reward-based enhancement of declarative memory has focused primarily on paradigms in which rewards are contingent upon accurate responses. Yet, findings from test-enhanced learning show that making errors can also be useful for learning if those errors represent effortful retrieval attempts and are followed by corrective feedback. Here, we used a challenging general knowledge task to examine the effects of explicitly rewarding retrieval effort, defined as a …


Effects Of Childhood Trauma On Neurological Development And Mental, Physical Health In Adulthood, Sara Mckissick Jun 2019

Effects Of Childhood Trauma On Neurological Development And Mental, Physical Health In Adulthood, Sara Mckissick

D.U.Quark

Unfortunately, childhood maltreatment and trauma are prevalent in society. As awareness grows, so does the research on the long-term effects early exposure to traumatic events has on the developing person. Socioeconomic hardships, psychopathologies, and cognitive deficiencies correlate with early childhood adverse experiences. This review will compare normal neurological activity and development to that of children who have experienced childhood trauma. It will also further explore various factors such as the level of trauma, the onset of exposure, duration or recurrence of trauma experienced. Finally, this review will examine the effects that manifest themselves in adulthood to further understand the detrimental …

Acute Ethanol Decreases Infiltration Of Macrophages Across The Blood-Brain Barrier, James Brundage, Jake Lattin, Dr. Scott Steffensen Jun 2019

Acute Ethanol Decreases Infiltration Of Macrophages Across The Blood-Brain Barrier, James Brundage, Jake Lattin, Dr. Scott Steffensen

Journal of Undergraduate Research

Alcohol addiction affects the lives of millions of people worldwide. In the US alone, an estimated 28 million are currently undergoing treatment to recover from the effects of alcohol abuse at the cost of over 249 billion dollars. The disease has dire consequences for those affected, as well as their families and communities. Despite this, the mechanism of alcohol addiction formation remains a question. One prominent theory relies on the mesolimbic circuitry of the brain, commonly referred to as the reward circuit. This region is made up of two key brain regions, the Nucleus Accumbens (NAc) and the Ventral Tegmental …


Sex Differences In Ethanol Modulation Of Dopamine Release In The Mesolimbic Reward System, Mandy Parsons, Justin Bowman, Scott Steffensen Jun 2019

Sex Differences In Ethanol Modulation Of Dopamine Release In The Mesolimbic Reward System, Mandy Parsons, Justin Bowman, Scott Steffensen

Journal of Undergraduate Research

Alcohol abuse disorder is a ubiquitous problem affecting 15.1 million people in the United States, almost 10 million men and more than 15 million women (SAMHSA, 2015). The prevailing view of addiction, including alcohol addiction, is that an increase of the neurotransmitter dopamine in the nucleus accumbens within the brain has powerful rewarding effects. The purpose of this project was to evaluate the effects of alcohol on dopamine release in female rats during the three phases of the estrus cycle in order to determine if alcohol is more rewarding at different points in the female hormone cycle.


Randomized Trial Of A Single-Session Growth Mind-Set Intervention For Rural Adolescents’ Internalizing And Externalizing Problems, Jessica L. Schleider, Jeni L. Burnette, Laura Widman, Crystal L. Hoyt, Mitchell J. Prinstein Jun 2019

Randomized Trial Of A Single-Session Growth Mind-Set Intervention For Rural Adolescents’ Internalizing And Externalizing Problems, Jessica L. Schleider, Jeni L. Burnette, Laura Widman, Crystal L. Hoyt, Mitchell J. Prinstein

Jepson School of Leadership Studies articles, book chapters and other publications

Objective. Adolescents living in rural regions of the United States face substantial barriers to accessing mental health services, creating needs for more accessible, non-stigmatizing, briefer interventions. Research suggests that single-session “growth mindset” interventions (GM-SSIs)—which teach the belief that personal traits are malleable through effort—may reduce internalizing and externalizing problems in adolescents. However, GM-SSIs have not been evaluated among rural youth, and their effects on internalizing and externalizing problems have not been assessed within a single trial, rendering their relative benefits for different problem types unclear. We examined whether a computerized GM-SSI could reduce depressive symptoms, social anxiety symptoms, and …


