【摘要】 使用事件相关电位(ERPs),探索个体短期接触暴力游戏所产生的认知、情绪变化。分别以暴力或非暴力游戏作为实验材料。使用三刺激的oddball范式,选取IAPS情绪图片作为刺激材料,P300成分作为指标。结果发现:观看暴力图片时,暴力游戏组的P300波幅显著大于非暴力游戏组。结果表明,暴力游戏导致个体短时间内情绪唤醒增强,对暴力场景和信息更为敏感。更多还原

【Abstract】 The present study explored whether the exposure to violent media increases aggression,though the mechanisms of this effect have remained elusive. Exploring whether the exposure to violent media leads to desensitization or sensitization for violence is important. All subjects performed a three-stimulus oddball task to investigate how the shortterm violent media game experience influences the amplitude and latency of P300 component,when individuals view violent emotional pictures. The ERP data indicated that the violent game player’s P300 amplitude was significantly larger than non-violent game player’s when they view three type images( violent images,non-violent images and neutral images. These results confirm that short-term exposure to violent media games induces sensitization to violent cues rather than desensitization. Playing violent games also leads to emotional arousal.更多还原
