The Role Of Valproic Acid, A Histone Deacetylase Inhibitor, In Reducing Anxiety Levels In Rats: An Epigenetics Study, Juliet Buteme

Honors College Theses

Rats, like humans, show personality traits: they are born with different anxiety levels (i.e., high (HAn) or low anxiety (LAn) levels). In this study, we investigated (1) if treatment with valproic acid (VPA) can lower anxiety level in trait anxiety rats and (2) how VPA may interact with environment (e.g., enriched (EE), standard (SE) and isolated environments (IE)). VPA is a deacetylase inhibitor that increases Histone 3 acetylation, a known epigenetic mechanism that interacts with stress response proteins, and treats epilepsy and mood disorders. Since rats reared in IE exhibit heightened anxiety levels as compared to those in EE, we …

An Examination Of Psychological Climate Linking Mechanisms Across The Strategic Priorities Of Health And Stress, Alec Munc

All Dissertations

Given that employee health and well-being represent a significant source of financial costs for organizations, this dissertation seeks to address some of the pathways through which organizational efforts to improve physical and mental health may operate. This study drew from a model of safety climate (Neal & Griffin, 2000) to propose that psychological climate exerts in influence on employee health and well-being through the joint moderators of knowledge/motivation and behaviors. The model also extended beyond the typical climate linking mechanisms to include moderators both individual (behavioral activation & behavioral inhibition systems) and contextual (workplace physical exposure). Using a two-wave prospective …

Role Of Recent And Remote Context Exposures On Incubation Of Fear Memories, Peter Zambetti

Psychology

Studying learning and memory through the methods of Pavlovian fear conditioning has been a topic of behavioral neuroscience research for decades. Anxiety disorders such as post-traumatic stress disorder can be modeled in rodents through fear conditioning. This study took on a different approach to study the learning and recall of a fear memory by using a within subjects group. This group was tested at both a recent and remote interval. The recent timepoint was three days after conditioning and the remote timepoint was thirty-one days after conditioning. The timepoints are used to observe the effect the passage of time has …

Executive Functioning Outcomes Among Self-Harming Adolescents Receiving Dbt-A, Alphonso A. Smith

Loma Linda University Electronic Theses, Dissertations & Projects

Changes in WM, GM, and neural activation in networks involving the PFC underlie the development of EFs during adolescence; however, adolescents with DSH have impaired EFs in the areas of inhibition, emotion regulation, shifting, and interpersonal functioning. DBT-A has been shown to be effective in treating these youth and the skills of mindfulness, emotion regulation, distress tolerance, interpersonal effectiveness, and “walking the middle path” are suited to treat their impaired EFs. As such, this study examined EF changes in adolescents receiving DBT-A and discussed implications for treatment and brain-behavior relationships. Ninety-three adolescents from a 16-week DBT-A program for DSH were …

Aesthetics And Performance Evaluation Of Post-Industrial Public Parks, Adel C. Vaughn

Landscape Architecture Undergraduate Honors Theses

Post-Industrial sites are often un-utilized and deserted places that are an aesthetic, social, ecological, and physical hindrance to the realm of the cities in which they lie, however they possess enormous potential. With respectful and transformative design, these new public parks gain a variety of benefits that extend well beyond the typical benefits exhibited by public parks due to their rich history, fascinating existing structures, high levels of visual and sensorial stimulation, one-of-a-kind traits, and opportunity for impactful change. By evaluating these post-industrial public parks, knowledge can be gained about what specific elements in the landscape contribute to their overall …

Community-Based Rehabilitation Supports For Social Inclusion And Work Participation Of Young Adults With Visual Impairment In Kenya: A Case Study, Philomena Jepkemboi Tanui

Graduate Theses and Dissertations

Young adults with a visual impairment (VI) experience less interaction with the community that impacts the way they relate to the world as they transition to the larger society where they face significant barriers of adjustment, exclusion, and work participation. Young adults with VI contend with cultural stigma, inequality, poor self-esteem caused by marginalization, a low quality of life (QOL), and lack of Social support systems that exist beyond the home. The aim of this study was to understand the perceptions of young adults with VI in Elgeyo-Marakwet and Kisumu Counties of Kenya concerning the barriers to community inclusion and …

Individual Differences In Anxiety Sensitivity And Emotional Avoidance: Potential Links In The Association Between Internalizing Problems And Peer Victimization, Juventino Hernandez Rodriguez

