I personally have never heard of any research done into the effects of distortion, although I don't think music could be solely blamed for anyone's mental state. Granted, there's a particular image that is portrayed with every different type of music, and people who love a certain style often want to emulate the grunge rocker, cowboy, or thug that is considered the stereotype of a genre. Classical music generally gives an air of sophistication and intelligence, and that may have a greater effect on one's mental performance than the music--one may already be able to get that A on a test, but listening to Mozart makes them want to be intellectual and more subdued than listening to Rancid.
Just my two cents
Good theory though--definitely worth keeping in mind next time I buy a cd.
