The purpose of this study is to better understand how ear stimulation techniques may impact how people think about themselves in social situations. The goal is to identify how the addition of ear stimulation can impact cognitive processes, including the ways that people think about themselves in social situations and attend to or process social information, that underly an activity known as "self-imagery rescripting." Eligible individuals who are between the ages of 18 and 65 years will complete a variety of activities after providing consent to study participation. These include: (1) completing questionnaires on the computer, (2) completing tasks similar to a video game on the computer, (3) having an electrode attached to their ear that will stimulate nerve activity, (4) completing an interview about how they feel in social situations, and (5) engaging in an activity during which they will be prompted about how they see themselves in social situations. Throughout these activities, participants also will be asked to wear a variety of sensors, bundled together in a cap for their head and individually on other parts of their body, that will collect information about brain activity, heart rate, and eye blinking. Participation in this research study is entirely voluntary and will last approximately 3 hours during a single session at the Medical University of South Carolina in Charleston. Participants will be compensated for their time.

There are some risks associated with this study. Some survey questions ask about personal thoughts and feelings. Ear stimulation may cause tingling sensations or irritation around the ear. Thinking and talking about how one sees themselves in social situations may be distressful.

There are no direct benefits to participants. This study will help researchers better understand how ear stimulation can improve the strategies that can help the way that people think about themselves in social situations.
