暴力游戏对青少年攻击性认知影响的文化差异:基于元分析视角

Cultural Differences in the Effect of Violent Video Games on Adolescent Aggression Cognition: Based on the Perspective of Meta-analysis

对国内外现有的暴力游戏影响青少年攻击性认知的实验研究进行元分析。总共纳入24篇研究,产生28个独立样本,涉及被试2449人。结果表明,暴力游戏助长青少年攻击性认知的总效应接近中等程度;暴力游戏对青少年攻击性认知的效应受文化类型和被试群体类型的调节,但不受测验方法的影响,西方文化的效应值显著大于东方文化的效应值;其对小学生、大学生、中学生攻击性认知的影响效力依次递减,各测验方法之间的效应值差异并不显著。

Meta-analytic procedures were used to test the culture differences of violent video games on aggressive cognition for children and adolescents. Twenty four researches were identified with a total sample size of 2449 participants. The results showed that： （1） The average effect size of violent video game exposure was 0.23.
