RE: Design matrix and contrast for 2x2 design
In short, yes. For further details, please check out some of the previous posts here on a 2 x 2 design with an interaction effect and repeated measurments.

Thank you so much for the answer!
So given I want to investigate an interaction effect, I would need to remove the drug condition afterwards?
Meaning a design matrix like this:
Drug | Rating | Participant columns ...
0 3.2 1 0..
0 -1.8 1 0..
1 1.2 1 0...
1 -9 1 0...
1 -4 0 1...
first 4 rows denote first subject, 5th row 2nd subject
would become
Interaction | Participant
0 1 0...
0 1 0..
1.2 1 0...
-9 1 0..
-4 0 1
Thank you so much!
