Burgess, S. R., Stermer, S., & Burgess, M. R. (2012). Video game playing and academic performance inc college students. College Student Journal, 46(2), 376-387.

The relations between media consumption, especially TV viewing, and school performance have been extensively examined. However, even though video game playing may have replaced TV viewing as the most frequent form of media usage, relatively little research has examined its relations to school performance, especially in older students. We surveyed 671 college students concerning their history of video game usage and school performance. In general, video game players had lower GPAs, but this finding varied by gender. Video game players also reported a greater likelihood of playing video games to avoid doing homework. There were consistent negative associations between liking to play violent video games and school performance. (PsycINFO Database Record (c) 2012 APA, all rights reserved)
