This study was designed to investigate the levels of aggression of men and women following exposure to videogames, and to study the impact of character identification. The 59 participants played their assigned game, Mortal Kombat on Nintendo Wii or Halo 2 on the Xbox, for 45 minutes with a partner. The results showed that individuals may be becoming more desensitized to graphic content and spend large periods of time exposed to aggressive game environments. Results showed that since desensitization appears to be occurring, overall aggression is actually going down and violence is not becoming as shocking anymore the longer you play. Results also showed men had higher aggression levels post-game playing and that they identified with the characters more strongly than women. Videogame rating boards could use this information to help determine aggressive levels of future videogames.
