Hello! I need some help with my experiment. I have a sequence of stimuli: a fixation cross, a digit and 2 images. I need images to be shown up randomly and simultaniously. I uploaded an excel file with 2 columns pic1 and pic2, which have absolutely the same sequence of the pictures. I wrote “$pic1” and “$pic2” in “image” and “image_2” petrospectively but when I ran the experiment I have 2 same pictures displayed while I need them to be displayed randomly.
I think I need to use some coding here but I have no idea what should I write there.
