Dear CONN Experts,

I have re-evaluated my original question and I am concerned it might have been based on wrong assumptions (actually based on a misleading AI summary). Hence, I would like to ask whether it is valid to use a design described in my original post (mixed 2x2 ANCOVA design with subject effects [1 -1 0] and between-condition contrast [1 -1], in which the additional covariate represents a behavioral change between session 1 and 2) as it is. Could you confirm that CONN evaluates both sessions simultaneously using multivariate statistics? If so, no session-specific covariate would be needed.

Kind regards

Pavel Hok
