Disclaimer: The interaction between video games and behavior is complex. Below are a few selected studies from reliable sources that offer an alternative view to many views regarding the negative impact on our children’s behavior. This list is not exhaustive nor conclusive.

Gamer League is an advocate for responsible, safe, and respectful gaming, a goal that will be further refined over time. We believe that should be combined with a balanced approach to entertainment including play limits and integration with other behaviors such as exercise and social interaction.


Does Playing Violent Video Games Cause Aggression?

“the findings of the present study show that an extensive game intervention over the course of 2 months did not reveal any specific changes in aggression, empathy, interpersonal competencies, impulsivity-related constructs, depressivity, anxiety or executive control functions; neither in comparison to an active control group that played a non-violent video game nor to a passive control group.”

“To our knowledge, the present study employed the most comprehensive test battery spanning a multitude of domains in which changes due to violent video games may have been expected. Therefore the present results provide strong evidence against the frequently debated negative effects of playing violent video games.”

Do Video Games Enhance Cognition?

Cognitive improvements were not limited to action game training alone and different games enhanced different aspects of cognition. We conclude that training specific cognitive abilities frequently in a video game improves performance in tasks that share common underlying demands.

Do video games enhance task-switching abilities?

“There is now a substantial body of work demonstrating that action video game experience results in enhancements in a wide variety of perceptual skills. More recently, several groups have also demonstrated improvements in abilities that are more cognitive in nature, in particular, the ability to efficiently switch between tasks. In a series of four experiments, we add to this body of work, demonstrating that the action video game player advantage is not exclusively due to an ability to map manual responses onto arbitrary buttons, but rather generalizes to vocal responses, is not restricted to tasks that are perceptual in nature (e.g. respond to a physical dimension of the stimulus such as its color), but generalizes to more cognitive tasks (e.g. is a number odd or even), and is present whether the switch requires a goal-switch or only a motor switch.”

Do video games hurt your eyes?

“Compared with nonplayers, action-video-game players could tolerate smaller target-distractor distances. Thus, the spatial resolution of visual processing is enhanced in this population.”

Do gamer surgeons perform better?

“Past video game play in excess of 3 h/wk correlated with 37% fewer errors (P<.02) and 27% faster completion (P<.03). Overall Top Gun score (time and errors) was 33% better (P<.005) for video game players and 42% better (P<.01) if they played more than 3 h/wk. Current video game players made 32% fewer errors (P=.04), performed 24% faster (P<.04), and scored 26% better overall (time and errors) (P<.005) than their nonplaying colleagues. When comparing demonstrated video gaming skills, those in the top tertile made 47% fewer errors, performed 39% faster, and scored 41% better (P<.001 for all) on the overall Top Gun score. Regression analysis also indicated that video game skill and past video game experience are significant predictors of demonstrated laparoscopic skills.”
