Enigma virtual box unpacker 0.5511/24/2023 ![]() Since early hints from lesion research, many studies have supported the notion that emotion processing in the brain is lateralized. In summary, our findings indicate that immersive technologies such as VR can advance emotion research by providing more ecologically valid ways to induce emotion. Within the IAPS task, no significant asymmetries were detected. Asymmetry indices in the plank task revealed greater right-hemispheric lateralization during the negative VR condition, relative to the neutral VR condition and to IAPS viewing. We compared frontal alpha asymmetry between the plank and IAPS task and across valence of the conditions. Following the VR experience, participants passively viewed negative and neutral images from the international affective picture system (IAPS) outside of VR. Subjective ratings showed that the negative condition induced feelings of fear. Seventy-five healthy participants walked across a virtual plank which extended from the side of a skyscraper-either 80 storeys up (the negative condition) or at street level (the neutral condition). This pre-registered study examines the neuronal underpinnings of naturalistic fear, measured using mobile electroencephalography (EEG). More realistic paradigms using virtual reality (VR) may be better suited to investigate authentic emotional states and their neuronal correlates. However, this method lacks ecological validity, limiting generalization to real-life emotion processing. ![]() Most studies on emotion processing induce emotions through images or films.
