I came across an interesting term "contrafreeloading" in Dan Ariely's "The Upside of Irrationality."
Explanation from birdchannel.com
Contrafreeloading: (verb) The behavior in which animals offered the choice between eating food provided to them for free or working to get that food would eat the most food from the source that required effort. This term was created in 1963 by animal psychologist Glen Jensen. Jensen ran a study on 200 male albino rats where the end result was the rats ate more from the food source where the rats had to press on a bar to get the pellet rather than the dish of pellets where they didn’t have to do anything at all. Jensen then studied the behaviors of gerbils, mice, birds, fish, monkeys and chimpanzees. In fact many have studied contrafreeloading since then with similar results, except for the domestic cat – which likes to be served. This 1963 study’s results were surprising because it would be more logical, from an evolutionary point of view, to not expand energy to get food when food is freely available.
I started wondering if there is a connection. How about humans? Do we exhibit contrafreeloading too? I doubt adults do, at least when it comes to food. But perhaps kids do? Should try some experiments at home!

Interestingly, I read about this on the same day our 1 year old decided she'd run around and around her high chair, instead of sitting on it, while taking one spoon of her dinner per round. We found it funny, and also satisfying since she ate more.
