My experiment uses a list of 20 items from 1 to 20, from which numbers are randomly selected. How can I store the randomly seleected sequence. I simply want to know, whether the selected sequence was 3, 5, 17, ... or 1, 2, 8, 19 etc.
I did not find anything regarding this in the forum, which suprises me. Can someone help?
<list trial_sequence>
/items = (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
/selectionmode = random
</list>
I unsuccessfully tried things like:
<summarydata>
/columns = [list.trial_sequence, list.trial_sequence.items]
</summarydata>
Optimal solution: A column, which simply saves the order in summary data, for example: "1, 3, 16, 17,...". Or must I do a workaround, e. g. by defining 20 values and saving the corresponding position, e. g. by an additional counter?
Background: My experiment runs through the same block 20 times, each time with different stimuli. I have accomplished doing this by creating lists and to call the correct element with a value that I have called current_list. Most likely I can achieve the same thing with the counter element, but I also don't know how to save the sequence there, too.
