Exploring The Relationship Between Loneliness And Real-Time Measurements Of Gsr And Hrv During Concept Mapping, And Cortisol And Oxytocin Levels, Jangwon Seo

Masters Theses

This study attempts to explore loneliness among college students from a bio-physio-psycho-social perspective, and it utilizes real-time physiological measurements (GSR and HRV) and biomarkers (cortisol and oxytocin) in conjunction with psychosocial assessments. The study employs both qualitative and quantitative methods, which involve concept mapping exercises, with the aim of comprehending the full nature of how loneliness interacts with physiological and psychological processes. At Time 1 (T1) we found significant positive correlations between loneliness and elevated GSR levels, which is indicative of increased sympathetic arousal (r = .35, p < .01). Additionally, there were significant negative correlations between loneliness and mean RR intervals in HRV that indicated autonomic dysregulation featured by increased sympathetic activities as well as reduced parasympathetic functions (r = -.28, p < .05). However, at Time 2 (T2), these correlations were not significant indicating possible temporal fluctuations due to adaptive responses or extraneous variables such social support systems or coping mechanisms. The qualitative data from concept mapping enriched the analysis by providing deeper insights into the cognitive and emotional processes underlying loneliness. Despite limitations like demographic skewness, funding constraints, logistical challenges, etc., this, therefore, highlights the need for multidimensional investigations of psychological phenomena. This has implications for future research as well as clinical practice, which could include using these integrative measures to develop holistic interventions for mental health disorders.

Faculty Publications

Conservation of private lands is essential for protecting open space, supporting ecosystems and species, preserving resources, and facilitating outdoor recreation. One tool for private land conservation is a conservation easement – a voluntary legal agreement where a landowner surrenders certain rights to use or develop their property. This study explores landowner perceptions of perpetual conservation easements in areas of high conservation value in Missouri, focusing on landowners without existing easements. Through interviews, four themes emerge containing both motivations and constraints: prior knowledge, land protection, regulations, and finance. Many landowners were unfamiliar with conservation easements or had misconceptions or misunderstandings. The …

Mindreading And Embodiment: Beyond Mirror Neurons., Sanad Al Khatib

College of Arts & Sciences Senior Theses

This paper examines the question: how do we figure out what other people are thinking and why they act as they do, or put differently, how is it that we can read minds in daily life? For decades, the dominant view held that we explain and predict other people’s behavior by attributing to them mental states such as beliefs, desires, and intentions, represented symbolically in the brain. The embodied simulation model challenges this view, proposing that understanding others primarily relies on mirror neurons that activate both when we perform an action and when we observe someone else performing it. This …

Examing Fear Conditioning/Extinction And The Role Of The Amygdala In Human Neuroimaging., Olivia Cook

Electronic Theses and Dissertations

Fear plays a crucial role in survival but can lead to psychological disorders when dysregulated. Fears can be innate due to evolutionary relevance or learned through associative processes, where predictive accuracy of threat is pivotal. Disruptions in fear neurocircuitry contribute to anxiety disorders, characterized by heightened activation and impaired learning. Fear conditioning and extinction paradigms based on classical Pavlovian conditioning have been used to study mechanisms underlying fear learning. Using this experimental model, fear networks in rodents have been described in detail with clear distinction between conditioning and extinction neural functioning. Yet, there is no consensus on the neurobiological processes …
