Using data of previous subjects as a variable for counterbalancing
First of all, thanks for JATOS and for this great forum!
I am trying to create an experiment by using OSWeb. It starts with a questionnaire, and then A and B loops follow. Score of this questionnaire reveals tendency to a rare condition. Therefore, basically, there will be 2 groups of subjects and I want to compare their results.
My plan is to counterbalance the loops within those groups, and to do so, use the data of the previous subjects. To be more clear, it might be better to explain: let's say, Jonah started the experiment. He scored very low at the beginning so he (presumably) has this rare condition. Now he will take the A and B loops and script should counterbalance their order. However, only 1 of the previous 50 subjects, Audrey had this condition and her loop order was A-B. Therefore, I want the script to access the data of Audrey, and unlike her, I want Jonah to take B loop first.
Is it possible to access this specific part of the data from previous subjects, and if so, can I use this as a variable in the script?
Thank you for your help in advance.
