Therefore, in the present study, we investigated the use of DF as an educational tool in a writing and speaking course and examined the
MMORPG’s educational value for students addicted to the game. We hypothesized that subjects who were exposed to game-based
educational content would show significantly improved language expression. We also conducted a brain imaging study focused on the
P300 ERP, which is considered to be a neural correlate of Internet game dependence. The P300 has been of particular interest in research on
drug, cigarette, and alcohol use and is associated with attention allocation, intensity of processing, closure of perceptual events, and
activation of immediate memory
