Random Presentation of Visual Stimuli
Hi, I'm trying to build up an experiment consisting of the presentation of several stimuli, at least 72. A friend of mine recommend me to use this program, and I have built up the sequence successfully, but I didn't get to randomize the presentation. Any tips? I need to collect data before first July, so I must have the experiment ready as soon as possible... ![]()

Dear GuillermoTasero,
if you put your stimuli into Trials and those into a Block (let's call the object
blockfor now, you can then simply shuffle all trials in a block by callingblock.shuffle_trials()(see http://docs.expyriment.org/expyriment.design.Block.html#expyriment.design.Block.shuffle_trials). You can then loop overblock.trialsand present the stimulus in each trial. Make sure to also check out our example experiments to see this in action.Best,
Florian
Dear Florian,
Thanks for your quickly answer. I'm very appreciated. But I'm already pretty uselessness, and actually I'm not accustomed to computer language. I built up the experiment following the beginner instructions put in by default in the program tutorial. I thought it was enough for my purposes, and so I made a trial sequence as expected, put in a block and so on.
Pass on you a snapshot of the general view
Thanks again in advance!!
Dear GuillermoTasero,
you seem to be in the wrong forum. This is a forum about the Python package Expyriment.
I will move this to the OpenSesame forum for you.
Upss, thank you. I'll begin another thread as well
