¥3dANOVA2:
viewing results
HMain
effect: Regions showing difference in activation due to changes in stimulus type
åview StimEffect
sub-bricks for function and threshold (F-stat = 15, p =10-5)
HFactor
Means: Activation in response to each category
åview TM,
HM, etc. sub-bricks (t-stat = 10.6, p = 10-10)
åall
categories appear to activate same areas
HChoose
AllAct sub-bricks for finding regions activated by at least one of the
stimuli
åthis
region of activation is often used to select an ROI which is examined for subtle effects
HChoose
HvsT (human versus tools) sub-bricks
ånote
small range of t-values (subtle effects, if any)
ålower t-stat
threshold to 4, p ~ 5x10-4
åmight
want to restrict hypothesis testing to region activated by stimuli
HLook
for interactions that might complicate your fairy tale
åview
the Inter sub-bricks to determine if some areas for which the contrast ( TM + HP ) Ð ( HM + TP ) is significant.
åHopefully
youÕll find none, or be prepared to explain it.
