Individual Differences In The Dopaminergic Reward System: The Effect Of Genetic Risk On Neural Reward Sensitivity And Risky Choice, Heather E. Soder

USF Tampa Graduate Theses and Dissertations

When making decisions, individuals evaluate several possible outcomes of their choice; however, some display heightened reward sensitivity, despite the potential for future negative consequences, which can lead one to make risky choices. Rewards are processed in the mesolimbic dopamine reward system, and this system is in part modulated by genetic polymorphisms that are associated with dopamine transmission. The current study tested if genetic polymorphisms that are associated with enhanced dopamine neurotransmission will be more neurally reward sensitive, score higher on self-reported impulsivity, and make riskier choices. In a sample of 85 participants, five genetic polymorphisms were genotyped and used to …

A Multilevel Examination Of Cultural Moderators Of The Job Demands-Resources Model, Seulki Jang

USF Tampa Graduate Theses and Dissertations

Although the Job Demands-Resources Model (JD-R) is the dominant theoretical framework used to understand the relationship between workplace factors and employee well-being, the cross-cultural generalizability of this model has seldom been directly tested. Therefore, this study examined whether and to what extent relationships between: 1) job demands (i.e., organizational constraints) and strain (i.e., job satisfaction, and turnover intentions) and 2) job resources (i.e., job control, participation in decision-making, direct supervisor support, senior leader support, and clear goals and performance feedback) and strain were moderated by cultural dimensions (i.e., individualism-collectivism and uncertainty avoidance). Survey data from workers in 28 countries were …

Genetic Moderation Of Phenotypic And Neural Indicators Of Peer Influenced Risk-Taking Behavior: An Experimental Investigation, Troy Alan Webber

USF Tampa Graduate Theses and Dissertations

Risk-taking behavior (RTB) is defined as behavior involving the probability of reward with concurrent probability of some negative outcome. Peer influence is among the most robust predictors of RTB, such that greater peer influence, particularly deviant or delinquent peer influence, is associated with increased RTB. Evidence suggests that those with genetic predispositions for RTB may also be more susceptible to peer influence as a function of genotype. Given that genetic polymorphisms within the dopaminergic system have evidenced associations with various forms of RTB and delinquent peer affiliation, it is possible that these genes may interact with peer influence to predict …

Personality As A Predictor Of Occupational Safety: Does It Really Matter?, Stephanie Anne Andel

USF Tampa Graduate Theses and Dissertations

Past research demonstrates the high prevalence of occupational accidents and injuries, and therefore much work has gone into examining potential antecedents to such incidences. However, while some research has examined personality as a potential antecedent, results suggesting personality as a significant predictor of occupational safety remain inconclusive. Therefore, the purpose of the current work is to conduct a cross-sectional multi-source survey study that will take a closer look at the relationships between various personality variables and occupational safety. Essentially, the purpose of the current study is threefold: (1) to examine the relationships between two Big Five personality factors, safety locus …

Interleaved Effects In Inductive Category Learning: The Role Of Memory Retention, Alex Mackendrick

USF Tampa Graduate Theses and Dissertations

Interleaved effects are widely documented. Research demonstrates that interleaved presentation orders, as opposed to blocked orders typically benefit inductive category learning. What drives interleaved effects is less straightforward. Interleaved presentations provide both the opportunity to compare and contrast between different types of category exemplars, which are temporally juxtaposed, and the opportunity to space study of the same type of category exemplars, which are temporally separated within the presentation span. Accordingly, interleaved effects might be driven by enhanced discrimination, enhanced memory retention, or both in some measure. Though recent studies have largely endorsed enhanced discrimination as the critical mechanism driving interleaved …

Hpv Vaccine Decision-Making Among Male Sexual Minorities: An Integrative Theoretical Framework For Vaccine Promotion, Christopher W. Wheldon

