Advances in statistical techniques for analyzing biological data have driven the need for larger sample sizes, which are ultimately made possible through team science efforts. Findings from these efforts have led to a significant shift in approaches to biological data collection over the past decade, from traditional approaches relying on single measures or assays collected by individual investigators in small lab-based studies to high-dimensional methodologies embedded within large cohorts or multi-site studies. These recent large scale consortium efforts necessitate careful consideration across the full data pipeline, from pre-data generation and sample collection to processing and statistical analysis, while addressing challenges …

Daily Rhythms In Psychosocial Stress, Sleep, And Mood: A Multimethod Approach To Transdiagnostic Psychopathology Risk And Intervention, Gabriel Gilmore

Theses and Dissertations--Psychology

Rhythms are central to nearly every core physiological and psychological process and have profound influences on overall health and well-being, particularly in the context of mood disorders. This dissertation emphasizes a rhythm-centered framework for understanding transdiagnostic psychopathology, proposing that the temporal organization of psychosocial stress, sleep, and mood provides crucial information for the development and treatment of mood disorder symptomology. Current literature relies primarily on mean symptom levels, overlooking day-to-day patterns in psychosocial experiences. To address this key methodological gap, three studies are examined. Study 1 develops and validates the Psychosocial Stress Regularity Measure (PSRM), a brief single-item measure of …

The Relationship Between Estradiol And Progesterone Concentration Levels, Alcohol Consumption, And Inhibitory Control, Layne Elizabeth Robinson B.S.

Theses and Dissertations--Psychology

Alcohol use is increasing among women, with estimates for binge drinking having risen to levels similar to those seen in men. Despite this trend, sex differences regarding mechanisms of alcohol consumption have seldom been investigated. Our group and others have found evidence to suggest that ovarian sex hormones are associated with alcohol consumption and mechanisms that might be related to alcohol consumption, such as executive function deficits. The current study sought to extend this prior research in a larger sample with higher drinking rates and more rigorous methods, and to explore inhibitory control associations with drinking. Across the two samples …

Joint Associations Of Meditation And Physical Activity With Depression And Anxiety Symptoms In Us Adults: Nhis 2022, Yubing Wang

Human Movement Studies & Special Education Faculty Publications

Objectives

Physical activity and meditation may each relate to mental health, but their joint associations in U.S. adults are unclear. We examined the separate and joint associations of any past-year meditation and meeting physical activity (PA) guidelines with depression and anxiety symptoms.

Method

We analyzed data from the 2022 National Health Interview Survey Sample Adult file (n = 24,927). Exposures were meeting PA guidelines, any past-year meditation, and their four-level combination (Neither, PA only, Meditation only, Both). Outcomes were moderate-to-severe depressive and anxiety symptoms (PHQ-8/GAD-7 >= 10). Survey-weighted modified Poisson models estimated prevalence ratios (PRs), with interaction, sensitivity, and post …

Chronic psychosocial stressors contribute to cardiovascular disease (CVD) and related risk factors, particularly in under-resourced communities. Psychosocial stressors activate the hypothalamic-pituitary-adrenal (HPA) axis, leading to sustained cortisol action on immune cells. Natural killer (NK) cells are altered in distribution and function in cardio-metabolic diseases; however, pathways linking cortisol as a marker of chronic stress to NK cell dysfunction remain understudied. We recruited 186 African American women from the Step It Up Community-Engaged, Digital Health Physical Activity Intervention study and collected cortisol, NK cell measures, and psychosocial stress measures using validated questionnaires, including chronic stress and loneliness. Plasma cortisol levels were …

Effects Of Pressure-Based Virtual Reality Training On Mental Toughness In Athletes, Rylee J. Aspinwall

UNF Graduate Theses and Dissertations

Athletes often underperform in high-pressure situations due to challenges in emotional regulation rather than deficits in physical skill. Mental toughness, broadly defined as the ability to maintain performance under stress, is a key determinant of athletic success but remains difficult to train using traditional methods. Virtual reality (VR) offers a controlled and immersive environment for simulating competitive pressure; however, its application for training mental toughness remains limited. The present study examined the effects of pressure-based VR training on psychological and physiological responses in collegiate baseball and softball athletes. Participants completed up to eight VR training sessions under either high-pressure or …

Dispositional Mindfulness And Autonomic Reactivity, Thomas Dylan Boyer

Graduate Theses, Dissertations, and Problem Reports (ETD)

To explain how different facets of mindfulness were associated with task performance in distinctive ways, Lindsay and Creswell (2017) proposed the Monitor and Acceptance Theory (MAT). According to this model, the mindfulness facet of monitoring present state awareness was thought to influence task performance differently than the nonjudgmental acceptance facet of mindfulness, but no studies to date have examined this model with respect to an individual's physiological response to stressful tasks. Because dispositional mindfulness has been associated with both increased and decreased physiological and affective reactions to stress in previous studies, the present study tested whether the Monitoring facet of …

