The Role Of Dopamine Signaling In Prairie Vole Peer Relationships, Nicole S. Lee, Annaliese K. Beery

Psychology: Faculty Publications

Dopamine signaling mediates the formation of some types of social relationships, including reproductive pair bonds in the socially monogamous prairie vole (Microtus ochrogaster). In addition to these pair bonds with mates, prairie voles demonstrate selective preferences for familiar same-sex peers. The dependence of peer relationships on dopamine signaling has not been tested, and the mechanisms supporting these relationships may differ from those underlying pair bonds. We examined the effects of pharmacological manipulations of dopamine signaling on peer partner preference and socially conditioned place preference in female prairie voles. Haloperidol blockade of dopamine receptors at multiple doses did not alter selective …

A Comprehensive Study To Delineate The Role Of An Extracellular Vesicle-Associated Microrna-29a In Chronic Methamphetamine Use Disorder, Subhash Chand, Austin Gowen, Mason Savine, Dalia Moore, Alexander Clark, Wendy Huynh, Niming Wu, Katherine Odegaard, Lucas Weyrich, Rick A. Bevins, Howard S. Fox, Gurudutt Pendyala, Sowmya V. Yelamanchili

Department of Psychology: Faculty Publications

Extracellular vesicles (EVs), which express a repertoire of cargo molecules (cf. proteins, microRNA, lipids, etc.), have been garnering a prominent role in the modulation of several cellular processes. Here, using both non-human primate and rodent model systems, we provide evidence that brain-derived EV (BDE) miRNA, miR- 29a-3p (mir-29a), is significantly increased during chronic methamphetamine (MA) exposure. Further, miR-29a levels show significant increase both with drug-seeking and reinstatement in a rat MA self-administration model. We also show that EVassociated miR-29a is enriched in EV pool comprising of small EVs and exomeres and further plays a critical role in MA-induced inflammation and …

Much Ado About Missingness: A Demonstration Of Full Information Maximum Likelihood Estimation To Address Missingness In Functional Magnetic Resonance Imaging Data, Timothy D. Nelson, Rebecca L. Brock, Sonja Yokum, Cara C. Tomaso, Cary R. Savage, Eric Stice

Department of Psychology: Faculty Publications

The current paper leveraged a large multi-study functional magnetic resonance imaging (fMRI) dataset (N = 363) and a generated missingness paradigm to demonstrate different approaches for handling missing fMRI data under a variety of conditions. The performance of full information maximum likelihood (FIML) estimation, both with and without auxiliary variables, and listwise deletion were compared under different conditions of generated missing data volumes (i.e., 20, 35, and 50%). FIML generally performed better than listwise deletion in replicating results from the full dataset, but differences were small in the absence of auxiliary variables that correlated strongly with fMRI task data. However, …

Do You Copy? Post-Traumatic Stress Disorder, Auditory Processing, And Heart Rate Variability, Lyndsey Johnson

UNF Graduate Theses and Dissertations

Self -report measures used in PTSD research have the potential to limit the degree of symptom severity in military veterans, especially as there is often underreporting in this population (Kline, Falca-Dodson, Susner et al., 2010). Polyvagal Theory provides a framework assessing if physiological measures can tap into PTSD Symptomology (Porges, 1995). It is therefore hypothesized that lower scores on auditory processing tests will be positively correlated with higher scores on Stress and PTSD measures. Additionally, it is thought that lower scores on auditory processing tedts as well as higher scores on PTSD and Stress Measures will be positively correlated with …

Inside The Zoo: Captive Giraffes’ Changes In Social Ties Throughout Membership Variations, Morgan Paige Howard

UNF Graduate Theses and Dissertations

Many animals live in gregarious, fission-fusion societies where group size and composition are continually changing. Despite this, many studies have suggested that captive animals are capable of maintaining long term social bonds with others. In captive giraffes, effects on their social bonds during membership transitions have not been studied thoroughly, however, prior research does show that social bonds are a defining factor in non-captive animals. Captive giraffe social network patterns were investigated at the Jacksonville Zoo and Botanical Gardens using all occurrence behavioral data. Based on previous research, I hypothesized that when one of the individuals in the group was …

