You would represent each presentation as two different conditions, one with a weight that is always 1, the other weighted according to your scale. So this doubles the number of conditions. You would then test the weighted conditions. The weight=1 conditions represent an intercept, and the weighted conditions model the slope.

And if I don't believe that? What changes would I need to make? I don't have a passive viewing condition to compare against, but it might equate to fixation as we are most interested in what occurs during the delay (which is the majority of each trial).

I'm not sure if that's exactly what I am saying. Basically,
there is an area in the brain (which I am trying to localize)
that tracks the number of items you are holding in memory so
that the more items you hold in memory, the higher the bold
activation. We have behavioral results saying how many items
people are holding in each of the conditions, and we want to
use this to get out an area in which the BOLD activation
mirrors this. In Brain Voyager, this is done by weighting the
conditions by the behavior, which is what I am trying to do
here. I'm not sure that that translates exactly into what you
are saying.

This
implies that the response amp is 0 when your weight is 0. If
that's not the case, then you need to make a modification.
Let me
know if you need that.

1. For looking at what shows up in the weighted

I want to see areas that increase along my weights, would I
just make a contrast of all of them vs fixation, and
then any

followed my weighting (if that makes sense)?

There are
weights of 0 for the couple conditions that were
essentially
throwaway trials for counterbalancing reasons.
Is that
what

whole numbers?

So if you

condition 1
will be
twice that of presentation B of condition 1, then
you would

weight of 2 for pres A and 1 for pres B. The
