mice degens?

[frogstomp]

From Traheho's blog:

" Scientists were testing mice to see their behavior in certain situations. They locked the mice in cages and gave them two buttons. The Red button would give them some sort of pleasure (say vicodin or morphine for mice) 100% of the time they pushed it. On the other hand the Blue button would give them the same dose of the same drug but only 50% of the time. The other 50% they would get an electrical shock. The obvious logic would be after 5 or 10 pushes, one would push the Red button to get high all the time rather than risk getting the shock. To my surprise, this is not what happened. They found that the mouse was NINE times more likely to push the Blue button. (Now if your conclusion for why this happened was because mice like blue more than red then….. well your a moron) The reasoning for this was because they liked not knowing the outcome of a given situation. It was the closest thing to gambling they could get. They wanted the risk of getting the drugs, but also the shock."

wow if this is true. anyone have a anymore info or a link on this experimentt?
