Thank you so much Anderson!
Hello all,
I have a quick questions.
On individual level, I have 3 EVs, male faces, female faces and objects. Now I want to pool male faces and females faces' response and compare them with the objects (so FACES vs OBJECTS). Should I do [1 1 -2] or [0.5 0.5 -1] or [1 1 -1]? Does the first and second contrast set up differ?
Thanks,
Kim
