The Effects Of Conceptually Driven Versus Data-Driven Encoding On Traumatic Memory Amplification, Kelsey N. Barnett
The Effects Of Conceptually Driven Versus Data-Driven Encoding On Traumatic Memory Amplification, Kelsey N. Barnett
Student Theses
Our research examines whether the way in which a person encodes a traumatic experience affects their post traumatic stress disorder (PTSD) symptoms and ability to remember the trauma over time. In our first study, we were interested in establishing whether people have any existing beliefs about how encoding processes influence the development of PTSD. In line with Ehlers and Clark’s (2000) theory, we hypothesized that people would be more likely to indicate that exclusively paying attention to sensory details during a traumatic event contributes to the formation of traumatic memories and PTSD. To test this hypothesis, we designed a simple …

Neural Hypervigilance In Trauma-Exposed Women, Seungyeon A. Yoon
Dissertations, Theses, and Capstone Projects
Trauma-exposed people often experience hypervigilance, which is a tonic condition of elevated alertness and excessive scanning for potential threat. A cardinal feature of hypervigilance is that no actual threat is needed to evoke or maintain the over-alertness and heightened affective response. However, most neuroimaging research in trauma to date has only focused on reactivity to an actual threat. Thus, the overarching aim of this dissertation was to investigate neural signatures and salivary markers of post-trauma hypervigilance in the absence of threat that can cause impairment in daily functioning and contribute to developing other trauma-related symptoms such as heightened threat reactivity. …
