Aser,
of course it does - if you change your design, it will change the
results. This is particularly true if you add regressors that explain up
to 80% of the variance in the data, such as motion regressors. Besides
trying for yourself, I recommend reading Friston et al., MRM 1996, for
the basic concepts, and humbly suggest Wilke, NI 2012, for some more
explorations and simulations.
Cheers,
Marko
