This research investigated the effects of violent and football video games on the cognitive functions, cortisol level and variations of brain waves. A total of 64 participants competed in a single-elimination tournament. Saliva samples of all players were obtained before and after games for assessment of cortisol levels. The cognitive performances of player were assessed by PASAT cognitive test. Moreover, EEG recording was conducted during these games. Analysis showed that salivary cortisol levels were significantly decreased after playing both games. In addition, football game was associated with increased reaction time, decreased sustained attention and mental fatigue. Conversely, after violent game reaction time was decreased and sustained attention and mental fatigue were increased. Furthermore, the results of EEG recording revealed that violent game engaged more brain regions than football game. In conclusion , violent game more effectively improved cognitive performances in the players than football game.
