Psychology Faculty Publications

---

Background: Cardiovascular disease (CVD) is the leading cause of mortality and disability worldwide. While sex differences in CVD have been well documented, the physiological mechanisms of those sex differences remain unclear. As important components of the cardiovascular system, cardiac vagal control and baroreflex serve as mechanisms of sex differences in CVD and are modifiable factors for gender-specific CVD preventions. Methods: Ninety-four healthy adults (18–44 years of age; M_age = 21.09 years; 46 female) were recruited to complete the assessments of heart rate variability (HRV) at a resting baseline and the cardiac timing effect on an R-wave-locked reaction time (RT) …

Clostridioides Difficile: Identification Of Rival Organisms & Evaluation Of Non-Antibiotic Treatment Implementation, Justin Davis

Honors Undergraduate Theses

---

Clostrioides difficile is a common cause of nosocomial (hospital-acquired) infections. Patients receiving antibiotic treatment experience dysbiosis of gut microbiota, and C. difficile, normally held in check by the various other organisms, takes this opportunity to propagate. Symptoms of infection generally include diarrhea, colitis, dehydration, and fever. Understanding that C. difficile generally only causes illness when it is the dominant bacterium (i.e. when growth is relatively unchecked by other microbes), it is appropriate to investigate potential competitive organisms that may be introduced after antibiotic courses or during active C. difficile infection to effectively displace it. Fecal samples from the University …

How Hormonal Contraceptives Influence Injury In Female Athletes: A Systematic Review, Ashley V. Malvita

Honors Undergraduate Theses

---

Research indicates that female athletes have a higher risk of musculoskeletal injuries. Hormone fluctuations throughout the different periods of the menstruation cycle impacts the risk of injuries for women. Contraceptive use, most used in the form of an oral contraceptive pill, directly effects hormones and menstrual cycle related symptoms, with evidence of ameliorating some symptoms. Oral contraceptive use is suggested to influence musculoskeletal injuries in female athletes. However, there is little research and data that explores the direct relationship between oral contraceptive use and the injury rates of female athletes. Within this systematic review, five articles investigating this relationship fulfilled …

Neural Hyperactivity During Value-Based Decision-Making In People With Daily/Near Daily Cannabis Use, Miranda Ramirez

Theses and Dissertations--Psychology

---

Value-based decision-making involves the coordinated effort of multiple brain regions to guide future choices based on past experiences. These processes are disrupted in cannabis use disorder, where individuals continue to use cannabis despite negative consequences. Reinforcement learning (RL) paradigms can be used to capture changes in the value of available options and may inform how the brain is impacted by frequent cannabis use. This study combined fMRI with behavioral modeling of probabilistic choice task data to compare value-based choices between young adults reporting daily/near daily cannabis use (CAN) and controls (CTRL). Participants selected one of two options reinforced ($0.25) at …

Extracellular Free Water As An Imaging Biomarker Of Neuroinflammation, Cristina N. Pinheiro

Theses and Dissertations--Psychology

---

Older adults experience a chronic state of heightened immune response referred to as “inflammaging” which can be observed by detecting levels of proinflammatory cytokines in blood serum. These proinflammatory cytokines are secreted in the central nervous system and may also enter the brain through the blood brain barrier. Previous literature has suggested that extracellular free water, a magnetic resonance imaging metric, may allow us to detect alterations in the extracellular space which are thought to correlate with inflammation in the central nervous system. This study examined the correlation between two proinflammatory cytokines, IL-6 and TNFα, collected longitudinally and cross-sectionally imaged …

Establishing The Feasibility Of Crowdsourcing To Study Value-Based Decision-Making In Substance Use Disorders, Thomas Shellenberg

Theses and Dissertations--Psychology

---

Substance use disorders (SUDs) are characterized by repeated choices to use drugs despite adverse consequences. Value-based decision-making theory posits that choices are guided by predicted values of available options which are updated based on outcomes. Computational modeling of reinforcement learning (RL) during choice tasks has shown promise for uncovering latent mechanisms of decision-making. Recruiting people with SUD is difficult, but crowdsourcing offers an alternative for accelerating data collection. However, the validity of computational modeling using online choice task data has not been well-established. This thesis aimed to use the online crowdsourcing platform Prolific to 1) compare online and in-person choice …
