摘要

Recent psychology and neuroscience studies have employed virtual reality and multisensory stimulation to accelerate and magnify emotional and cognitive processes. For this experiment, we conducted electroencephalogram (EEG) recordings of 28 individuals who watched several traffic accidents in a virtual environment using Oculus glasses, while also wearing a belt holding ten motors. The audiovisual content was projected in two different ways: (1) image and sound, and (2) image, sound, and tactile stimulation on the participants’ bodies. The results indicate an activation in orbitofrontal areas under both conditions, with the main difference being the activation of the right insula and right hemisphere temporal areas in condition 2, and left hemisphere temporal areas in condition 1. We conclude that the incorporation of a tactile stimulus synchronized with the impacts in traffic accident videos through a virtual environment accelerated emotional processes in the brain activity of the viewers. These results open up the possibility of considering tactile stimulation as a tool that can help raise awareness about reckless driving.