USF Tampa Graduate Theses and Dissertations

Men who have sex with men (MSM) are at increased risk of anal cancer as a result of anal HPV infection. Routine HPV vaccination is recommended for all MSM up through age 26; however, vaccine uptake among this population is low. The Integrative Model of Behavioral Prediction (IM) was used to identify, describe, and explain psychosocial factors related to HPV vaccine decision-making for young MSM. A sequential mixed-methods approach consisting of semi-structured interviews, a quantitative survey, and a qualitative open-ended survey was used to address the following aims: (1) Determine salient outcome, normative, efficacy, and control beliefs related to HPV-vaccination …

Editorial: Neural Implementation Of Expertise, Merim Bilalic, Robert Langner, Guillermo J. Campitelli, Luca Turella, Wolfgang Grodd

Research outputs 2014 to 2021

How the brain enables humans to reach an outstanding level of performance typical of expertise is of great interest to cognitive neuroscience, as demonstrated by the number and diversity of the articles in this Research Topic (RT). The RT presents a collection of 23 articles written by 80 authors on traditional expertise topics such as sport, board games, and music, but also on the expertise aspects of everyday skills, such as language and the perception of faces and objects. Just as the topics in the RT are diverse, so are the neuroimaging techniques employed and the article formats. Here we …

Emotion Regulation And Residual Depression Predict Psychosocial Functioning In Bipolar Disorder: Preliminary Study, Rodrigo Becerra, Kate Cruise, Craig Harms, Alfred Allan, Darryl Bassett, Sean Hood, Greg Murray

Research outputs 2014 to 2021

This study explores the predictive value of various clinical, neuropsychological, functional, and emotion regulation processes for recovery in Bipolar Disorder. Clinical and demographic information was collected for 27 euthymic or residually depressed BD participants. Seventy one percent of the sample reported some degree of impairment in psychosocial functioning. Both residual depression and problems with emotion regulation were identified as significant predictors of poor psychosocial functioning. In addition, to residual depression, the results of the current study introduce a variable of emotion dysregulation to account for poor psychosocial functioning among BD populations. Improving emotion regulation strategies, in particular, concentration and task …

Global Measures Of Gender Empowerment: A Case Study Of Sri Lankan Export Processing Zone (Epz) Workers, Peter Hancock, Sharon Middleton

Research outputs 2014 to 2021

This pape r focuses on global measures of gender empowerment released a n- nually by the UNDP and the World Economic Forum. It discusses and critiques these measures on a global level and juxtaposes this analysis against research conducted among women who work in Sri Lanka's Export Processing Zones (EPZs). Global measures of gender equality show that in Sri Lanka gender-based inequality is increasing, despite the nation dramatically improving its economy and poverty levels and meeting some of the Millennium Development Goals. To explain this contradiction, we sampled 2,304 women to explore how they experienced gender and empowerment and to …

Memory Behaviour Requires Knowledge Structures, Not Memory Stores, Guillermo J. Campitelli

Research outputs 2014 to 2021

Since the inception of cognitive psychology dominant theories of memory behavior have used the storage metaphor. In the multi-store models (e.g., Broadbent, 1958; Atkinson and Shiffrin, 1968; Baddeley and Hitch, 1974) the memory system comprises one or more short-term memory (STM) stores and a long-term memory (LTM) store. These stores are places where information is located for varying periods of time (i.e., seconds in the STM stores, and minutes to lifetime in the LTM store) and they have varying capacity limits: large for the LTM store, very limited for the STM store—4 to 7 items, see Miller (1956), Broadbent (1958), …

Exposure To Narratives And Social Reasoning, Cassandra Chlevin

Honors Theses

This study drew predominantly from previous work on the relationships of narrative and non-narrative texts with empathy and social reasoning. It has been posited that fiction -- due to the parallels between narrative texts and the social world -- may help readers maintain if not cultivate their social skills, whereas readers of non-narrative material may not have this benefit. This project attempted to both replicate and extend this pattern in a Seventh-day Adventist Christian sample by using instruments employed in previous research as well as a set of Bible-based instruments. Correlational analysis and nested linear regression were used to examine …

Narcissism And The Selfie: Investigating Millennial Narcissism On Instagram, Megan Reed

