When I am hungry or bothered or annoyed, I am more likely to say "no." I'm having trouble reading the article (they've disabled the up- and down-arrow to scroll for some insane reason), but the one test I can see is having subjects inflate a balloon, giving them more rewards the bigger they inflate it, but nothing if it pops. The lesson is "don't get too greedy." When I am hungry, I'm not going to keep on guessing as to how far I can push something. I'm going to stop early.
