Hi Dave,
I was hoping you could help me with the affective priming task I'm trying to run (script attached). I want to show each target word (unpleasant and pleasant target lists) once with each prime (CSpos and CSneg prime lists) - so there would be 10 positive words with CSposprime item 1, 10 negative words with CSposprime item 1, 10 positive words with CSposprime item 2, 10 negative words with CSposprime item 2 etc. for a total of 80 trials. The trials are written in congruent and in-congruent trials - pleasant prime with pleasant target (congruent) and pleasant prime with unpleasant target (in-congruent) etc. The 4 trials are then blocked so that presentations of each can occur randomly (so I'm not showing all congruent trials in one hit). The 80 trials are shown, but some CSprime's are presented more than once with the same target word, while some CSsprime's are not shown with a particular target word, which is not what I want. Is there a way to keep the randomising occurring, but to present each prime with each target word only once?
Thanks,
Luke