Disentangling The Role Of Self-Esteem On Eating Disorders In African American Youth, Carly Alexandria Wagner

UNF Graduate Theses and Dissertations

Self- esteem (SE) has been identified to have a significant impact on eating disorders (ED). Although previous studies have found a relationship between SE and EDs, further investigation in needed because SE and EDs affect gender, age, weight status, and ethnicity heterogeneously. In particular, there is limited research and inconsistent findings on the impact of SE on EDs in youth, males, and African Americans (AAs). This study had six aims: 1) Observe gender and age differences in SE, 2) Examine the impact of weight status on SE, 3) Observe gender and age effects on EDs, 4) Examine the impact of …

An Examination Of Romantic Relationship Initiation Strategies Utilized By Young Adults With High-Functioning Autism Or Asperger’S Syndrome, Aaron Loewy

UNF Graduate Theses and Dissertations

Individuals with and without High-Functioning Autism and Asperger’s Syndrome (HFA/AS) both show interest in sexuality and/or romance. However, the symptoms of autism, such as difficulties with indirect communication, emotional expression, signaling, theory of mind, and sexuality, can elicit difficulties that make the establishment and maintenance of romances problematic. Despite these challenges, many individuals on the spectrum have reported romantic experiences. To gain a better understanding of how such individuals formed and sustained romantic relationships, seven participants with HFA/AS were interviewed using a semi-structured approach followed by a thematic analysis of their transcribed responses. It was found that common circumstances served …

“I See What Is Right And Approve, But I Do What Is Wrong”: Psychopathy And Punishment In The Context Of Racial Bias In The Age Of Neuroimaging, Alison J. Lynch, Michael L. Perlin

Lewis & Clark Law Review

In this Article, we first consider the relevant differences between antisocial personality disorder (ASPD) and psychopathy. Then, we look at the meager cohort of federal sentencing cases in which the issue of psychopathy is even raised, and consider decision-making in this context from the perspective of implicit racial bias. Next, we present some background on the controversy of “psychopathy” diagnosis; here, we share what we call the “inside baseball” about the debate— on the differences between psychopathy and ASPD—that has rocked the world of the psychology academy. We will also analyze how our current ideas about punishment and recidivism could …

Want To Hookup?: Sex Differences In Short Term Mate Attraction Tactics, T. Joel Wade, Maryanne L. Fisher, Catherine Salmon, Carly Downs

Faculty Journal Articles

While a great deal of psychological research has been conducted on sex-specific mate choice preferences, relatively little attention has been directed toward how heterosexual men and women solicit short-term sexual partners, and which acts are perceived to be the most effective. The present research relied on an act nomination methodology with the goal of determining which actions are used by men and women to solicit a short-term “hook-up” partner (study 1) and then determine which of these actions are perceived as most effective by men and women (study 2). Using sexual strategy theory, we hypothesized that actions that suggest sexual …

Political Uncertainty Moderates Neural Evaluation Of Incongruent Policy Positions, Ingrid J. Haas, Melissa N. Baker, Frank J. Gonzalez

Center for Brain, Biology, and Behavior: Faculty Publications

Uncertainty has been shown to impact political evaluation, yet the exact mechanisms by which uncertainty affects the minds of citizens remain unclear. This experiment examines the neural underpinnings of uncertainty in political evaluation using functional magnetic resonance imaging (fMRI). During fMRI, participants completed an experimental task where they evaluated policy positions attributed to hypothetical political candidates. Policy positions were either congruent or incongruent with candidates’ political party affiliation and presented with varying levels of certainty.Neural activitywas modelled as a function of uncertainty and incongruence. Analyses suggest that neural activity in brain regions previously implicated in affective and evaluative processing (anterior …

Effects Of Social Isolation On Perineuronal Nets In The Amygdala Following A Reward Omission Task In Female Rats, Dolores B. Vazquez-Sanroman, G. Arlington Wilson, Michael T. Bardo