Heat Waves And Heart Rates: Exploring The Correlation Between Temperature And Anxiety, Denise Lori Loewinger, Laci Joy Walmer

Student Scholar Symposium

“Will an individual be more prone to anxiety or panic attacks with an increase in body temperature?” Anxiety is defined as a feeling of worry, nervousness, or unease, typically about an imminent event or something with an uncertain outcome. Commonly known is the idea that situational factors, such as the death of a family member or financial stress may increase a person’s anxiety levels. Yet, according to research, factors such as physical location or high temperatures may also determine the prominence of anxiety. Using temperature- controlled environments in conjunction with medical instruments, we measured the anxiety levels of participants through …

Examining The Relationship Between Gambling Advertising & Gambling Behavior, Ilkim Green, Eric Wickenhauser, Hannah White Ph.D

Undergraduate Research Symposium

Gambling advertising has become increasingly prevalent across various media platforms such as TV, social media, real-life advertising, etc. With advertisements designed to influence attitudes, intentions, and behaviors of potential and existing consumers, this review aims to compile existing research to examine the measurable effects of gambling advertising. Studies indicate that young people and problem gamblers are especially vulnerable to these advertisements, which normalize gambling and contribute to increases in gambling behavior. This effect on behavior is dose-dependent; increased exposure to advertising is associated with greater gambling engagement. While responsible gambling messages are often included in advertisements, they remain largely ineffective …

Neurobehavioral Mechanisms Of Psychotic-Like Experiences And Cannabis Use, Ethan Campbell

Psychology ETDs

As cannabis use has increased steadily over the past decade, there is critical need to evaluate early cannabis use as a potential risk factor for the development of psychosis. Neurobehavioral mechanisms underlying novelty salience could clarify how cannabis exposure may influence subclinical psychotic-like experiences (PLEs). The present study leveraged dynamic functional connectivity and task-fMRI to assess the role of novelty processing in cannabis use and PLEs. A group of brain regions dynamically tied to the salience network while viewing short films were found to increase their activation as a function of stimulus novelty during a novelty bandit task. PLEs were …

The Timing Of Pubertal Onset Affects Adults Anxiety Behavior In A Sex-Specific Manner, Evan Raubenolt

Honors Projects

This study aims to look at the relationship between the timing of pubertal onset and its long-term effects on adult anxiety behavior in rats. Though the topic of pubertal onset has been frequently discussed in developmental research, its exact effects have been inconsistent. Human models have shown that early and late maturing males are associated with a notable increase in adult anxiety behavior, while in rat models, similar sex-specific effects regarding anxiety have been demonstrated, though those studies focus on a causal relationship between exposure to stress and age of pubertal onset. This study first aims to examine that relationship …

Physiological Response To Concealed Information In A Mock-Crime Paradigm​, Ezra Koenigsberg, Tamya Mchenry, Jasmine Manzana, Taylor Powell, Samantha Jackson

Science University Research Symposium (SURS)

The Concealed Information Test (CIT), based on Lykken’s guilty knowledge framework, measures physiological responses when individuals recognize crime-related details compared to neutral alternatives. Previous studies show that variations in stimulus presentation enhance the CIT’s accuracy, especially through changes in electrodermal activity and heart rate. However, few studies have tested whether a Qualtrics-based mock-crime version of the CIT can replicate these physiological patterns. This study addresses that gap by adapting the CIT for a digital research environment. The goal is to determine whether participants show greater physiological arousal—measured through skin conductance, heart rate, and respiration—when exposed to crime-related “critical” stimuli compared …

The Potential Co-Occurrence Of Perfectionism, Food Insecurity, And Gpa With Orthorexia Nervosa Risk, Samantha Kay Gould

Master's Theses

There are indeterminate risk, prevalence, and correlation data on orthorexia nervosa (ON) as shown by current literature on disordered eating (Rodgers et al., 2021). As a roughly defined disordered eating pattern, ON may be better understood after identifying associations among other attributes in a college student sample (Abdullah et al., 2020; Mavrandrea & Gonidakis, 2023; Parra-Fernández, 2019; Rogowska et al., 2021). A cooccurrence and influence of perfectionism, food insecurity, and grade point average (GPA) with ON risk was hypothesized since current literature suggests college students exhibit each of these characteristics independently (Abdullah et al., 2020; Ambwani et al., 2019; Caferoglu …

Investigating The Relationship Between Noun Classes And Plant Folk Taxonomy In Chasu Language Of Kilimanjaro Region In Tanzania, Peter Rabson Mziray

