overjustification effect

Explanation:

The motiviation usually ocurrs for intrinsic or external factors.

To achieve a particular goal, externally factors tend to be greater

As the overjustification founded in 1971, Deci with a minimal incentive like rising salary or giving money the behaviour will continue indefinetely.

In other words people are more willing to do something and keep doing it increasing the money rewars or external rewars.

However with the increase of this incentive, the authonomy of the individual is severy compromised, and therefore when this external motivators are removed the gettim them to like it and doing it will be highly less probable.
