Hi there,
I have two lists of stimuli which a variants of each other (e.g., list A contains faces, list B contains the same faces inverted, etc). During one block, I want to make sure that if stimulus 1 has been randomly selected from list A, it will not be selected from list B at any time during this block.Counters and different select options seem to allow only to make sure that the same stimulus is not selected in the consecutive trial but not throughout the whole block, right? Any clever way to implement such conditional stimulus selections?
Many thanks for any insight,
Juliane
