OS (e.g. Win7):
PsychoPy version (e.g. 1.84.2):
Hi, I have to create an experiment with two variables: first variable, “prime stimuli”, has three conditions (we call it F, S and P); second variable, “triads”, has two conditions (left and right). There are 60 images of target objects, so I create 180 prime stimuli (60 for each condition) and 120 triads (60 for each conditions).
The experiment consists in a fixation cross, a prime stimulus and a triad. I have to show only 60 of this sequence.
In the Builder mode, how could I make Psychopy randomize the selection of a prime stimulus from each of the three conditions list, and then match the related triad, but rondomizing its condition (left o right)?
Thanks a lot for help.
