In what is possibly one of the most obvious research results to
come out of gaming recently, a study has found that people who play violent videogames, such as first-person shooters,
become less sensitive to violent images. Measuring the brain's response to a variety of images, academics at the
University of Missouri-Columbia found that those who played violent games were less responsive to violent imagery than
those who did not play.
This is another weapon in the arsenal of those opposing
violent games, although the study is not specific in its
conclusions. Game players may have reduced inhibitions and thus may be more aggressive, but similarly they may find it
easier to cope with shocking sights, preparing them for careers in the military or as doctors. It's unlikely that
opponents of gaming will hit on these positive aspects, though.
