先前的研究表明，媒体暴力曝光会导致对暴力的脱敏，理论上会增加攻击性。然而，迄今为止还没有研究证明这种关联。在目前的实验中，参与者玩暴力或非暴力视频游戏，观看暴力和非暴力照片，同时测量他们的大脑活动，然后给一个表面上的对手不愉快的噪音爆炸。参与者低以前暴露于视频游戏暴力谁玩暴力（相对于非暴力）游戏显示事件相关脑电位（ERP）的P3组件减少暴力图像（表明生理脱敏），这种大脑反应介导的视频游戏内容对随后的攻击行为的影响。这些数据提供了第一个将暴力脱敏与攻击性增加联系起来的实验证据，并表明这一过程的神经标记至少可以部分解释暴力游戏暴露和攻击性之间的因果关系。(C)2011 Elsevier Inc.

Previous research has shown that media violence exposure can cause desensitization to violence, which in theory can increase aggression. However, no study to date has demonstrated this association. In the present experiment, participants played a violent or nonviolent video game, viewed violent and nonviolent photos while their brain activity was measured, and then gave an ostensible opponent unpleasant noise blasts. Participants low in previous exposure to video game violence who played a violent (relative to a nonviolent) game showed a reduction in the P3 component of the event-related brain potential (ERP) to violent images (indicating physiological desensitization), and this brain response mediated the effect of video game content on subsequent aggressive behavior. These data provide the first experimental evidence linking violence desensitization with increased aggression, and show that a neural marker of this process can at least partially account for the causal link between violent game exposure and aggression.
