Assessing The Long-Term Sequelae Of Mild Traumatic Brain Injury, Janna Mantua
Assessing The Long-Term Sequelae Of Mild Traumatic Brain Injury, Janna Mantua
Doctoral Dissertations
A mild traumatic brain injury (mTBI), also known as a concussion, is defined as an injury that results in an alteration of consciousness or mental status. Previous studies have shown mTBI populations experience a number of chronic (> 1 year) symptoms, such as sleep disturbances (e.g., sleep stage alterations), mood alterations (e.g., depressive symptoms), and cognitive alterations (e.g., poor concentration). The three chapters of this dissertation sought to explore these long-term sequelae and the possible interrelations between them. In the first experiment, sleep-dependent memory consolidation of neutral stimuli was probed in a chronic mTBI sample and a control, uninjured sample. …
Age Group Differences In Affect Responses To A Stressor, Molly Mather
Age Group Differences In Affect Responses To A Stressor, Molly Mather
Masters Theses
Older adults may be better able to modulate their emotional experiences than younger adults, and thus may recover more quickly from negative stressors. Additionally, older adults may be more likely to experience co-occurrence of negative and positive emotions in the setting of negative stressors, which may facilitate emotion recovery. To date, few studies have investigated the nature of age group differences in spontaneous emotional responses to a standardized stressor. The current study utilizes a laboratory mood manipulation to determine age group differences in emotion recovery in negative and positive affects, as well as age group differences in the co-occurrence of …
Borderline Personality And Risk-Taking: Examining The Role Of Impulsivity Across Domains, Colten Karnedy
Borderline Personality And Risk-Taking: Examining The Role Of Impulsivity Across Domains, Colten Karnedy
Masters Theses
Individuals with borderline personality disorder (BPD) and high levels of BPD traits have demonstrated greater rates of engagement in risky, self-destructive behaviors compared to healthy controls. Specifically, impulsivity has been theorized to underlie many of these risky behaviors. Although existing self-report literature suggests that individuals with BPD are more impulsive than controls, evidence from behavioral measures remains inconclusive. Likewise, there is scant research examining specific domains of impulsivity associated with risky behaviors in BPD, which is problematic given that impulsivity is a diagnostic criterion for BPD. Thus, the proposed research aims to bridge this gap in the literature by examining …
