I am trying to see effects of a treatment using ERPs. Each person
participated in two interventions, where EEG was recorded before and after
each intervention. So, I have a repeated measures two-way ANOVA design
where treatment (2 levels: Placebo, Active) and session (2 levels: pre-,
post-) are the two factors.
I have read the tutorials on using Cluster-based permutation tests on event
related fields (
to test interaction effect (
by Eric Maris on how to test main and interaction effects of a 2x2
I have selected a time period a-priori where I want to check the

can I do the post-hoc tests to identify which treatment made the
difference, and if the pre-sessions are similar?
