I am having a problem with setting three different kinds of digital outputs in my task-switching paradigm.
To explain shortly about the task before anything, it's deciding whether the number given is more/less than 5 OR the number given is even/odd.
The change of this criterion is indicated by the rectangle surrounding the number.
I am planning to do an ERP analysis on
1. pre-switching trials(1st,2nd,3rd trials before rule change(rectangle))
2. switching trial itself (rectangle one)
3. post-switching trials (1st,2nd,3rd trials after the rule change(rectangle))
regardless of the changing criterion.
but this stimulus grouping(stimulus list) makes it harder to set digital outputs into certain trials inside the list
I have attached my file as it is complex to say it into words. (I also included the schematic of the experimental paradigm)
Thanks in advance.
