Video games have become an immensely popular form of entertainment over the past few decades. What was once considered a niche hobby is now a multi-billion dollar industry with millions of active players worldwide. As with any new technology or media, video games have also become a target of criticism and controversy regarding their potential effects on players. While games are viewed as a harmless leisure activity by many, others argue they can promote negative behaviors or isolate players from human interaction. This paper will examine the existing research on how video games may impact players both positively and negatively.
There is significant debate around whether violent video games desensitize players or promote aggression. Some research shows short-term increases in aggressive thoughts and feelings after playing violent games, but the long-term effects are less clear (Anderson et al., 2010). A meta-analysis of 135 independent studies found a small but significant association between violent video game exposure and increases in aggressive behavior, aggressive cognitions, and aggressive affects both immediately and over time (Anderson et al., 2010). Other researchers argue this link has been overstated and that factors like poor parenting or preexisting personality traits are better predictors of aggression than media consumption alone (Ferguson, 2015).
Causation is also difficult to prove given that “aggressive individuals may be drawn to violent media in the first place” (Ferguson, 2015, p. 390). Some studies even found cathartic or stress-reducing benefits to playing violent games, though the evidence is mixed (Ferguson, 2015). Overall, the data suggests violent games may increase aggression for some individuals under certain circumstances, but does not demonstrate a simple or inevitable cause-and-effect relationship at a population level. More research is still needed to understand for whom and under what conditions negative effects may occur.
Some research also considers whether positive impacts of video games have been overlooked. For example, properly designed games have shown promise in enhancing cognitive abilities like visual selective attention, reasoning skills, and problem-solving (Granic et al., 2014). Action games in particular seem to temporarily improve certain types of visual processing (Granic et al., 2014). This suggests games are not inherently “good” or “bad” – their impacts depend critically on structural characteristics as well as an individual’s preexisting traits and play behaviors. Well-designed games could potentially serve as educational tools or have cognitive benefits when used in moderation.
Concerns about excessive gaming focus mainly on the potential for addiction. Video game addiction is now recognized as a mental health condition by the World Health Organization, though estimates of clinical prevalence vary considerably (WHO, 2018). Excessive gaming is defined as poorly controlling urges to play, prioritizing gaming over other life activities and relationships, and continuing to play despite negative consequences (WHO, 2018). Addiction diagnoses require impairments in daily life functioning, which are not experienced by the vast majority of regular gamers (King et al., 2013). As for any highly engaging activity, uncontrolled binge-gaming can potentially interfere with responsibilities for some vulnerable individuals under certain conditions, such as during times of stress. But controlled, moderate play appears unlikely to cause harm on its own for most.
Some research on social impacts has assessed whether gaming displaces in-person interactions or fosters social skills. Findings are mixed. Online gaming can facilitate new social connections and teamwork for some players (Kowert et al., 2014). But heavy use may correlate with weaker real-world social ties for others, depending on an individual’s preexisting traits and online vs offline friend networks (Kowert et al., 2014). Overall, social effects seem to depend more on how games are used than any inherent qualities. Games are neither inherently socially isolating nor do they necessarily develop skills – players still need to balance real and virtual relationships however works best for their lives and support systems.
Current research suggests video games have a complex relationship with players that cannot be reduced to simplistic “effects” notions. Outcomes depend greatly on individual characteristics like personality and mental health as well as contextual factors like game content and play behaviors. Causation is difficult to prove given that certain traits may predispose both game preferences and life outcomes. Overall, properly designed games used in moderation seem unlikely to significantly harm well-adjusted individuals, and may even have benefits like enhanced cognition for some. Uncontrolled binge-playing could potentially interfere with life responsibilities or relationships on a case-by-case basis, especially for those with prior psychological vulnerabilities. More high-quality longitudinal research could continue improving understanding of potential benefits and risks across diverse players and game contexts over both the short and long term.
