How to add counterbalancing to a study
I am using a pattern separation task, for which there are 6 versions prebuilt into the main coding.
In the study, participants will come in for a visit and complete the tests, then have a study drink, and then complete the test again. This is repeated across 3 visits (so they complete the test 6 times). I am looking for a way to counterbalance these 6 versions, so the participant doesn't complete the same version twice.
Normally in other software I use, we can just create 6 versions of the test and load them up individually using batch sessions. But, for JATOS I am struggling to find a way to create this.
Any help would be appreciated!
Thanks

Hi PsychStudent10,
There are a few different ways you could do this, especially if you want to make this happen automatically. But because you are testing in person, and because it sounds like it's possible for you to simply create 6 versions of your task, then you can also do that in JATOS.
In your place I would:
Does this answer your question?

Hey Elisa. Yeah that helps! I was wondering if I could just clone the study, but wasn't sure if it affected the UUID - but I realise now that it creates a new one which is great.
If I was to make this happen automatically, how would I be able to do this? Do I need to add in additional code for batch sessions, and determining which participant ID had already done a specific study version? If that made sense.
I've managed to do the cloning version for the time being!
Thankyou
Hi, yes, that's exactly what you'd need. You can search for 'randomise' in the example pages https://www.jatos.org/Example-Studies and you'll find two studies that might help as templates
Legend! Thank you. I will go through those examples now and dig out the appropriate code
Thank you for your swift response
