Here’s a brief study conclusion I found, entitled “Video Games and the Brain,” published in Science Teacher in 2008, and linked here: http://eds.a.ebscohost.com.gate.lib.buffalo.edu/ehost/detail?sid=0f157b2b-f5d2-4aea-b030-7f45cf756b28%40sessionmgr4003&vid=1&hid=4205&bdata=JnNpdGU9ZWhvc3QtbGl2ZSZzY29wZT1zaXRl#db=eue&AN=508053345
An experiment on “territoriality” of men vs. women was conducted, and a simple computer game was used to test this. The findings were unsurprising, as far as I can tell, indicating that males were more territorial than females.
There are also other notes on brain activity going on during the games, showing that males had much more brain activity going on throughout the game than the women did. I thought this difference in brain activity, though only garnering a quick mention in this brief summary of the study, might be of use to my research.
