电子竞技原声对选手专注度的影响分析——一项EEG研究

Effect of Game Original Sound on Players’Attention in E-sports——An EEG Study

目的:本实验通过观察脑电(EEG:electroencephalographic)Alpha节律﹑Beta节律和Theta节律的功率变化,探究电子竞技中背景音效与电子竞技操作用户大脑额叶前中区涉及注意力区域的脑活动变化关系。方法:10名csgo用户参与了本次实验,他们分别在有背景音效和无声音条件下进行了90秒的操作任务,同时使用Biopac MP150同步纪录实验期间的大脑活动情况。结果:在两种情况下进行的操作结果显示Alpha功率两种情况下无显著差异﹑Btea功率在原声音效任务中显著高于无声音任务﹑Theta功率原声音效任务中也显著高于无声音任务。结论:原声音效情况下进行电子竞技操作时额中线区域的Beta和Theta功率证实了原声条件下用户注意力更加集中,说明原声音效确实能给用户带来良好的体验,对大脑活动有积极的影响。

The purpose of this study is to examine the correlation between the game original background sound effects in E-sport and the cerebral activity in the prefrontal central region involving attention of the players through the observation of electroencephalographic(EEG)power changes of Alpha rhythm,Beta rhythm and Theta rhythm.Methods:10 csgo players participated in this experiment and respectively played the game in the presence or absence of original background sound effects for 90 seconds and Biopac MP150 was applied to record their cerebral activities simultaneously.Results:The results under these two circumstances indicated that there was no significant difference in Alpha power between the two circumstances,Btea power was significantly higher in the original sound game task than in the no-sound task,and Theta power was also significantly higher in the game original sound game task than in the no-sound task.Conclusion:The power of Beta and Theta in midline frontal region during playing the game under the condition of original sound illustrated that players were more engaged under the condition of acoustic sound effects,which indicated that original sound indubitably contributed to delivering favorable experience for players and had a positive effect on cerebral activities.
