Great thank you, it works!
My actual table has 60 trials, this is why of the number is used.
Also, thank you for the warning about recruitment policies, we already did that and it’s fine as long as we pay for their time and they are informed from the beginning about the screening test.
I have another silly question.
I need block order randomization (no need to counterbalance).
I see that you suggested in another post to do something like this:
( Math.random()>=0.5 ? [ Sequence("intro","block1","block2","results") ] : [ Sequence("intro","block2","block1","results") ])
But what if I have more blocks and I need to randomized them between 4 orders?
Or even more, like 24 orders?
Do I use the same math.random function?
If this questions doens’t belong here, I can delete it and move it below a post with similar requests.
Thank you again for your help.
