It has been proposed that exposure to violent video games (VVGs) resulted in alterations of social behaviors such as increased aggression. The most damaging reported effect of playing VVGs is neural desensitization to violent stimuli and this is a major concern given the reported number of players and time spent playing major video game titles. The aim of this study was to investigate the existence of neural desensitization that was reported at the P300 component of event-related potentials (ERPs) in response to violent stimuli. Eighty-seven participants were recruited and placed into one of two conditions based on their video gaming behavior (violent games players and nonplayers). ERPs were recorded from participants who passively viewed violent and neutral images selected from the International Affective Picture System (IAPS). The participants then played a VVG, postplaying ERPs were recorded while viewing the neutral and violent IAPS images. The mean amplitudes of the P300 were analyzed with respect to condition, time, and content. There was a significant effect of image but not of VVG player and nonplayer. The results were interpreted as evidence against the neural desensitization hypothesis. The findings of this study are consistent with imaging research and the implications for the reported negative effects of playing VVGs are discussed.

暴力视频游戏和P300：没有证据支持神经脱敏假说

已经提出，暴露于暴力视频游戏（VVG）会导致社会行为的改变，例如侵略性增加。据报道，玩VVG最具破坏力的作用是对暴力刺激产生神经脱敏，鉴于已报道的玩家数量和花费在玩主要视频游戏上的时间，这是一个主要问题。这项研究的目的是调查存在神经脱敏的情况，该反应在事件相关电位（ERPs）的P300成分上对暴力刺激有反应。根据他们的视频游戏行为（暴力游戏玩家和非玩家），招募了87位参与者并将其置于两个条件之一。记录参与者的ERP，这些参与者被动地观看了从国际情感图片系统（IAPS）中选择的暴力和中性图像。参与者随后播放了VVG，并在观看中性和暴力的IAPS图像时记录了后播放的ERP。根据条件，时间和含量分析了P300的平均振幅。图像效果显着，但VVG播放器和非播放器没有。结果被解释为反对神经脱敏假说的证据。这项研究的结果与影像学研究相一致，并讨论了演奏VVG对负面影响的影响。结果被解释为反对神经脱敏假说的证据。这项研究的结果与影像学研究相一致，并讨论了演奏VVG对负面影响的影响。结果被解释为反对神经脱敏假说的证据。这项研究的结果与影像学研究相一致，并讨论了演奏VVG对负面影响的影响。
