Rookie IAT question
I guess that maybe somebody has asked about this before but I can't find it on the forum... so sorry if that is the case.
I'm designing an IAT experiment with Open Sesame 3.1.7, and this is what I want to do.
My IAT experiment has to be divided into 4 different blocks displayed in random order: congruent, incongruent, congruent switched and incongruent switched. Inside each block, an instructions screen should be displayed followed by 15 trials displayed in random order. Each of the four blocks should appear three times (12 blocks in total).
I have the experimental design already done in Open Sesame, but I fail to set the random order for the four experimental blocks. Attached you can find a screenshot of my structure.
Any help would be appreciated!