Honors Theses

Recent studies revealed a correlation between self-promoting images on social media and higher levels of narcissism. This research further examined the relationship between narcissism and use of social media by determining the proportion of selfies an individual posts on Instagram and narcissism among millennials. The proportion of pictures that were selfies was measured in two ways: in the subject's past 4-weeks of picture posting and in the last 30 pictures the subject posted. The standard Narcissistic Personality Inventory (NPI) was used to measure the subject's level of narcissism. Correlation analyses revealed that no correlations were found between the NPI score …

Methods: 33 HCV+ adults were evaluated two months before IFN initiation (baseline), three months into IFN, and six months following IFN termination (IFN+ Group). 31 HCV+ adults who did not undergo IFN therapy were evaluated at baseline and six months later (IFN− Group). At each evaluation, participants completed the Neuropsychological Assessment Battery (NAB) Attention, Memory and Executive Functions Modules, …

Is What Is Past Always Prologue? Priming To Past Conflicts And Fear Of Terrorism Influence Americans’ Support For Military Intervention In Syria, Daniel Walter Snook Ii

UNF Graduate Theses and Dissertations

Implicit knowledge influences decision-making in a variety of areas, including conflict resolution and decisions about war. Individuals may unknowingly apply implicit knowledge from past experiences to present experiences, even if that information leads to less accurate decisions in the present experience. The current study is an exploration into how implicit knowledge of past international conflicts and fear of terrorism affects recommendations for military conflict resolution in current international conflicts. Priming is one way to make implicit knowledge salient, and participants in this study were implicitly primed to think of either the Iraq War, World War II, or no war in …

A Model For Measuring The Contribution Of Form To Perception Of Biological Sex In Point-Light Actors, Michael Mintz

Dissertations and Theses @ UNI

People are able to judge the sex of actors represented in point-light displays. Much of the previous literature has focused on the contribution of motion information to this judgment, or has focused specifically on information gathered from the shoulders and hips. The purpose of the current study is to model how form information, based upon the distance between the dots representing a point-light actor’s key joints, the shoulder, hip, elbow, knee, wrist, and ankle points, contributes to the perception of biological sex. In a pilot study, 6 naïve observers responded to 63 computer generated stimuli that ranged from extremely female …

Different Levels Of Negative Emotions And Their Impact On Prosocial Behavior, Tsamchoe Dolma

Dissertations and Theses @ UNI

In this fast and competitive world, people are becoming less likely to help others. According to the Bureau of Labor Statistics (2014), the volunteerism rate reached the lowest point in 2013 since 2002. This decrease in prosocial behavior makes the study of prosocial behavior important, especially with the increasing numbers of charitable organizations and their competition to attract more donors and volunteers. Public service advertisements (PSA) are used as a common medium to garner help and support, and many of them use emotional appeals to enhance persuasion. The literature on persuasion shows that emotions have persuasive power to change people's …

Identification Of Sluggish Cognitive Tempo By Pre-Service Teachers, Rachel Elizabeth Meisinger

Dissertations and Theses @ UNI

Current research suggests that Sluggish Cognitive Tempo (SCT) is a distinct attentional disorder from Attention-Deficit/Hyperactivity Disorder (ADHD) that is characterized by a hypoactive, sluggish behavior pattern (Barkley, 2014). Further, unlike ADHD, SCT represents a more passive form of inattention that does not overly disrupt classroom learning goals. Thus children with SCT may be ‘falling through the cracks’ in schools. If children with SCT are going unrecognized in the classroom, they are likely not getting referred for treatment and additional educational services. SCT is related to many internalizing, academic, and social difficulties (Becker & Langberg, 2013, 2014) and early identification and …

The Influence Of The Single Stereotype On Moral Judgments, Peng Zhang

Dissertations and Theses @ UNI

Stereotypes can powerfully influence people’s moral judgments. For example, stereotypes of atheists lead people to report immoral behavior as more consistent for atheists than Christians (Wright & Nichols, 2014). When targets are labeled as “obese” or “hippie”, perceivers morally judge them more harshly than targets who are not assigned such labels (Masicampo, Barth, & Ambady, 2014). However, limited research has examined how stereotypes of single people can influence perceivers’ moral judgments. Because of various negative stereotypes people hold about single people (Conley & Collins, 2002; DePaulo & Morris, 2005), it was anticipated that people would morally judge a single target …

