Bonus payments are additional payments you can make beyond the normal payment for a participant's submission. You can use these to allow for variable rewards, prizes, or to make partial payments to participant who have not completed your study but you still want to reward.

You can make bonus payments by selecting this option from the "More" dropdown while Viewing submisisons for your study.

 

Performance based rewards

You can pay participants variable rates on Prolific.

However, even if the rates are variable the minimum must agree with our reward per hour guidelines of > £5/hr. Bonus payments can then be paid in addition to the base reward based on performance.
