Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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 Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
