Answer:
While video games have been linked to aggression, Granic, Lobel, and Engels wrote a review article for American Psychologist about the positive social, cognitive, emotional, and motivational effects of video games.
Explanation:
According to research carried out by Granic, Lobel and Engels, most psychologists have researched about the negative effects of playing videogames, and although these are proved to be true, there still are other beneficial effects which have to be taken into consideration. This is important since videogames have evolved in both complexity and diversity as much as they have become more real and social.
