NOVEL ODDBALL PARADIGM IN VIRTUAL REALITY 1 Electroencephalography (EEG) research is typically conducted in controlled laboratory settings. This limits the generalizability to real-world situations. Virtual reality (VR) sits as a transitional tool that provides tight experimental control with more realistic stimuli. To test the validity of using VR for eventrelated potential (ERP) research, we used a well-established paradigm, the oddball task. Standard stimuli were presented 80% of the time and target stimuli which were responded to, presented 20% of the time.For our first study we compared traditional to VR stimulus presentation using standard visual and auditory oddball tasks. We found that ERPs collected using VR head mounted displays and typical monitors were comparable on measures of latency, amplitude, and spectral composition. In a second study we implemented a novel depth-based oddball task. We demonstrated that typical oddball ERPs elicited by presentation of near and far stimuli. Interestingly, we observed significant differences in early ERPs components between near and far stimuli, even after controlling for the effects of the oddball task.Current results suggest that VR can serve as a valid means of stimulus presentation in novel or otherwise inaccessible environments for EEG experimentation. We demonstrated the capability of the depth-based oddball to reliably elicit P3 responses, and find an interaction between the depth at which objects are presented and early ERP response. Further research is warranted to better explain this relationship of depth on the ERP components.
