Can I provide 4 different feedbacks to 4 different responses from subjects?

In one part of my experiment, I have to record a string of input generated from the subjects. After the subject has pressed any of the 4 keys (4 different responses), can I give corresponding different feedback?

I only find ways to give feedback to 2 different responses (“correct” and “incorrect” responses).

Can anybody help? Thanks.

Unfortunately, you are right. Feedback can be provided only based on correctness or reaction time.

Feedback can be provided only based on a correct response, incorrect response, or reaction time.
