Affective Image Sequence Viewing in Virtual Reality Theater Environment: Frontal Alpha Asymmetry Responses From Mobile EEG

Background: Numerous studies have investigated emotion in virtual reality (VR) experiences using self-reported data order to understand valence and arousal dimensions of emotion. Objective physiological concerning has been less explored. Electroencephalography (EEG) can be used examine correlates emotional responses such as environments. Used across varying fields research, images are able elicit a range affective from viewers. In this study, we display image sequences with annotated values on screen within theater environment. Understanding how brain activity related stimuli known ratings may contribute better understanding processing reality. Methods: We frontal alpha asymmetry (FAA) previously ratings. Twenty-four participants viewed VR while their was recorded. Participants wore the Oculus Quest headset immersed Results: Image higher elicited greater FAA scores than lower ( F [1, 23] = 4.631, p 0.042), low 7.143, 0.014). The effect power did not reach statistical significance 4.170, 0.053). determined that only high valence, sequence which significantly recorded during baseline t [23] −3.166, 0.002), suggesting most salient for participants. Conclusion: lead experiences. While findings suggest useful associations between environments, additional research individual differences informative development scenarios.