Do Depressive Symptoms Predict The Incidence Of Myocardial Infarction Independent Of Hopelessness?, Patrick Pössel, Amanda M. Mitchell, Kimmo Ronkainen, George A. Kaplan, Jussi Kauhanen, Maarit Valtonen

Faculty and Staff Scholarship

Depression and hopelessness predict myocardial infarction (MI), but it is unclear whether depression and hopelessness are independent predictors of MI incidents. Hopelessness, depression, and MI incidence rate 18 years later were measured in 2005 men. Cox regressions were conducted with hopelessness and depression serving as individual predictors of MI. Another Cox model examined whether the two predictors predict MI when adjusting for each other. Depression and hopelessness predicted MI in independent regressions but when adjusting for each other, hopelessness, but not depression, predicted MI incidents. Thus, these results suggest that depression and hopelessness are not independent predictors of MI.

Integrating Beck’S Cognitive Model And The Response Style Theory In An Adolescent Sample., Stephanie Winkeljohn Black, Patrick Pössel

Faculty and Staff Scholarship

Depression becomes more prevalent as individuals progress from childhood to adulthood. Thus, empirically supported and popular cognitive vulnerability theories to explain depression in adulthood have begun to be tested in younger age groups, particularly adolescence, a time of significant cognitive development. Beck’s cognitive theory and the response style theory are well known, empirically supported theories of depression. The current, two-wave longitudinal study (N = 462; mean age = 16.01 years; SD = 0.69; 63.9 % female) tested various proposed integrative models of Beck’s cognitive theory and the response style theory, as well as the original theories themselves, to determine if …

Injunctive And Descriptive Norms Effect On Physical Activity, Monica Lynn Ehn

Dissertations and Theses @ UNI

Nearly half of adults in the United States do not meet the recommended guidelines for both aerobic and strengthening activities despite the benefits of regular physical activity (National Center for Health Statistics, 2014; US Department of Health and Human Services, 2008). The purpose of the current study was to test whether normative feedback (i.e., descriptive and descriptive plus injunctive norms) affects levels of physical activity. Participants wore a Fitbit Zip pedometer to record exercise behavior and received normative feedback messages sent to their mobile phones. Participants were 52 undergraduate students with a mean age of 18.66 (SD = 0.83); 27 …

Influence Of Learner Factors On Soldier Attitude Toward Army Serious Gaming, Mitchell L. Bonnett

STEMPS Theses & Dissertations

This study determined the influence of the learner factors on Soldier attitudes toward the use of serious gaming for U.S. Army training and leader development. It extended Selwyn's work (Selwyn, 1997a, 1997b, 2003, 2004, 2006, 2013; Selwyn, Gorard, Furlong, & Madden, 2003) identifying or measuring attitude toward using a technology and Bonanno and Kommers (2008) work extending Selwyn's work to measure the influence of learner factors on those attitude components toward the use of Army serious gaming for instructional purposes. The population studied was 709 Active duty U.S. Army Soldiers.

This quantitative non-experimental descriptive research design methodology used a 21-item …

My Own Worst Enemy: Exploring Factors That Predict Self-Harm, Matthew Allen Loesch

UNF Graduate Theses and Dissertations

Current research on factors predicting self-harm focus on disparate factors and may not be able to comprehensively explain the mechanisms causing self-harm. The aim of the current study was to examine factors that may be related yet independently predict self-harm. Factors discussed include rumination, self-criticism, and working memory. A binary logistic regression found that the only factor that predicted the presence of self-harming behavior was a high level of self-criticism. Further, a Classification and Regression Tree found that the single strongest predictor of self-harming behavior was a belief that love needs to be continually earned from others. Our findings have …

The Relationship Between Illness Representations, Avoidant Coping, And Health Outcomes In People With Ongoing Symptoms Of Chronic Illness, Emily A. Bell

