Everyone responds to some form of bribery in life.
Bribery is the promise of something in return for doing something.
But bribery has a negative implication, whereas reward is a positive influence. Most children are not mature enough to accept personal rewards, so they may need material rewards. Material rewards can be effective to motivate a child to improve a behavior, grade card, or practice, but should not be used as the only means for improvement. The material rewards need to be phased out when no longer needed and replaced with personal or social rewards. Rewards for children need to be frequent, consistent and appropriate.
