Extrinsic motivation refers to external influences which drive behaviour.
These extrinsic motivators involve either a "carrot" or "stick":
- Carrot - reward - Behaviour is performed to gain an external reward such as money or recognition
- Stick - punishment - Behaviour is performed to avoid an external punishment such as a fine or criticism
Intrinsic motivation is generally more powerful and desirable than extrinsic motivation, but it depends on the situation.
