Hello everyone,
I have an experiment which takes place over two separate days, where participants are randomly assigned to one of three conditions (treatment1, treatment2, and control). There are two experiment files for each condition for each day (6 in total). How do I make sure that if a subject was assigned to the treatment1 condition on the first day, they will also receive the follow-up experiment file for that specific condition on the second day? From my understanding, I will have to manipulate code in the batch script and include code related to group number. However, I am unsure, and would greatly appreciate the help as I am planning to run this on prolific.

Here is the batch script for Day 1 so far: 

<batch>
/ subjects = (1 of 3)
/ groupassignment = subjectnumber
/ file = "Treatment_1.iqx"
</batch>

<batch>
/ subjects = (2 of 3)
/ groupassignment = subjectnumber
/ file = "Treatment_2.iqx"
</batch>

<batch>
/ subjects = (3 of 3)
/ groupassignment = subjectnumber
/ file = "Control_3.iqx"
</batch>

Thank you for your time,
Kemp
