Answer: An example of extrinsic motivation is hitting a punching bag so you'll win your next boxing match.
Explanation:
Extrinsic motivation is a term for behavior that is driven by a certain external reward. Instances of external rewards include money, fame, other people's approval, praise, etc. It should be distinguished from intrinsic motivation, which includes our hobbies and something we want to do out of pure pleasure. Reading a book for pleasure, going to your job because you enjoy the work, or making arts and crafts to decorate your bedroom are all examples of intrinsic motivation.
When we do something out of extrinsic motivation, we do it because we expect that we will somehow be rewarded. In this case, if one practices hitting a bag and eventually wins his/her next boxing match, he/she will certainly get some kind of reward.
