Quizplus · Accepted Answer

The overjustification effect is the tendency for extrinsic rewards to undermine intrinsic motivation, meaning that when people are rewarded for doing something they previously enjoyed for its own sake, they may become less motivated to do it in the absence of the rewards. This can happen because the rewards can shift the focus from the enjoyment or satisfaction of the activity itself to the external outcome or incentive.
