Thank you for the clarification! I am, as you suggested, running the within-subject effects as separate models. However, I still have a question regarding this. Let assume for simplicity thay i have 3 r values per subject (rA, rB, and rC).
Firstly, if i wanted the overall effect regardless of video, should i input all 3 values or take the mean after r-to-z transformation and use that as input (i.e. rInput = (rA+rB+rC)/3) ?
Secondly, if I wanted a contrast of condition X > condition Y where rA and rB belong to conditon X and rC belondgs to condition Y, would it be correct to do (rA+rB)/2) - rC and use the resulting value as input.
Thank you once again for all your help, it has been invaluable!
Cheers,
Vasco