Psychology Faculty Publications

Negative urgency is a facet of impulsivity associated with negative affect and risky behavior that may involve the amygdala. The current study determined if social isolation during development alters negative urgency and c-Fos activity in the basolateral amygdala (BLA). Female Sprague-Dawley rats were raised in an isolated condition (IC), a standard social condition (SC), or an enriched condition (EC) and then were tested for locomotor activity, novelty place preference, and negative urgency using a reward omission task. Following performance on the reward omission task, the brains were analyzed for c-Fos expression in Ca2+ /calmodulin kinase II (CaMKII) and calbindin (CB) …

Effects Of The Glucocorticoid Receptor Antagonist Pt150 On Stress-Induced Fentanyl Seeking In Male And Female Rats, Lindsey R. Hammerslag, Emily D. Denehy, Benjamin A. Carper, Tracy L. Nolen, Mark A. Prendergast, Michael T. Bardo

Psychology Faculty Publications

Rationale Opioid use disorder (OUD) is highly comorbid with stress-related disorders, and stress can serve as a trigger for reinstatement of drug seeking. Glucocorticoid receptor (GR) antagonists such as mifepristone (RU-486) may be effective against stress-induced drug seeking. In the current study, PT150 (formerly ORG-34517), a more selective GR antagonist, was tested using two models of stress-induced drug seeking, namely footshock and yohimbine.

Methods Adult male and female Sprague-Dawley rats were trained to self-administer fentanyl (2.5 μg/kg/infusion, i.v.) in a model of escalation. Rats then received 7 days of abstinence, followed by extinction; PT150 (0, 50 or 100 mg/kg in …

Examining How Adverse Childhood Experiences And The Underlying Processes Of Trait And State Impulsivity Influence Suicidal Behavior, Julia K. Duran

Master's Theses or Doctor of Nursing Practice

ABSTRACT

Due to the effects of ACEs and impulsive behavior on mental and physical health, it is important to better understand the relationship between these two as well as how they both may influence choices, such as suicide. Numerous studies have identified impulsive behavior as a risk factor for suicide, however, recent research has identified several underlying independent processes that make up impulsivity. This study uses a broad assessment of trait and state impulsivity to gather a more discrete understanding of the underlying processes that contribute to impulsive behavior. The short version UPPS-P scale was used to measure negative urgency, …

What Influences Suffering In Silence: Examining Mental Health Stigma, Social-Cognitive Factors, And Age As Predictors Of The Willingness To Seek Professional Psychological Help, Bobbie Call

Master's Theses or Doctor of Nursing Practice

Mental health and wellness are increasingly common and popular topics discussed and researched in the world today. Recent estimates suggest that one in five adults in the United States of America experience mental health issues each year; this is estimated to be approximately 51.5 million adults (NAMI, 2020). However, despite many individuals who might suffer from mental health issues, and perhaps be diagnosed with a mental health disorder, these same individuals may not seek out the help and psychological services needed. Research exploring why people do not seek out help for their mental health should be a priority. Thus, the …

Black Girls Work Out Too! An Exploration Of Physical Activity Behaviors Of Black Women, Kimberley C. Desir

PCOM Psychology Dissertations

Lack of participation in physical activity has become an increasing public health concern in the United States. Compared to any other racial and ethnic group, Black women have the lowest prevalence of exercise. A limited amount of empirical research suggests cultural beliefs about the meaning of physical activity has a role in one’s ability to initiate and maintain a physical activity regimen. Black women face specific sociocultural factors that impact their physical activity routines. Hair care practices and maintenance has been identified as a unique barrier among Black women. This qualitative research study investigated the influence of the distinctions in …

Navigating Internalized Stigma And Identity Development In Bipolar Disorder I: A Grounded Theory Investigation., Kaylyn L. Watterson

Electronic Theses and Dissertations

Mental illness stigma occurs at multiple levels in Western societies. Internalized stigma, the application of negative stereotypes and prejudice about mental illness to self-concept, has deleterious effects on mental health for adults living with a serious mental illness. Historically, research on stigma in serious mental illness has centered on schizophrenia. Recently, researchers and clinicians have drawn attention to bipolar disorder I, an affective disorder that creates disruptions in functioning and increased risk for substance abuse and suicide. Despite the growing literature establishing the relationship between recovery in serious mental illness and identity, little is known about how adults in long-term …