Graduate Theses and Dissertations

Chronic peer victimization has been linked to short- and long-term problems such as anxiety, depression, and aggression (Hawker & Bouton, 2000; Reijntjes, Kamphuis, Prinzie, & Telch, 2010; Reijntjes, Kamphuis, Prinzie, Boelen, van der Schoot, & Telch, 2011). Most children are able to escape the role of stable victim, but some struggle to end victimization and the negative trajectory associated with it. The present study explored individual differences in anxiety sensitivity and emotional avoidance, developmental vulnerabilities that heighten children’s risk for internalizing problems, as possible predictors of children’s level of peer victimization. Participants were 677 fourth-grade students and their teachers. Multi-informant …

Defining Treatment Response In Trichotillomania: A Signal Detection Analysis, David C. Houghton, Matthew R. Capriotti, Alessandro S. De Nadai, Scott N. Compton, Michael P. Twohig, Angela M. Neal-Barnett, Stephen M. Saunders, Martin E. Franklin, Douglas W. Woods

Psychology Faculty Research and Publications

The Massachusetts General Hospital Hairpulling Scale (MGH-HPS) and the NIMH Trichotillomania Severity Scale (NIMH-TSS) are two widely used measures of trichotillomania severity. Despite their popular use, currently no empirically-supported guidelines exist to determine the degrees of change on these scales that best indicate treatment response. Determination of such criteria could aid in clinical decision-making by defining clinically significant treatment response/recovery and producing accurate power analyses for use in clinical trials research. Adults with trichotillomania (N = 69) participated in a randomized controlled trial of psychotherapy and were assessed before and after treatment. Response status was measured via the Clinical …

Relationship Dealbreakers: Traits People Avoid In Potential Mates, Peter K. Jonason, Justin R. Garcia, Gregory D. Webster, Norman P. Li, Helen E. Fisher

Research Collection School of Social Sciences

Mate preference research has focused on traits people desire in partners (i.e., dealmakers) rather than what traits they avoid (i.e., dealbreakers), but mate preferences calibrate to both maximize benefits and minimize costs. Across six studies (N > 6,500), we identified and examined relationship dealbreakers, and how they function across relationship contexts. Dealbreakers were associated with undesirable personality traits; unhealthy lifestyles in sexual, romantic, and friendship contexts; and divergent mating strategies in sexual and romantic contexts. Dealbreakers were stronger in long-term (vs. short-term) relationship contexts, and stronger in women (vs. men) in short-term contexts. People with higher mate value reported more dealbreakers; …

Psychometric Properties Of The Centrality Of Pain Scale, Benjamin J. Morasco, Dennis C. Turk, Christina Nicolaidis

Regional Research Institute for Human Services

The Centrality of Pain Scale (COPS) is a recently developed patient-centered, 10-item self-report measure designed to assess how central, or dominating, in their lives individuals with chronic pain perceive pain to be. The COPS underwent initial development and validation previously; preliminary results suggested that the measure had excellent psychometric properties and that COPS scores were associated with important clinical factors. The purpose of the present study was to examine the psychometric properties of the COPS in a sample of individuals with mixed chronic pain diagnoses (N = 178) being treated at a U.S. Veterans Affairs Medical Center. Principal components analysis …

Meaning As A Buffer Against Adolescent Psychopathology, Ellen Shaina Dulaney

College of Science and Health Theses and Dissertations

This thesis investigates the function of meaning in life in adolescence to ascertain whether specific psychological resources may protect youths against threats to subjective well-being. Meaning in life and the search for the meaning in stressful occurrences were independently examined for their influence on stress impact and depression symptomatology. 201 American middle-school and high-school students between 12 and 19 years of age were recruited for this study. Participants reported on questionnaires targeting frequency of negative life events; depressive symptoms; sense of meaning; and tendency to reframe stressors in terms of their meaning, termed “stressor meaning seeking”. It was expected that …

Prospective Predictors Of Adolescent Bmi: Parenting Style, Gender, And Weight Perception, Trey V. Dellucci

College of Science and Health Theses and Dissertations

Obesity affects both adolescents and adults worldwide (Popkin & Doak, 1998). Determining which factors contribute to risk factors to the high prevalence of obesity in America is important because excess weight can negatively affect both physical health and psychosocial functioning (Kolotkin, Meter, & Williams, 2001). Few longitudinal studies have assessed the association between parenting styles and adolescent’s body mass index (BMI; Rhee et al, 2006). Past research has shown that parents greatly influence adolescent’s body image (Al Sabbah et al., 2009). Using data from the National Longitudinal Study of Adolescent Health, the current study examined the influence of parenting styles …

Intercultural Communication Between Forensic And Clinical Psychologists, Brittany Schmeck

