Carissa,

I can't think of an easy way to directly contrast the three correlations, but you may try this: run the following model

Y = a0 + a1*X1 + a2*X2 + a3*X3 + e

and you can directly see their differences in one model.

P.S.:

1) it seems possible to compare the correlations with 3dMVM, but that would probably involve some significant modulations in the progam.

2): it's fine to use 3dRegAna if you're comfortable with it, but the program is obsolete now since its functionality can be fully replaced by 3dttest++.