Prosocial Behaviors, Gross Motor Abilities, And Soccer Skill Acquisition Of Preschool-Aged Children, Julia Gomes

PCOM Psychology Dissertations

The psychosocial and physical benefits of organized sports participation for school-aged children, collegiate athletes, and professional athletes is well understood and recognized in the literature; however, less is known about the possible benefits of sport participation for preschool-aged children. The objective of the study was to examine whether children’s involvement in an organized team sport program facilitated their gross motor, soccer skill, and prosocial development, as well as their soccer experiences. This study examined participants between the ages of 1.5 and 4.5 years old, who were first time participants of a soccer program. To examine the research questions, a paired …

Assessing Factors That Increase The Likelihood Of Naloxone Administration, Samantha Nagy

PCOM Psychology Dissertations

For more than two decades, the opioid epidemic has swept through the United States and has caused thousands of deaths every year due to opioid overdose. The Centers for Disease Control and Prevention (CDC; 2019) has reported that since 1999, over 770,000 Americans have died from overdoses. Nearly 70% of deaths in 2018 were due to opioids, 47% of which were the result of fentanyl or a non-methadone opioid and 22% were the result of heroin (CDC, 2019). As policy and treatment protocols attempt to manage those who seek treatment, the pharmaceutical industry has developed a life-saving medication that gives …

The Relationship Between Insomnia, Sleep Continuity Disturbance, Sleep-Related Daytime Dysfunction, Problem Endorsement, And Aging In A Community-Based Sample, Julia T. Boyle

PCOM Psychology Dissertations

Although older adults experience greater difficulty initiating sleep, maintaining sleep, or waking up earlier than intended, they are less likely to report that they perceive this to be a problem. The discordance between sleep disorder symptoms and the reported perception that they are troubling is unusually prevalent among older adults. This may be problematic, in that individuals who do not perceive their sleep continuity disturbances (SCDs; difficulty falling asleep, staying asleep, or waking up earlier than intended) to be problems are less likely to seek treatment. Untreated SCD has been shown to be a risk factor for the development or …

Gender Differences In Cognitive Distortions In Adults With Adhd, Laura Salciunas

PCOM Psychology Dissertations

Research has established that men and women with ADHD often manifest varying symptom constellations and are typically referred at different ages for initial evaluation. However, there is a dearth of research into how such gender differences may impact the manifestation of various psychological processes, such as cognitive distortions, even though the latter may explain up to half the variance in many clinical syndromes and personality disorders. The primary objective of this study was to identify whether there is a significant difference in the frequency of cognitive distortions between men and women with ADHD. The secondary objective was to determine the …

Effects Of Bilingualism On Executive Functioning In A Georgian-American Sample: A Latent Variables Approach. Preliminary Normative Data, Irma Campbell

PCOM Psychology Dissertations

Over the past several decades, bilingual advantage has been a topic of continuous debate among neuroscientists and linguists. Bilingualism was thought to negatively affect one’s cognitive development. Although a number of studies have shown positive effects of bilingualism on executive functioning, this view has been often challenged on methodological grounds. The current study examined monolingual and bilingual Georgian-American immigrant participants (N = 130). The results of this study showed that the bilingual individuals performed superior to the monolingual participants on three measures of executive functioning. In addition, the level of performance on measures of executive functioning that emerged in bilingual …

An Examination Of Internet Search Behavior And Completed Suicide Rates Across The United States, Marie Louise Rhoads

PCOM Psychology Dissertations

Suicide remains a leading cause of death in the US (CDC, 2021; Murphy et al., 2018). The literature has shown that individuals seeking information on personal or sensitive topics are likely to utilize the internet (Jacobs et al., 2017; Mok et al., 2015; Pew Research Center, 2019). Research also suggests that internet search behavior can be utilized to track and predict disease outbreak effectively, as well as other public health trends across the nation (Paparrizos et al., 2016; Parker, et al., 2017). Moreover, implicit associations related to suicide have been identified as strong predictors of future suicide (Millner et al., …

