not sure whether this specific question about randomization has been asked before!
Nevertheless, my problem is as follows:
I have a variable called "item", and this variable consists of three items (let's call them item 'A', 'B', and 'C'). Each item will be presented for seven times (i.e., cycle = 7), resulting in 21 items in total.
I would like to have the first triad (here defined as three trials consisting of A, B, and C) randomized, and to use this particular order for the remaining six cycles.
So, if it turns out that the first triad/cycle is B, A, C, i would like to continue with this order for the following six cycles.
I am not sure how to implement this in Opensesame.
Can you help me out with this?
Thanks in advance!
