Between-Subjects design
in OpenSesame
This is actually a really dumb question but for some reason I cannot find online material on a pure between-subjects design so I figured this would be the easiest way.
Basically, I just have condition 1 and 2 and some trial connected to it.
So I have a loop with only a condition variable that randomly chooses 1 or 2.
I then have a sequence item which runs loop condition 1 if condiiton=1 and 2 if condition is 2.
However, the way it is now it runs condition 1 and 2 after each other just in a random order...
I think this must be an easy fix but idk how and its been a long day ![]()
Thnx for the help in advance!

Hi Eva, what is it that you want to accomplish?
Your Condition loop item will output condition = 1 and condition = 2 in random fashion, so it's logical that Condition1 and Condition2 are randomly run, right?
Or do you mean you'd want to have the possibility that condition1 is run more than two times in a row? (In this case you could let your Condition loop item consist of a whole column of 1's and 2's, rather than just a single 1 and 2).

No I just want to have either condition 1 run or condition 2. Since I dont want participants to be in both
Ok just solved it. All you need to do is to put in the loop the "repeat" from 1 to 0,5. it counterintuitive but it works