Obesity is a major health issue in the United States. More than two thirds of the adult population is considered to be either overweight or obese. It is the fifth leading cause of mortality in the world, with 3.4 million deaths a year. Obesity is associated with numerous medical and psychological comorbidities. There are various types of treatments for obesity, such as diets, exercise and pharmacological agents; however, bariatric surgery is one of the most effective and proven treatments for morbidly obese patients. Although the bariatric surgery success rates are high, up to 30% percent of individuals do not achieve …

The Role And Implications Of Executive Functions During The Transition To Middle School, Susan Niznik

PCOM Psychology Dissertations

The current study analyzed the relationship between executive functions and academic performance in middle school. In particular, this study analyzed the relationship between BRIEF Index and Scale scores that were compiled on a group (N = 54) of seventh graders by two seventh-grade ELA teachers and the students’ final grades in ELA, Math, Science, and Social Studies. The results showed statistically significant correlations between most of the BRIEF Indexes and Scales and the final grades, with the Metacognitive Scales showing the highest correlations. In contrast, the results showed much higher incongruence index values than expected, given the high correlations that …

Individual Differences In Social Responsiveness, Social Experiences, And Oxytocin System Genetic Variation In Depression Symptom Severity, Grace Sullivan

Department of Psychology: Dissertations, Theses, and Student Research

Social experiences including discrimination, low social support, and interpersonal conflict are reliable predictors of depression symptom severity (Costello, 1982; Monroe, Rohde, Seeley, & Lewinsohn, 1999; Phifer & Murrell, 1986). However, individual differences may buffer against or exacerbate risk (Pluess & Belsky, 2015). A more holistic and dimensional approach, in line with modern perspectives on mental health (Kircanski, LeMoult, Ordaz, & Gotlib, 2017), requires an investigation of individual differences that moderate associations of positive and negative social experiences with depression symptom severity. This dissertation assesses relative contributions of social experiences (low social support, discrimination, childhood trauma, and sexual objectification) to variation …

Fake News And Women: Fake And Real Media's Impact On Sexism In Consumer Attitudes, Alexandra C. Oropallo

Honors Undergraduate Theses

Gender-based discrimination is an issue that permeates many aspects of today's society and is influenced by numerous factors, including the presence of fake news, or emotionally driven, factually inaccurate, and misleading media. This study aimed to examine fake news' impact on consumer attitudes regarding women and to investigate how certain demographic factors relate to consumers' attitudes towards women. The current study had two main hypotheses: (1) participants exposed to fake news materials will report higher levels of both old-fashioned and modern sexism than those in other conditions and (2) participants with higher levels of sociodemographic factors such as right-wing authoritarianism …

Gastrointestinal Symptoms And Belly Pain During The Phases Of The Menstrual Cycle In Healthy Young Females, Preethashree Anbukkarasu

Honors Undergraduate Theses

There are significant differences between the incidence of gastrointestinal (GI) symptoms between males and females. A recent review found that females report having more severe GI health problems compared to males. One explanation for the higher reporting rates of GI symptoms in females could be attributed to menstrual cycle influences rather than GI processes.

This research aims to examine the relationship between how gastrointestinal (GI) symptoms experienced by women covary with the different stages of the menstrual cycle. Additionally, a secondary purpose is to determine the moderating effect of health anxiety on the severity of menstrual and GI symptoms.

Utilizing Fitts' Law To Examine Motor Imagery Of Self, Other, And Objects, Sean D. Hinkle

Honors Undergraduate Theses

Past research has indicated that motor imagery, or imagined movement, follows Fitts' law similarly to physical movement. Additionally, motor imagery has been shown to improve real motor performance in multiple contexts, showcasing a remarkable connection with real motion. The current study examines how the subject of motor imagery, imagining oneself, another person, or an object, impacts this faithfulness to real movement, specifically in following Fitts' law. Participants viewed 2D photos of a virtual environment with an "X", a humanoid, or a disc facing a gate at 6 distances and 4 widths for 24 combinations. Each combination was repeated twice randomly …
