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.
