Purpose
This study will examine how mental health after very stressful experiences may be related to aspects of memory. Specifically, we are looking at how these experiences and posttraumatic stress disorder (PTSD) may contribute to changes in memory and physiological state. PTSD is associated with alterations in how and when these experiences are remembered. Thus, this study aims to explore associations between PTSD and these memory-related processes.
Involvement
Participants will be asked to complete a clinical interview and two in-person visits. The clinical interview will ask about emotional well-being, including responses to trauma, and participants will also complete some questionnaires about physical health. The two lab visits will involve: 1) MRI brain scans and memory and comprehension tasks, and 2) blood pressure and heart rate measurement, as well as additional tasks testing memory and perception. In addition, participants will also complete tasks while we measure physical responses non-invasively (for example, the electrical activity of the heart, facial muscles, and skin). We will also measure these responses while participants answer some questions about the stressful or traumatic event they spoke about during the clinical interview.
Benefits
Up to $315 in compensation for eligible participants.
