Abstract
This research was performed to analyze quantitatively how spiritual stress affects some ERPs on human through sight stimulus after the settlement of visual and auditory integration environment in three dimension space. We measured ERPs in the normal state and spiritual stress sessions separately. The subjects were 10 normal men and women and vital signs was recorded from Fpl, Fz, Cz, Pz, O1, O2's scalps. The experiment was done in isolated room where electro-magnetic effect do not affect. The result showed that P300's amplitude was a little higher under stress session and latent period in this resulted in longer time. We recorded through voltage variation the activity of brain which is in charge of human's perception. cognition, process of action and evaluated the effect of spiritual stress. We expected that the result of this research can be used to evaluate the malfunction of brain.