UNF Graduate Theses and Dissertations

Illness representations play an important role in the way people with chronic illness manage symptoms and view their overall health. Those suffering from functional somatic syndromes as well as conventional diagnoses seek information and meaning about their health threats in order to make appraisals concerning health outcomes. The primary interest of this study was to determine whether illness representations predict coping strategies which in turn influence general health outcomes. Data was collected from a series of four online surveys that measured an individual’s illness representations (IPQ-R), coping responses (Brief COPE), and health outcomes (RAND-36). The sample included 204 participants (169 …

The Role Of Neurotensin Receptors On Visceral Pain And Activity Levels In Mice., Christopher J. Walker

UNF Graduate Theses and Dissertations

This study examines the effects of neurotensin (NT) receptor sites on the sensation of visceral pain. Previous work by researchers has found, through the use of NT analogs, that visceral pain is closely associated with NT receptor 2 (NTSR2). This study tested 70 genetically modified mice. The mice were either missing NTSR1, NTSR2, or were wild-type (WT) mice that were not missing any NT receptors. The mice were injected intraperitoneally with either saline or acetic acid then observed for a 60 minute period and writhing behavior was recorded. Twenty four hours later activity levels were recorded in the open field …

Self-Monitoring And Romantic Relationships: Individual Differences In Romantic Jealousy, Tiffany Lucille Andolina

UNF Graduate Theses and Dissertations

To extend the research on self-monitoring and romantic relationships, we explored the connection between self-monitoring and romantic jealousy using a between-subjects design. We hypothesized high self-monitors (like men) would find sexual infidelity more distressing than emotional infidelity, whereas low self-monitors (like women) would find emotional infidelity more distressing than sexual infidelity. Participants completed the 25-item Self-Monitoring Scale (Snyder, 1974) and 6 hypothetical infidelity scenarios (Buss et al., 1999). To statistically control for third variables, participants also completed the 11-item Sociosexual Orientation Inventory (Gangestad & Simpson, 1991). Although we found a main effect for self-monitoring in romantic jealousy, these results did …

An Exploration Of The Wheel-Induced Feeding-Suppression, Stephen Benjamin Peckham

Theses and Dissertations (Comprehensive)

Anorexia nervosa is an enigmatic human condition typified by food-restriction that is often accompanied by extensive exercise. This has been modeled in rats in the wheel-induced feeding-suppression (WIFS) model. In this model, animals are given access to a running-wheel, which induces a volitional drop in food-consumption. Short periods of wheel access have induced a feeding-suppression which is effectively reversed by chlorpromazine administration (Adams et al., 2009). Recent attempts at replicating Adams et al.’s (2009) feeding-suppression have, however, been unsuccessful (Peckham et al., 2013). These attempts raised questions as to whether or not the existing methodology is most effective at suppressing …

Misinformation And Need For Cognition: How They Affect False Memories, Lilyeth Antonio

UNF Graduate Theses and Dissertations

The purpose of this study was to gain a better understanding of false memories and Need for Cognition (NFC). The relationship was examined using a typical misinformation paradigm where participants viewed a video clip which depicted a museum burglary and were later presented with an auditory narrative that contained misleading information about the video they previously saw. Half of the participants were exposed to warnings of misinformation. Additionally, the effect of question type (e.g., central, peripheral, and neutral) was taken into account. A main effect for NFC was found indicating that high NFC individuals had fewer false memories for the …

Family Stressors And Problem Behaviors Of At-Risk Elementary School Girls: A Latent Class Analysis, Cameron M. Perrine

UNF Graduate Theses and Dissertations

In order to obtain a closer look into the relationships between an at-risk populations’ family stressors and future school problem behaviors, a Latent Class Analysis (LCA) of family stressor variables was performed on at-risk elementary school girls from Health Zone 1. Participants were 308 girls with a mean age of 8.79 years. The dataset was inherited from the Delores Barr Weaver Policy Center and analyses were run to uncover latent classes of family stressors. Class membership was then utilized to predict future behavioral referrals and suspensions from school. A total of three classes emerged from the LCA: “Exposure to Trauma”; …
