Thank you, but will this work if I still want participants to go through every trial in the block? For example, if they get trial 1 incorrect in a block of three trials, I still want them to do trials 2 and 3, I just don't want them to experience the "reward" stimulus at the end of trial 3. The experiment also requires participants to go through several blocks in one session, will this work with your suggestion?

Thank you very much!
