What does overjustification effect example mean?
 The overjustification effect occurs when an extrinsic reward is introduced after a behavior that a person is already intrinsically motivated to perform. After working there a few weeks, you are no longer coming to your job because you enjoy helping people; rather, you view your job as 'work'. Your work at the counseling center is a means to an end - namely a paycheck. This is an example of overjustification effect.