The Effects Of Helicobacter Pylori On Cognition: A Report, Kenric Gordon, Thomas Petersen, Dawson Hedges Jun 2019

The Effects Of Helicobacter Pylori On Cognition: A Report, Kenric Gordon, Thomas Petersen, Dawson Hedges

Journal of Undergraduate Research

Last year we applied for an ORCA grant for our study of the effects of Helicobacter Pylori on Cognition. Helicobacter Pylori is a bacterium that causes ulcers in the stomach. It has also been implied to cause decreased cognitive functioning. (Berrett, Erickson, Brown, Hedges, 2016) Due to this, it is necessary to discover how Helicobacter Pylori effects cognition and how we can tell through EEG whether someone has Helicobacter Pylori.


Testing The Psychometric Properties Of Positive Psychology Measures, Olivia Hansen, Jared Warren Jun 2019

Testing The Psychometric Properties Of Positive Psychology Measures, Olivia Hansen, Jared Warren

Journal of Undergraduate Research

Positive psychology is the rigorous and empirical study of well-being, human strengths, and human flourishing, and the experiences, traits, and institutions that lead to those aims. It began as a rigorous subdomain of psychology in the late 1990’s. Up until this point, the field of psychology had focused largely on pathology and on the weaknesses of the psyche, and positive psychology has shifted to emphasize that psychology has much more it can offer if it looks past just the very worst of human experiences. Positive psychology is rapidly expanding and gaining popularity, and a huge volume of research is being …


Psychosocial Empowerment Group Creation And Implementation Among Malawi Women, Libby Evans, Benjamin Ogles Jun 2019

Psychosocial Empowerment Group Creation And Implementation Among Malawi Women, Libby Evans, Benjamin Ogles

Journal of Undergraduate Research

Research has shown that most women in Malawi will experience some form of trauma or adversity in their lifetime, and that such adversity can increase rates of mental illness and instability by as much as 15-20% (Saxena, 2017). Simple psychosocial groups and trainings have been shown to increase psychological resilience and prevent and/or heal mental instability. The term psychological resilience is defined as the way a person adapts well in the face of hard times, adversity, trauma, tragedy, or stress. Resilience can be taught through a few simple skills. The goal of this project was to get a better understanding …


A Comparison Of Gender Ratio, Military Culture, And Organizational Climate As Determinants Of The Sexual Harassment Of Women And Of Men In Eight Government Organizations, Alex Calder, Bruce Brown, Robert Ridge Jun 2019

A Comparison Of Gender Ratio, Military Culture, And Organizational Climate As Determinants Of The Sexual Harassment Of Women And Of Men In Eight Government Organizations, Alex Calder, Bruce Brown, Robert Ridge

Journal of Undergraduate Research

The United States government spends millions of dollars each year in relation to incidences of sexual harassment. Far more important, however, is the psychological toll on individuals who experiences sexual harassment. Organizations function most effectively when people of all levels of the organization feel physically and emotionally safe. Unfortunately, sexual harassment occurs more frequently in the military as compared to other government agencies. Previous research has left clues about why this may be. Some have suggested that the military necessarily breeds an aggressive culture, which in turn could lead to more aggressive misdeeds. Elsewhere, researchers have demonstrated that organizational climate …


Partnering With A Different Faith: Muslim American Women’S Experiences, Beyza Sinan Jun 2019

Partnering With A Different Faith: Muslim American Women’S Experiences, Beyza Sinan

Seton Hall University Dissertations and Theses (ETDs)

The events of September 11, 2001 critically impacted the identity of Muslim Americans in the United States and spurred attention to their experiences within the psychological literature. Prior literature has rarely explored these individuals’ within-group differences, defined Muslim American identity as bicultural, or explored experiences of being in a romantic relationship. This study was intended to address the gaps in the literature by focusing on the bicultural identity and the experience of interfaith relationships among Muslim American women. The following research questions guided this study: 1) How do Muslim American women experience their romantic relationship with a non-Muslim partner? 2) …


Emotional Clarity In Young Adults: Operationalization, Measurement, And Associations With Mental Health Outcomes, Madeline D W Noland Jun 2019

