Fear Of Positive Evaluation And Negative Affect From Inclusion In Cyberball, Jason Ted Grossman
Fear Of Positive Evaluation And Negative Affect From Inclusion In Cyberball, Jason Ted Grossman
Arts & Sciences Electronic Theses and Dissertations
Fear of positive evaluation (FPE) is a construct related to social anxiety that involves discomfort when receiving positive attention and feedback from others. FPE research has increased over the past decade, and results suggest that it may be an important part of social anxiety for some individuals; however, it is not yet known whether FPE may also include discomfort from being included in social situations. Level of inclusion was hypothesized to moderate the relationship between FPE and negative affect from being over included such that those with high FPE would feel more uncomfortable the more they were included. To test …
Neuroticism And Stressful Life Events: Probing Mechanisms Underlying Vulnerability To Stress-Related Depression, Erin Bondy
Arts & Sciences Electronic Theses and Dissertations
Elevated neuroticism (N) potentiates the depressogenic effects of stressful life events (SLEs). We first replicate this association using longitudinal data (N=971 older adults) from the St. Louis Personality and Aging Network (SPAN) study. Here, SLEs prospectively predicted future depressive symptoms, especially among those reporting elevated N, even after accounting for prior depressive symptoms and previous SLE exposure (NxSLE interaction: p=0.016, ΔR2=0.003). These findings were further replicated in cross-sectional analyses of the Duke Neurogenetics Study (DNS), a young adult college sample with neuroimaging data (n=1,343: NxSLE interaction: p=0.019, ΔR2=0.003). Because evidence suggests that stress may promote depression …
Effort, Avolition And Motivational Experience In Schizophrenia: Analysis Of Behavioral And Neuroimaging Data With Relationships To Daily Motivational Experience, Adam Culbreth
Arts & Sciences Electronic Theses and Dissertations
Recent research has suggested an association between motivational impairment in those with schizophrenia and reduced willingness to expend effort on experimental tasks. However, few studies have examined the neural correlates of effort-based decision-making in those with schizophrenia. In the current study, we aimed to examine willingness to expend effort, the associated neural circuitry of effort-based decision-making, and the impact of experimentally-defined effort-based decision-making on daily motivational experience in schizophrenia. We recruited 28 individuals with schizophrenia and 30 healthy controls to perform an effort-based decision-making task while undergoing fMRI scanning. In order to assess whether willingness to expend effort was associated …
Spatial Navigation Ability As A Predictor Of Increased Clinical Impairment, Taylor Hendershott
Spatial Navigation Ability As A Predictor Of Increased Clinical Impairment, Taylor Hendershott
Arts & Sciences Electronic Theses and Dissertations
Spatial navigation deficits are observed in Alzheimer disease (AD) cross-sectionally, but prediction of longitudinal clinical decline has been less examined. Cognitive mapping (CM) was assessed in 95 participants and route Learning (RL) was assessed in 65 participants at baseline. Clinical progression over an average of 4.16 years was assessed using the Clinical Dementia Rating scale. Relative predictive ability of these tasks was compared to episodic memory, hippocampal volume and cerebrospinal fluid (CSF) biomarkers (ptau181/Aβ42 ratio). CM and RL were significant predictors of clinical progression (ps181/Aβ42 in prediction (psTaken together the results suggest that baseline spatial navigation …

Examining Emotional Pain Among Individuals With Chronic Physical Pain: Nomothetic And Idiographic Approaches, Madelyn Frumkin
Examining Emotional Pain Among Individuals With Chronic Physical Pain: Nomothetic And Idiographic Approaches, Madelyn Frumkin
Arts & Sciences Electronic Theses and Dissertations
Pain is often conceptualized as an experience that is both physical and emotional. These two components are often difficult to distinguish, which may contribute to the experience of chronic physical pain without an apparent physical cause. In the current two studies, I sought to examine whether emotional pain is associated with physical pain severity for individuals with chronic pain. Emotional pain and the more specific experiences of psychological and social pain have been defined as the experience of pain affect in response to non-physical stimuli (i.e., thwarted belongingness, loss, social rejection). In Study 1, I found that emotional and psychological …
