Hi
I am attempting to replicate results produced using SPM and need a bit of
help running an ANOVA on my contrasts.
Basically my experiment has been designed so that I can look at recogntion
memory for faces and scenes across three levels of response category. I
have already produced images of parameter estimates for my conditions of
interest, now I need to put these into a ANOVA to identify if there are any
main effects and interactions.
My 6 conditions of interest are as follows
facerec
facefam
facecr
scenerec
scenefam
scenecr
.. a 2x3 ANOVA because of 2 factors for stimulus (face, scene) and 3 levels
of response category (rec, fam, cr).
How would I model this in a higher level feat analysis in order to identify
whether I get main effects of stimulus and response catgory that I can
investigate further with subsequent contrasts. e.g a main effect of
stimulus face>scene (across stimulus type). I have looked on the help pages
but I am still unsure?
In addition to this, if I was to find some kind of signicant interaction how
would I set up a contrast to follow this up..? e.g. scene>face x rec>fam or
scene>face x cr>fam or face>scene x rec>fam or face>scene x cr>fam?
Any help with this would be greatly appreciated
Cheers
Hilary