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

While working in clinical and forensic psychology settings, a communication difficulty between the two professions became apparent. Forensic psychologists often appeared cold and callous from the clinical psychologist’s perspective, while clinical psychologists often appeared naïve or too client centered from the forensic psychologist’s perspective. I wondered if viewing each subfield of psychology as a culture could facilitate better communication through intercultural communication. Guided by Intercultural Communication in Contexts (Martin & Nakayama, 2010) in approaching intercultural communication between the two professions, I explored factors contributing to each profession’s cultural identities. Once this was established, I attempted to explore the different ways …

Word-Length Correlations And Memory In Large Texts: A Visibility Network Analysis, Lev Guzmán-Vargas, Bibiana Obregón-Quintana, Daniel Aguilar-Velázquez, Ricardo Hernández-Pérez, Larry S. Liebovitch

Publications and Research

We study the correlation properties of word lengths in large texts from 30 ebooks in the English language from the Gutenberg Project (www.gutenberg.org) using the natural visibility graph method (NVG). NVG converts a time series into a graph and then analyzes its graph properties. First, the original sequence of words is transformed into a sequence of values containing the length of each word, and then, it is integrated. Next, we apply the NVG to the integrated word-length series and construct the network. We show that the degree distribution of that network follows a power law, P(k)∼k−γP(k)∼k-γ, with two regimes, which …

Risk And Resiliency Factors At School Entry: Relations To Academic And Behavioral Outcomes In Early Adolescence, Krystle Kuzia Preece

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to examine how early academic and behavioral variables in kindergarten (i.e., academic performance, first time kindergarten status, early school-related emotional adaptation, prosocial behavior, externalizing behaviors, and internalizing behaviors) were related to academic and behavioral outcomes in eighth grade (i.e., academic performance, retention, suspension, externalizing behaviors, internalizing behaviors, and having an educational/mental health diagnosis). Archival data from the Early Childhood Longitudinal Study—Kindergarten Cohort (ECLS-K) database that included approximately 5,700 participants from across the U.S., were examined to answer three research questions: (1) How are early academic and behavioral variables related to each other among youth …

Engaging Overqualified Employees: The Role Of Job And Nonwork Crafting, Soner Dumani

USF Tampa Graduate Theses and Dissertations

The present study examined the relationship between perceived overqualification and work engagement through basic need satisfaction at work and further incorporated job crafting and nonwork crafting to understand the indirect role of need satisfaction. In study 1, a new measure for targeted nonwork crafting was developed and validated. The final scale provided adequate reliability and validity evidence, and predicted life satisfaction and job satisfaction above and beyond the measures of intrinsic motivation and recovery experiences. The main study included a total of 321 full-time employees who had been working in their current job for at least 3 months and represented …

Adolescent Females With High-Functioning Asd: Self And Mothers’ Perspectives Of Their School And Social Experiences, Lindsey Land

USF Tampa Graduate Theses and Dissertations

Although the prevalence of Autism Spectrum Disorder (ASD) is currently 1 in 68 (Centers for Disease Control, 2015) and research in this area is growing, high-functioning individuals on the spectrum are often overlooked. This is because of their relatively milder symptoms. The recent collapse of Asperger Syndrome (AS) with autism in the most recent version of the Diagnostic and Statistical Manual (DSM-5; APA, 2013) also has obscured the differences that may exist between those with higher vs. lower levels of functioning. Among youth with High-Functioning Autism Spectrum Disorder (HFASD), girls are a particularly understudied and potentially vulnerable group. Previous research …

Factors Influencing The Impact Of Aggressive And Violent Media On Children And Adolescents, Ashlee M. Wiedeman, Jacqueline A. Black, Autumn L. Dolle, Emmanuel J. Finney, Kendell L. Coker

Psychology Faculty Publications

The influence of aggressive and violent media on children and adolescents has been a topic of concern for several decades. Research on this topic has suggested that both short term and long term exposure to aggressive/violent media can negatively impact this population. The purpose of this literature review is to discuss relevant research on the topic and examine various factors that may impact the risk of being influenced by this type of media. These factors can include time spent viewing media, content of the media viewed, gender, age, psychological characteristics, family, and peers. Various theoretical approaches to explaining the influence …

Parent-Child Math Anxiety And Math-Gender Stereotypes Predict Adolescents' Math Education Outcomes, J. Casad

Psychology Faculty Works

Two studies examined social determinants of adolescents' math anxiety including parents' own math anxiety and children's endorsement of math-gender stereotypes. In Study 1, parent-child dyads were surveyed and the interaction between parent and child math anxiety was examined, with an eye to same- and other-gender dyads. Results indicate that parent's math anxiety interacts with daughters' and sons' anxiety to predict math self-efficacy, GPA, behavioral intentions, math attitudes, and math devaluing. Parents with lower math anxiety showed a positive relationship to children's math outcomes when children also had lower anxiety. The strongest relationships were found with same-gender dyads, particularly Mother-Daughter dyads. …

