Video games are a popular form of entertainment. But can video games have a negative impact on your focus? Many studies show that both duration of exposure and level of violence of video games appear to be associated with concentration difficulties. However, whilst much attention has been given to the affects of long duration of game playing to violent video games (1), little is known on the impact that short exposure to less violent video games can have. Jacob Brawer, a Clinical Neuroscience Research Intern at David Geffen School of Medicine at UCLA, has just published a study in the Journal of Young Investigators (JYI) providing the first evidence that even short-term video gaming can significantly impact both the concentration and attention of players (2)
