I'm currently looking into different ideas for my dissertation at uni and being and being an avid gamer I am looking into trying to combine the two in order to give a better understanding about computer gaming and different aspects associated with it.
I'm currently studying psychology, looking to move on to do a masters or PHD in something regarding neuropsychology or psychopharmacology. Sadly as a undergraduate I don't think they are going to let me mess around with cognitive enhancing drugs as part of my 4th year project, however I can access other equipment for measuring the brain during activity.
One of my current ideas is looking at the brain activity after excessive gaming sessions. Speaking from experience I know myself and a few other friends who play games find it difficult to sleep at night after playing competitive games. It's almost as if you can still see different things in your head as you try and shut down to sleep, an example recently for me was seeing bloody Zerg drones constantly after playing SC2 for a long period. I would almost compare it to having closed eye visuals as if taking a small amount of hallucinogenic drugs but not nearly as strong.
I'm wondering if this is a common problem for a lot of gamers or just a small minority.
