Hi SPMers,
I would like to show age-related effects for a memory task and I am thinking if the conjunction analysis would be a rational approach. If in the group level model, I put age as a covariate to the "successful encoding" contrast, is it logic to conjunct these two contrasts (contrast 1: successful encoding, hit>miss ; contrast 2: successful encoding, hit>miss with age) and choose the "global" option?
Thanks in advance!
