Gentile, D. A. (2010). Video games affect the brain—for better and worse. In D. Gordon (Ed.) , Cerebrum 2010: Emerging ideas in brain science (pp. 71-80). Washington, DC US: Dana Press.

(from the chapter) We hear conflicting reports about how video games affect our brains. One study will suggest that video games help us learn; another might imply that they make young people more aggressive. Douglas A. Gentile argues that how games influence our brains is not an either-or proposition; games can have both positive and negative consequences, and which consequences researchers find depends on what they are testing. Gentile proposes that researchers focus their investigations on five attributes of video game design to tease out these disparate effects. (PsycINFO Database Record (c) 2012 APA, all rights reserved)
