Summary and Keywords
In our modern age, electronic media usage is prevalent in almost every part of the world. People are more connected than ever before with easy access to highly portable devices (e.g., laptops, smartphones, and tablets) that allow for media consumption at any time of day. Unfortunately, the presence of violence in electronic media content is almost as prevalent as the media itself. Violence can be found in music, television shows, video games, and even YouTube videos. Content analyses have shown that nearly all media contain violence, irrespective of age rating (Linder & Gentile, 2009; Thompson & Haninger, 2001; Thompson, Tepichin, & Haninger, 2006; Yokota & Thompson, 2000). It is therefore important to ask: What are the consequences of pervasive exposure to screen violence? One consequence of media violence exposure, hotly debated by some in the general public, is increased aggressive behavior. This relationship was investigated in many studies using experimental, longitudinal, or cross-sectional design. These studies are summarized in meta-analyses, which support the notion that media violence increase the likelihood of acting aggressively. This link can be explained by an increase in aggressive thoughts, a more hostile perception of the environment, and less empathic reaction to victims of aggressive behavior. However, the often debated notion that media violence allows one to vent off steam, leading to a reduced likelihood of aggressive behavior, has failed to receive empirical support. The effect of media violence is not limited to aggressive behavior; as a consequence of violent media usage attentional problems arise and prosocial behavior decreases.
