Answer: Intrinsic Motivation
Step-by-step explanation:
People who get paid for an activity are less likely to repeat that activity of there is no more reward as opposed to people who have been doing that same activity without payment.
This shows that EXTRINSIC motivation can undermine Intrinsic Motivation.
It is for this reason that extrinsic motivation is not recommended for certain activities but rather positive feedback which has been shown to contribute to INTRINSIC Motivation.
