Code that makes sure the stimuli do not appear too close to each other

Hello gamze

here you see one way how to randomize two positions

Random Position of Stimuli (two different images)

Dear Forum, I’ve got a problem with coding a random Position for the Stimuli. I coded it the way it is recommended on the Psychopy help page but still I always get a ‘syntax error’. This is what I coded: if random()>0.5: targetpos = [-0.5, 0]#on the left else: targetpos = [0.5, 0]#on the right if targetpos = [-0.5, 0] targetpos2 = [0.5,0] else: targetpos2 = [-0.5,0] I put it in the ‘Begin routine’ section just as recommended by Psychopy. And that is the output I get: i…

Alternatively, you could create a lis tof x- and y-positions at the beginning of the experiment, randomize those and pick from the list.

Best wishes Jens
