Dabbling with some Psychology

I've looked up some psychology stuff lately in the hope of finding something interesting for our thesis. First I fond this excellent list of cognitive biases that can perhaps help understand player behavior in any testing we might do in the future as well as providing us with an extensive vocabulary (like the lovely "von Restroff effect").

Then i stumbled upon this - a document describing the use of a so called Attribution Style Questionnaire in evaluating athletic performance. Could not help but thinking that this approach would be very helpful in adjusting the challenge level when game testing in order to account for both hardcore and casual gamers (and their respective attributive styles). Something worth looking into for DICE and EA perhaps?
