I have two types of primes (as text: prime1, prime2), in total 20 (10 each type). Then, I have 120 text stimuli, 60 per each type of prime. In one block I would like to present a random prime and then 10 random stimuli, belonging to the prime type (1 or 2), with no repetitions between the blocks. I created two files: primes1.cvs and primes2.cvs as well as items1.cvs and items2.cvs. Please help me procede. Maybe I should also create some conditions file like Combinations.cvs? So in a nutshell: every prime should be random and within the prime type stimuli the 10 stimuli should be randomly chosen.
Many thanks in adavance.
