Introduction: this research investigated the effects of violent and football video games on cognitive functions, cortisol levels, and brain waves. methods: a total of 64 participants competed in a singleelimination tournament. saliva samples of all players were obtained before and after the games for the assessment of cortisol levels. the cognitive performances of the players were also assessed by paced auditory serial addition test. moreover, the electroencephalogram recording was conducted during the games. results: the results showed that salivary cortisol levels significantly decreased after playing both games. also, playing the football game increased reaction time, whereas decreased sustained attention and mental fatigue. conclusion: conversely, following playing a violent game, the reaction time decreased, and sustained attention and mental fatigue increased. furthermore, the results of the eeg recording revealed that playing a violent game engaged more brain regions than the football game. in conclusion, playing violent game more effectively improved cognitive performances in the players than the football game.
