So I created a weighted regression analysis to look at the effect of memory
load in a particular brain region. Basically, I weighted the paradigms by a
behavioral measure that reflected the number of items actually remembered
(as set size was increased). As far as Doug told me there are basically
I assume that you are comparing maps of Version1:1v0 and Version2:2v0 ?
I could imagine it going either way. If the true slope is 0 but the
offset is non-0, then Version1 will give you an artificially high slope
(and Verion2 will give you the correct slope at 0, and so no
activation). Are you c
You should also look at Version2:1v0. I bet a lot of the areas from
Version1:1v0 will also show up. You can also create a Version3 in which
you divide your presentations into a low-weight and a high-weight (but
set the weight=1). Then create contrasts of low+high and high-low. The
low+high shou
