I have 6 conditions, with 20 or 40 items in each condition. I need the conditions to be evenly distributed throughout the experiment, i.e. repeatedly sampling 1 or 2 items from each condition, presenting the selected items (in a randomized order), and then again sampling 1-2 new items from each condition (presenting these items, sampling again, and so on - until all items are used).
If i understand correctly, in an offline experiment this would be done by creating a python script that runs at the begging of the experiment, the script creates (and saves) a new items file, and then this item file is read in a loop.
How do I do this in an online experiment? can I save a file and read it?
I would also extremely appreciate any help with the script itself, since I don’t really know JavaScript…
Thanks!
