中文摘要：

本研究采取前后测实验设计，以内隐联想测验和Buss的攻击性问卷为研究工具，探讨了媒体暴力对大学生攻击性的长时效应和短时效应。结果发现：（1）个体实验前接触媒体暴力的程度越强烈，内隐攻击性越强，外显攻击性也越强；（2）接触暴力视频游戏10分钟就会增强个体的内隐攻击性，接触非暴力视频游戏10分钟对个体的内隐攻击性没有影响；接触暴力和非暴力视频游戏10分钟对个体的外显攻击性没有影响；（3）外显攻击性基线水平和游戏类型的交互作用不显著；内隐攻击性基线水平和游戏类型交互作用显著。内隐攻击性基线水平较高的个体，游戏类型对其内隐攻击性的影响差异不显著；内隐攻击性基线水平较低的个体，暴力视频游戏增加了他们的内隐攻击性，非暴力视频游戏对他们的内隐攻击性没有影响。
