暴力电子游戏的短期脱敏效应：两种接触方式比较

比较主、被动接触暴力电子游戏的脱敏效应，以44名男性大学生为被试，利用生物反馈仪测量被试主动参与游戏或被动观看游戏录像前后，及随后观看暴力视频过程中皮电与心率的变化（脱敏效应的生理指标）。结果表明：（1）暴力电子游戏可以产生脱敏效应。接触游戏15分钟后，暴力游戏组观看暴力视频过程中皮电的增加值明显小于非暴力游戏组；（2）游戏的接触方式对于脱敏效应的程度无显著影响，但主动参与组对于游戏内容知觉到更高的愉快与更低的沮丧

Short-Term Desensitizing Effects of Violent Video Games: Comparison Between Two Exposure Ways

This study examined the desensitizing effect of active or passive exposures to violent video games on male college students’ physiological arousal when viewing a violent film. The study employed a 2 (active or passive exposure) x 2 (violent or nonviolent video game) factorial design. Half of the forty-four participants were randomly assigned to either playing a violent video game or watching the records of someone else playing the violent game for 15 minutes, and the other half assigned to playing or watching a nonviolent video game. Then all the participants were presented with a 10-minute long violent film segment while their heart rate (HR) and galvanic skin response (GSR) were being recorded. The result showed that participants who previously played or viewed a violent video game had lower GSR while viewing the violent film than those who previously played or watched a nonviolent video game. This result demonstrated a physiological desensitization effect of exposure to violent video games on physiological arousal toward violence. However, the way of exposure, active or passive, to violent video games failed to show any influence on the degree of desensitization, although actively-playing group reported more enjoyment and less frustration than did passively-viewing group. Results were interpreted and discussed using the General Aggression model.
