Paradigm of overjustification:

Lepper, Greene, & Nisbett (1973)--in the reader. In this situation, children who already like to draw
receive an additional reason why they do it ("overjustification"), namely, an award. Under this new
self-interpretation, they don't draw anymore because they like it but because they want their award; as a
result, their drawing is less fun (and less good).
