Hi,
I have a rather general question about second level FE analyses:
Is it legitimate to run a within-subject FE analysis across sessions with slightly different paradigms and tasks?
Background: We have 3 session per subject (n~30) and each session was recorded under a slightly different paradigm / task. However, the sessions share certain main EVs and we were thinking to run a FE for these to get more robust and somewhat context-independent results.
I can see that this will all depend on whether the assumption of a context-independent component to each run holds true but other than that does a FE in such case sound ok? Or would people strongly favor a 'conjunction'-type of analysis here?
Thanks + cheers-
Andreas
