Abstract

Efficacious interventions soon after trauma exposure to prevent posttraumatic stress disorder (PTSD) are scarce. Evidence suggests that post-trauma, reminder cues to reactivate trauma memory followed by a cognitive visuospatial task, such as Tetris, reduce later intrusive images. Furthermore, studies indicate that aerobic exercise may reduce PTSD symptoms. The present study aimed to test whether playing Tetris, without prior reminder cues, after an experimental trauma limits the development of analogue symptoms and to compare Tetris to aerobic exercise, which could plausibly alter cognitive-affective processing of the trauma as well.