Promoting Public Health In The Context Of The “Obesity Epidemic”: False Starts And Promising New Directions, T. Mann, A. J. Tomiyama, Andrew Ward

Psychology Faculty Works

In the battle to combat obesity rates in the United States, several misconceptions have dominated policy initiatives. We address those misconceptions, including the notion that restrictive diets lead to long-term weight loss, that stigmatizing obesity is an effective strategy for promoting weight reduction, and that weight and physical health should be considered synonymous with one another. In offering correctives to each of these points, we draw on psychological science to suggest new policies that could be enacted at both the local and national levels. Instead of policies that rely solely on individual willpower, which is susceptible to failure, we recommend …

Perceptions Of Tornadoes, Tornado Warnings, Safety Actions, And Risk: Effects On Warning Response Among Undergraduates In Nebraska, Sabrina T. Jauernic

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Few studies show how university students perceive and respond to tornado warnings, or how they gain tornado-related knowledge. Lacking in the literature are investigations of how perceptions of tornado risk may influence actions. Using two separate surveys and two large samples of undergraduates enrolled in the University of Nebraska, the author determined significant relationships between student demographics, perceptions, and response actions. Incorrect perceptions were found, such as overpasses and southwest corners of buildings being safe, and cities being invulnerable to tornadoes. International students, especially, assumed cities were safe from tornadoes. Students had a tendency to confirm their risk instead of …

Individual, Family, And Culture Level Contributions To Child Physical Abuse And Neglect: A Longitudinal Study In Nine Countries, Jennifer E. Lansford, Jennifer Godwin, Liliana Maria Uribe Tirado, Arnaldo Zelli, Suha M. Al-Hassan, Dario Bacchini, Anna Silvia Bombi, Marc H. Bornstein, Lei Chang, Kirby Deater-Deckard, Laura Di Giunta, Kenneth A. Dodge, Patrick S. Malone, Paul Oburu, Concetta Pastorelli, Ann T. Skinner, Emma Sorbring, Sombat Tapanya, Liane Peña Alampay

Psychology Department Faculty Publications

This study advances understanding of predictors of child abuse and neglect at multiple levels of influence. Mothers, fathers, and children (N = 1,432 families, M age of children = 8.29 years) were interviewed annually in three waves in 13 cultural groups in nine countries (China, Colombia, Italy, Jordan, Kenya, Philippines, Sweden, Thailand, and the United States). Multilevel models were estimated to examine predictors of (a) within-family differences across the three time points, (b) between-family within-culture differences, and (c) between-cultural group differences in mothers’ and fathers’ reports of corporal punishment and children’s reports of their parents’ neglect. These analyses addressed …

Handedness For Unimanual Grasping In 564 Great Apes: The Effect On Grip Morphology And A Comparison With Hand Use For A Bimanual Coordinated Task, A. Meguerditchian, Kimberley A. Phillips, A. Chapelain, L. M. Mahovetz, S. Milne, T. Stoinski, A. Bania, E. V. Lonsdorf, J. Schaeffer, J. Russell, William D. Hopkins

Psychology Faculty Research

A number of factors have been proposed to influence within and between species variation in handedness in non-human primates. In the initial study, we assessed the influence of grip morphology on hand use for simple reaching in a sample of 564 great apes including 49 orangutans Pongo pygmaeus, 66 gorillas Gorilla gorilla, 354 chimpanzees Pan troglodytes and 95 bonobos Pan paniscus. Overall, we found a significant right hand bias for reaching. We also found a significant effect of the grip morphology of hand use. Grasping with the thumb and index finger was more prevalent in the right …

A How-To Guide To Single-Parent Ministry: An Inside Look To The Single Parent World In The Christian Community, John E. Walker Ii

Senior Honors Theses

The status of the family dynamic in the church has changed significantly, but the cultural understanding of ministers regarding the dynamic has changed little to none. As a result, the church’s ministry has become ineffective to the single-parent community because of ignorance. The goal of this thesis is to help educate Christian ministers and lay staff on the single-parent family condition and ministry opportunities to serve this demographic. This proposition includes information gained from interviews of single-parents, and ministers with experience regarding single-parents by someone with a single-parent upbringing. Overall, the single-parents interviewed stated that the Christian church is missing …

