Abstract

ABSTRACT A large body of research exists on the causal relationship between violent video game (VVG) consumption and aggression. However, no meta-analytic studies to date have specifically examined the influence of age on these effects. We investigated the age-dependent relationship between VVG consumption and subsequent physically aggressive behavior in a meta-analytic procedure based on longitudinal studies. Further exploratory analyses addressed the moderating effect of the year of data collection. A random-effects meta-analysis with 30 effect sizes from 21 studies (N = 15,836) yielded a significant and relevant positive effect of VVG on subsequent physically aggressive behavior (r = .21). The effect was reduced but maintained at r = .11 when controlling for aggression at T1. Polynomial regression showed a significant U-shaped age trajectory with a peak in early adolescence at the age of 14. Year of data collection did not correlate with the effect size. Consequently, we confirm the results of other meta-analyses, with the added finding of a peak of effect sizes in early adolescence. The empirical finding provide support for basing age ratings for game publication on potential adverse behavioral effects.

暴力电子游戏对攻击性的纵向、年龄依赖效应的元分析

关于暴力电子游戏(VVG)消费与攻击性之间的因果关系，已有大量研究。然而，到目前为止，还没有荟萃分析研究专门研究了年龄对这些影响的影响。我们在纵向研究的基础上，通过荟萃分析程序调查了VVG消费与随后的身体攻击行为之间的年龄依赖关系。进一步的探索性分析解决了数据收集年份的调节效应。一项来自21项研究(N = 15,836)的30个效应量的随机效应荟萃分析显示，VVG对随后的身体攻击行为有显著且相关的积极影响(r = .21)。当控制T1时的攻击性时，效果有所降低，但保持在r = 0.11。多项式回归显示出显著的u型年龄轨迹，在青少年早期14岁达到高峰。数据收集年份与效应大小无关。因此，我们确认了其他荟萃分析的结果，并增加了在青春期早期效应大小达到峰值的发现。这一实证发现为基于潜在不良行为影响的游戏发行年龄分级提供了支持。

期刊介绍： Media Psychology is an interdisciplinary journal devoted to publishing theoretically-oriented empirical research that is at the intersection of psychology and media communication. These topics include media uses, processes, and effects. Such research is already well represented in mainstream journals in psychology and communication, but its publication is dispersed across many sources. Therefore, scholars working on common issues and problems in various disciplines often cannot fully utilize the contributions of kindred spirits in cognate disciplines.
