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.
有人提出，接触暴力视频游戏（VVG）会导致社交行为发生变化，例如攻击性增强。据报道，玩 VVG 的最具破坏性的影响是对暴力刺激的神经脱敏，鉴于报告的玩家数量和玩主要视频游戏的时间，这是一个主要关注点。本研究旨在调查在事件相关电位（ERP）的 P300 成分中报告的暴力刺激反应的神经脱敏是否存在。招募了 87 名参与者，并根据他们的视频游戏行为（暴力游戏玩家和非玩家）将其分为两种情况之一。参与者被动观看了从国际情感图片系统（IAPS）中选择的暴力和中性图像，记录了他们的 ERP。然后，参与者玩了一个 VVG，在观看中性和暴力 IAPS 图像时记录了 ERP。根据条件、时间和内容分析了 P300 的平均幅度。图像有显著影响，但 VVG 玩家和非玩家没有显著影响。研究结果被解释为对神经脱敏假设的证据。本研究的结果与影像学研究一致，并讨论了玩 VVG 报道的负面影响的含义。
