Official Title: Effects of Trauma and Discrimination on the Social Regulation of Threat-related Vigilance and Arousal

Brief Summary: This study will examine the effects of social support on threat vigilance and arousal using eye tracking.
We will also test the moderating effects of trauma and discrimination history.

Detailed Summary: Both interpersonal trauma (IPT) and ethno-racial discrimination amplify risk for hyper-arousal symptoms of posttraumatic stress disorder (PTSD), but the mechanism of this effect is unclear.
Prior research suggests that social support plays an important role in regulating emotional responses, a process called social emotion regulation.
This study will test whether a history of IPT and/or ethno-racial discrimination influence the social regulation of arousal and vigilance.
Social regulation will be tested by contrasting responses under conditions with and without social support.

Current Primary Outcome: Participants will view 15 pictures of natural environmental scenes for 10 seconds per image.
We will use an eye tracker to examine the number of eye fixations per scene.
A greater number of fixations during the 10 second presentation of a scene would indicate greater vigilance.
