An experimenter visits a preschool with a big box of markers and paper. The children are told that they can draw as many pictures as they want. The children enjoy the task very much. On another visit, the children were told that, for every picture they drew, they would earn a prize. Two weeks later when the experimenter returned, he offered up the markers and paper for play but said that no prizes would be given. The children played very little with the markers because:

extrinsic rewards can undermine intrinsic motivation.

Explanation: In today's world we have been exposed to doing something because you will get something in return and this kills that personal and internal motivation in which one does something only because they love doing it and jt makes them happy.

The children were first motivated by the reward that they got and that stayed in their mind ,now it is hard for them to change their mind to being motivated only by the love of drawing.
