研究表明，接触暴力媒体会增加攻击性。然而，人们对暴力媒体相关攻击行为的神经基础知之甚少。此外，很少有实验检验有关如何减少与暴力媒体相关的攻击行为的假设。在这个实验中，我们关注的是参与调节攻击性冲动的大脑区域——右腹外侧前额叶皮层（rVLPFC）。我们测试了这样的假设：通过 rVLPFC 上的阳极经颅直流电刺激 (tDCS) 进行大脑极化，可以减少与暴力视频游戏相关的攻击行为。参与者（N = 79）被随机分配玩暴力或非暴力视频游戏，同时接受阳极或假刺激。之后，参与者使用泰勒攻击范式（Taylor Journal of Personality, 35, 297–310, 1967）对表面上的伴侣进行攻击，该范式测量无端攻击和被触发攻击。在那些接受虚假刺激的人中，暴力游戏玩家的无端攻击行为明显高于非暴力游戏玩家。在那些接受阳极刺激的人中，暴力游戏玩家和非暴力游戏玩家的无端攻击行为没有差异。因此，阳极刺激减少了暴力游戏玩家无端的攻击行为。没有发现对激起攻击性的显着影响，表明针锋相对的反应。这项实验揭示了暴力媒体相关攻击行为的一个可能的神经基础——rVLPFC，这是一个参与调节负面情绪和攻击冲动的大脑区域。
Research has shown that exposure to violent media increases aggression. However, the neural underpinnings of violent-media-related aggression are poorly understood. Additionally, few experiments have tested hypotheses concerning how to reduce violent-media-related aggression. In this experiment, we focused on a brain area involved in the regulation of aggressive impulses—the right ventrolateral prefrontal cortex (rVLPFC). We tested the hypothesis that brain polarization through anodal transcranial direct current stimulation (tDCS) over rVLPFC reduces aggression related to violent video games. Participants (N = 79) were randomly assigned to play a violent or a nonviolent video game while receiving anodal or sham stimulation. Afterward, participants aggressed against an ostensible partner using the Taylor aggression paradigm (Taylor Journal of Personality, 35, 297–310, 1967), which measures both unprovoked and provoked aggression. Among those who received sham stimulation, unprovoked aggression was significantly higher for violent-game players than for nonviolent-game players. Among those who received anodal stimulation, unprovoked aggression did not differ for violent- and nonviolent-game players. Thus, anodal stimulation reduced unprovoked aggression in violent-game players. No significant effects were found for provoked aggression, suggesting tit-for-tat responding. This experiment sheds light on one possible neural underpinning of violent-media-related aggression—the rVLPFC, a brain area involved in regulating negative feelings and aggressive impulses.
