I don’t think the result was that they got bored of it while it was producing rewards, it’s that when the reward stops coming, they very quickly stop the behavior. If you have unpredictable but net-positive rewards, then you keep pulling the lever for longer when it stops paying out. So if you want to train a dog or other animal with a clicker or just with treats, the optimal strategy is probably not to give them treats every time they do the behavior.
