Okay, so there are 5 CONDITIONs that each subject completes:
Stop
UpLeft
UpRight
DownLeft
DownRight
I would like to examine a couple of contrasts here:
(UpLeft +UpRight + DownLeft + DownRight) > Stop
(UpLeft + UpRight) > (DownLeft + DownRight)
(UpLeft + DownLeft) > Stop
Then I would like to examine whether the differences in these contrasts vary over GROUP at the two applicable timepoints after treatment (Immediate and 6Month), for instance:
Controls((UpLeft + DownLeft) > Stop) > Patients((UpLeft + DownLeft) > Stop)
Then I would like to do a GROUP x TIME interaction effect for the contrasts listed above (Including the 6Week scan that the Patients got but the Controls didn't?).
Then I would like to look within the Patient group to try and characterize a timecourse of recovery from treatment, asking specifically if the change is linear over time after treatment:
Patient-Immediate(SomeContrast) > Patient-6Week(SomeContrast) > Patient-6Month(SomeContrast)
Besides these, I'm sure I could come up with plenty of other meaningful contrasts... but these are the specific hypotheses.
Thankyou for your help! I'm not THAT scared of R, by the way... if I should be doing this in R, that's okay, but some help on how to set it up would be awesome.
You guys are the best.
