Good morning, I would need a clarification of the exact meaning of the "effect of interest" use to adjust the extracted eigenvariates.
Is it all conditions which are convoluted with the HRF or only the one of interest regarding to the task?
For exemple: I have three modelized conditions : GO, NOGO, Wrong responses. The last one doesn't interest me (no hypothesis to test). The F-contrast of "effect of interest" used for adjustment should be
1) [1 0 0;0 1 0; 0 0 1]
or
2) [1 0 0; 0 1 0; 0 0 0]
?
Thanks
