Summary

University of California, Los Angeles researchers will recruit healthy participants and anxious participants (those diagnosed with social anxiety disorder) age 18-55 years old to participate in a study examining whether the ability of social support figure reminders to prevent the acquisition of fear in healthy participants extends to those with anxiety disorders.

After being recruited from the UCLA community (healthy participants, n = 50) or referred by treatment providers at the Anxiety and Depression Research Center at UCLA (anxious participants, n =50) and undergoing a telephone screening and in-person screening, 100 participants will be enrolled in the study. During the experiment, all participants will undergo the same procedures: undergoing fear acquisition procedures--the repeated pairing of a neutral image with a mild electric shock that ultimately leads to the association of threat of shock with the image--in the presence of an image of a social support figure (provided by participants) and an image of a smiling stranger.

BEHAVIORAL

Social support image

An image of a social support figure specific to each participant (provided by the participant) will be present while participants undergo a fear acquisition procedure. Specifically--the image will be presented alongside a neutral image that is either consistently paired with shock (CS+) or never paired with shock (CS-), so that assessment of whether there are differences in fear responding (evaluated via SCR) due the shock pairing can be assessed. This is a typical fear acquisition procedure, and a typical outcome would be for SCR to be higher for the CS+ compared to the CS- toward the end and following the procedure, indicating that the CS+ is now associated with the aversive shock and is bringing about a fear response (in this case indexed by increased sympathetic nervous system activity preparing the body to fight or flee).