Journal of Humanities and Social Sciences

The current study investigates the relationship between noun classes and plant folk taxonomy in Chasu (G 22). The study focuses on two objectives: the first objective is to describe the plant folk taxonomy in Chasu and the second objective is to determine the relationship between noun classes and plant folk taxonomy in Chasu. Data were collected from rural villages in Same and Mwanga districts by using free listing, field interviews (jungle-walk-and-identify), and written texts containing Chasu plant names. The findings reveal that Chasu folk taxonomy reflects different ethnobotanical categories; including a unique beginner which is mmea/mimea ‘plant(s)’, and three life …

Methylation Of The Dat1 Dopamine Transporter Gene In Combat Sport Athletes: Associations With Impulsivity And Reward Sensitivity, Milena Lachowicz, Remigiusz Recław, Aleksandra Suchanecka, Krzysztof Chmielowiec, Elżbieta Grzywacz, Jolanta Chmielowiec, Kinga Łosińska, Anna Grzywacz

Baltic Journal of Health and Physical Activity

Epigenetic mechanisms, such as DNA methylation, modulate behavioral traits, including impulsivity and reward sensitivity. The dopamine transporter gene (DAT1) plays a key role in dopaminergic function and is associated with self-regulation, attention, and the trait of addiction. This study summarized the DAT1 methylation status in patients practicing combat sports and its association with impulsivity, ADHD symptoms, and consequence sensitivity. One hundred control subjects were recruited using the Barratt Impulsivity Scale (BIS), the ADHD scale, and the Opportunity Response Scale. DAT1 methylation was measured using the bisulfite ionization method. A correlation analysis was performed with the comparison group. Athletes …

Neonatal Striatal Volume Is Associated With Infant Anhedonia, Melissa Nevarez-Brewster, Catherine H. Demers, Jessica L. Irwin, Laura M. Glynn, Martin A. Styner, Mercedes Hoeflich Haase, M. Camille Hoffman, Diego A. Pizzagalli, Benjamin L. Hankin, Elysia Poggi Davis

Psychology: Faculty Scholarship

Anhedonia is increasingly recognized as a transdiagnostic risk factor for psychopathology. New evidence demonstrates that anhedonia is present in infancy and early childhood. Structural variability in striatal regions involved in reward processing and pleasure seeking is concurrently linked to anhedonia, yet few studies have examined whether striatal differences presage anhedonia, and none have examined prospective associations before middle childhood. The present study examined whether neuroanatomical markers that confer risk for anhedonia can be detected as early as the neonatal period. Specifically, we tested whether the volume of striatal regions in neonates predicted the emergence of infant anhedonic behaviors at six …

Dermatoglyphic Fluctuating Asymmetry In Schizotypy, Marcus R. Thomas

All-Inclusive List of Electronic Theses and Dissertations

Schizotypy has been linked with many of the proposed endophenotypes of schizophrenia, but research is limited on the relationship between schizotypy and dermatoglyphic fluctuating asymmetry. The present study sought to examine relationships between schizotypy, dermatoglyphic fluctuating asymmetry, handedness, and season of birth. 146 undergraduate students were identified as schizotypes (n = 52) or controls (n = 94) based on the Multidimensional Schizotypy Scale and had their finger and palm prints collected along with completing additional measures of schizotypy and handedness. Schizotypes did not exhibit a greater degree of dermatoglyphic fluctuating asymmetry, negative schizotypy was associated with increased absolute finger ridge …

Two Essays On The Role Of Anthropomorphism In Consumer Behavior, Faegheh (Faa) Taheran

Theses and Dissertations in Business Administration

The first essay of this dissertation investigates the contradictory findings on the relationship between anthropomorphism and self-control by focusing on how everyday anthropomorphized objects, rather than the products being used for consumption, influence consumer behavior. While previous studies have shown that using anthropomorphized products may decrease consumers’ self-control, this paper examines how unrelated [to consumption] anthropomorphized objects in a consumer’s environment—such as a water bottle with a humanlike face—can evoke a sense of social presence, increasing consumers’ perceptions that they are being negatively evaluated. Drawing on mind perception theory, I propose that this fear of negative evaluation can enhance self-control. …

Electrophysiological Markers Of Emotion Dysregulation In Autistic Youth, Rachel G. Mcdonald

Theses, Dissertations and Culminating Projects

Emotion dysregulation (ED) is a transdiagnostic mechanism that is conceptualized as difficultly regulating emotions and deploying appropriate regulation strategies in response to environmental stimuli. Meta-analyses suggest that autistic people, across the lifespan, experience more severe ED as compared to both neurotypical people and those with mental health conditions. Despite elevated risk and evidence linking ED to disruptions in neural mechanisms, no studies to date have examined neural markers of ED in autistic populations. The current project uses multi-method and multi-informant measurement to examine similarities and differences in neural mechanisms of ED in autistic and non-autistic populations. Forty-four youth aged 11—17 …
