There were rats that had only had access to the food-access lever when super-hungry. Naturally, they learned that pressing the food-access lever was an awesome idea. Then they were shown the lever again while very full. They enthusiastically pressed the lever as before. But they did not enthusiastically open the food magazine. Instead (I imagine), they pressed the lever, then started off towards the now-accessible food magazine, then when they got close, they stopped and said to themselves, “Yuck, wait, I’m not hungry at all, this is not appealing, what am I even doing right now??”. (We’ve all been there, right?)
This is so relatable!
