Cognitive Augmentation Via Multimodal Sensing and Auricular Neurostimulation

Brief Summary

The goal of this clinical trial is to extend this period of optimal cognitive performance by applying neurostimulation to buffer health volunteers against the effects of increased levels of stress, distraction, and cybersickness. The main questions it aims to answer are: * Can we use OpenBCI's head-mounted Galea biosensor + eXtended Reality (XR) platform to measure participants' cognitive state in relation to stress, attention and cybersickness? * How does applying external neurostimulation via Spark Biomedical's Sparrow Link transcutaneous auricular neurostimulation (tAN) system enhance cognitive performance with a closed-loop interface that automatically applies neurostimulation as a function of physiologically determined stress, attention, and cybersickness metrics? Researchers will compare the active neurostimulation group to the sham neurostimulation group to see if cognitive performance is improved with stimulation. Participants will complete 4 virtual reality tasks in the lab: * 2 tasks related to attention - Flanker and Gradual-onset Continual Performance Task (GradCPT) * The Multi-Attribute Task Battery (MATB) * A cybersickness task * And a baseline session before each task * Neurostimulation intervention will occur in response to cognitive states