Improved Cardiorespiratory Fitness Is Associated With Increased Cortical Thickness In Mild Cognitive Impairment, Katherine Reiter, Kristy A. Nielson, Theresa J. Smith, Lauren R. Weiss, Alfonso J. Alfini, J. C. Smith

Psychology Faculty Research and Publications

Cortical atrophy is a biomarker of Alzheimer’s disease (AD) that correlates with clinical symptoms. This study examined changes in cortical thickness from before to after an exercise intervention in mild cognitive impairment (MCI) and healthy elders. Thirty physically inactive older adults (14 MCI, 16 healthy controls) underwent MRI before and after participating in a 12-week moderate intensity walking intervention. Participants were between the ages of 61 and 88. Change in cardiorespiratory fitness was assessed using residualized scores of the peak rate of oxygen consumption (V̇O_2peak) from pre- to post-intervention. Structural magnetic resonance images were processed using FreeSurfer v5.1.0. …

Sweet Love: The Effects Of Sweet Taste Experience On Romantic Perceptions, Ren Dongning, Kenneth Tan, Ximena B. Arriaga, Kai Qin Chan

Research Collection School of Social Sciences

Terms of endearment such as sweetie, honey, and sugar are commonly used in the context of describing romantic partners. This article explores how a relatively subtle manipulation, namely taste sensations, might influence romantic perceptions of a nonestablished relationship. Consistent with predictions, results from Studies 1 and 2 (n = 280) showed that participants evaluated a hypothetical relationship, but not an existing relationship, more favorably when exposed to sweet taste compared to non-sweet taste control. Study 3 (n = 142) further showed that participants indicated greater interest in initiating a relationship with a potential partner when exposed to sweet taste, as …

Butterfly Eyespots: Their Potential Influence On Aesthetic Preferences And Conservation Attitudes, Zoi Manesi, Paul A. M. Van Lange, Thomas V. Pollet

Research Collection School of Social Sciences

Research has shown that the mere presence of stimuli that resemble eyes is sufficient to attract attention, elicit aesthetic responses, and can even enhance prosocial behavior. However, it is less clear whether eye-like stimuli could also be used as a tool for nature conservation. Several animal species, including butterflies, develop eye-like markings that are known as eyespots. In the present research, we explored whether the mere display of eyespots on butterfly wings can enhance: (a) liking for a butterfly species, and (b) attitudes and behaviors towards conservation of a butterfly species. Four online experimental studies, involving 613 participants, demonstrated that …

Predicting Subjective Well-Being Using Social Support And Mindfulness For United Arab Emirates University Students, Sarah El Nabulsi

Theses

This thesis is concerned with assessing the psychological well-being of the United Arab Emirates University students’ community and predicting the integral factors that significantly contribute to it. Existing studies have explored pathologies such as depression and anxiety in an attempt to deduce knowledge indispensable to clinical interventions. This study deals with what the individuals with high psychological well-being are doing well and takes this knowledge to inform clinical interventions. In this context, it is noteworthy to argue that this thesis is one of the pioneering studies involving a predominantly local population, which allows for more successful and more culturally sensitive …

Getting Ahead: Socio-Economic Mobility, Perceptions Of Opportunity For Socio-Economic Mobility, And Attitudes Towards Public Assistance In The United States, Alissa Klein

USF Tampa Graduate Theses and Dissertations

In this research I first examine how Americans’ perceptions of what it takes to get ahead are influenced by their income and then compare those perceptions to measured levels of intergenerational socio-economic mobility. By better understanding these relationships I hope to gain insight into the paths people see to upward mobility, how this varies by income, and to what extent this belief is reflected in past mobility measurements. Additionally, I compare perceptions of what it takes to get ahead with responses regarding attitudes towards public assistance. The results of such a comparison could have important implications for public policy.

The Corpus Callosum In Primates: Processing Speed Of Axons And The Evolution Of Hemispheric Asymmetry, Kimberley A. Phillips, Cheryl D. Stimpson, J. B. Smaers, Mary Ann Raghanti, B. Jacobs, A. Popratiloff, Patrick R. Hof, Chet C. Sherwood

Psychology Faculty Research

Interhemispheric communication may be constrained as brain size increases because of transmission delays in action potentials over the length of axons. Although one might expect larger brains to have progressively thicker axons to compensate, spatial packing is a limiting factor. Axon size distributions within the primate corpus callosum (CC) may provide insights into how these demands affect conduction velocity. We used electron microscopy to explore phylogenetic variation in myelinated axon density and diameter of the CC from 14 different anthropoid primate species, including humans. The majority of axons were less than 1 µm in diameter across all species, indicating that …
