HMain
effect: Regions showing presence of differences in activation due to
changes in
stimulus type (which differences must be determined via later contrasts)
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 subtler effects
HChoose HvsT (human versus tools) sub-bricks
ånote small range of t-values (subtler 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 (AKA
hypothesis)
åview
the Inter sub-bricks to determine if some areas for which the contrast (TM+HP)Ð(HM+TP) is significant
åHopefully youÕll find few/none, or be prepared to explain such
activations
