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 single-elimination 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.
引言:本研究调查了暴力电子游戏和足球电子游戏对认知功能、皮质醇水平及脑电波的影响。 方法:共有64名参与者参加了一场单败淘汰制比赛。在比赛前后采集所有选手的唾液样本以评估皮质醇水平。选手的认知表现也通过听觉节奏连续加法测试进行评估。此外,在比赛期间进行脑电图记录。 结果:结果显示,玩这两种游戏后唾液皮质醇水平均显著下降。此外,玩足球游戏会增加反应时间,而持续注意力和精神疲劳则会降低。 结论:相反,玩暴力游戏后,反应时间缩短,持续注意力和精神疲劳增加。此外,脑电图记录结果显示,玩暴力游戏比玩足球游戏激活的脑区更多。总之,与足球游戏相比,玩暴力游戏能更有效地提高玩家的认知表现。
