Chronic Pain Acceptance: Optimism Mediates The Relation Between Dispositional Mindfulness And Pain Acceptance, Kelli Miles

Electronic Theses and Dissertations

ABSTRACT

Chronic pain is associated with many indicators of maladjustment. We expected that five individual components of dispositional mindfulness would be positively associated with pain willingness (Hypothesis 1) and activity engagement (Hypothesis 2). A mediational hypothesis was tested, whereby dispositional mindfulness would be positively associated with optimism and optimism would in turn be positively associated with both pain willingness and activity engagement (Hypothesis 3). Both Hypothesis 1 and 2 were partially supported. Acting with awareness and nonjudging were the only mindfulness components that were positively associated with pain willingness. Other components of mindfulness were either negatively associated with pain willingness …

Resilience Among Survivors Of Adverse Childhood Experiences In Appalachia, Bridget Jeter

Electronic Theses and Dissertations

The empirical investigation of adverse childhood events (ACEs) and their relationship with health and well-being outcomes in later life is increasing. Less is known about factors that may promote resilience for those who have survived such challenges, such as how resilience may be facilitated for those with ACEs residing in a marginalized region such as South Central Appalachia. Multidimensional spirituality, social support, stigma related to ACEs, and Appalachian acculturation may serve as both valid cultural factors and potential indicators of resilience. Cross-sectional, simultaneous multiple regression analysis was performed on data collected from 272 adult patients of a South Central Appalachian …

Threatening Instructions During A Hurricane Influence Risk Perceptions: The Case Of Fear Appeals And Changing Hurricane Projections, Daphne Whitmer

Electronic Theses and Dissertations

The goal of this research was to examine the effectiveness of persuasive language in the protective action recommendation of an emergency warning, which instructs people how to prepare and stay safe. Study 1 was a pilot study, which suggested that participants were able to make distinctions between hurricane categories. In study 2, the presence of fear language and second-person personal pronouns (i.e., "you") in a recommendation was manipulated. Overall, fear language was more influential than a pronoun on risk perceptions. To understand how context influences risk perceptions, participants in study 3 made decisions after each piece of information received. The …

Understanding The Relationship Between Perfectionism And Health: Mediational Effects Drug Use, Sarah Nelsen

Electronic Theses and Dissertations

Past research has provided evidence on the consequences of perfectionism. One particular consequence of perfectionism is that of general health. Research has suggested that perfectionism type influences general mental health. Using the 3-cluster perspective of perfectionism by Slaney, Rice, Mobley, Trippi, & Ashby (2001), the current work investigates the mediating effects of drug use on the relationship between perfectionism clusters and general mental health, in the context of Conservation of Resources Theory (COR; Hobfoll, 1989). Adaptive perfectionists had higher general mental health compared to non-perfectionists and maladaptive perfectionists. However, the three clusters of perfectionism did not differ in drug use …

Subjective Measures Of Implicit Categorization Learning, Audrey Zlatkin

Electronic Theses and Dissertations

The neuropsychological theory known as COVIS (COmpetition between Verbal and Implicit Systems) postulates that distinct brain systems compete during category learning. The explicit system involves conscious hypothesis testing about verbalizable rules, while the implicit system relies on procedural learning of rules that are difficult to verbalize. Specifically from a behavioral approach, COVIS has been supported through demonstrating empirical dissociations between explicit and implicit learning tasks. The current studies were designed to gain deeper understanding of implicit category learning through the implementation of a subjective measure of awareness, Meta d', which until now has not been validated within a COVIS framework. …

Defining The Relationship: Intentional Decision-Making And Sexual Risk In Adolescent And Young Adult Romantic Relationships, Kayla Knopp

Electronic Theses and Dissertations

This dissertation presents three manuscripts addressing different sets of findings related to the "defining the relationship" (DTR) talk in adolescents' and young adults' romantic relationships. Paper 1 describes descriptive results from two studies, one utilizing a college undergraduate young adult sample (N = 341) and the other using a nationwide online sample of 15 to 17-year-old adolescents (N = 248). Key findings from Paper 1 indicate that DTR talks were used frequently in the relationships of young people, and were associated with relationship commitment and sexual behaviors. Paper 2 describes more in-depth analyses testing associations between having a …

The Effects Of Presence And Cognitive Load On Episodic Memory In Virtual Environments, Paul Barclay

Electronic Theses and Dissertations

Episodic memory refers to an individual's memory for events that they have experienced in the past along with the associated contextual details. In order to more closely reflect the way that episodic memory functions in the real world, researchers and clinicians test episodic memory using virtual environments. However, these virtual environments introduce new interfaces and task demands that are not present in traditional methodologies. This dissertation investigates these environments through the lenses of Presence and Cognitive Load theories in order to unravel the ways that basic technological and task differences may affect memory performance. Participants completed a virtual task under …

If A Virtual Tree Falls In A Simulated Forest, Is The Sound Restorative? An Examination Of The Role Of Level Of Immersion In The Restorative Capacity Of Virtual Nature Environments, Jessica Michaelis

Electronic Theses and Dissertations

Stress and cognitive fatigue have become a pervasive problem, especially in Western society. Stress and cognitive fatigue can have deleterious effects not only on performance, but also on one's physical and mental health. This dissertation presents a study in which the aim is to investigate the effects of virtual nature on stress reduction and cognitive restoration. Specifically, this study assessed the effects of Immersion (Non-immersive, Semi-immersive, Fully-immersive) and Exploration (Passive vs Active) on stress reduction and cognitive restoration. Additionally, restoration from the most effective virtual nature environment was compared to that of taking an active coloring break. Eighty-three university students …

The Effect Of Reliability Information And Risk On Appropriate Reliance In An Autonomous Robot Teammate, Andrew Talone

Electronic Theses and Dissertations

This research examined how information regarding a robot teammate's reliability and the consequences for mistakes made by a robot in its task influence reliance on the robot by a human teammate. Of interest in this research was the notion of appropriate reliance: relying on a robot teammate's decisions when it is performing well and not relying on its decisions when it is performing poorly. An experiment was conducted in which participants interacted with an autonomous robot teammate while performing a cordon and search operation within a virtual reality simulation environment. Participants were responsible for monitoring the perimeter of a search …
