In the past two weeks, there has been a considerable amount of popular press attention to some new studies on video games:

Three studies about video games were just released in a book by Anderson, Gentile and Buckley.  The first study found that cartoonish violence had the same size effect on children as graphic violence had on college students.  The second study found that teens who played violent video games were more hostile, believed violence was common, and were generally more aggressive than those who did not play violent games.  The third study found that school-age children who played violent games at the beginning of the year had more aggressive thoughts and behaviors at the end of the year.

A meta-analysis by Ferguson is forthcoming in the journal Aggression & Violent Behavior.  His paper focuses on whether there is a publication bias toward video game studies with large effects sizes, as well as which measures of aggressive behavior are reliable. 

An experimental study by Devilly is forthcoming in the journal Psychology, Crime and Law.  His paper focuses on whether people’s temperament is a predictor for how aggressive they will behave after playing video games.
