Hi SPM users
Each subject in my study experienced 4 conditions. I want to evaluate the difference between conditions in the following manner:
(Condition1 > Baseline 1) > (Condition2 > Baseline 2)
For the second level analysis, I used a full factorial design (1 factor = condition, and 4 levels [condition 1, baseline 1, condition 2, baseline 2]), and I want to know how to set up my contrast. The most plausible ones that SPM automatically gives would be t-contrast [1 1 -1 -1] or [1 -1 1 -1], but not sure if these contrasts are testing what I want.
Any suggestions?
Thank you in advance for your help!