Emotional Clarity In Young Adults: Operationalization, Measurement, And Associations With Mental Health Outcomes, Madeline D W Noland

Clinical Psychology Dissertations

Emotional clarity (EC) refers to the ability to identify, understand, and distinguish one’s emotions (Gohm & Clore, 2000). The literature suggests that EC is highly related to emotion regulation (ER), such that individuals with higher EC are more likely to use adaptive ER strategies and individuals with lower EC are more likely to use maladaptive ER strategies (Vine & Aldao, 2014). EC has been measured with both self-report measures and physiological tasks. Due to the limitations of both self-report measures and physiological tasks, I aimed to develop a behavioral measure of EC using the concordance between change in individuals’ physiological …


Destined To Dominate? Exploring The Link Between Prenatal Androgens And Dominance Rank In Rhesus Monkeys, Alexander Baxter, Dr. J. Dee Higley Jun 2019

Destined To Dominate? Exploring The Link Between Prenatal Androgens And Dominance Rank In Rhesus Monkeys, Alexander Baxter, Dr. J. Dee Higley

Journal of Undergraduate Research

Prenatally, androgens are responsible for masculinizing the developing male fetus. Prenatal androgen exposure (PAE) also shapes male brain functioning and organization, and is the main underlying influence underlying sexually dimorphism, to a certain extent even in adulthood. Through its effect on the brain, PAE can influence personality and behavior, likely contributing to gross sex differences in these traits, as well as within-sex variation (see Manning, 2011). One of the most commonly used biomarkers used to study PAE is the second-to-fourth-finger length ratio (2D:4D ratio). In humans, males tend to have a longer ring finger and shorter pointer finger (i.e., a …


University And College Counseling Centers: Collegiate Athletes Shifting Changes In Mental Health Risk, Lilly Bautista, Rachelle Clayson, Jared Klundt, Davey Erekson Jun 2019

University And College Counseling Centers: Collegiate Athletes Shifting Changes In Mental Health Risk, Lilly Bautista, Rachelle Clayson, Jared Klundt, Davey Erekson

Journal of Undergraduate Research

Within the college population, student athletes are often considered a unique population for mental health concerns. There are more student athletes than ever before, with over 460,000 students participating in the National Collegiate Athletic Association (NCAA, 2016). Student athletes have access to more resources than the typical student, but the amount of utilization and extent of these resources can vary greatly. Specifically, the utilization of university and college counseling centers.


Seeing The World Through Humility-Tinted Glasses: Exploring Social Cognitive Explanations For Outcomes Of Humility, Chayce Baldwin, Dr. Robert Ridge Jun 2019

Seeing The World Through Humility-Tinted Glasses: Exploring Social Cognitive Explanations For Outcomes Of Humility, Chayce Baldwin, Dr. Robert Ridge

Journal of Undergraduate Research

In recent years, psychological research on humility has burgeoned, highlighting the influence of humility in prominent aspects of life such as well-being (Toussaint & Webb, 2017), interpersonal relationships, and prosocial behaviors (Hilbig, Zettler, & Heydasch, 2012), as well as self-control (De Vries et al., 2013). Particularly, studies have connected humility to traits and behaviors such as agreeableness and conscientiousness (Lee & Ashton, 2004), cooperation (Hilbig et al., 2012), and helpfulness (Exline & Hill, 2012), painting a picture of humility as predominantly prosocial and characterized by low self-focus. Indeed, many researchers highlight low self-focus as a defining attribute of humility, with …


Personality And Process: The Role Of Dyadic Homophily, Christina N. Falcon Jun 2019

Personality And Process: The Role Of Dyadic Homophily, Christina N. Falcon

USF Tampa Graduate Theses and Dissertations

This paper focuses on understanding the development of quality of intra-team processes. Utilizing semester-long project teams, social networks were used to measure the information sharing and coordination between all pairs of members with the teams. Dyadic-level homophily on the personality traits of agreeableness, extraversion, and openness to experience were used to predict the quality of these dyadic processes. Additionally, data from 11 weeks were used to examine whether the personality-process relationships change during the life cycle of the team.
