Hello again PsychoPY community! As I’m struggling to find an elegant solution to my problem, I wanted to once again reach out and ask for your opinions. I am creating some routines at the beginning of the experiment and these routines will serve as “Training” trials where participants learn associ…

Hello wakecarter is correct (thanks for the hint). This code results in an uneven distribution of participants across conditions. I repeated an error I did earlier (see link above) if int(expInfo['participant'])% 6 == 0: conditionFile = "conditionFile6.xlsx" elif int(expInfo['participant'])% 6…

Hello an easy way to counterbalance is specify all intended combinations (shapes, sounds, reminder routines aso.) in an Excel-sheet and read the needed lines based on, for instance, the participant number. BTW, it is better style and the code is easier to maintain if you reuse a routine when only …

Hello @JensBoelte Thanks a lot for your quick reply! :blush: I followed your advice and put all the training / reminder routines in just one routine. Now, however, I have some other issues. So to first show you, here is how one Training routine looks like: [pic21] I made this Excel sheet which…

Hello, when you have six different condition-files which you would like to distribute evenly across participants, your number of participants needs to be a multiple of six :wink: The following code selects a condition-file on the basis of the participant number: conditionFile = "dummy.xlsx" if i…

Hi again @JensBoelte ! thanks a lot for sharing this code, I really appreciate it. I think I’ll also go back to having one shape & one story within a single trial. And I can still use my conditions file for counterbalancing. I am planning to put all the stimuli (say, all the shapes and sounds) in …

Hello, give this a try, it presents three shapes (triangle, rectangle, circle) with three visual stimuli (1, 2, 3) ConditionFile.psyexp (17.4 KB) conditionfile.xlsx (8.4 KB) Best wishes Jens

Hello @JensBoelte ! Sorry for the late response but, thank you so much! This actually helped a lot :slight_smile:

Please note that the code will result in a particular UNeven distribution of participants to groups. Please see my previous post about this code. [image] Random assignment of participants to groups Builder Hi Jens, In words, you’ve written: if divisible by 1 else if divi…

Thank you @wakecarter for the hint and thank you a ton for updating the code @JensBoelte I really appreciate it!

Hi! Just to check, the code should be added to the ‘before experiment’ part, right? Thank you (have a similar problem as OP!)

Also I think there’s a typo in the last ‘participant’ :slight_smile: ( @grimfandangosh if you haven’t noticed)
