Er - the PSTH / FIR is selective averaging, but allowing for overlap
of response between the events of interest, and allowing for other
effects in the model. I think all you are seeing is that, if you
don't allow for either the other effects in the design, or the event
response overlap, this will mess up your timecourses....
Best,
