- The study investigates how stress and sex hormone levels influence fear regulation and memory extinction in men and women.
- It finds that while stress doesn't significantly affect learning of fear extinction, it impacts retention differently based on hormone status, with stressed men showing impairment and mid-cycle women performing better.
- Overall, early follicular women struggled with fear regulation regardless of stress, while those on oral contraceptives displayed variability in response to stress.
Following a traumatic event, fear dysregulation can increase the likelihood of developing post-traumatic stress disorder (PTSD). This psychopathology is twice as prevalent in women than in men. High physiological reactivity following trauma may be an early risk indicator for the development of PTSD.
