Summary

This study tests whether a non-invasive device that gently stimulates a nerve in the ear can reduce stress during performance tasks like public speaking. Two hundred adults will be randomly assigned to receive either active or placebo stimulation while completing a stressful speech or a calm writing task. Researchers will measure self-reported stress and heart rate to see if the device helps people feel calmer under pressure.
