I’m working with psychopy builder (version 1.90.1) in a recognition task of weapons in different contexts. I would like to randomize the presentation of the stimulus, but the problem is that every picture has its own size and its own polygon attached to it, so I can’t create a file containing all pictures. How could I randomize the presentation since the begining without creating a loop? I need the randomization to be present from the first presentation of the stimulus.
Hello, you need to actually describe your experimental design and its constraints to us. “Randomisation” can mean an immense number of things.
